What is the area code for Salt Lake City?

The area code for Salt Lake City, Utah is 385, with overlay code 801 sharing the same geographic footprint. The 385 area code is a North American Numbering Plan geographic code assigned in 2009, covering the Salt Lake-Ogden-Provo region. It serves approximately 1,600,000 residents on the Mountain Time (MT) (UTC-7 / UTC-6 DST).

The 385 area code has 490 assigned central-office prefixes (NXX codes, the three digits after the area code) across 20 rate centers, with numbers allocated to roughly 44 carriers.

At 490 of the ~792 usable central-office prefixes, the 385 area code has about 62% of its numbering capacity assigned, and that near-exhaustion is part of why overlay code 801 was added to the region. See how 385 compares in our NXX prefix allocation analysis across 338 US area codes. (Prefix data: localcallingguide.com / NANPA, 2026.)

History of the 385 area code

The 385 area code was introduced in 2009 when the North American Numbering Plan was first deployed. As Salt Lake City grew and number demand increased, overlay code 801 was added to serve the same geographic region, a common solution that avoids forcing existing subscribers to change their numbers.

• 1947 801 added to serve the same region
• 2009 385 entered service

Is the 385 area code safe? Spam and scam calls

385 is a legitimate geographic area code for Salt Lake City: it is not a scam code or a premium-rate prefix, and a call from a 385 number is most likely a genuine local caller. The risk is not the area code itself but a tactic called neighbor spoofing: scammers fake their caller ID so an unwanted call appears to come from your own area code, because people answer familiar numbers more readily.

If you get an unexpected 385 call, a few signals point to a likely scam, a pre-recorded message, urgent pressure to act now, a demand for payment by gift card or wire transfer, or anyone asking for passwords, Social Security, or account numbers. Let suspicious calls go to voicemail, never share personal information, and report fraud to the FTC at reportfraud.ftc.gov.

The FCC consumer guide on spoofing explains your rights under the Truth in Caller ID Act. A real Salt Lake City business will leave a clear voicemail and will not pressure you.

US carriers verify caller ID with the STIR/SHAKEN framework, which flags many spoofed numbers as "Spam Likely" before they ring. DialPhone 385 numbers are registered for STIR/SHAKEN attestation, so calls from your business are verified as genuine and reach customers without a false spam label. See the DialPhone guide to VoIP security for more.

Why get a 385 area code number for your business?

Getting a 385 number gives your business three measurable advantages over a toll-free or out-of-area number:

1. Local trust signal. Customers in Salt Lake City recognize 385 as their home area code. Caller ID matching builds immediate credibility for service businesses, sales outreach, and patient communication.
2. Higher answer rate. Calls from a familiar local area code are answered more often than unknown or toll-free numbers, which matters most for outbound sales, appointment confirmations, and time-sensitive service callbacks.
3. Targeted marketing. Businesses serving Salt Lake City and the broader Salt Lake-Ogden-Provo can advertise a local number across print, radio, billboards, and digital channels for higher conversion than a national 800 number.

For businesses in Salt Lake City and surrounding cities, top industries that benefit from local 385 presence include Professional Services, Healthcare, and Retail. DialPhone's AI receptionist is available for every 385 number, never miss a call, even after standard business hours.

What to know before getting a 385 number

• Number availability is finite. Popular Salt Lake City area codes can be inventory-constrained, request specific vanity patterns early.
• Porting timing varies. Most 385 ports complete in 2-5 business days; complex multi-line legacy contracts can take 7-10.
• HIPAA tier required for healthcare. The Core $24 plan doesn't include a BAA, healthcare users need Advanced ($34) or above.

Cities and Communities in the 385 Area Code

The 385 area code overlays the older 801 code across Utah's five-county Wasatch Front, Salt Lake, Utah, Davis, Weber, and Wasatch counties. It reaches roughly 29 communities, from Ogden in the north through Salt Lake City to Provo in the south, the state's densest population and business corridor.

City	County	Business character
Salt Lake City	Salt Lake	State capital; finance, technology, and headquarters corridor
West Valley City	Salt Lake	Second-largest city in Utah; manufacturing and logistics
Provo	Utah	University city anchoring the Silicon Slopes software cluster
Ogden	Weber	Aerospace, outdoor-industry, and rail-logistics hub
Sandy	Salt Lake	South-valley retail, professional services, and tech offices

Because 385 is an overlay rather than a split, every one of these cities is served by both 385 and 801, the two codes share the same geography instead of dividing it, so a 385 number reads as local anywhere along the Wasatch Front.

385 by the Numbers: Prefixes, Rate Centers, and Dialing

Public numbering records list the 385 code with 490 assigned NXX prefixes across 20 rate centers, allocated among 44 carriers, a large, actively used inventory that reflects genuine Wasatch Front demand rather than a thinly populated overlay.

The overlay was phased in across 2008-2009 to add capacity as 801 approached exhaustion. Existing 801 customers kept their numbers, and 385 is issued to new lines. Since June 1, 2009, all local calls in the 801/385 region require 10-digit dialing, area code plus number.

To Utah customers, 385 and 801 are interchangeable, neither reads as newer or more distant. If you want a Salt Lake or Provo number today, 385 typically has far more available inventory than the older 801 code.

Why Utah Businesses Choose a 385 Number

The Salt Lake-Provo corridor, widely known as Silicon Slopes, is a major Mountain West technology hub, while Ogden and Provo add aerospace, manufacturing, and university-driven demand. A 385 number places your business inside that market with the same local credibility as a legacy 801 line.

For a company opening a Wasatch Front presence without a physical office, a virtual 385 number gives customers a familiar local code to reach, and local numbers see materially higher answer rates than out-of-area or toll-free lines.
