To make a DSN phone call, users will continue to dial “94” but then dial the phone number with a three-digit prefix. The three digit prefix is based on location and can also be found with the individual’s information in the global address list. The three-digit prefix for Wright-Patterson AFB is “312.”
Other location three-digit prefixes are as follows:
• Continental United States (CONUS) and Puerto Rico: 312, 313, 322, 323, 392
• Europe: 314, 324
• Pacific: 315, 325
• Alaska: 317, 327
• Central Command (Southwest Asia): 318, 328
• Canada: 319, 329
