Despite North Carolina's growth in the second half of the 20th century, this configuration remained in place for 39 years.
BellSouth drew the new 919-910 boundary in order to preserve seven-digit dialing throughout Mebane.
In 1998, 919 was cut back to its present size when the northeastern portion, including Rocky Mount, Greenville and New Bern, was split off to form area code 252.

Projections in 2019 have no exhaust date for 919/984, meaning that the Triangle will not need another area code for at least 30 years.
