Find any 628- phone number in California
The 628 area code is a part of the North American Numbering Plan. It is located in California, encompassing most of San Francisco and its northern suburbs. The plan is administered by the North American Numbering Plan Administrator (NANPA) and is responsible for establishing area codes in different regions across the US and Canada.
The 628 area code was implemented on April 19, 2015. It created a three-way split for the 415 area code, which until then had covered all of San Francisco and its neighboring areas. To accommodate the needs of the growing population in the area, the NANPA approved the creation of a new code to help manage the allocated demand for new phone numbers. This new code was designed with the purpose of easing the strain in the affected areas and preventing any future problems related to insufficient numbers.
