Area Code for Oklahoma City
Oklahoma City uses area codes 405 (1947 original) and 572 (2021 overlay). Full history, OKC metro coverage map, scam alerts, and how to get a local OKC number fast.
Oklahoma City runs on two area codes — 405 (the 1947 original) and 572 (the 2021 overlay) — making central Oklahoma one of the more recently updated dialing zones in the south-central United States.
Whether you’re decoding an incoming OKC call, choosing a local area code for your business, or tracing how the Sooner State’s phone geography evolved, this guide covers the full picture: history, metro coverage by neighborhood, the cultural weight of “The 405,” Oklahoma-specific scams, and how to get a business number in minutes.
What’s the area code for Oklahoma City?
Oklahoma City is served by two area codes, both covering the same central Oklahoma geography under the North American Numbering Plan (NANP):
| Code | Established | Type | Coverage | Notes |
|---|---|---|---|---|
| 405 | 1947 | Original | OKC metro + central OK | One of the original 86 NANP codes; most recognized OKC code |
| 572 | Jan 2021 | Overlay | Same as 405 | OCC-approved all-services overlay; 10-digit dialing required |
Both codes share the Central Time Zone (CT) — UTC−6 in winter, UTC−5 in summer.
A practical rule: a 405 number is an established OKC line, likely a business or long-tenured resident. A 572 number is a newer assignment from 2021 onward. Both are equally local, and either will build the same trust with an Oklahoma City audience.
Tulsa and northeastern Oklahoma use area code 918 — a separate region since 1953. Western and southern Oklahoma use area code 580 (since 1997).
OKC metro area codes by region
Unlike some metro areas where codes split by geography, 405 and 572 cover the same territory with no geographic boundary between them. Either code can appear anywhere in central Oklahoma.
Downtown OKC, Bricktown, and Midtown
Downtown Oklahoma City — including the Bricktown entertainment district and Midtown’s mixed-use corridor — is home to the densest concentration of 405 numbers. State government offices, Devon Energy’s 50-story tower, and the OKC Thunder’s Paycom Center all anchor the urban core.
Mesta Park and Nichols Hills
Nichols Hills and Mesta Park are OKC’s established residential and professional neighborhoods. These older suburbs carry a high density of long-tenured 405 lines — law firms, medical practices, and financial advisors that have held 405 numbers for decades.
Edmond
Edmond (~95,000) sits north of OKC and is home to the University of Central Oklahoma (UCO). It is one of the fastest-growing suburbs in the metro and is fully within the 405/572 overlay.
Norman
Norman (~130,000), south of OKC on I-35, hosts the University of Oklahoma (OU) — the state’s flagship research university. The OU football program is one of the most storied in college sports. All Norman numbers are 405/572.
Moore
Moore (~62,000) sits between OKC and Norman. It gained national attention after the May 2013 EF5 tornado. The city is fully within the 405/572 service area.
Mustang and Yukon
Mustang and Yukon sit west of OKC along I-40 — fast-growing bedroom communities that represent the metro’s westward expansion. Both carry 405/572 numbers.
Bethany and Warr Acres
These smaller communities on OKC’s western border are fully embedded in the 405/572 overlay. Bethany is home to Southern Nazarene University.
Midwest City and Del City
East of OKC, Midwest City (~58,000) borders Tinker Air Force Base — one of the largest Air Force logistics centers in the country. Del City sits adjacent. Both are 405/572 territory.
History of Oklahoma City area codes
Oklahoma City’s area code timeline is a compressed story of the state’s demographic and economic growth across seven decades.
1947 — 405 is born. AT&T engineers design the North American Numbering Plan (NANP) and assign area code 405 to the entire state of Oklahoma. It is one of the original 86 NPAs. Every Oklahoma phone — OKC, Tulsa, Lawton, Enid — shares a single code.
1953 (January 1) — 918 splits off northeastern Oklahoma. Population growth and the early spread of telephone lines strain 405’s supply. The fix: peel off Tulsa and northeastern Oklahoma. Area code 918 is activated. Oklahoma now has two codes — 405 for central and western OK, 918 for the northeast.
1997 (November 1) — 580 splits off western and southern Oklahoma. Further growth forces a second split. Area code 580 takes western and southern Oklahoma — Lawton, Enid, Ardmore, and the Panhandle. Area code 405 shrinks to central Oklahoma, anchored by OKC.
2017 — NANPA projects exhaustion. As of October 2017, the North American Numbering Plan Administrator projects that 405 will exhaust its available number blocks by the second quarter of 2021. The surge in mobile phones and VoIP lines accelerates number consumption far beyond what planners anticipated in 1947.
2020 (January 9) — 572 overlay announced. The Oklahoma Corporation Commission (OCC) — the state’s telecom regulator — approves an all-services overlay for the 405 region. Area code 572 is selected. The overlay approach avoids forcing existing 405 customers to change their numbers.
2021 (January) — 572 activates; 10-digit dialing becomes mandatory. Central Oklahoma moves to mandatory 10-digit dialing for all local calls. New lines are assigned 572. Oklahoma City joins the list of US metros where two codes ring simultaneously in the same neighborhoods.

405 as OKC identity
Area code 405 carries cultural weight that extends well beyond a phone prefix.
“The 405” is shorthand for OKC itself. Local brands, clothing lines, and music artists use “405” the way New Yorkers use “212.” It appears on murals, T-shirts, and event branding across Bricktown and Midtown. For Oklahomans, 405 signals authenticity — it marks someone who was there before the city’s recent growth boom.
OKC Thunder (NBA). The Oklahoma City Thunder — relocated from Seattle in 2008 — became the fastest-adopted sports franchise in recent NBA history. Kevin Durant, Russell Westbrook, and later Shai Gilgeous-Alexander built a national following around a 405 area code. Thunder basketball is inseparable from OKC identity.
Oklahoma Sooners football. The University of Oklahoma in Norman (405) is one of the most decorated programs in college football history. OU’s move to the SEC in 2024 brought national attention back to the 405 corridor. On game days, the entire metro runs on 405.
Oklahoma City National Memorial. The Alfred P. Murrah Federal Building bombing on April 19, 1995 killed 168 people and remains the deadliest domestic terrorist attack on US soil before 9/11. The Oklahoma City National Memorial and Museum at the site has become one of the most visited memorials in the country. For many Americans, 405 is permanently linked to that act of resilience.
Bricktown entertainment district. The Bricktown Canal and its surrounding restaurants, music venues, and the Chickasaw Ballpark (home of the Oklahoma City Dodgers, Triple-A) transformed a former warehouse district into the city’s entertainment core. Bricktown is the face of OKC’s 21st-century revival.
Oil and energy capital. Oklahoma City sits atop the Anadarko Basin, one of the most productive natural gas fields in North America. Devon Energy, Continental Resources, Chesapeake Energy, and OGE Energy are all headquartered here — making the 405 corridor one of the most energy-dense area codes in the United States.
State government hub. Oklahoma City is the state capital. Every state agency, the Governor’s office, and the Oklahoma Supreme Court operate on 405 numbers — adding a layer of civic authority to the code.
OKC area code spam and scams
Oklahoma City area codes are actively spoofed. Central Oklahoma-specific patterns include:
OG&E utility shutoff impersonation. Oklahoma Gas and Electric (OG&E) has formally warned customers about scammers posing as utility representatives, threatening immediate power shutoff unless payment is made by phone. OG&E never demands instant phone payment. Verify your account at OGE.com/PaymentOptions directly if in doubt.
IRS arrest threats. Midwest City PD and other OKC-area agencies have documented a persistent pattern of IRS impersonators calling 405 and 572 numbers, threatening arrest for unpaid taxes. The IRS does not make cold calls or demand phone payments.
Fake tornado-recovery contractors. After severe weather events — and Oklahoma averages more tornadoes per square mile than any other state — scammers contact affected households posing as FEMA representatives or licensed contractors. They request upfront cash payment for repairs that never happen.
Unclaimed property fraud. The Oklahoma State Treasurer’s Office has issued formal warnings about callers impersonating the treasurer’s office, claiming to release unclaimed property funds in exchange for personal information or a processing fee.
STIR/SHAKEN and business trust. The FCC mandates that carriers implement STIR/SHAKEN — a caller authentication framework that assigns each outbound call an attestation level. A-attestation means the carrier fully verified the calling party owns the number. B-attestation is partial. C-attestation is unverified — typical of spoofed scam calls.
Spoofed scam calls receive C-attestation and display as “Spam Likely” on modern smartphones. When you get an OKC number through DialPhone, outbound calls carry A-attestation — so your business calls reach customers as verified, not screened.

How to get an Oklahoma City business phone number
Getting a 405 or 572 number for your business takes under 10 minutes through a cloud VoIP provider. No Oklahoma office required.
Step 1: Choose your area code. Both 405 and 572 carry equal local credibility in OKC. If 405 specifically matters to your brand — for the cultural cachet of the original code — check availability first, as 405 inventory is more limited.
Step 2: Sign up with DialPhone. Search available OKC numbers by area code during signup at DialPhone pricing. Filter by 405 or 572 depending on preference and availability.
Step 3: Assign the number to your team. Route the OKC number to your mobile, desktop app, or a shared team queue. Add a voicemail greeting, call menu, or AI receptionist as needed.
Step 4: Set outbound caller ID. Configure your 405 or 572 number as the outbound caller ID so calls you make display the local number — not an 800 number or your personal cell.
Step 5: Port existing numbers if needed. Already have an OKC number with another carrier? Bring it to DialPhone through number porting. US local number ports typically complete in 2–5 business days.

OKC area code FAQ
Oklahoma City area code FAQ
What is the area code for Oklahoma City?
Oklahoma City uses two area codes: 405 and 572. Area code 405 is the original, assigned in 1947 as one of AT&T's first 86 North American Numbering Plan codes. It covered all of Oklahoma until northeastern Oklahoma split off as 918 in 1953.
Area code 572 was added in January 2021 as an all-services overlay after the Oklahoma Corporation Commission projected 405 would exhaust by mid-2021. Both codes cover the same central Oklahoma geography — including Edmond, Norman, Moore, Yukon, and Mustang — and 10-digit dialing is now mandatory for all local calls.
Is 572 the same area as 405?
Yes. Area code 572 is a full overlay of 405, covering the identical geographic territory. There is no split — a 572 number is just as local as a 405 number, and both serve the same Oklahoma City metro communities.
New phone lines assigned after January 2021 often receive 572. Existing 405 holders keep their numbers permanently. The overlay approach was chosen specifically to avoid forcing businesses and residents to change established numbers.
What cities are in the 405 area code?
Area code 405 (and its 572 overlay) serves central Oklahoma. Major cities include Oklahoma City (~700,000), Norman (~130,000, home of OU), Edmond (~95,000, home of UCO), Moore (~62,000), Midwest City (~58,000), Del City, Yukon, Mustang, Bethany, Warr Acres, The Village, Nichols Hills, El Reno, Guthrie, Shawnee, Stillwater, and Chickasha.
The coverage spans roughly 19 counties — a large geographic footprint anchored by the state capital at its center.
When did Oklahoma City get the 572 area code?
The 572 overlay was formally announced on January 9, 2020. The Oklahoma Corporation Commission (OCC) had approved an all-services overlay after the North American Numbering Plan Administrator (NANPA) projected that 405 would exhaust its number supply by Q2 2021.
Mandatory 10-digit dialing for all central Oklahoma local calls began in January 2021, and new 572 assignments followed. Existing 405 customers were not required to change their numbers.
What time zone is the 405 area code?
Area codes 405 and 572 are both in the Central Time Zone (CT). Central Standard Time (CST) is UTC−6; Central Daylight Time (CDT) is UTC−5. Oklahoma observes daylight saving time, switching on the second Sunday in March and reverting on the first Sunday in November.
For business callers: OKC is 1 hour behind New York (ET), same as Chicago (CT), and 2 hours ahead of Los Angeles (PT).
Are calls from 405 numbers spam?
Not inherently. Thousands of legitimate Oklahoma City businesses use 405 numbers every day. The issue is spoofing — scammers fake a local OKC caller ID to boost answer rates.
Common 405 scam patterns include OG&E utility shutoff threats, IRS arrest impersonation, fake tornado-recovery contractors, and unclaimed property fraud. STIR/SHAKEN (FCC-mandated caller authentication) assigns A, B, or C attestation to calls. Spoofed calls typically get C-attestation and appear as 'Spam Likely.' A 405 or 572 number through DialPhone carries A-attestation — the highest trust level.
Can I get an Oklahoma City 405 or 572 number without an OKC office?
Yes. Virtual (VoIP) phone numbers are not tied to a physical location. Any business can get a 405 or 572 number through a cloud phone provider and route calls to any device — mobile, desktop, or a shared team queue.
DialPhone assigns available OKC numbers in minutes. No Oklahoma office required, no hardware, no long-term contract. Outbound calls display your 405 or 572 number as caller ID. If you already have an OKC number with another carrier, number porting to DialPhone typically completes in 2–5 business days.
What is the difference between 405 and 918 in Oklahoma?
Area code 405 covers central Oklahoma, anchored by Oklahoma City. Area code 918 covers northeastern Oklahoma, anchored by Tulsa — Oklahoma's second-largest city.
The split happened on January 1, 1953, when AT&T carved 918 out of the original statewide 405 code. Western and southern Oklahoma later became area code 580 in 1997. Today, 405/572 (OKC), 918 (Tulsa), and 580 (western/southern OK) together cover the entire state.
