What is the 626 Area Code? Time Zone and Location
- Area code 626 is located in California and covers Pasadena, El Monte, West Covina, Alhambra, and Baldwin Park — it is the only area code that serves the San Gabriel Valley numbering plan area described by 626.
- There are currently no overlays, meaning 626 is the sole geographic area code for the regions it serves. Public sources have cited very large population counts tied to broader Southern California reporting; the San Gabriel Valley itself is one of the most densely populated suburban corridors in the United States.
- The most populous cities in area code 626 include Alhambra, portions of Los Angeles, Pasadena, El Monte, and West Covina, with other cities including La Puente, Glendora, Arcadia, Monrovia, Covina, Baldwin Park, Rowland Heights, Azusa, South Pasadena, San Gabriel, and Sierra Madre.
- The 626 area code is located in the Pacific Time Zone — operating on Pacific Standard Time (PST) at UTC−8 during standard time and shifting to Pacific Daylight Time (PDT) at UTC−7 during daylight saving time.
- Area code 626 was put into service on June 14, 1997 and was the 203rd area code in service — one of 43 area codes introduced in 1997 — created to relieve pressure on the 818 area code as numbers in 818 were being exhausted.
- Previously, the San Gabriel Valley shared the 818 designation with the San Fernando Valley — rapid growth and new communication technologies exhausted available numbers in 818, prompting NANPA to split the eastern San Gabriel Valley into the new 626 code.
- 10-digit dialing is mandatory for all local calls within the region.

| Common Labels | Robocaller, SSA arrest threat, “Can you hear me?” voice recorder, IT sales harasser, home improvement deposit fraudster, auto warranty harasser |
| Spoofing Risk | Scammers fake their caller ID to display local or familiar 626 numbers — if you live in or near California (Pasadena, El Monte, West Covina), scammers know you are more likely to answer what appears to be a local San Gabriel Valley call |
| Typical Strategy | Neighbor spoofing — appearing as a familiar Pasadena, Alhambra, or West Covina number to build trust before making fraudulent demands |
| Signature Scam — SSA “Legal Enforcement Action” Threat | Automated robocalls claim that “legal enforcement action” has been filed against your Social Security Number for fraudulent activity — sometimes specifically mentioning misuse in Texas — threatening that you'll be taken to the state courthouse or that an arrest warrant will be issued if you don't call back immediately, with the callback number displayed as a local 626 number to appear legitimate |
| Signature Scam — “Can You Hear Me?” Voice Signature Capture | Callers open with a simple question like “Can you hear me okay?” to get you to say “Yes” — recording your voice saying “Yes” and using that recording as a voice signature to authorize fraudulent charges to your phone bill or credit card, often hanging up immediately after you respond with no further conversation |
| Signature Scam — Unwanted IT Sales Calls | The 626 area code is notably targeted by aggressive, unsolicited IT product and services sales calls — exploiting the region's large number of technology and research employers like Caltech and JPL to make cold calls seem relevant |
| Signature Scam — Home Improvement Deposit Fraud | Home improvement scams are the single most commonly reported spam category for the 626 area code — callers target San Gabriel Valley homeowners about roofing, solar panels, HVAC, and remodeling, collecting upfront deposits for work that is never performed |
| Common Legitimate Callers | Local residents, Huntington Hospital, Panda Restaurant Group, Caltech, Pasadena City College, and government agencies like the Pasadena Police Department and Arcadia Unified School District are among the most recognized legitimate callers from 626 numbers |
| Key Risk Indicator | SSA robocalls mentioning a “legal enforcement action” or arrest warrant, calls that open with “Can you hear me okay?” and hang up immediately, unsolicited home improvement quotes requiring immediate deposits, or aggressive IT sales calls |
| Safety Tip | The Social Security Administration never calls to threaten arrest — they communicate by mail. No legitimate company opens calls by trying to record you saying “yes.” Always hang up and contact organizations directly through their official websites before taking any action |
