Area code 626

About area code 626

NANPA lists 626 as an in-service geographic area code for California, first put into service on June 14, 1997. It is not part of an overlay, so every number in its territory starts with 626. It is in the Pacific time zone. The places with the most assigned exchanges include Alhambra, Pasadena, Covina, El Monte, and La Puente. By population, its largest named places are Pasadena, El Monte, Alhambra, Arcadia, and Covina.

For a storefront or service area inside 626, the place pages show which prefixes are rated local there.

Dialing 626 numbers

According to NANPA's dialing-plan data, local calls within 626 are dialed as 1 plus ten digits and toll calls as 1 plus ten digits. Ten-digit local dialing means the area code is part of how customers save and recognize your number, so print it in full everywhere.

Who holds 626 exchanges

38 carriers hold the 734 central office codes assigned in 626. Pacific Bell has the most, with 115 (16%). 513 of the codes (70%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. Numbers can move between carriers through porting, so a code's holder tells you where the block started, not where every number lives now.

Rate centers and towns in 626

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 626 has codes in 10 rate centers. The table lists the rate centers with the most codes, with the matching Census place where the abbreviation could be matched.

Number supply in 626

An area code has 800 possible central office codes that start with 2 through 9, a few of which are reserved (such as N11 service codes and 555). 734 are assigned in 626, 92% of 800. 115 were assigned in 2020 or later. NANPA reports relief planning in progress for 626, the process used to add a new area code when one is projected to run out of codes.

Callata is a business phone system priced at $99 a month with 5 users included, then $20 per additional user.

Optional AI agents (receptionist, sales, support or scheduler) can answer calls after hours or when nobody picks up, take messages, text, email and transfer to your team. They are billed from prepaid AI minutes at $0.25 per minute, identify themselves as AI, and may only place outbound calls to people who consented, between 8am and 9pm.
