PostalDataPI Integrations

Validate up to 1,000 postal codes in one request. Mixed countries supported. Same flat per-record price as the single Validate action — no bulk discount or premium. Ideal for list cleanup and CRM data hygiene.

Look up city, state, and coordinates for a postal code. Works for ZIP codes (US), postcodes (UK), PLZ (Germany), CEPs (Brazil), and 240+ countries and territories.

Check whether a single postal code exists in a country. Returns a boolean — for full city/region details use Lookup Postal Code instead. For batch checks use Bulk Validate.

Get full metadata for a postal code, including coordinates and country-specific fields. For US: state, county, timezone. For non-US: whatever the data source provides (province, prefecture, municipality, …).

Find all postal codes for a given city. For US searches, provide a state (name or 2-letter abbreviation). For other countries, state is optional.
