Great app
Love this app. It’s easy to set up and use. I really feel safer knowing that my real number isn’t being used when I have to enter a phone number online. Plus this app is transparent. They don’t hide anything…

Why choose a Hillsborough virtual phone number?
A 650 Number Feels Like San Mateo
650 is carried by many people in nearby San Mateo, so a Hillsborough number in that code reads as local to anyone across the county line, not just within town limits.
415 and 628 Open San Francisco Doors
If you deal with people or clients in San Francisco, a 415 or 628 number signals you're reachable in the city, without giving up your Hillsborough line.
510 Signals Oakland, Not a Cold Call
510 is common among callers based in Oakland. Using it for contacts there makes your call look familiar instead of like an outside number they'll ignore.
408 Speaks Sunnyvale and San Jose
For work or networking tied to Sunnyvale or San Jose, a 408 number fits the area code residents there already recognize, useful if you're job hunting or building contacts south of Hillsborough.
Daly City and Berkeley Round Out the Circle
Hillsborough sits inside a wider ring that includes Daly City, Berkeley, Fremont, and Hayward. A second number lets you keep separate lines for different corners of that circle without juggling phones.

About Hillsborough

Population

650 covers Hillsborough and San Mateo. San Francisco callers commonly carry 415 or 628. Sacramento is associated with 916, Oakland with 510, and San Jose with 408, so picking any of these can put you in step with people you regularly call across the wider Bay Area.
Hillsborough runs on Pacific Time, same as the rest of the region. 415 and 628 overlay the same San Francisco area, meaning both codes serve that one city rather than splitting it geographically, while 650 stands on its own for the San Mateo County side.
Residents in this part of California, like much of the state, report a steady stream of unwanted calls, including robocalls and scam or imposter callers pretending to be businesses or agencies. Keeping a second number for listings, dating profiles, or new contacts helps keep that traffic off your main line.
