Geocoding

Convert addresses to coordinates and back again.

10 tools

Choose address search for your users and region

Forward geocoding finds a location from text; reverse geocoding finds a place or address near coordinates. Autocomplete adds another requirement: useful suggestions while a user types. Evaluate these separately with local addresses, languages, abbreviations and incomplete input from your application.

OpenStreetMap address lookup

Nominatim offers search and reverse geocoding over OpenStreetMap data. Distinguish running the software yourself from calling the public service: the public endpoint has a usage policy and does not permit client-side autocomplete.

Search and autocomplete

Pelias supports search, autocomplete and reverse geocoding using multiple data sources. A self-hosted deployment also needs an import pipeline, storage and an update process; test that operational work as part of your prototype.

Managed location APIs

Compare hosted options when you need a provider to operate the service. For HERE or another vendor, verify coverage using your own address sample and check storage, attribution and display conditions for the intended use.

Before you choose

  • Score results against a labelled sample from your actual service area.
  • Test incomplete queries, language variants and ambiguous place names.
  • Check permitted caching, expected request volume and failure handling.
