Z4INFO is designed to give the mailer additional information to improve quality of the mailing address. The Z4INFO product is part of the Address Quality products sold to software developers who may integrate it into current products and processes for customers (end users) who process address lists. Z4INFO integration with the address matching engines used by major mailers helps reduce the amount of undeliverable-as-addressed mail.

Z4INFO works in conjunction with the ZIP + 4® product to improve the quality of address matching by providing a code describing the acceptable format for the primary and secondary address information in a particular ZIP + 4 block face.
