Regulatory Oversight and Dialing Formats

The California Public Utilities Commission (CPUC) regulates area code 916 and ensures fair practices and consumer protection within the telecommunications industry. The CPUC manages area code changes, approves new area codes, and addresses consumer complaints related to telecommunications services.

The North American Numbering Plan Administration (NANPA) oversees the overall numbering plan, coordinating area code assignments and managing NANP resources.

The standard dialing formats for 916 are as follows:

• Local Calls: 1 + 10 digits (area code + 7-digit number). Dial the full 10-digit number even for local calls within the 916 area code. This requirement stems from the introduction of the 279 overlay area code.

  • 211: Community services and information
  • 311: Non-emergency municipal services
  • 411: Directory assistance
  • 511: Traffic and transportation information
  • 611: Telecommunications carrier customer service

History of Area Code 916: From 1947 to Today

Established in October 1947, area code 916 became one of California's original three area codes, alongside 213 and 415. Initially, 916 covered the far northern portion of the state. In 1950, California realigned its area codes and redrew 916 to cover the northeastern corner.

Timeline of Changes:

• October 1947: Area code 916 created as one of California's original three area codes
• 1950: Realigned to serve northeastern California; Sacramento moved from 415 to 916
• 1958: Area code 209 created for southern portion (Fresno, Stockton, Modesto), reducing 916's coverage
• November 1, 1997: Area code 530 created for northeastern region (Redding, Yreka, Davis); Dixon reassigned to 707. This split made 916 the only original NANP area code that no longer contains any part of its original 1947 territory (Wikipedia - Area codes 916 and 279).
• February 9, 2017: CPUC approved area code 279 as an overlay
• February 10, 2018: Mandatory 10-digit dialing implemented; transition period began
• March 10, 2018: Area code 279 launched; carriers began assigning new numbers from 279 pool (CPUC Decision)

10-Digit Dialing Transition: Mandatory 10-digit dialing took effect on February 10, 2018. During the transition period (February 10 – March 10, 2018), 7-digit calls still completed but included reminders to switch to 10-digit dialing. After March 10, 2018, all calls required the full 1 + area code + 7-digit format.

Number Assignment: When you order new telephone lines or services in the 916/279 area, carriers may assign numbers from either pool. The specific area code depends on availability within your local central office (exchange). Both area codes serve the identical geographic region, and carriers manage assignment under NANPA guidelines. You typically cannot choose which area code you receive for new service.

Telecommunications Providers Serving Area Code 916

Several major telecommunications providers offer services within the 916 area code:

• AT&T: Offers a wide range of services, including wireless, landline, internet, and fiber optic solutions.
• Verizon: Provides wireless, landline, internet, and Fios fiber optic services.
• T-Mobile: Primarily a wireless carrier, also offering prepaid and home internet services.

Number Porting: Keep your existing 916 or 279 phone number when switching providers through Local Number Portability (LNP). Contact your new provider to initiate porting; they will coordinate the transfer with your current carrier. The process typically takes 7–10 business days for landlines and 1–2 days for wireless numbers.

Future Changes and Considerations

Area code 916 may experience further changes due to ongoing demand for new telephone numbers. While no immediate changes are planned, the CPUC continually monitors phone number availability and may implement additional overlays or splits as needed.

Number Exhaustion Status: NANPA's most recent exhaust analysis shows no near-term exhaustion projected for the 916/279 overlay. The CPUC and NANPA publish regular reports on number utilization and provide public notice well in advance of any required changes.

Staying Informed: Monitor potential changes through:

• CPUC Area Codes and Numbering page: https://www.cpuc.ca.gov/industries-and-topics/internet-and-phone/area-codes-and-numbering
• NANPA's website: https://www.nanpa.com
• Your telecommunications carrier will notify you directly of any mandatory changes

Best Practices and Troubleshooting: Understanding Calls from 916

Follow these best practices to ensure smooth communication within the 916 area code:

• Always dial 1 + the 10-digit number: Dial this format for both local and long-distance calls due to the 279 overlay.
• Update contact lists: Ensure all your contacts include the area code.
• Is it safe to answer calls from 916? While 916 is a legitimate Sacramento area code, scammers often use local area codes to appear trustworthy through "caller ID spoofing." Exercise caution with unsolicited calls and never provide personal information unless you've verified the caller's identity.
• Check your phone system's compatibility: Ensure your phone system, including PBX and alarm systems, supports 10-digit dialing.

Scam Verification and Reporting:

• Verify unknown callers by hanging up and calling back using a number from an official website or directory
• Report suspected spoofing scams to the FCC at https://www.fcc.gov/consumers/guides/spoofing
• File complaints with the FTC's Consumer Response Center for fraud-related calls
• Use call-blocking apps or services that identify potential spam calls
• Register your number with the National Do Not Call Registry at www.donotcall.gov

Common Dialing Errors and Solutions:

• Error: Call doesn't complete, recording says to "hang up and dial again"
  • Solution: Ensure you're dialing 1 + area code + 7-digit number (1-916-555-1234)
• Error: Call goes to wrong number or "number not in service" message
  • Solution: Verify the correct area code (916 or 279) and re-dial carefully
• Error: Long-distance charges for local calls
  • Solution: Contact your carrier; dialing "1" does not make a call long-distance—your rate plan determines call costs
• Error: Fax machine or alarm system not connecting
  • Solution: Reprogram equipment to dial with 1 + area code; consult manufacturer documentation
