The Second Quarter 2025 International Postal Database contains updated country data. For a complete list of countries and the level at which the database recognizes countries, see Country Levels.

Note: Although the Second Quarter 2025 database is compatible with the previous CODE-1 Plus International 1.8.4 software versions, it is highly recommended that you install the CODE-1 Plus International 1.8.5 software to benefit from the enhancements included in the 1.8.5 release. The CODE-1 Plus International 1.8.5 software release contains enhancements that improve address matching for all countries. For information about installing the Second Quarter 2025 International Postal Database, see the installation instructions for your respective platform.
