History of Area Code 626
Area code 626 was created through a geographic split of 818. It entered service in June 1997, giving the San Gabriel Valley a separate telephone identity while other areas continued using 818.
The split became necessary because population growth, business expansion, mobile phones, fax machines, and other services were reducing available 818 numbers. Existing telephone numbers changed during the split, and callers received a transition period.
Before 818 existed, much of the region used 213. The history of 626 therefore reflects the long-term growth of metropolitan Los Angeles.
Time Zone of Area Code 626
Area code 626 follows the Pacific Time Zone. It observes Pacific Standard Time during standard time and Pacific Daylight Time when daylight saving time is active. California changes clocks seasonally under current daylight saving rules.
The region is generally three hours behind Eastern Time. Callers should check the local time before contacting residents, schools, offices, or businesses.

For businesses, a 626 number creates a recognised local connection and helps customers identify an organisation serving eastern Los Angeles County.
Is Area Code 626 Running Out?
Available 626 prefixes are gradually declining. The latest official forecast projects possible exhaustion in the first quarter of 2030, although the date may change.
California regulators are considering an overlay for the same region. No new overlay is currently in service, and existing 626 numbers remain unchanged. Ten-digit dialling is already required.
How to Dial Area Code 626
Callers should include the area code when saving or dialling a 626 number. Use these methods:
- From a California landline: Dial 1 + 626 + the seven-digit telephone number.
- From a mobile phone: Dial 626 + the seven-digit number, or 1 + 626 + the number.
- From outside the United States: Dial +1 + 626 + the seven-digit number.
- For emergency and approved short services: Dial numbers such as 911 or 811 directly.
Save the complete area code and number in contacts, websites, business records, alarms, and automatic dialling equipment.
