You can explore all our address validation solutions in one place, including the Master address list, Address validation service, International address verification, USPS address verification tool, Bulk address validation, and Address autocomplete.

In Romania, a valid address must match the country’s postal formatting rules. Verify that the postal code (Cod poștal) follows the 999999 format; it appears before city; the street name comes before the house number. Include the Thoroughfare type (strada, aleea, etc.) where applicable. The standard Romanian address structure is: Thoroughfare type, Thoroughfare name, Number, Sub-building info, Sector.

Romania uses the postal code format 999999. Locally, postal codes are referred to as “Cod poștal.” The postal code structure is 6 digits: postal regions + district/region + delivery area. Example address: Strada Locotenent Petre Linteș 32, 050871 București. Postal codes are administered by Poșta Română.

A properly formatted Romanian address follows this structure: Thoroughfare type, Thoroughfare name, Number, Sub-building info, Sector. In Romania, the street name precedes the house number, and the postal code is placed before city. A distinctive address element is the Thoroughfare type (strada, aleea, etc.). Example: Strada Locotenent Petre Linteș 32, 050871 București.

Address validation checks format and completeness — whether an address is properly structured and meets postal standards. Address verification goes further by confirming the address exists and is linked to a real recipient. For example, validating a Romanian address means checking that the postal code (Cod poștal) follows the 999999 format and appears before city. Verifying it means confirming that a real recipient lives or operates at that specific address. Most businesses benefit from both: validation broadly for data quality, and verification for higher-risk situations like compliance or fraud prevention.
