The 385 area code is an overlay serving the Wasatch Front of northern Utah, including Salt Lake City and Provo. Introduced in 2011, it was layered directly on top of the established 801 area code to supply fresh phone numbers across the most populous part of the state.
Quick Summary of the 385 Area Code
| Area Code | 385 |
| State | Utah (UT) |
| Region | Wasatch Front (Salt Lake City & Provo Metro) |
| Major Cities | Salt Lake City, West Valley City, Provo, Orem, Sandy, Ogden, Layton, West Jordan |
| Time Zone | Mountain Time (MT) – MST / MDT |
| Dialing Format | 10-digit dialing required |
Geographic Coverage
The 385 area code shares an identical footprint with 801, covering the Wasatch Front from Ogden and Layton in the north, through Salt Lake City and its suburbs of West Valley City, Sandy, and West Jordan, south to Provo and Orem. Because it is an overlay rather than a separate region, a 385 number and an 801 number can exist on the same street.
Time Zone
The 385 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 Utah 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 385 number at 10:00 AM local time.
Tip: Business hours across the 385 region generally run 9:00 AM to 5:00 PM Mountain Time, Monday through Friday.
How to Dial a 385 Number
Because area code 385 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 (385 + 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 385, followed by the seven-digit local number.
Scam Alerts for the 385 Area Code
Like every U.S. area code, 385 has been used by scammers who spoof local numbers to appear trustworthy. Residents in Salt Lake City, West Valley City, Provo, Orem, Sandy, Ogden, Layton, West Jordan 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 Rocky Mountain Power threatening to cut power. |
| Tech Support Fraud | Pop-ups or calls claiming your computer is infected and asking for remote access. |
| Investment / Crypto Scam | Calls pitching fake investment or cryptocurrency opportunities promising guaranteed returns. |
If you receive a suspicious call from a 385 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 Utah Division of 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 (Rocky Mountain Power or Dominion Energy) will never demand immediate payment by gift card, wire transfer, or cryptocurrency. Any 385 caller making such a demand is a scammer.
History and Economy of the 385 Region
n
The 385 area code entered service in 2011 as an overlay for the entire 801 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 385 covers precisely the same cities as 801. The regional economy is anchored by Salt Lake City’s role as the state capital, the “Silicon Slopes” technology corridor, financial services, and the worldwide headquarters of The Church of Jesus Christ of Latter-day Saints, along with the University of Utah, Intermountain Health, and Brigham Young University in Provo. Because 385 is the newer of the two Wasatch Front codes, it appears most often on recently activated mobile numbers and new business lines.

Looking Up a 385 Number
n
To identify a 385 caller, use a reverse phone lookup or search the complete 10-digit number online. Because 385 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.
