About Serbia codes
Need Serbia (RS) for a checkout form, shipping zone, or backend validation? This page summarizes the ISO 3166-1 country codes and official subdivisions developers use with CountriesDB.
This guide lists 32 official ISO 3166-2 subdivisions for Serbia. These are the same codes CountriesDB serves through widgets and the Backend Data API.
