The 458 area code is an overlay serving central, eastern, and southern Oregon, including Eugene, Bend, and Medford. Introduced in 2010, it was layered directly on top of the established 541 area code to supply fresh phone numbers across the largest region of the state.
Quick Summary of the 458 Area Code
| Area Code | 458 |
| State | Oregon (OR) |
| Region | Central, Eastern & Southern Oregon (Eugene, Bend & Medford) |
| Major Cities | Eugene, Bend, Medford, Springfield, Corvallis, Roseburg, Klamath Falls, Ontario |
| Time Zone | Mostly Pacific (PT); far-east Malheur County Mountain (MT) |
| Dialing Format | 10-digit dialing required |
Geographic Coverage
The 458 area code shares an identical footprint with 541, covering 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. Because it is an overlay rather than a separate region, a 458 number and a 541 number can exist on the same street.
Time Zone
Most of the 458 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 458 region generally run 9:00 AM to 5:00 PM local time, Monday through Friday.
How to Dial a 458 Number
Because area code 458 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 (458 + 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 458, followed by the seven-digit local number.
Scam Alerts for the 458 Area Code
Like every U.S. area code, 458 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 | Threatening calls demanding immediate tax payment via gift cards or wire transfer. |
| Utility Shut-off | Impostors claiming to be Pacific Power threatening to cut power unless you pay now. |
| Vacation Rental Scam | Fraudulent Bend or Rogue Valley vacation rental listings that vanish after you pay a deposit. |
| Tech Support Fraud | Pop-ups or calls claiming your computer is infected and asking for remote access. |
If you receive a suspicious call from a 458 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 (Pacific Power or Portland General Electric) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 458 caller making such a demand is a scammer.
History and Economy of the 458 Region
n
The 458 area code entered service in 2010 as an overlay for the entire 541 region. Overlays let regulators add a fresh supply of phone numbers to a crowded area without forcing existing customers to change their established numbers, so 458 covers precisely the same cities as 541. The regional economy is diverse: the University of Oregon and wood products in Eugene, Oregon State University and Hewlett-Packard in Corvallis, and the booming outdoor-recreation, tourism, and brewing economy of Bend, one of the fastest-growing cities in the country. 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. Because 458 is the newer of the two codes, it appears most often on recently activated mobile numbers and new business lines.

Looking Up a 458 Number
n
To identify a 458 caller, use a reverse phone lookup or search the complete 10-digit number online. Because 458 is a newer code often used for mobile numbers, some callers may have a smaller public footprint, so never share personal or financial details with an unverified caller.
