PAV-IGlobal Postal Address Verification

PAV-I is an international postal address verification API which validates and standardizes addresses for over 240 countries. Businesses can ensure data quality for their international customer base and gain global customer contact information efficiently at point of entry.

There is no prior knowledge of international address formats required. PAV-I takes the guesswork out of the many international address formats and foreign characters that exist worldwide.
