Croatia VAT number: format and validation

By Remco from Avatcado

Format

HR followed by 11 digits. The local term is PDV identifikacijski broj (PDV ID broj, Croatian).

Pattern: /^\d{11}$/

  • The 11 digits are the holder's OIB (osobni identifikacijski broj), Croatia's universal person and company identifier used for all taxes
  • The VAT ID is simply HR plus the OIB, but it is only active once the holder is VAT-registered with Porezna uprava

Example of a registered number: HR81793146560

Check digit

Croatia VAT numbers carry a check digit (ISO 7064 MOD 11,10): The final digit is an ISO 7064 MOD 11,10 check computed over the first ten digits.
