ACS is a post mailing service that allows mailers to receive change-of-address (COA) and other reasons for non-delivery electronically and reduce the number of manual (hardcopy) address notifications.
Who is ACS for?
First Class Mail
ACS™ has many benefits over manual address corrections.
ACS is a cost-effective, efficient means of obtaining accurate COA or reasons for non-delivery information. Utilizing ACS can:
- Reduce manual address costs.
- Reduce labor-intensive address change functions by eliminating returned mail.
- Retrieve address change information electronically via a secure Internet site to allow automated updating of mailing lists.
- Receive notifications that relate specifically to their address files.
ACS has four distinct implementation methods which offer several different options:
- OneCode ACS Technical Guide contains information to participate in OneCode ACS® (uses IM® barcode).
- Traditional ACS Technical Guide contains information to participate in Traditional ACS™.
- Full-Service ACS, which is currently provided as an additional benefit for mail that qualifies for Full-Service discount postage prices (uses IM® barcode).
- IMpb ACS Technical Guide contains information to participate in IMpb® ACS (uses IM® package barcode).
For a complete overview of Address Change Services including eligibility, benefits, implementation, and technical specifications please review the ACS™ Product Information Guide: Publication 8
To participate in ACS™, mailers must modify their mailing label, address block, and mailpiece according to the requirements associated with the specific ACS service they are applying for.
As ACS-modified mailpieces are processed via Postal Automation Redirection System (PARS) or Computerized Forwarding System (CFS), ACS notifications are generated when possible. However, ACS is an enhancement to the traditional process of manual (hard copy) notifications and it does not completely replace or eliminate hard copy address change notifications.
The ACS notifications are transmitted to the National Customer Support Center (NCSC), where the notifications are consolidated into a file for the mailer. ACS fulfillment options vary depending on the specific ACS service you are applying for.
If you have not already opened an ACS account, contact the ACS Department at firstname.lastname@example.org. Check, credit card, ACH credit or CAPS payment options are available.
