Area code 910
Area code 910 was established on November 14, 1993 as a split from area code 919, as North Carolina's first new area code in 39 years. Originally, it covered a fan-shaped region in the southeastern and western north-central portions of the state. The two parts were only connected by a tendril in the Sandhills. However, while southeastern North Carolina was not large enough at the time for its own area code, it was too large to stay in 919.
Prior usage for TWX
Area code 910 was originally designated for one of three US regional numbering plan areas for the former AT&T TWX (TeletypeWriter eXchange) network, sold to Western Union in 1969 and renamed as Telex II. It covered every US point west of the Mississippi River.
The original TWX area codes were 510 in the US and 610 in Canada. The addition of 710 in the Northeast (New England, NY, NJ, PA, MD, DC, VA, and WV), 810 in MI OH IN and most of the South (NC, SC, GA, FL, LA, MS, FL, AL, and KY) and 910 west of the Mississippi allowed each major city one or more local exchange prefixes in the special numbering plan area. The service operated at 110 bit per second transmission rates on Bell 101 modems and mechanical teletypewriters.
The special US TWX area codes (510, 710, 810, 910) were decommissioned in 1981; Canada moved its remaining 610-numbers to area code 600 in 1992.
