Area code 710
|This article does not cite any references or sources. (December 2009)|
Area code 710 is a special area code, reserved to the federal government of the United States created in 1983. As of December 2006, it had only one working number, 710-NCS-GETS (710-627-4387), which requires a special access code to use. See Government Emergency Telecommunications Service for more information on this service.
Prior usage of 710
The 710 area code (along with area codes 510, 610, 810, and 910) was used prior to 1981 by AT&T for their TWX, or TeletypeWriter eXchange, network. The area code was decommissioned for TWX usage in 1981 when Western Union, which had acquired the TWX network in 1969 from AT&T and renamed it Telex II, upgraded the network to "4-row" ASCII operation (it previously used both "3-row" Baudot and ASCII transmission).
Current usage of 710
There is currently only one known working phone number in this area code. A special access code of 12 digits is required for using the service. Upon dialing this phone number, the caller hears a mechanical beep which prompts the caller to enter the area code. If a correct code is entered, they are prompted to dial the destination number (area code + number). If an access code is not entered at the beep, the call is then redirected to a live human operator who then asks for the access code.
