Before Activation

1. Submit a sample galley of 25 to 50 mailing labels or address blocks that have been modified to reflect the proper ACS coding. We will verify that all ACS information is placed correctly. If you are using the keyline option, each sample label must have a different keyline so that we may verify your check digit calculation and placement.

2. Submit at least one complete sample of your actual mailpiece. We will verify that your mailpiece and endorsement are acceptable for ACS processing.

3. Upon receipt of your samples, we will notify you in writing of their acceptance or advise you of any necessary corrections. To expedite activation, you may request your code(s) to be activated upon approval of samples.

4. After final approval, you must request activation of your participant code(s) at least 7 working days before your first ACS mailing. Submit requests in writing to the ACS Department. Failure to request activation prior to mailing will result in total elimination of any ACS electronic corrections, and all address corrections will be provided manually.

Note: Authorization and approval for Address Change Service may be given only by the National Customer Support Center in Memphis, TN.

It is important to note that the approval of ACS participant and keyline codes is for placement and content only. It does not imply the mailpiece meets any readability requirements. Mail piece readability must be approved by your local USPS mailpiece design specialist.
