Area Code for Sacramento

Sacramento’s dialing identity is built around area code 916 — one of the original 86 codes launched when AT&T established the North American Numbering Plan in 1947. Since 2018, a second code, 279, has operated as an all-services overlay across the identical territory.

Both 916 and 279 serve the Sacramento metro: the city proper, Elk Grove, Roseville, Folsom, Rancho Cordova, and suburbs spanning six counties. The 530 area code begins where the metro ends — it covers the northern California rural belt stretching from the Sierra Nevada foothills through Redding to the Oregon border.

What’s the area code for Sacramento?

Sacramento uses two active area codes that cover the same geography.

Code	Established	Coverage	Notes
916	1947 (metro assignment ~1950)	Sacramento metro, Placer, El Dorado, Yolo, Sutter, Solano counties	Original code; still the dominant Sacramento identifier
279	2018 (overlay)	Exact same territory as 916	All-services overlay; CPUC Decision 17-02-010
530	1997	Far northern CA — Redding, Chico, Davis, Sierra foothills	Split from 916 Nov 1 1997; not a Sacramento code

For a Sacramento business number, 916 carries stronger local recognition — it has been synonymous with the state capital for over 70 years. New lines may receive 279, which is operationally equivalent but less culturally embedded.

Sacramento area codes by region

Downtown Sacramento, Midtown, and East Sacramento — 916 / 279

The historic core of Sacramento — the Capitol building, K Street corridor, Old Sacramento, Midtown, and East Sacramento neighborhoods — sits entirely within the 916/279 overlay. State government offices, lobbyist firms, law offices on J and L Streets, and the Sutter Health system all operate on 916 numbers.

North Sacramento and Natomas — 916 / 279

North Sacramento, Del Paso Heights, and the Natomas basin (home to Sacramento International Airport) carry 916/279 numbers. The former McClellan Air Force Base — now McClellan Business Park — is in this zone. Aerojet Rocketdyne’s Sacramento campus sits nearby in Rancho Cordova.

East and Southeast — Rancho Cordova, Folsom, Elk Grove — 916 / 279

Rancho Cordova, once anchored by Mather Air Force Base (now Mather Airport), is a 916 suburb. Folsom (~82,000 residents) and fast-growing Elk Grove (~175,000) both use 916/279. These southeastern suburbs house logistics hubs, tech campuses, and regional distribution centers.

Roseville and Placer County Suburbs — 916 / 279

Roseville (~150,000 residents), Rocklin, Lincoln, Granite Bay, and Loomis are all within the 916/279 overlay despite being in Placer County. Roseville is one of the fastest-growing cities in California — its tech parks, retail corridor, and NorCal distribution centers all use 916 or 279 numbers.

Davis — 530 (not Sacramento)

Davis is frequently associated with Sacramento because of UC Davis and its proximity. But Davis carries 530, not 916. The 530 split from 916 in 1997 specifically moved Davis and the university into the new northern California code. West Sacramento (across the river from Downtown Sacramento) is 916. Davis is 530.

Northern CA Rural Beyond Sacramento — 530

Area code 530 extends far beyond the Sacramento metro. It covers Redding, Chico, Woodland, Yuba City, Marysville, Auburn, Grass Valley, Nevada City, Susanville, Mount Shasta, and Yreka — a vast territory stretching from the Central Valley farm belt through the Sierra foothills to the Oregon border.

History of Sacramento area codes

The 916 story spans nearly eight decades of California population growth.

1947 — NANP launch. AT&T and the Bell System divided North America into numbering plan areas. California received three codes: 415 (Northern California, including San Francisco), 916 (the far north — Eureka, the coast, and the upper interior), and 213 (everything else, including Los Angeles and initially Sacramento). The digit assignments were deliberate: rotary phones dialed fewer pulses for lower digits, so densely populated regions got lower-numbered codes. Sacramento was initially under 415.

~1950 — Sacramento moves to 916. The NANP regions were redrawn, transferring Sacramento from 415 to 916. This made 916 the Sacramento code it remains today.

1958 — 209 splits for the Central Valley. As Fresno, Stockton, and Modesto grew, 209 was carved from the southern portion of the 916 region.

1959 — 707 splits for the North Coast. The wine country and coast from Santa Rosa to Eureka received their own code, 707, further shrinking the 916 footprint.

1997 (November 1) — The 530 split. This was the most significant change to 916. The entire northeastern portion of 916 — Redding, Yreka, Mount Shasta, Chico, Davis, and the Sierra foothills — was reassigned to the new 530 area code. Sacramento and its immediate suburbs were all that remained. Per NANPA, this left 916 as the only one of the original 86 NANP codes that no longer contains any part of its original territory.

2017 (February 9) — CPUC approves 279 overlay. The California Public Utilities Commission issued Decision 17-02-010, approving an all-services overlay for the 916 region. The CPUC chose overlay over split to avoid forcing existing customers to change numbers — a lesson learned from the disruption caused by geographic splits in the 1990s.

2018 (March 10) — 279 goes live. The 279 area code became effective, and 10-digit dialing became mandatory for all local calls within the overlay. Per the CPUC, this did not change call rates or reclassify local calls as long-distance.

916 as state capital identity

No other metro in the United States has its area code as embedded in government operations as Sacramento’s 916.

California state government is the region’s largest employer. The Capitol building, all constitutional officer offices (Governor, Attorney General, Secretary of State, Controller, Treasurer), the California Legislature (120 Assembly and Senate members plus staff), and hundreds of state agencies all operate from Sacramento — on 916 numbers.

The density of government-adjacent industries this creates is unique. Lobbying firms, state contractors, public affairs consultancies, legislative staffing agencies, and regulatory attorneys all cluster within blocks of the Capitol. Caltrans (the largest state DOT in the US by budget) is headquartered in Sacramento. The California Department of Food and Agriculture (CDFA), which regulates the state’s $60+ billion agricultural economy, runs from Sacramento. UC Davis Medical Center — a top-20 academic medical center — is a 916 institution.

The McClellan and Mather AFB legacy runs deep. Both bases closed in the 1990s, but their conversion to civilian campuses brought aerospace and defense contractors into the 916 orbit. Aerojet Rocketdyne’s Sacramento complex, which has manufactured rocket propulsion systems since 1951, remains one of the largest private employers in the metro.

For any business selling to California state government — IT vendors, consulting firms, professional services, staffing agencies — a 916 number is not merely local presence. It is credibility signal in the specific market segment that writes California’s largest procurement checks.

Sacramento area code spam and scams

The 916 area code is spoofed by scammers specifically because of Sacramento’s state-government identity.

EDD impersonation is the most prevalent California-specific scam. Callers spoof 916 numbers and claim to represent the Employment Development Department, telling targets their unemployment claim has been flagged or that they owe a balance. The EDD does not call to demand immediate payment or personal information over the phone.

Fake state agency alerts (sometimes CalFire-themed during wildfire season) use spoofed 916 numbers to create urgency around evacuation orders or emergency fee demands. Legitimate emergency alerts come through Wireless Emergency Alerts, not individual phone calls requesting payment.

IRS impersonation is a nationwide pattern but hits Sacramento hard because the state-capital context makes government-caller framing more plausible. The FCC spoofing guide notes these calls frequently display official-looking caller IDs.

STIR/SHAKEN is the FCC-mandated call authentication framework that fights this spoofing. Carriers assign an attestation level to every call. A-attestation means the originating carrier verified the calling party is authorized to use that number. Numbers provisioned through compliant carriers — including DialPhone’s 916 and 279 numbers — carry A-attestation by default.

This matters for businesses: your Sacramento business number will display as verified on recipient phones rather than “Spam Risk.” Read the full framework at STIR/SHAKEN glossary.

Sacramento area code FAQ

Sacramento area code FAQ

What is the area code for Sacramento? +

Sacramento uses two area codes: 916 and 279. Area code 916 is the original code assigned to the Sacramento metro in 1950 and is still the dominant code. Area code 279 is an all-services overlay that launched on March 10, 2018, covering the exact same geography.

New phone lines in Sacramento may be assigned either 916 or 279. All local calls within the overlay require 10-digit dialing (area code + 7-digit number). Northern California rural areas beyond the Sacramento metro — including Redding, Chico, Davis, and the Sierra foothills — use area code 530.

Is 530 a Sacramento area code? +

No. Area code 530 covers northern California rural areas but not the City of Sacramento itself. The 530 region includes Redding, Chico, Davis, Woodland, Yuba City, Auburn, Grass Valley, Nevada City, and the Sierra Nevada foothills.

Davis is often associated with Sacramento because UC Davis is nearby, but Davis carries a 530 number, not 916. The Sacramento metro — including Elk Grove, Roseville, Folsom, Rancho Cordova, and Citrus Heights — uses 916 and 279.

When did the 279 area code start? +

The 279 area code became effective on March 10, 2018. The California Public Utilities Commission approved the overlay via Decision 17-02-010 on February 9, 2017, after projections showed the 916 area code was running low on available central office codes.

The CPUC chose an all-services overlay rather than a geographic split so that existing 916 customers would not have to change their phone numbers. Both 916 and 279 have served the identical Sacramento region territory since March 2018.

Why does Sacramento have two area codes? +

Population growth and the explosion of mobile, VoIP, and fax lines exhausted the supply of available 916 numbers. Rather than split the region geographically — which would have forced thousands of residents and businesses to change their numbers — the CPUC used an overlay.

An overlay assigns a second area code (279) to the same territory. Existing 916 customers keep their numbers permanently. New lines issued after March 2018 may receive either 916 or 279, whichever has available inventory.

Do I need to dial 10 digits for local Sacramento calls? +

Yes. Since the 279 overlay launched on March 10, 2018, all local calls within the 916/279 region require 10-digit dialing: area code + 7-digit number. Calls without the area code will receive a recording instructing you to redial with the full number.

This change does not reclassify local calls as long-distance. Rates remain the same — you simply must include the area code even for calls across the street. Emergency numbers (911) and abbreviated dialing codes (211, 311, 411, 511, 611, 711, 811) are unaffected.

How do I get a Sacramento 916 business phone number? +

You do not need a physical Sacramento office to get a 916 or 279 number. Cloud VoIP providers provision Sacramento numbers instantly.

Sign up at dialphone.com/pricing, select a business plan, and search available 916 or 279 numbers during setup. Numbers carry STIR/SHAKEN A-attestation from day one — the highest caller ID trust tier — so your calls display as verified rather than 'Spam Risk' on recipient phones.

What cities are in the 916 area code? +

The 916 area code (and its 279 overlay) covers the greater Sacramento metro across six counties.

Major cities include: Sacramento, Elk Grove, Roseville, Rancho Cordova, Folsom, Citrus Heights, West Sacramento, Arden-Arcade, North Highlands, Lincoln, Rocklin, Loomis, Granite Bay, El Dorado Hills, and Pleasant Grove. The coverage spans Sacramento, Placer, El Dorado, Yolo, Sutter, and portions of Solano counties.

Are 916 area code calls scams? +

Not automatically — 916 is a legitimate Sacramento code. However, scammers spoof 916 numbers to appear local to Sacramento residents, particularly to impersonate California state agencies. Common patterns include fake EDD (Employment Development Department) calls about unemployment claims, IRS impersonation threats, and fraudulent state agency alerts.

Legitimate state agencies do not demand immediate payment over the phone or threaten arrest. If you receive a suspicious 916 call claiming to be a CA government agency, hang up and call the agency back using a number from the official California.gov website.
