A Seamless Postcode Lookup Service for Global Coverage
Melissa’s postcode lookup service enables organisations to validate and interpret postcode data across a single country or in 240+ countries and territories worldwide — all from one interface. We handle the complexity of global postcode structures so you can reliably work with location data at scale.
When a postcode is submitted, our technology applies country-specific rules and reference data to accurately identify and validate the associated geographic area, returning structured outputs suitable for operational and analytical use.
- Standardised postcode data aligned to official postal authority formats.
- Structured location components such as locality, region and postal code fields.
Best-In-Class Postcode & Location Data Technology
Melissa’s postcode lookup and verification technology has been refined over more than 40 years, continuously evolving to incorporate country-specific rules and advanced validation logic. By leveraging official postal reference data from authorities such as Royal Mail PAF, Australia Post, and USPS, Melissa ensures postcode information remains accurate, up-to-date, and reliable across global markets.
Address datasets are updated as soon as changes are released by official sources, enabling organisations to confidently rely on trusted postcode data for logistics, analytics and location-based applications.
