Beginning Nov. 30 offices at the Naval Air Systems Command’s St. Inigoes/Webster Field will have new telephone numbers.

Telephone numbers that had an 862 prefix and last four digits ranging between 6000 and 6999 and between 8000 and 8999 will be changed to a 995 prefix. The last four digits will remain the same. For example, 301-862-6000 will become 301-995-6000.

All other telephone numbers at the NAVAIR site will remain the same.

The change brings new flexibility to the site’s telephone system.
