UN/LOCODE database: 2026 update
We've updated our UN/LOCODE database to reflect the 2026 UNECE release.
More than 88% of UN/LOCODE entries are now directly matched to our postal and address databases, while country codes, IATA codes, and coordinates have been reviewed and updated across 116,086 entries.
You can rely on up-to-date UN/LOCODE data, fully synchronized with the latest official publication and enriched with GeoPostcodes' location databases.
Reach out to your Customer Success Manager to learn more.
New Table-based Address Formats documentation
The Address Formats documentation is now available in a table-based format, making country-specific rules easier to implement.
Easily identify the fields required for complete address validation, how to identify the city, and the country-specific rules that affect major cities.
Whether you're building address forms or setting up validation workflows, the new format makes it faster to apply the right rules for each country.
Email your Customer Success Manager to receive a copy of the documentation.

Welcome to Square City: where streets have no names
Did you know there's a German city where addresses work like a chessboard?
In the centre of Mannheim, streets have no names. The old town is laid out as a grid of "quadrants," and each address is just a letter and a number — D4, E7, C6 — marking the block and the building within it.
Locals navigate it easily; the city even earned the nickname Quadratestadt, "Square City."
Mannheim isn't alone: most streets in Japan have no names either, with addresses built instead from nested districts and block numbers.
It's a useful reminder that "address" doesn't mean the same thing everywhere. Any system handling addresses at a global scale has to account for the ones that don't fit the street-name-and-number model.
