USPS Modifications made to L601 Labeling Lists

June 11, 2024

Please be aware that effective June 5, 2024, modifications were made to the L601 Labeling Lists.

In the June 1st Labeling Lists release, the L601 was published with a duplicate 3-digit MXD record for every 3-digit NDC. Corrections have been made to remove the duplicate 3-digit MXD record from the L601 and to properly reflect only the 3-digit NDC in the L601.

If you have any questions or concerns, please contact labellist.ncsc@usps.gov.

As a new customer of Accuzip, I just wanted to thank you for all of Accuzip’s help and patience with us in preparing this job so well. Our particular thanks to your technicians for multiple support calls and emails with our elementary questions while we learned on-the-job. Frankly, none of us had any experience with postal regulations or mail list technology, so we are especially grateful to have had them as a resource. Please tell them how much we appreciate their help!
