Behind the answer

Where your location details come from

Different questions need different maps. Here is what each answer means, where it comes from and what it cannot tell you.

Your approximate location

Cloudflare estimates the city, region, country, coordinates and time zone associated with the internet connection reaching this site. The IP address shown is the address of that connection. This may be a VPN exit or a mobile network location. It doesn’t show where you are standing.

The estimate arrives with the current request when available. Cloudflare’s visitor location documentation describes the supplied fields. Nothing is substituted for a missing city or region.

City, county and ZIP area

US state and county boundaries come from the US Census Bureau. These use 2025 geography; the ZIP areas use 2020 geography. City and town boundaries use the 2025 American Community Survey geography. City search uses a representative point from the 2025 Census Gazetteer.

A representative point is inside the named place. It is not a street address or an entrance. Boundaries are simplified, so small gaps can occur. A nearby ZIP outline is clearly labeled as nearby instead of being presented as an area containing your point.

A Census ZIP Code Tabulation Area groups addresses for statistics. For mail, confirm the delivery ZIP with USPS ZIP Code Lookup. For tax, voting or jury forms, confirm the jurisdiction with the office responsible for the form.

Where a ZIP area crosses county lines, its page gives each county’s share of the ZIP area’s land from the Census 2020 ZIP Code Tabulation Area to county relationship file. The shares appear only where every county the page lists is in that file for the ZIP area. The file uses 2020 counties, so ZIP areas in Connecticut, whose planning regions replaced its counties in 2022, show none.

Census geography is public-domain US government data.

Street addresses

When you press “Find address”, the address goes from your browser to the US Census Bureau’s Geocoder, which compares it with the house-number ranges in its TIGER street files (the current Public_AR_Current benchmark) and answers with the address it matched, a point and the county from its full-detail boundaries. The point is placed along the block from the range of house numbers on that side of the street, so it can sit a few lots from the building; drag the pin to correct it. The Geocoder covers the United States, Puerto Rico and the US Island Areas, and street addresses only: a PO box, a business name or a new street may not match. Its service documentation (updated February 2026) was checked on October 23, 2026.

The city, ZIP area and time zone for that point then come from the same boundaries as any other point. If the Census Bureau’s county differs from the simplified outline here, the answer says so and names theirs.

Time zone and local time

Physical time-zone boundaries use timezone-boundary-builder, release 2026d. Local time and UTC offsets use IANA tzdata 2026f for 2024–2029; dates outside that table use your browser’s clock rules. Your device’s own time-zone setting is shown separately where relevant; it may differ from the selected point.

Time-zone geography is adapted from © OpenStreetMap contributors under the Open Database License (ODbL 1.0). The boundaries are simplified and divided into local map areas; the modified geography remains available under that licence. Updated October 2, 2026.

Clock rules can change. Keep your browser and operating system up to date, especially after a government announces a time change.

Ground elevation

When you request elevation, the selected coordinates go to the USGS 3D Elevation Program through its Elevation Point Query Service. It estimates ground height, not the floor you are on or your phone’s altitude.

Missing heights remain unavailable. Small heights keep their sign; feet and meters use the exact conversion of one foot to 0.3048 meters. A fresh query does not make the terrain survey new. The result includes terrain cell size when supplied, which is not a guarantee of height accuracy.

USGS data used here is public domain. Service information updated September 19, 2026. Your device point is sent when you press the elevation button, or when you choose device location on the dedicated elevation page. That page states this before the request. Place profiles also show a precomputed height at their public Census representative point, from the USGS 3DEP terrain service. The nominal terrain-cell spacing comes from the USGS product label, and the vertical datum is retained when supplied. Some products use angular spacing in arc-seconds; a raw service resolution is not assumed to be meters.

Outside the United States, the elevation button reads the Terrain Tiles open dataset on Amazon Web Services instead. Mapzen built it from national and global terrain models (its list of sources): SRTM, NASA’s radar survey of February 2000, on most land; EU-DEM in most of Europe; national models in Norway, Austria, the United Kingdom, Canada, Mexico, New Zealand and parts of Australia; ArcticDEM north of 60°; GMTED2010 where nothing finer covers a spot; and NOAA’s ETOPO1 for the depth of the sea. Version 1.1 was released in late 2017, and no regular updates are planned, so a fresh request does not make the terrain newer.

Your browser fetches the one map image (zoom level 12) that holds the point, decodes the heights of the four nearest pixels and blends them. A pixel is about 38 m wide at the equator and 19 m at 60° latitude; that is the map’s grain, not a measure of how accurate the height is. The answer names the models that drew that map square. The models measure from sea level in their own ways (SRTM, for one, uses the EGM96 geoid), and none of them is a surveyed height. SRTM and GMTED write open water as zero and ETOPO1 fills it with depth, so a height below sea level in a square ETOPO1 helped draw may be the sea floor, and the answer says so; land below sea level, such as the shore of the Dead Sea, keeps its minus sign. The images stop at 85.05° north and south, so the button stays off nearer the poles.

Place elevation

Place pages retain the existing 3DEP terrain estimate at the Census point when available. Other heights come from the USGS national GNIS archive, joined by the Census Gazetteer’s GNIS identifier. The archive is from August 2021. A GNIS height belongs to its named reference point, which may differ from the Census representative point. It is not an average or a surveyed height for the whole place. Missing heights stay unavailable.

National parks and named beaches

Park names, official links and representative points come from the National Park Service. Beach names and map reference points come from the USGS Geographic Names Information System. These are public-domain US government sources.

Distances are straight lines to representative points, not driving distances or routes to entrances. When a named beach has several reference points, the nearest supplied point is used for both the distance and the destination link. The beach records don’t say whether a beach is public, when it’s open, whether it’s safe to swim or what kind of shore it has. Check with the park or landowner before you go.

Weather at a point

The weather page asks two public services from your browser, only after you choose a point. MET Norway’s Locationforecast gives the current hour, the next hours, the day’s range, wind, humidity, rain or snow and the clear-sky UV index anywhere in the world, under CC BY 4.0; we show its figures in words and US units. For points in the United States, the National Weather Service API adds active alerts and the local forecast office’s text for today and tonight, which are in the public domain. Coordinates go out rounded to two decimal places. The UV words follow the World Health Organization’s UV index scale.

The world overview map

Land, country and first-level regional outlines, together with city labels, come from Natural Earth. They are generalized for recognition and the country-at-a-point answer. They do not decide county or ZIP boundaries and cannot settle a disputed border. Natural Earth makes this geography available in the public domain.

Country names, capitals, areas, currency and language information come from GeoNames, used under CC BY 4.0. Natural Earth supplies country maps. The country list excludes historic entries that do not describe a current country. Updated 2026-09-19.

GeoNames gives no year for its country populations, so the country pages show them as GeoNames figures rather than current estimates. Where a government names a different capital or several capitals with roles, its own profile is used: Sri Lanka (Sri Jayawardenepura Kotte, administrative) and South Africa (Pretoria, Cape Town and Bloemfontein). Where GeoNames still uses a capital’s former name or place, Wikipedia’s current one is used: Astana, Kazakhstan (not Nur-Sultan), and Ngerulmud, Palau. XK, the code GeoNames uses for Kosovo, is not an official ISO country code.

Place and county maps

The Census Gazetteer supplies official identifiers, representative coordinates and land/water areas. TIGERweb supplies geographic boundaries. The Census records use 2025 geography; ZCTAs use 2020 boundaries.

Relationships describe positive-area overlaps between the source polygons. Boundary simplification can create small gaps or overlaps. Population estimates are not shown without a validated Census estimate and its reference year.

County population and government websites

Resident population is the July 1, 2025 estimate from the Census Population Estimates Program. It describes people living in the county, not daytime visitors or the size of a city. These are population estimates, not ACS survey estimates; ACS margins of error do not apply to this series. Puerto Rico’s municipios are not in that file; their July 1, 2025 estimates are the Census Bureau’s municipio estimates of the same vintage, checked on October 20, 2026. The other island areas have no population figure added. Updated 2026-09-19.

County website links use exact organization-and-state matches in CISA’s public government-domain list. Ambiguous matches are left out. Updated 2026-09-19.

Population, income, home values and rent for places and ZIP areas

Population for cities, towns and Census ZIP areas, and median household income, median home value, median rent and the share of homes lived in by their owners for counties, places and ZIP areas, are U.S. Census Bureau American Community Survey 2020–2024 5-year estimates (tables B01003, B19013, B25077, B25064 and B25003), read from the Census summary files. Each figure is shown with its margin of error at 90 percent confidence; the owners’ share is worked out from the counts of occupied and owner-occupied homes, with its margin from the Census formula for a proportion. A five-year estimate describes the whole period, not one year, and small places have wide margins. Income and rent are in 2024 inflation-adjusted dollars; rent is gross rent, the rent plus the utilities and fuels the renter pays, for homes rented for cash. The Census reports incomes above $250,000, home values above $2,000,000 and rents above $3,500 only as “or more”. Checked on October 13, 2026.

Seven places were renamed after these estimates, and the survey still publishes their figures under the former name: Fort Novosel, Alabama (Fort Rucker); Fort Johnson North and Fort Johnson South, Louisiana (Fort Polk North and South); Sčilíp, Montana (Dixon); Brinkhaven, Ohio (Gann); Fort Cavazos, Texas (Fort Hood); and Fort Gregg-Adams, Virginia (Fort Lee). Each has the same land and water area under both names in the Census Gazetteers of 2024 and 2025, checked on October 22, 2026. The Army gave four of these posts their former names back in June 2025 (Fort Rucker, Fort Polk, Fort Hood and Fort Lee, Associated Press, June 10, 2025, checked on October 23, 2026); Census had not yet renamed the places, so their pages carry both names.

County seats

County-seat names come from Wikidata’s capital statements, joined to Census counties by their FIPS codes. The structured data is available under CC0. Multiple current seats are preserved. Statements with an end date or deprecated rank are excluded; a place that later became the seat again needs a separate current statement. An explicit no-seat statement is different from a missing record; missing names are held and displayed as unconfirmed. Official exceptions explain combined governments and county equivalents. A government office or contact address is labelled as such, rather than treated as proof of a formal county seat. Independent cities are explained using the Census definition of county equivalents. Updated 2026-09-27.

New York City’s borough and county geography identifies all five boroughs and their corresponding counties.

Definitions, clock rules and calculations

Coordinate formats, distance circles and midpoints are calculated from the points you enter. Great-circle distances use a spherical Earth and do not include roads or terrain. Elevation profiles connect the heights returned for their displayed sample points; they do not describe unmeasured terrain between samples.

Sunrise and sunset are approximate calculations using the equations of NOAA’s Solar Calculator, at the place’s representative point and on its local calendar date. They assume a level horizon and standard refraction; hills, buildings and weather can change visible sunrise. Polar day or night is shown instead of inventing a time. Today’s times update in your browser as the date changes; the month-by-month times on place and ZIP Code pages come from the same calculation.

Country and time-zone associations

Country profiles use the country-specific identifiers in IANA’s 2026f country table, which is dedicated to the public domain. Its compatibility identifiers match the named boundaries used here. This prevents a small overlap between independently drawn maps from being treated as a country’s clock rule. IANA’s table is a practical clock-selection aid, not a statement about territorial claims. Unmatched country records keep their time-zone assignment unavailable. Updated 2026-10-30.

Cities, calling codes and driving sides

The largest cities on country and time-zone pages come from GeoNames’ list of cities with more than 15,000 people (CC BY 4.0), ranked by the population GeoNames gives, which has no year. A borough or district that GeoNames lists beside a larger city is left out, and names GeoNames writes with transliteration marks are shown in their plain English form (Herat, not Herāt). Calling codes come from GeoNames’ country information; the driving side is Wikidata’s (CC0), shown only where Wikidata gives one side. Checked on October 13, 2026.

School district, congressional and other area finders

These lookups use Census ACS 2025 boundaries. A county subdivision may have a different local name. School boundaries don’t decide which school a student attends, and metro areas are statistical groupings. Congressional districts use the 119th Congress geography. State legislative districts show the upper and lower chambers separately. Tracts are statistical areas. Tribal boundaries do not determine citizenship or sovereignty; consult the relevant tribal government. Confirm election addresses with the responsible election office.

Metro and micro areas

The metro and micro area pages list each area’s counties, central or outlying, and its principal cities from the Census Bureau’s lists of the Office of Management and Budget’s July 2023 delineations, OMB Bulletin 23-01 (counties, principal cities). Each area’s population on July 1, 2025 and its April 2020 base are the Census Bureau’s Vintage 2025 estimates for metro and micro areas; that series leaves out Puerto Rico, so its areas show the sum of their municipios’ estimates. The rules for central and outlying counties are in the 2020 standards. Checked on October 19, 2026. Public-domain US government data.

Cities that cross county lines

The list of cities and towns that cross county lines and the residents-by-county lists on those places’ pages use the Census Bureau’s split of each place by county (summary level 155) in table B01003 of the American Community Survey 2020–2024 5-year estimates, the same table that gives each place’s population. Each county part is an estimate with a margin of error at the 90 percent confidence level; a part with no residents counted is left out of the list and marked on the place’s page. Public-domain U.S. Census Bureau work. Checked on October 22, 2026.

Towns and townships

The town and township pages cover the 23,740 county subdivisions in the Census Bureau’s 2025 Gazetteer that have a government or a name of their own. Left out are the 5,541 statistical divisions (census county divisions and unorganized territories), the 4,822 that only repeat a city or borough with its own page, and the 2,324 districts named by a number or letter alone; the township finder still answers for all of them. Whether a subdivision has a government is the Census functional status. Outlines are the TIGERweb county subdivisions, simplified for drawing; areas that share a few hundred meters of boundary or more are listed as bordering. Population, income and home value are American Community Survey 2020–2024 5-year estimates, as for places. Checked on October 20, 2026. Public-domain US Census data.

A town or township with its own government links its website when CISA’s public government-domain list holds exactly one city or town domain with its exact name and kind in its state (“Town of Greenburgh”, “Hampden Township”), and the state has no other subdivision with that name; 1,609 pages have one. A registered domain with no live address is left out. Checked on October 21, 2026.

School districts

The school district pages cover the 13,345 unified, secondary and elementary districts and Vermont administrative areas in the Census Bureau’s TIGERweb school district layers, with the grades each serves; the “School District Not Defined” areas are left out. States report these boundaries to the Census Bureau each year. Every county with land in a district is listed, with its share of the district’s land, from the National Center for Education Statistics’ school district and county relationship file (school year 2024–25), which measures land on the Census Bureau’s full boundaries. A town or township is listed when at least half its area is in the district, measured on outlines simplified for drawing. Population, income and home value are American Community Survey 2020–2024 5-year estimates for everyone living in the district, not enrollment. Schools and enrollment are on the National Center for Education Statistics district pages each page links. An elementary district names the secondary (high school) districts the same layers draw over at least 2% of its area, water included, and a secondary district names those elementary districts. A district boundary does not decide which school a child attends. Checked on October 20, 2026. Public-domain US Census and Department of Education data.

Tribal areas

The tribal area pages cover the 704 American Indian, Alaska Native and Native Hawaiian areas in the Census Bureau’s 2025 Gazetteer, under their Census names. Each area’s parts (reservation, off-reservation trust land, Hawaiian home land, statistical or joint-use area) and outline come from the TIGERweb tribal layers of the same vintage, simplified for drawing; a county is listed when it holds at least 2% of what an area’s outline encloses, water included, and its share is measured the same way. Population, income and home value are American Community Survey 2020–2024 5-year estimates. These Census boundaries don’t decide tribal membership, jurisdiction or land status. Checked on October 20, 2026. Public-domain US Census data.

UK counties and local authorities

The county finder also checks the ONS county and unitary-authority boundaries for December 2025. This layer includes counties, unitary authorities and other local-authority equivalents. It does not describe historic or ceremonial counties. Coastal outlines are simplified.

County equivalents in Ireland, Canada, Mexico, Switzerland, Australia and New Zealand

Outside the US and the UK, the county finder answers from one national boundary file per country, read from the agency’s own map service and simplified to about 50 meters, so check a point near a boundary with the council or municipality. Ireland: the 31 local authorities of Tailte Éireann’s National Statutory Boundaries (2026), joined from the pieces the service holds for each. Canada: the 293 census divisions of Statistics Canada’s 2021 Census boundary files. Mexico: the 2,478 municipios and Mexico City alcaldías of INEGI’s geostatistical framework (Marco Geoestadístico, December 2025), which INEGI draws for its statistics. Switzerland: the districts in swisstopo’s swissBOUNDARIES3D as at 1 January 2026, and the cantons that have no districts (144 areas in all). Australia: the 548 local government areas and unincorporated areas of the ABS ASGS 2026 edition, the ABS’s approximation of the gazetted council boundaries from its mesh blocks. New Zealand: the 67 territorial authorities as at 1 January 2026, each named with its region from Stats NZ’s 16 regional council areas as at 1 January 2025, the newest on its map service; the Chatham Islands belong to no region. Checked on October 21, 2026.

Plant hardiness by ZIP code

The USDA 2023 map uses the average annual extreme minimum winter temperature for 1991–2020. The hardiness lookup displays the original ZIP classifications supplied by Oregon State University. A ZIP classification cannot settle a particular garden’s microclimate or a plant’s other growing needs.

The datasets are used under the OSU reproduction and redistribution terms. This tool does not create a derived hardiness map.

Coordinate formats and measurement tools

Coordinate representations, bearing angles, horizon distance, antipodes, sampled height changes and radius membership are our arithmetic from entered points and licensed geography. They are guides, not survey measurements.

Magnetic bearings use WMM2025 for the current date and zero height above the WGS84 ellipsoid. They are withheld where the horizontal field falls below 6,000 nanoteslas or the model has expired. Local magnetic interference and storms can change compass readings.

Radius results count the map points of Census places and ZIP areas inside the circle; they do not claim that whole cities or postal delivery areas fit inside it. Profile gain, loss and steepest grade describe only the sampled segments. Shorter hills between samples can be missed. The horizon calculation omits terrain, refraction and obstacles.

Elevation comparisons

A comparison guide, not elevation bands or a safety rating. Feet are the published units; meters are calculated as feet × 0.3048. The published heights are from USGS’s Death Valley reference.

Tectonic plates, active faults and volcanoes

Plate outlines, plate boundaries and plate motion come from PB2002: Bird, P. (2003), An updated digital model of plate boundaries, Geochemistry Geophysics Geosystems, 4(3), 1027, doi:10.1029/2001GC000252. Its author republished the model files in his 2025 archive under CC0 1.0, which places them in the public domain; we use the files from his site. A point is placed on a plate by testing it against the 52 plate outlines. Plate areas are the model’s published figures. Speeds and directions come from each plate’s rotation pole, moved into the no-net-rotation frame, in which the area-weighted rotation of all 52 plates adds up to zero; we calculate that frame from the model itself, and its Pacific Plate pole (63.2°S, 107.7°E, 0.649° per million years) agrees with the published NNR-NUVEL-1A pole (63.0°S, 107.4°E, 0.641°). Boundary types come from the model’s classification of every short boundary step: spreading ridges and rifts are divergent; oceanic and continental transform faults are transform; subduction zones and convergent zones are convergent. The plate answer makes one simplification: a convergent-zone or rift step where the plates’ motion runs within 30° of the boundary is told as transform, because the plates there mostly slide past each other; the model itself calls a step strike-slip only within 20°. The plate pages keep the model’s classes. Distances are straight lines over a sphere of radius 6,371 km.

Active faults come from the U.S. Geological Survey Quaternary Fault and Fold Database, a public-domain US government product. Faults count as active here if their most recent movement falls in the database’s “historic” class (movement in recorded history, such as the 1857 Fort Tejon earthquake on the San Andreas Fault) or “latest Quaternary” class (the past 15,000 years). Each fault links to its archived USGS report. Their traces are simplified to about 200 meters, and the database covers only the United States.

Volcanoes come from the Global Volcanism Program, 2026. [Database] Volcanoes of the World (v. 5.4.0; 7 Aug 2026). Distributed by Smithsonian Institution, compiled by Venzke, E. https://doi.org/10.5479/si.GVP.VOTW5-2026.5.4 This database is a product of US government employees with no copyright restrictions; its Holocene list holds volcanoes thought to have erupted or been otherwise volcanically active in roughly the past 12,000 years, and grades the evidence for each, from eruptions observed to evidence that is uncertain. We show each volcano’s name, location, type and last known eruption, say when its evidence is uncertain or only unrest, and link to its profile.

When you need a more precise answer

Choose device location and inspect its accuracy radius. A radius crossing a boundary means your position may not settle which side you are on. This site finds towns and coordinates, not street addresses. Use coordinates for a known point, and confirm consequential details with the responsible authority.

The privacy page explains which requests stay on this site and which choices send a point to an outside service.
