The 628 region comprises parts of San Francisco County, most of Marin County, and a portion of San Mateo County in California. San Francisco, the largest city in this area, is one of the most densely populated urban centers in the United States and a key hub for technology, finance, and culture. According to Data USA, the city is home to a total population of 836,321 and an employed population of 484,966.
Economically, the region maintains a median household income of approximately $126,000 and a per capita income of around $77,000, reflecting its position as one of the most affluent metropolitan areas in the nation.

The region operates on UTC+8 during Pacific Standard Time (PST) and UTC+7 during Pacific Daylight Time (PDT), with daylight saving adjustments occurring in March and November each year.
This time zone offers a strategic advantage for businesses, as it aligns with major U.S. economic hubs such as San Francisco, Los Angeles, Seattle, and Las Vegas.

For residents of the 628 region, seeing a local number signals that a business is genuinely part of their community. Calls from a recognizable 628 number are far more likely to be answered and trusted, while out-of-state or unfamiliar numbers are often ignored or flagged as spam.
