MAC™ Batch Certification

MAC Batch is a software certification process designed in cooperation with the mailing industry to evaluate USPS^® manifest/presort mailing products manufactured by software developers. MAC Batch determines whether the manifest/presort mailing software accurately calculates postage for non-identical piece mailings submitted under the permit imprint payment method in accordance with standards published in the DMM^® reference manual and Publication 401, Guide to the Manifest Mailing System. MAC Batch is available only to software companies that develop manifest/presort products for resale or internal use. Participation is purely voluntary.

Use of MAC Batch certified software greatly reduces the occurrence of manifest/presort errors and increases the accuracy of postage payment. In doing so, the business mail acceptance process is streamlined and the efficiency of mail processing is improved. Although MAC Batch evaluates and certifies USPS manifest/presort mailing products, using MAC Batch certified software does not guarantee acceptance of mail. However, MAC Batch certified software does provide national approval of computer-generated manifest listings, postage statement facsimiles, and other USPS forms required for manifest mailings.
