ISO vs. USPS codes

Created:   |   Updated:

ISO 3166-1 alpha codes are defined by the International Organization for Standardization (ISO). They represent countries, dependent territories, and special areas of geographical interest. 

When shipping internationally via the United States Postal Service (USPS), you will need to use the USPS postal abbreviation for countries. However, you may find that international customers provide the ISO code instead. 

Use this guide to update international addresses with the USPS recognized abbreviation.

  • Use your browser's "Find" tool to locate codes/abbreviations quickly. 
    CTRL+F (for Windows) or COMMAND+F (for Mac)
  • <> in the equivalent column indicates that the ISO code differs from the USPS abbreviation.
  • = in the equivalent column indicates that the ISO code is the same as the USPS abbreviation.
  •  indicates that the country is a US territory. USPS considers the destination domestic. When addressing shipments to territories, the Country should be designated as United States, and the State field will indicate the Territory.
