Quick answer: The 916 area code covers Sacramento, California's state capital, plus a ring of suburbs across six counties (Sacramento, Placer, Yolo, El Dorado, plus portions of Sutter and Solano). It runs on Pacific Time and has served the region since 1947 as one of the original 86 NANP codes. Two splits trimmed it down (707 in 1959, 530 in 1997), and the 279 overlay went into service in March 2018 — which is why every local call now requires the full 10 digits.
916 Area Code: What It Covers and How to Get a Number
Call a Sacramento business from an unknown number and there's a good chance it goes straight to voicemail. Local callers screen aggressively, and an out-of-state prefix reads as a sales pitch before anyone says hello.
A familiar Sacramento prefix flips that instinct. It signals you're nearby, reachable, and worth picking up for.
This guide breaks down exactly what the 916 area code covers, the cities and counties inside it, the dialing rules after the 279 overlay, and how any business can claim a local Sacramento number — even from another state.
Where the 916 area code is located
The 916 area code serves Sacramento, California's state capital, along with a wide ring of suburbs and smaller communities around it. It sits in the Pacific Time Zone.
Geographically, the coverage stretches from the Sacramento River delta up toward the Sierra Nevada foothills. That spread is wider than most people assume.
The six counties inside the region
Coverage touches six counties, not the three or four many guides list. Here's the accurate breakdown.
| County | Notable cities |
|---|---|
| Sacramento | Sacramento, Elk Grove, Folsom, Citrus Heights, Rancho Cordova, Carmichael |
| Placer | Roseville, Rocklin, Lincoln, Loomis, Auburn |
| Yolo | Davis, Woodland, West Sacramento |
| El Dorado | Placerville, Cameron Park, El Dorado Hills, South Lake Tahoe |
| Sutter | Portions near the southern county line |
| Solano | A small eastern strip only |
The cities that anchor the market
Sacramento itself is the population core, but the suburbs carry serious commercial weight. Roseville, Elk Grove, and Folsom are growth engines in their own right.
That mix matters for businesses. A single Sacramento prefix gives you reach across government, healthcare, retail, and tech buyers in one connected market.
A short history of the 916 prefix
The story here is one of repeated splits — proof of how fast Northern California grew.
1947 to 1950: the original boundaries
The prefix went into service in 1947 as one of the original 86 North American area codes. Oddly, it didn't even include Sacramento at first.
A 1950 realignment redrew the map, pulling the capital and the northeastern corner of the state under the 916 umbrella. That set the stage for everything after.
1959 and 1997: two major splits
Growth forced the territory to shrink twice. In 1959, the 707 area code split off to cover the coast and wine country.
Then in November 1997, the 530 area code carved away the far north — Redding, Davis-adjacent outskirts, and Mount Shasta — leaving 916 focused tightly on greater Sacramento.

The 279 overlay and what changed
By the mid-2010s, the supply of available 916 numbers was running thin. The fix was an overlay rather than another split.
When 279 arrived
Area code 279 entered service in March 2018. An overlay means 279 covers the exact same geography as 916 — same cities, same counties, no new boundary lines.
Existing customers kept their 916 numbers untouched. New lines simply started drawing from the 279 pool once 916 combinations ran low.
Mandatory 10-digit dialing
The overlay introduced one practical change everyone in the region had to absorb: you now dial all ten digits for local calls.
Seven-digit dialing no longer connects. Whether the other party has a 916 or 279 number, the full area code plus the seven-digit number is required.
How to dial in and around Sacramento
The rules are simple once the overlay logic clicks. Here's the quick reference.
Local calls within the region
Dial the three-digit area code (916 or 279) followed by the seven-digit number. That's it — ten digits, every time.
This applies even when you're calling a neighbor across the street. The number's prefix doesn't change the rule.
Long-distance and international calls
For a long-distance call from inside the region, dial 1, then the destination area code, then the seven-digit number.
International callers reaching a Sacramento line dial their exit code, then 1, then 916 (or 279), then the local number. The clean format to share is +1-916-XXX-XXXX.
Why a local number still matters for business
You might wonder whether a specific area code matters in a mobile, work-from-anywhere world. For local trust, it absolutely does.
Answer rates and credibility
People answer calls from familiar prefixes far more often than unknown ones. A Sacramento number reads as legitimate before a word is spoken.
It also signals commitment. Customers assume a local number means a local stake in the community — and that assumption builds trust fast.
You don't need a Sacramento office
Here's the part that surprises people: a virtual number decouples your phone presence from your physical address.
A consultant in Denver or a support team in Austin can run a Sacramento line. Calls forward to any device, and the caller only ever sees the local prefix.

What to do next
The 916 area code isn't just a routing prefix — it's a 75-year-old trust signal for one of California's fastest-growing markets. Owning a piece of it is a genuine competitive edge.
Decide on your call volume, then test a number. If you serve Sacramento customers, a local line will likely pay for itself in answered calls alone.

Frequently asked questions about the 916 area code
When was the 916 area code established?
It went into service in 1947 as one of the original North American area codes.
A 1950 realignment redrew its boundaries to include Sacramento, and later splits in 1959 and 1997 narrowed it to the greater Sacramento region it serves today.
Do I have to dial all ten digits in Sacramento?
Yes. After the 279 overlay launched in March 2018, ten-digit dialing became mandatory for every local call. Dialing only the seven-digit number will not connect, regardless of whether the line is a 916 or 279 number.
Which counties does the 916 region cover?
Six: Sacramento, Placer, Yolo, and El Dorado in full, plus portions of Sutter and a small strip of Solano. That includes cities such as Roseville, Elk Grove, Folsom, Davis, and Auburn.
Is 279 a different region from 916?
No. 279 is an overlay, so it covers the identical geography. The two codes share the same cities and counties — 279 simply adds more available numbers to the same area.
Can I get a 916 number if my business is outside California?
Yes. A virtual number assigns you a Sacramento prefix while calls forward to any device, anywhere. You get the local presence without needing a physical office in the region.
Will a 916 virtual number work with my existing phones?
It will. Calls route to mobiles, desk phones, softphone apps, or a browser — whatever you already use. No new hardware is needed to start taking calls.
How fast can I get a Sacramento number running?
Most businesses are live within an hour. Choosing a new number is near-instant; porting an existing one typically takes a few business days to complete.
