Global Postal Code Reference

Lookup postal code formats for countries around the world. Each entry includes the format structure, a real example, and a regex validation pattern for use in your applications.

How this Global Postal Code Finder works

This geographical lookup service locates postal codes worldwide by accepting location names, addresses, or coordinate inputs and returning standardized postal/ZIP code identifiers along with administrative boundary information like city, state, and country details. The finder integrates mapping data enabling address validation, shipping calculations, or demographic analysis requiring granular location identification.

Users input search queries ranging from complete addresses through partial information (city names alone), select target countries from comprehensive databases, and receive postal code results with contextual geographical data. The system handles various international formats: US ZIP codes (5-digit or ZIP+4), UK postcodes (alphanumeric), Canadian postal codes (alternating letter-digit patterns), and nation-specific conventions across hundreds of countries. Validation features verify address completeness suggesting corrections for malformed inputs, geocoding capabilities convert postal codes into latitude/longitude coordinates enabling map plotting, and reverse lookup accepts coordinates returning corresponding postal codes for location-based applications.

Advanced functions support bulk processing uploading address lists and enriching with postal data, proximity searches finding nearby postal codes within specified radii, and administrative boundary queries listing all codes within cities or states for comprehensive coverage. Export formats produce structured data (CSV, JSON) compatible with CRM imports or database updates, API integration enables automated address standardization in e-commerce checkout flows, and mapping visualizations display postal code territories on interactive maps. Common applications include validating customer shipping addresses before order fulfillment, calculating delivery zones for logistics planning, standardizing contact databases for marketing segmentation, verifying address accuracy in user registrations, or conducting demographic analysis using postal code-level census data. Privacy considerations emphasize legitimate usage for business operations versus prohibited purposes like unwanted marketing or surveillance activities requiring informed consent.
