Best private app
Ghost is the best app by far I have come across keeping my real identity and information private. This app is great and it would be a total loss if taking away! I give 10 stars ! Have been using…

Why choose a San Carlos virtual phone number?
East Bay commute overlap
Fremont and Hayward sit about 25 miles east across the bay, close enough that plenty of people who work in San Carlos commute from there. A 650 number gives local contacts a familiar area code, whatever code your existing phone carries.
San Mateo's shared code
San Mateo, San Carlos's closest neighbor, shares the 650 area code. A Ghost number picked here reads the same as a San Mateo contact to anyone nearby, useful when you're posting to local groups or meeting someone new.
Sacramento ties on 916
If you've got family or a lease waiting in Sacramento, grab a 916 number alongside your San Carlos line. It keeps calls to that city looking familiar while your 650 number handles life on the Peninsula.
San Jose connections on 408
San Jose runs on the 408 code. For anyone splitting time between there and San Carlos for work or family, a second Ghost number in 408 keeps those calls from looking out of place.
Oakland's 510 reach
Oakland's 510 code shows up constantly for anyone with ties across the bay. Carrying a 510 number alongside your San Carlos 650 line means a bay area contact doesn't suddenly ring a stranger's number.

Local economy
Why do business in San Carlos?
San Carlos sits on the Peninsula between San Francisco and San Jose, in a stretch of the Bay Area built on technology and biotech work.
Technology
San Carlos and its Peninsula neighbors, including San Mateo and Mountain View, sit inside one of the country's densest tech corridors, and many residents work for firms scattered between San Francisco and San Jose.
Life sciences and biotech
The Peninsula, running from San Carlos toward San Mateo and San Francisco, carries a cluster of biotech and life sciences companies, and it's common for residents to work in that field.
Retail and small business
With a population of 29,403, San Carlos supports a Main Street mix of independent shops and services that residents rely on day to day.
About San Carlos

Population
29,403
San Carlos sits inside the 650 area code, shared with neighboring San Mateo. Residents also cross paths with 916 numbers from Sacramento, 510 from Oakland, 415 and 628 from San Francisco, and 408 from San Jose as family, friends, and coworkers move around the Bay Area and beyond.
All of these codes run on Pacific time, so a 650, 415, 628, 510, 408, or 916 number keeps the same clock as San Carlos. 415 and 628 are overlay codes covering the same San Francisco calling area, and 510 and 408 work the same way for Oakland and San Jose.
Like much of the Bay Area, San Carlos households field a steady mix of spam calls and robocalls tied to shared area codes. Keeping a separate Ghost number for selling, dating, or casual contacts keeps that noise off the line your close friends and family use.

Frequently asked questions
How fast can I get a San Carlos phone number?
You can pick a 650 number, or choose 916, 510, 415, 628, or 408 if that fits better, and start calling and texting in minutes.
Can I choose an area code besides 650?
Yes. Ghost lets you pick from 650, 916, 510, 415, 628, and 408, along with other codes across the country, so your number can match wherever you actually need it to look local.
Will texts and calls from my Ghost number look different from my personal number?
No. Calls and texts send and receive like any other number, they just come from a separate line you control, so you can keep your San Carlos number for one purpose and your personal number for everything else.
