Mail Stop Code

This Mail Stop Code (MSC) Listing for the National Institutes of Health (NIH) is provided as a source of information and is not intended to be used as an employee directory. It identifies established mail stops in buildings based on the needs of Institutes and Centers (IC); number of employees assigned; location of occupied space and of course, mail volume.

The use of the MSC listing facilitates efficient sortation and delivery of mail and interoffice correspondence within NIH. The information provided in this listing such as the MSC, points of contacts (POC), Mail Managers, ICs and telephone numbers are subject to frequent changes.
