Address correction is utilized to reduce data entry errors and to help aid in the process of de-duping databases.
Corrected addresses are usually standardized before cross referencing the United States and Canadian Postal Address Database.
The address then goes through a series of checks and tests to make sure it is a valid address on file. An example address
correction process would involve changing a street to East from West to match the exact address on file and appending ZIP+4 to result in a 9-digit zip code.
