Coverage
Where does the 628 area code apply?
The 628 area code covers the exact same territory as 415: the City and County of San Francisco, most of Marin County, and a small part of San Mateo County. It was introduced in 2015 as an all-services overlay, not a new geographic split.
Because 628 shares its footprint with the historic 415 code, every call in the region — including local ones — uses ten-digit dialing. A 628 number on Bloom AI cloud telephony gives your business the same San Francisco presence, wherever your team works from.

Phone number essentials
What to know about a virtual 628 number
628 serves San Francisco, most of Marin County and a slice of San Mateo County. It shares this area with the historic 415 code and operates in the Pacific Time Zone.
Number format
- +1 628 XXX XXXX internationally; 1 (628) XXX-XXXX within the United States.
Local dialing
- All calls in the 415/628 overlay use 1 plus the area code plus the seven-digit number, even for local calls.
Number type
- A geographic local number, distinct from a toll-free number such as 800 or 888.
Cloud operation
- Answer from connected devices without needing a physical office in San Francisco.
Same territory
628 or 415: which should you choose?
Both area codes cover the exact same San Francisco Bay Area territory. 628 is the newer overlay, introduced in 2015 once the 415 numbering pool needed relief; 415 is the original 1947 code. In practice, the choice mainly depends on which numbers are available when your line is activated.
Why 628
Why choose a 628 number for your business?
628 carries the same San Francisco identity as 415, drawn from a separate, newer numbering pool created specifically to keep the Bay Area supplied with local numbers. It gives a business a contact point associated with the city, even when its team works remotely.
And because every call runs through Bloom AI, your local number becomes a sales lever: every conversation is analyzed, summarized and turned into a next step.
