Area Code for Salt Lake City
Salt Lake City uses area codes 801 (1947 original) and 385 (2008 overlay). History, Wasatch Front coverage, scam alerts, and how to get a local SLC business number.
Salt Lake City’s Wasatch Front runs on two area codes — 801 (1947 original) and 385 (2008 overlay) — making it one of the most densely coded urban corridors in the Mountain West.
The rest of Utah uses area code 435 (rural and southern regions, including Park City). If a number starts with 801 or 385, it’s Wasatch Front. If it starts with 435, it’s everywhere else in the state.
This guide covers the full picture: history, neighborhood-level coverage, the cultural weight of 801, Utah-specific phone scams, and how to get a business number for either code in minutes.
What’s the area code for Salt Lake City?
Salt Lake City and the Wasatch Front are served by two area codes sharing the same geography:
| Code | Established | Type | Coverage | Notes |
|---|---|---|---|---|
| 801 | 1947 | Original | Wasatch Front (SLC, Provo, Ogden, suburbs) | One of the original 86 NANP codes; most recognized Utah code |
| 385 | Jun 1, 2008 | Overlay | Same as 801 | All-services overlay; approved by Utah PSC; 10-digit dialing mandatory Jun 2009 |
Both codes share the Mountain Time Zone (MT) — UTC−7 in winter, UTC−6 in summer.
A practical rule: 801 numbers tend to be older established lines (businesses, long-tenured residents, landlines). 385 numbers are predominantly newer wireless and VoIP assignments from 2008 onward. Both are equally local — no geographic distinction exists between them.
SLC metro area codes by region
The 801/385 overlay has no internal geographic boundary. Either code can appear anywhere in the Wasatch Front. Here’s how the broader metro breaks down:
Downtown SLC, Sugar House, and The Avenues
Downtown Salt Lake City — including Temple Square, the Gateway District, and the Capitol — is the densest 801 concentration in the state. Sugar House (one of SLC’s oldest neighborhoods) and The Avenues hillside district both sit solidly within the overlay.
West Valley City and Taylorsville
West Valley City is Utah’s second-largest city and sits immediately west of SLC proper. Along with Taylorsville and Kearns, it anchors a high-density 801/385 corridor west of I-215.
Sandy, Draper, and South Jordan
The southern suburban belt — Sandy, Draper, South Jordan, Riverton, and Herriman — are all within the 801/385 overlay. Draper is home to several tech companies including Ancestry.com and InsideSales (now XANT).
Lehi — Silicon Slopes hub
Lehi sits at the northern tip of Utah County and is the center of Utah’s tech economy. Adobe’s North America product campus, Domo, Pluralsight (HQ), Qualtrics (co-HQ), and Vivint Smart Home all operate here. Lehi uses 801 (and increasingly 385).
Provo and Orem
Provo is ~45 miles south of SLC but fully inside the 801/385 overlay. Brigham Young University (BYU), UVU, and a dense startup ecosystem anchor this sub-market. Qualtrics was founded in Provo. Orem is adjacent to the north.
Ogden and Davis County
Ogden (Weber County seat, ~30 miles north of SLC) and the Davis County cities — Bountiful, Layton, Kaysville, Clearfield — are all 801/385 territory. Hill Air Force Base in Layton adds significant federal telecom volume to this corridor.
Park City (area code 435 — not 801)
Park City is in Summit County, which uses area code 435. Despite its fame for Sundance Film Festival and ski resorts (Park City Mountain, Deer Valley), it sits outside the Wasatch Front overlay. The SLC International Airport — the primary gateway for Park City visitors — is 801.
History of Salt Lake City area codes
Utah’s area code history is a three-chapter story of population growth concentrated on the Wasatch Front.
1947 — 801 is born. AT&T engineers design the North American Numbering Plan (NANP) and assign area code 801 to the entire state of Utah. It’s one of the original 86 NPAs.
Utah’s low population (~690,000 in 1950) meant it received a higher-numbered code — rotary dial mechanics favored low-number codes for high-population areas because fewer pulses meant faster dialing. The “0” in position two (801) signaled Utah was a single-NPA state; multi-code states used “1” in that position.
1997 (September 21) — 435 splits off rural Utah. Explosive Wasatch Front growth — mobile phones, pagers, fax machines — strains 801’s number supply within 50 years. The fix: peel rural and southern Utah away. Area code 435 takes everything outside the Wasatch Front: St. George, Moab, Logan, Cedar City, Park City. Area code 801 is now confined to the five Wasatch Front counties.
2000 — Utah PSC approves future overlay. The Public Service Commission of Utah approves a code action for 801. An initial plan proposed splitting Salt Lake County (keep 801) from the rest of the Wasatch Front (new 385). Number pooling and conservation measures postpone implementation.
2007 (July) — PSC announces overlay activation. Conservation measures are exhausted. The PSC announces 385 will launch as a full overlay — covering the same geography as 801 — rather than a split. No one loses their existing 801 number.
2008 (June 1) — 385 activates. Area code 385 enters service. A 12-month permissive dialing period begins. Sources: NANPA, Utah Public Service Commission.
2009 (June 1) — 10-digit dialing mandatory. All local Wasatch Front calls must use 10 digits. The 7-digit habit ends.
2030s — NANPA projects next review. With two codes covering the same geography, the 801/385 complex is projected to remain sufficient through the 2030s. No third code is currently planned for the Wasatch Front.
801 as SLC / Wasatch Front identity
Area code 801 carries cultural and economic weight beyond a phone prefix.
LDS Church headquarters. The Church of Jesus Christ of Latter-day Saints — the dominant cultural institution in Utah — has its world headquarters at Temple Square in downtown Salt Lake City. The LDS Church is one of the largest landowners in the 801 overlay and a significant employer. Its administrative and commercial presence anchors SLC’s business identity.
2002 Winter Olympics legacy. Salt Lake City hosted the 2002 Winter Olympics. The event left behind upgraded infrastructure (I-15 reconstruction, TRAX light rail, SLC airport expansion) that accelerated Wasatch Front population growth — and directly drove demand for new 801 numbers through the 2000s.
Sundance Film Festival gateway. Robert Redford’s Sundance Film Festival operates out of Park City (area code 435) but SLC International Airport (801) is the primary arrival hub. Every January, tens of thousands of visitors and media pass through the 801 corridor.
Utah Jazz and Real Salt Lake. The NBA’s Utah Jazz (founded 1974) plays at the Delta Center in downtown SLC — an 801 address. Real Salt Lake (MLS) plays at America First Field in Sandy — also 801. Both franchises generate substantial local brand and telecom volume.
University of Utah. The U’s main campus sits at the eastern edge of SLC, directly in the 801 overlay. It’s a major research university (Pac-12), a top-10 NIH-funded medical school, and the origin of several Silicon Slopes spinouts.
BYU (Provo, 801). Brigham Young University in Provo is one of the nation’s largest private universities. Its 801 address places it inside the same overlay complex as SLC despite the 45-mile separation.
Silicon Slopes tech corridor. The stretch from Lehi south through Provo — branded “Silicon Slopes” — is one of the fastest-growing tech hubs in the US. Adobe (North America product campus, Lehi), Domo (American Fork), Pluralsight (Farmington / Draper), Qualtrics (Provo/Seattle), Vivint (Lehi), and Overstock.com (Midvale) all operate under 801 or 385. The density of tech lines drives faster overlay demand than a comparable non-tech metro would generate.
Goldman Sachs SLC office. Goldman Sachs operates one of its largest US back-office hubs in Salt Lake City, employing thousands of finance and technology professionals under 801 area code lines.
SLC area code spam and scams
Utah-specific phone scams that exploit 801 and 385 caller ID trust:
Fake LDS/charity donation scams. Scammers impersonate LDS Church representatives or LDS-affiliated charities, calling with spoofed 801 numbers to solicit donations. The script targets residents who associate the 801 prefix with trusted community institutions. The LDS Church does not solicit tithing or donations by unsolicited phone call.
IRS impersonation. A nationwide scam but with a Utah-specific spike during tax season. Callers claim a federal tax lien or warrant using spoofed 801 numbers. The IRS initiates contact by mail, not by phone call.
Rocky Mountain Power impersonation. Callers posing as Rocky Mountain Power (the dominant Utah utility) threaten immediate power shutoff unless payment is made by gift card or wire. Rocky Mountain Power never demands instant phone payment — verify your account directly at rockymountainpower.net.
Fake Sundance / ski resort booking scams. Each January, scammers run fake accommodation and ticket booking schemes for Sundance Film Festival and Park City ski resorts, often using spoofed 801 or 435 caller IDs. Book only through official festival and resort websites.
Fake delivery notifications. Generic package-not-delivered texts with spoofed 801 numbers directing recipients to phishing sites. USPS, FedEx, and UPS do not require payment to release packages.
STIR/SHAKEN and what it means for your business. The FCC mandates that carriers implement STIR/SHAKEN — a call authentication framework assigning each outbound call an attestation level. A-attestation means the carrier has verified the calling party owns the number. B is partial. C is unverified — the signature of spoofed scam calls.
When you get an 801 or 385 number through DialPhone, outbound calls carry A-attestation — the highest trust level — so your business calls reach customers as verified, not flagged as “Spam Likely.”

How to get a Salt Lake City business phone number
Getting an 801 or 385 number for your business takes under 10 minutes through a cloud VoIP provider. No Utah office required.
Step 1: Choose your area code. Both 801 and 385 carry equal local credibility on the Wasatch Front. If 801 specifically matters for brand recognition, check availability first — older code, more limited inventory.
Step 2: Sign up with DialPhone. Search available SLC numbers by area code during signup. Filter by 801 or 385 depending on availability and preference.
Step 3: Assign the number to your team. Route the SLC number to your mobile, desktop app, or a shared team queue. Add a voicemail greeting, call menu, or AI receptionist as needed.
Step 4: Set outbound caller ID. Configure your 801 or 385 number as the outbound caller ID — so calls you make show the local number, not a toll-free number or personal cell.
Step 5: Port existing numbers if needed. Already have an SLC number with another carrier? Bring it to DialPhone through number porting. US local number ports typically complete in 2–5 business days.

SLC area code FAQ
Salt Lake City area code FAQ
What is the area code for Salt Lake City?
Salt Lake City uses two area codes: 801 and 385. Area code 801 is one of the original North American area codes, established in 1947 when AT&T created the North American Numbering Plan — it once covered all of Utah and remains the most recognized SLC code.
Area code 385 was added on June 1, 2008, as an all-services overlay when the 801 number pool neared exhaustion. Both codes cover the same Wasatch Front geography: Salt Lake, Davis, Weber, Utah, and Morgan counties. Ten-digit dialing became mandatory on June 1, 2009.
Is 385 a Salt Lake City area code?
Yes. Area code 385 is a full Salt Lake City / Wasatch Front area code, introduced on June 1, 2008, as an overlay to area code 801. It covers the identical geographic territory — Salt Lake City, Provo, Ogden, West Valley City, Lehi, Sandy, Draper, and surrounding communities.
Because 385 is an overlay rather than a split, a 385 number is just as locally credible as an 801 number. New wireless and VoIP lines assigned after 2008 are commonly 385. Businesses choosing between the two should check availability — 801 inventory is older and more limited.
What cities are in the 801 area code?
Area code 801 (and its overlay 385) covers the Wasatch Front, including: Salt Lake City, West Valley City, Provo, West Jordan, Orem, Sandy, Ogden, Layton, South Jordan, Taylorsville, Millcreek, Draper, Lehi, Murray, Bountiful, and Riverton.
The five counties served are Salt Lake, Utah, Davis, Weber, and Morgan. Park City (Summit County) uses area code 435, not 801. Provo and BYU are within the 801/385 overlay despite being ~45 miles south of downtown SLC.
Why does Salt Lake City have two area codes?
Salt Lake City has two area codes because population growth on the Wasatch Front outpaced available 801 phone numbers. Area code 801 originally covered all of Utah in 1947. Rural and southern Utah was split off as area code 435 in 1997, leaving 801 for the denser Wasatch Front.
Even the smaller 801 territory filled rapidly due to mobile phones, pagers, VoIP lines, and the Silicon Slopes tech corridor. The Utah Public Service Commission approved 385 as an all-services overlay in 2008 rather than a geographic split — so existing customers kept their 801 numbers unchanged.
Are calls from 801 or 385 numbers spam?
Not inherently. Thousands of legitimate Utah businesses use 801 and 385 numbers daily. The issue is spoofing — scammers fake a local SLC caller ID to increase answer rates.
Common Utah-specific scams include fake LDS/charity donation requests, IRS impersonation, Rocky Mountain Power shutoff threats, and fake Sundance or ski resort booking calls. STIR/SHAKEN (FCC-mandated call authentication) assigns calls an attestation level: A (fully verified), B (partial), or C (unverified). Spoofed scam calls typically receive C-attestation and display as 'Spam Likely.' A DialPhone 801 or 385 number carries A-attestation — the highest trust level.
Can I get a Salt Lake City phone number without a Utah office?
Yes. Virtual (VoIP) phone numbers are not tied to a physical location. Any business can get an 801 or 385 number through a cloud phone provider and route calls to any device — mobile, desktop app, or team queue — anywhere in the US.
DialPhone assigns available SLC numbers within minutes. No Utah office, no hardware, and no long-term contract required. Outbound calls display your SLC number as caller ID. If you already have an 801 or 385 number with another carrier, number porting to DialPhone typically takes 2–5 business days.
What time zone is the 801 area code?
Area codes 801 and 385 are both in the Mountain Time Zone (MT). Mountain Standard Time (MST) is UTC−7, and Mountain Daylight Time (MDT) is UTC−6. Utah observes daylight saving time, switching on the second Sunday in March and reverting on the first Sunday in November.
For business scheduling: Salt Lake City is 2 hours behind New York (ET), 1 hour behind Chicago (CT), and 1 hour ahead of Los Angeles (PT).
What area code is Park City, Utah?
Park City uses area code 435, not 801 or 385. Park City is in Summit County, which falls outside the Wasatch Front overlay complex. Area code 435 covers rural and southern Utah including Park City, St. George, Moab, Logan, and Cedar City.
Salt Lake City International Airport — the main arrival point for Sundance Film Festival and ski tourism — uses area code 801. So even though Park City itself is 435, the broader ski tourism infrastructure is largely 801.

A verified 801 or 385 number builds instant Wasatch Front trust — whether you’re a national company entering the Utah market or a local business that wants calls answered rather than screened as spam.
