Area code 626 is shown in red. **Area code 626** is a telephone [area code](/source/Area_code) in the [North American Numbering Plan](/source/North_American_Numbering_Plan) (NANP) for most of the [San Gabriel Valley](/source/San_Gabriel_Valley) in the [U.S. state](/source/U.S._state) of [California](/source/California). The [numbering plan area](/source/Numbering_plan_area) (NPA) also comprises nearby areas in the northeastern portion of [Los Angeles County, California](/source/Los_Angeles_County%2C_California), including [Arcadia](/source/Arcadia%2C_California), [Monrovia](/source/Monrovia%2C_California), [El Monte](/source/El_Monte%2C_California), most of [Pasadena](/source/Pasadena%2C_California) and [West Covina](/source/West_Covina%2C_California). The numbering plan area was created in an [area code split](/source/Area_code_split) of [area code 818](/source/Area_code_818) on June 14, 1997. ## History The service area was originally contained in numbering plan area [213](/source/Area_code_213), which was split to create 818 in 1983, before splitting again in 1997. Prior to October 2021, area code 626 had telephone numbers assigned for the [central office code](/source/Central_office_code) 988. In 2020, *988* was designated nationwide as a dialing code for the [National Suicide Prevention Lifeline](/source/National_Suicide_Prevention_Lifeline), which created a conflict for exchanges that permit [seven-digit dialing](/source/Seven-digit_dialing). This area code was therefore scheduled to transition to [ten-digit dialing](/source/Ten-digit_dialing) by October 24, 2021.[1] ## Service area - [Alhambra](/source/Alhambra%2C_California) (small portion in [NPA 213/323](/source/Area_codes_213_and_323)) - [Altadena](/source/Altadena%2C_California) - [Arcadia](/source/Arcadia%2C_California) - [Avocado Heights](/source/Avocado_Heights%2C_California) - [Azusa](/source/Azusa%2C_California) - [Baldwin Park](/source/Baldwin_Park%2C_California) - [Bassett](/source/Bassett%2C_California) - [Bradbury](/source/Bradbury%2C_California) - [Charter Oak](/source/Charter_Oak%2C_California) - [Citrus](/source/Citrus%2C_California) - [Covina](/source/Covina%2C_California) - [Duarte](/source/Duarte%2C_California) - [East Pasadena](/source/East_Pasadena%2C_California) - [East San Gabriel](/source/East_San_Gabriel%2C_California) - [El Monte](/source/El_Monte%2C_California) - [Glendora](/source/Glendora%2C_California) (small part in [909](/source/Area_code_909)) - [Hacienda Heights](/source/Hacienda_Heights%2C_California) (small part in [562](/source/Area_code_562)) - [Industry](/source/Industry%2C_California) (small part in [562](/source/Area_code_562) and [909](/source/Area_code_909)) - [Irwindale](/source/Irwindale%2C_California) - [La Puente](/source/La_Puente%2C_California) - [Mayflower Village](/source/Mayflower_Village%2C_California) - [Monrovia](/source/Monrovia%2C_California) - [Monterey Park](/source/Monterey_Park%2C_California) (also in [213/323](/source/Area_codes_213_and_323)) - [North El Monte](/source/North_El_Monte%2C_California) - [Pasadena](/source/Pasadena%2C_California) (small part in [213/323](/source/Area_codes_213_and_323)) - [Rosemead](/source/Rosemead%2C_California) (small part in the [213/323 area code](/source/Area_codes_213_and_323)) - [Rowland Heights](/source/Rowland_Heights%2C_California) (also in the [NPA 909](/source/Area_code_909) and small part in [NPA 562](/source/Area_code_562)) - [San Gabriel](/source/San_Gabriel%2C_California) - [San Marino](/source/San_Marino%2C_California) - [Sierra Madre](/source/Sierra_Madre%2C_California) - [South El Monte](/source/South_El_Monte%2C_California) - [South Pasadena](/source/South_Pasadena%2C_California) (also in [NPA 213/323](/source/Area_codes_213_and_323)) - [South San Gabriel](/source/South_San_Gabriel%2C_California) - [South San Jose Hills](/source/South_San_Jose_Hills%2C_California) - [Temple City](/source/Temple_City%2C_California) - [Valinda](/source/Valinda%2C_California) - [Vincent](/source/Vincent%2C_California) - [Walnut](/source/Walnut%2C_California) (mostly in [NPA 909](/source/Area_code_909)) - [West Covina](/source/West_Covina%2C_California) (small part in the [909 area code](/source/Area_code_909)) - [West Puente Valley](/source/West_Puente_Valley%2C_California) ## See also - [List of California area codes](/source/List_of_California_area_codes) - [List of North American Numbering Plan area codes](/source/List_of_North_American_Numbering_Plan_area_codes) ## References 1. **[^](#cite_ref-pl556_1-0)** ["Transition to 10-digit dialing (for 988 as 3-digit access to National Suicide Prevention Hotline)"](https://nationalnanpa.com/pdf/PL_556.pdf) (PDF).
