  1. New Postal Code Object in GET /v1/countries Each country object in the response now includes a postal_code object with two fields:
    • required — boolean indicating whether a postal code is mandatory for that country
    • regex — validation pattern for the expected postal code format; null for countries where postal codes are not applicable

  1. Postal Code Validation on Submission Address fields that include a postal code are now validated against the regex pattern of the specified country at the time of submission. Invalid formats are rejected with a descriptive error, reducing the likelihood of triggering a Request for Information (RFI) due to malformed address data.
