USPS Introduces SingleSource ACS™

ACS™ is an online address correction service that allows mailers to receive change-of-address (COA) and other reasons for non-delivery electronically and reduces the number of manual (hardcopy) address notifications.

Coming in January 2013, SingleSource ACS™ removes the need to handle different ACS notice file formats when dealing with Full Service ACS™, OneCode ACS^®, and Traditional ACS™. With SingleSource ACS, all of the ACS notices are combined into a single file format and provided to mailers via Electronic Product Fulfillment (EPF).

SingleSource ACS can:

Provide ACS notices within 24 hours of receipt at USPS National Customer Service Center
Fulfill and provide monthly billing for non-Full Service qualified records
Include Full-Service, OneCode, and Traditional ACS in the OneCode ACS format in a single file
Provide a daily download from Electronic Product Fulfillment.

For more information, please refer to the new SingleSource ACS Technical Guide available on RIBBS at https://ribbs.usps.gov/acs
