History

Area code 910 was established in 1993 in an area code split from area code 919, and was North Carolina's first new area code in 39 years. It served a fan-shaped region in the southeastern and north-central portions of the state, including the Piedmont Triad, the Sandhills, and the southeastern coast. The two parts were only connected by a tendril in the Sandhills. Within only three years, 910 was already on the brink of exhaustion due to rapid growth in the Triad, Wilmington and Fayetteville, as well as the proliferation of cell phones and pagers. On December 15, 1997, area code 336 was created for the Triad and most of the old 910 territory's western portion. Normally, when an area code is split, the more populated portion keeps the old area code–in this case, the Triad. However, it was decided to let the southeastern portion of the state keep 910. Area code 910 has telephone numbers assigned for the central office code 988. ''988'' has been designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which creates a conflict for exchanges that permit seven-digit dialing. This area code was therefore required to transition to
