Is the number part of the name of the stateOrProvince or is it a postalCode? I know in Dublin there were numbered "postal districts" prior to the implementation of Eircode, but the city and county are both "Dublin" not "Dublin 8" or such. > Red Hat Czech s.r.o., Purkyňova 99/71, 612 45, Brno, Czech Republic Am I parsing this correctly as follows? Company: Red Hat Czech s.r.o. Street Address: Purkyňova 99/71 Postal Code: 612 45 City: Brno Country: Czech Republic Does this imply that addresses in the Czech Republic do not use a state or province?
