What Country Am I In?

Free country finder. Tap one button to identify the country at your current GPS location, or search any address, or click anywhere on the world map. The result panel includes the flag, ISO 2- and 3-letter codes, capital, region, population, area, currency, calling code, driving side, and primary language for 195 countries.

Country detection — and twelve other things you usually need with it

Most online country-finder tools answer the literal question and stop. You GPS in, you get a country name, that\u2019s it. We figure if you\u2019re asking "what country am I in?", you probably also want to know the ISO code (for any form you\u2019re filling out), the currency (for travel), the calling code (for a phone), the driving side (if you\u2019re driving), and the capital and population (for context). All of that is on the result card the moment the country resolves.

The tool also highlights the country polygon on the map in green, so you can see the shape and edges of the country you\u2019re in (vs. just a name). For coordinates near a border, that\u2019s the most reliable visual confirmation that the result is right.

How to find what country you are in

Five paths to the same answer; pick whichever fits your context.

1. Allow location access (or skip). Tap "Find My Country" — your browser will ask for permission to read your GPS. Granting it returns a result in under a second. If you prefer not to share location, skip GPS and use search or click the map instead.
2. Or search any place. Type a city, address, landmark, or postal code. The autocomplete shows matching places worldwide; pick one and the country resolves instantly. Useful when you want to look up the country of a specific destination, not your current position.
3. Or click anywhere on the world map. Pinch to zoom into the area you’re curious about, then tap. The country is detected from a point-in-polygon test against Natural Earth’s 50-metre boundary set, then the matching country polygon is highlighted in green on the map.
4. Read the result panel. The hero shows the flag, country name, ISO 2- and 3-letter codes, and continent. Below, a card grid shows capital, region, population, area, currency, calling code, driving side, and primary language. The exact coordinates of your point appear at the bottom of the hero.
5. Verify the city / region (when available). If the point is over land, OpenStreetMap’s Nominatim service is also called to enrich the result with the nearest city, state / province, and postal code. This appears as a secondary line in the hero panel.

What people use this tool for

Six recurring patterns we see in the analytics.

How country detection actually works

There are three approaches to "given a coordinate, what country is this?" The tool uses the first as primary and the second as fallback.

1. Point-in-polygon (primary)

We load Natural Earth\u2019s 1:50,000,000-scale country boundary set into the browser as a compact TopoJSON file. Each country is one polygon (or multipolygon for archipelagos like Indonesia). When you click or search, we run the standard ray-casting algorithm: cast a horizontal ray from the point and count how many edges of the polygon it crosses. An odd count means the point is inside; an even count means outside. The check runs in microseconds per polygon and is exhaustive across all 241 features in the dataset.

2. Reverse geocoding (fallback)

For points outside any 50-metre polygon (very small islands, sliver territories, the open ocean), we fall back to OpenStreetMap\u2019s Nominatim reverse-geocoder. Nominatim has finer coverage in many corner cases and returns a structured address with the country field. This is also where the city / state / postal-code enrichment comes from — even when the polygon match succeeds, we still call Nominatim to add the local-level context.

3. IP geolocation (we don\u2019t use this)

Many "country finder" services guess your country from your IP address. That\u2019s fast but wrong roughly 5–10% of the time (VPNs, mobile carriers routing through other countries, IPv6 oddities). We don\u2019t use IP geolocation; the result is always either GPS-precise, search-precise, or map-click-precise.

Country codes explained — ISO 3166, FIFA, and others

Every country has multiple short codes that identify it in different contexts. The tool surfaces the two most common (ISO 3166-1 alpha-2 and alpha-3) directly in the hero. Some background on each:

ISO 3166-1 alpha-2 (FR, JP, US)

Two-letter codes maintained by the International Organization for Standardization. Used in domain names (.fr, .jp, .us — though .us is rarely used; .com / .net dominate in the US), ISO 4217 currency code prefixes (EUR, JPY, USD), and Unicode regional-indicator flag emojis. The most common code you\u2019ll encounter on web forms.

ISO 3166-1 alpha-3 (FRA, JPN, USA)

Three-letter codes. Used by FIFA at the World Cup, by the International Olympic Committee (with some idiosyncrasies — IOC uses GER for Germany while ISO uses DEU), in passport MRZ zones, and by many international standards.

ISO 3166-1 numeric (250 for France, 392 for Japan)

Three-digit codes assigned by the UN Statistics Division. Stable across language and alphabet — a French database can use the same code as a Japanese one. Less commonly seen outside official UN / governmental data.

Other codes

FIFA codes (sometimes diverge from ISO — England, Scotland, Wales, Northern Ireland have separate FIFA codes despite being part of the UK in ISO). IOC codes for the Olympics. E.164 calling codes are different again (+1 for the US and Canada combined; +44 for the UK; etc.). Our tool shows ISO 3166 alpha-2, alpha-3, and the E.164 calling code.
