Find US ZIP references near coordinates
Enter latitude and longitude to find nearby US postal reference points within 50 km, compare distances and cities, and open ZIP details.
A nearby reference is not your postal code
The snapshot provides reference coordinates, not postal boundary polygons. Geolib calculates distances to reference points; the nearest 20 within 50 km are shown. Several ZIP codes can share coordinates, and the closest point does not establish your address’s ZIP. Empty results do not trigger an inferred ZIP or a wider search.
Explicit location and privacy
You can enter coordinates manually. Browser location requests permission only after a click and displays the reported accuracy radius. Coordinates stay in page memory; they are not saved in collections or share links or sent to this site’s location API. The browser or operating system may use its own location service. Denying permission leaves manual search available.
City search and IP lookup
When you know the city, search with its state to distinguish namesakes. The IP page links to city ZIP candidates only when a US state and city are available. A network exit location is approximate and cannot establish a residential address or a specific ZIP.
Export and continue generating
Exports include reference ZIPs, cities, states, source coordinates and version, not your input coordinates. ZIP codes remain five-character strings, including leading zeros. Open a result to use the existing ZIP detail tool, view its source and map, and generate a matching synthetic address.
