The 575 area code serves southern and eastern New Mexico – essentially the entire state outside the Albuquerque-Santa Fe corridor. Created in 2007 when it split from 505, 575 covers a vast region from Las Cruces in the south to Taos in the north and Hobbs on the Texas border.
Quick Summary of the 575 Area Code
| Area Code | 575 |
| State | New Mexico (NM) |
| Region | Southern & Eastern New Mexico (Las Cruces, Roswell & Taos) |

Geographic Coverage
The 575 area code covers southern and eastern New Mexico, including Las Cruces in the south near El Paso, Roswell and Clovis in the east, the Permian Basin oil cities of Carlsbad and Hobbs in the southeast, Alamogordo near White Sands, Silver City in the southwest, and the art colony of Taos in the north. It wraps around the central 505 region on three sides and borders Texas, Arizona, Colorado, and Mexico.
Time Zone
The 575 area code observes Mountain Time (MT). Clocks follow Mountain Standard Time (UTC−7) in winter and shift to Mountain Daylight Time (UTC−6) from mid-March through early November. All of New Mexico observes Mountain Time and, unlike neighboring Arizona, does change its clocks for daylight saving. From the West Coast, this region is one hour ahead of Pacific Time, so a 9:00 AM call in California reaches a 575 number at 10:00 AM local time.
Tip: Business hours across the 575 region generally run 9:00 AM to 5:00 PM Mountain Time, Monday through Friday.
How to Dial a 575 Number
Area code 575 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 (575 + the line number) always works reliably. For international callers, dial your country’s exit code, then +1 (the North American country code), then 575, followed by the seven-digit local number.
Scam Alerts for the 575 Area Code
Like every U.S. area code, 575 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Las Cruces, Roswell, Clovis, Hobbs, Carlsbad, Alamogordo, Silver City, Taos should stay alert to the following common tactics:
| Scam Type | What to Watch For |
|---|---|
| IRS / Tax Scams | Callers impersonating the IRS and threatening arrest over supposed unpaid taxes. |
| Utility Shut-off | Fake El Paso Electric or Xcel Energy callers demanding instant payment to keep your power on. |
| Oilfield Job Scam | Fake Permian Basin oilfield job offers seeking personal data or upfront “equipment” fees. |
| Student Loan Scam | Calls offering fake loan forgiveness to New Mexico State University students for a fee. |
If you receive a suspicious call from a 575 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 New Mexico 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 (PNM or El Paso Electric) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 575 caller making such a demand is a scammer.
