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.
