Address Validation

Address verification is a system to check out the mailing address of people. The companies that offer address validation service compare the address against the authoritative database to find out whether the address is valid or not. This entire process is known as address verification.

If the concerned address does not match with the address filed in the authoritative database, then the system proclaims it invalid. That indicates that the concerned address either does not exist or is not registered in the database.
