The DSN Telephone Directory is provided solely as an aid to finding individual DSN site numbers; it is not a complete directory like a local phone book, nor are there plans to develop such a comprehensive resource. However, where possible we have provided hyperlinks, embedded into the site name, to provide further information for that specific base.
The DSN Telephone Directory is presented as a single global directory as well as divided into eight geographical subdirectories:
The entries in each subdirectory are in alphabetical order. There is one entry per site, based on the site's name, for example Andrews AFB or Fort Meade. A search tool will allow you to browse sites in order by alphabetic character.
The subdirectories can be printed through the links on this page's left menu bar. Download the complete DSN Telephone Directory.
Contact DSN to include your organization in the directory, or to notify us of any changes.
