The 580 area code serves western and southern Oklahoma, including Lawton, Enid, and Ardmore. Created in 1997 when it split from 405, 580 covers the largest geographic region in the state, a wide sweep of plains, farmland, and small cities outside the two big metros.

Geographic Coverage
The 580 area code covers western and southern Oklahoma, including Lawton in the southwest near Fort Sill, Enid and Ponca City in the north-central grain belt, Ardmore and Duncan in the south near the Texas line, and Woodward, Altus, and Elk City across the western plains. It borders Texas, Kansas, and the Oklahoma Panhandle.
Time Zone
The 580 area code observes Central Time (CT). Clocks follow Central Standard Time (UTC−6) in winter and shift to Central Daylight Time (UTC−5) from mid-March through early November. All of Oklahoma is on Central Time. From the West Coast, this region is two hours ahead of Pacific Time, so a 9:00 AM call in California reaches a 580 number at 11:00 AM local time.
Tip: Business hours across the 580 region generally run 9:00 AM to 5:00 PM Central Time, Monday through Friday.
How to Dial a 580 Number
Area code 580 is not part of an overlay, so it has traditionally allowed 7-digit local dialing. However, 10-digit dialing is now the recommended nationwide standard, and dialing the full 10-digit number (580 + the line number) always works reliably. For international callers, dial your country’s exit code, then +1 (the North American country code), then 580, followed by the seven-digit local number.
Scam Alerts for the 580 Area Code
Like every U.S. area code, 580 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Lawton, Enid, Ardmore, Duncan, Ponca City, Woodward, Altus, Elk City should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Callers claiming you owe back taxes and threatening arrest unless you pay immediately. |
| Utility Shut-off | Fake OG&E callers demanding instant payment to keep your power on. |
| Military / Veteran Scam | Calls targeting Fort Sill families with fake benefit or charity solicitations. |
| Farm / Equipment Scam | Fraudulent online listings for tractors or farm equipment aimed at rural buyers. |
If you receive a suspicious call from a 580 number, take these steps to protect yourself:
- Do not share personal information such as Social Security numbers, bank details, or passwords over the phone.
- Hang up and verify by calling the organization back using an official number from its website.
- Report the call to the FTC at reportfraud.ftc.gov and to the Oklahoma Attorney General’s Office.
- Block the number and consider registering with the National Do Not Call Registry.
Red Flag: Legitimate agencies such as the IRS, Social Security Administration, or your local utility company (OG&E or PSO) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 580 caller making such a demand is a scammer.
History and Economy of the 580 Region
n
Area code 580 was created in 1997, split from 405, to serve western and southern Oklahoma. The regional economy is anchored by agriculture, energy, and the military. Lawton is home to Fort Sill, a major U.S. Army post and the center of Army field artillery, along with a Goodyear tire plant, while Enid is a hub for wheat farming and grain storage and hosts Vance Air Force Base, a pilot-training installation. Ponca City has a long oil-refining heritage, Duncan is the birthplace of the oilfield-services company Halliburton, and wind energy has become a fast-growing industry across the windswept western plains, alongside cattle ranching and wheat production.
