Area codes serving Oklahoma City
Oklahoma City sits in Oklahoma, part of the South region and the Central Time zone. Its numbers are spread across an overlay of 2 codes that all cover the same ground: 405, 572.
The original code is 405. As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.
How to pick an area code for a new number
When you activate a new line in Oklahoma City, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 405), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.
Dialing in Oklahoma City
Because Oklahoma City is an overlay area, 10-digit dialing is mandatory: always dial the area code plus the seven-digit number, even for a neighbor. See 10-digit dialing and overlay area codes for the background. For every code in Oklahoma, visit the Oklahoma area codes page.
