Geographic Coverage & Major Cities

Area code 916 covers the Sacramento region in the northern Central Valley, including most of Sacramento County and parts of Placer, Sutter, and Yolo counties. Anchored by the state capital, it takes in a dense ring of suburbs that have grown rapidly over the past two decades.

Cities and communities served by the 916 area code include:

  • Sacramento – the capital of California and the region’s economic and political hub
  • Elk Grove & Rancho Cordova – major southern and eastern suburbs
  • Roseville & Rocklin – fast-growing Placer County communities
  • Folsom & Citrus Heights – established suburbs east and northeast of the city

As the phone code of the seat of California’s government, a 916 number carries strong regional identity for agencies, businesses, and residents across greater Sacramento.

A Brief History of Area Code 916

Area code 916 was one of the original area codes created in 1947, and it once covered a huge swath of northeastern California. In 1997, the rural and mountain counties to the north and east were split off into area code 530, shrinking 916 to the Sacramento metro. As demand kept rising, area code 279 was added as an overlay in 2018, placing a second code over the same territory and making 10-digit dialing mandatory.

Time Zone & Best Time to Call

Numbers in the 916 area code use Pacific Time (PT). The region observes Daylight Saving Time, shifting from PST (UTC-8) to PDT (UTC-7) between March and November each year.

Best time to call: Standard business hours run 9:00 AM to 5:00 PM Pacific, Monday through Friday. Remember the West Coast is three hours behind the East Coast – if you are in New York, wait until noon your time to reach someone at the start of their workday in Sacramento.

How to Dial Phone Numbers in Area Code 916

Because of the 279 overlay, the Sacramento area requires 10-digit dialing on every call.

Is Area Code 916 a Scam? Safety & Protection Tips

Area code 916 is a legitimate California area code – a call from it is not fraudulent by default. However, because 916 is tied to state government, scammers frequently spoof it, faking the caller ID so their number appears to come from an official Sacramento line. Neighbor spoofing, which mimics the first six digits of your own number, is especially common.

How to report, block, and look up 916 callers

  1. Never share personal or financial details with an unexpected caller, however urgent they sound.
  2. Block the number using your phone’s built-in call-blocking feature or a reputable call-screening app.
  3. Look up the number with a trusted reverse phone lookup before returning any call.
  4. Report it to the FTC at reportfraud.ftc.gov and register at DoNotCall.gov.
