The 541 area code serves central, eastern, and southern Oregon, including Eugene, Bend, and Medford. Created in 1995 when it split from 503, 541 covers by far the largest geographic region in the state – everything outside the Portland-Salem corner – and shares its footprint with the 458 overlay.
Quick Summary of the 541 Area Code
| Area Code | 541 |
| State | Oregon (OR) |
| Region | Central, Eastern & Southern Oregon (Eugene, Bend & Medford) |

Geographic Coverage
The 541 area code covers central, eastern, and southern Oregon, including Eugene and Springfield in the southern Willamette Valley, Corvallis to the north, Roseburg and Medford in the south, Bend in the central high desert, Klamath Falls near the California border, and Ontario in the far east on the Idaho line. It is the largest area code by land area in Oregon.
Time Zone
Most of the 541 area code observes Pacific Time (PT) – the same clock as Portland, Eugene, Bend, and Medford, following Pacific Standard Time (UTC−8) in winter and Pacific Daylight Time (UTC−7) in summer. However, the far-eastern corner of Oregon around Ontario in Malheur County observes Mountain Time (MT), one hour ahead, because that community is tied economically to the Boise, Idaho area. Both zones follow daylight saving time from mid-March through early November.
Tip: Business hours across the 541 region generally run 9:00 AM to 5:00 PM local time, Monday through Friday.
How to Dial a 541 Number
Because area code 541 operates as part of an overlay, 10-digit dialing is mandatory for every local and long-distance call. You must dial the full 10-digit number (541 + the seven-digit line number) even when calling a neighbor across the street. For international callers, dial your country’s exit code, then +1 (the North American country code), then 541, followed by the seven-digit local number.
Scam Alerts for the 541 Area Code
Like every U.S. area code, 541 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Eugene, Bend, Medford, Springfield, Corvallis, Roseburg, Klamath Falls, Ontario 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 Pacific Power callers demanding instant payment to keep your power on. |
| Vacation Rental Scam | Fraudulent Bend or Rogue Valley vacation rental listings that vanish after you pay a deposit. |
| Student Loan Scam | Calls offering fake loan forgiveness to University of Oregon and Oregon State students for a fee. |
If you receive a suspicious call from a 541 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 Oregon Department of Justice Consumer Protection.
- 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 (Portland General Electric or Pacific Power) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 541 caller making such a demand is a scammer.
History and Economy of the 541 Region
n
Area code 541 was created in 1995, split from 503, to serve the vast area of Oregon outside the Portland metro; as demand grew, the 458 overlay was added in 2010 across the same territory. The regional economy is diverse. Eugene is home to the University of Oregon and a wood-products heritage, Corvallis hosts Oregon State University and Hewlett-Packard, and Bend has become one of the fastest-growing cities in the country, powered by outdoor recreation, tourism, breweries, and a growing technology sector. The Rogue Valley around Medford is known for pears and the Harry & David company, while Klamath Falls and Ontario anchor agriculture in the south and east.

To identify a 541 caller, use a reverse phone lookup or search the full 10-digit number online.
