Area code 919 was established in 1954 and later split to form 910 (1993) and 252 (1998) as the region grew. To expand numbering capacity without changing existing phone numbers, the 984 overlay was introduced in 2011, and 10‑digit dialing is required for local calls. Both 919 and 984 phone numbers work across the same footprint, so residents and businesses in Cary share one seamless calling region. With a mix of research, education, and thriving suburbs, 919 is a widely recognized North Carolina area code.
