See the country and its ISO 3166-1 code, or an open-ocean result at sea.
How to Find the Country From Coordinates
Converting arbitrary latitude and longitude coordinates into an authoritative country name requires matching against global boundary datasets maintained by the United Nations, Natural Earth, and national cartographic agencies. Every recognized sovereign state and autonomous territory is codified under the ISO 3166-1 international standard, which assigns:
- Alpha-2 Code: Two-letter country abbreviations used universally in internet ccTLDs, banking, and shipping (e.g.,
US,CA,DE,JP). - Alpha-3 Code: Three-letter standardized designations used by the UN, Olympic committee, and international treaties (e.g.,
USA,CAN,DEU,JPN). - Numeric-3 Code: Three-digit numerical codes independent of Latin script alphabets (e.g.,
840for the United States).
Territorial Waters, EEZ and High Seas Explained
Over 70% of Earth's surface is covered by oceans. When entering maritime coordinates, determining which nation has legal authority requires applying the 1982 United Nations Convention on the Law of the Sea (UNCLOS). Coastal sovereignty extends outward in graduated zones:
Within 12 nautical miles, the coastal nation exercises sovereign territorial jurisdiction. Between 12 and 200 nautical miles, the coastal nation controls marine and seabed resources under its Exclusive Economic Zone (EEZ), while foreign vessels retain rights of peaceful navigation. Beyond 200 nautical miles lie the High Seas, outside any national sovereignty.
Enclaves, Exclaves and Disputed Borders
World political geography contains intricate anomalies where sovereign borders intersect:
- Enclaves within Foreign Territory: Baarle-Nassau (Netherlands) and Baarle-Hertog (Belgium) form a mosaic of 22 Belgian exclaves surrounded by Dutch territory, where borders divide individual shops and homes.
- Unclaimed Lands (Terra Nullius): Bir Tawil between Egypt and Sudan remains one of the few habitable places on Earth unclaimed by any recognized government.
- Antarctica: Governed by the 1959 Antarctic Treaty, all territorial claims south of 60° S latitude are frozen, dedicating the continent exclusively to peaceful scientific research.
How the Distance to International Waters Is Calculated
Calculating the distance from an offshore coordinate to the edge of territorial waters (12 Nautical Miles):
d_{\text{High Seas}} = \max\left( 0, \, 200\text{ NM} - d(\mathbf{P}, \mathbf{Baseline}) \right)- Step 1: Compute distance from vessel to nearest coastal baseline = 81.4 NM
- Step 2: Compare against 12 NM territorial limit: 81.4 > 12 -> Outside territorial sea
- Step 3: Compare against 200 NM EEZ limit: 81.4 <= 200 -> Within U.S. Exclusive Economic Zone
- Step 4: Distance remaining to International Waters: 200 - 81.4 = 118.6 NM (219.6 km)
The vessel operates under international freedom of navigation, but commercial fishing, oil drilling, and scientific research are governed by U.S. law.
Maritime Zones and Country Rights (Table)
Summary of national jurisdiction across marine boundaries codified by international treaty:
Maritime Zones under International Law (UNCLOS)
Legal frameworks governing navigation, resource rights, and civil sovereignty.
| Maritime Zone | Distance from Coastline | Sovereign Rights | Jurisdiction & Law |
|---|---|---|---|
| Internal Waters | Landward of baseline | Full national sovereignty equal to dry land | Complete domestic jurisdiction, no right of innocent passage |
| Territorial Sea | Up to 12 Nautical Miles (22.2 km) | Sovereign airspace, water column, and seabed | Domestic law applies; foreign vessels hold right of innocent passage |
| Contiguous Zone | 12 to 24 Nautical Miles (44.4 km) | Enforcement jurisdiction for customs, fiscal, and immigration | Right to punish infringements committed within territorial sea |
| Exclusive Economic Zone (EEZ) | Up to 200 Nautical Miles (370.4 km) | Sovereign rights for exploring, exploiting, and conserving resources | Coastal state regulates fishing, mining, wind energy; freedom of navigation applies |
| High Seas (International Waters) | Beyond 200 Nautical Miles | Common heritage of mankind; no sovereign ownership | Freedom of navigation, flag state jurisdiction under UNCLOS |
Coordinates to Country: Accuracy and Limitations
Users consulting coordinate-based country identification should note the following:
- Disputed Sovereignty: Dozens of global frontiers are disputed (e.g., Kashmir, Golan Heights, Falkland Islands/Islas Malvinas). Boundaries are presented for informational and cartographic purposes.
- Passports and Visas: Physical border entry points, passport checkpoints, and transit zones dictate legal entry, not raw mathematical lines.
- Airspace Control: National sovereign airspace corresponds to territorial waters (12 NM); civilian and military flight corridors require international flight clearances.

Quick facts about the coordinates to country converter
| Fact | Value | Notes |
|---|---|---|
| Sovereign Coverage | 195 UN Member & Observer States | Includes dependencies and territories |
| Standard Coding | ISO 3166-1 Alpha-2 / Alpha-3 | Official international country codes |
| Maritime Boundary | 12 Nautical Mile Territorial Waters | UN Convention on the Law of the Sea (UNCLOS) |
Edge cases and exceptions
International Waters (High Seas)
Points beyond 12 nautical miles from any sovereign baseline fall in international waters where no single nation holds territorial sovereignty.

Frequently asked questions about the coordinates to country converter
How do I find what country a GPS coordinate is in?
Input the latitude and longitude into the form or click the interactive map to query sovereign boundary polygons.
Are coordinates sent to any external server?
Calculations run privately with zero storage of your coordinate queries.
How do I know what country a latitude and longitude is in?
Enter the coordinates and the result names the country and gives its ISO code. The map shows the location for confirmation.
What are ISO country codes?
ISO 3166-1 defines two-letter (alpha-2) and three-letter (alpha-3) codes, such as US/USA, GB/GBR and BR/BRA.
What about coordinates in international waters?
Beyond a country's territorial waters there is no country. The result may indicate open ocean or the nearest territory.
What are territorial waters and the EEZ?
Territorial waters extend 12 nautical miles from the coast. The exclusive economic zone extends 200 nautical miles, where a country controls resources but not passage.
Does it handle disputed territories?
Disputed areas are drawn according to a single dataset convention. Do not rely on the result for any legal or political position.
How does this differ from the what country am I in tool?
This tool takes typed coordinates; the other starts from your device location. Both use the same country data.
Can I look up a ship or aircraft position?
Yes, but over water or at altitude the answer follows the point on the surface below.
What is the format of the country name?
It uses the common English short name (for example "United States" or "South Korea"), which can differ from the official long name used in treaties or by the country itself.
