Mailing & Fulfillment — ‘Move Update’ Moves Forward

99 Percent Accuracy

The USPS has developed a process for those customers who proclaim their lists are accurate and up-to-date. The 99 Percent Test is a computer-based process that performs USPS ZIP+4 coding and change of address processing utilizing the customer's file as input.

The test can be accomplished by submitting the files directly to the USPS for processing, or the USPS can bring the 99 percent process onsite for your customers to process the files.
