On the Move

The National Customer Support Center (NCSC) is moving its office location. Starting Dec. 1, the new address for the NCSC will be:

NATIONAL CUSTOMER SUPPORT CENTER
UNITED STATES POSTAL SERVICE
225 N HUMPHREYS BLVD STE 501
MEMPHIS TN 38188-1001

The NCSC works closely with the mailing industry, vendors and internal postal customers to improve address quality. The USPS headquarters office of Address Management also is located at the NCSC.

Numerous USPS publications, forms, brochures, etc. currently provide the existing address for the NCSC – all of which will need to be updated, including those on usps.com and other postal websites. Telephone numbers for all NCSC personnel and program support groups will remain the same.
