Estonia Postal Code API

About Estonia postal codes

Estonia uses 5-digit postal codes (sihtnumber). The first two digits indicate the county: 10-15 for Tallinn (Harju), 50-51 for Tartu. Estonia's digital-first governance makes postal code integration particularly relevant for e-residency and cross-border applications.
