Postal Address Validation Output Columns (RNVP)
RNVP (Relevé Normalisé de Vérification Postale) is the industry-standard name for the postal address validation and standardization process. When DQVerify processes an address, it applies RNVP — verifying, correcting, and standardizing addresses against postal authority databases. In DQVerify output files, RNVP columns carry the prefix DQE_.
Use this article if your file-based batch processing includes postal address validation and you need to understand the DQVerify address columns in your output file. Does not apply to real-time API responses.
