How Do 510 Area Code Phone Numbers Work?

Area code 510 is registered under North American Numbering Plan (NANP). The 510 area code works like any other area code. In the 510 area code, calls are routed to the telecommunications infrastructure that manages phone numbers within that specific area. Here are some detailed ways on how it works.

1. Geographic Area

The 510 area code covers cities in the East Bay region of the San Francisco Bay Area, including Oakland, Berkeley, Fremont, Hayward, Richmond, and others. It covers services in two counties named Alameda and Contra Costa. However, it does not offer a service in certain parts of California, including Dublin, Livermore, Pleasanton, and Sunol.

2. Number Assignment

Local telecommunications providers assign area code 510 phone numbers. Phone numbers are allocated based on an individual’s or company’s needs and service agreement.

3. Dialing 

Callers must only dial the seven-digit phone number when making a local call within the 510 area code. For example, if you are making a call within Oakland, you should only dial 7 digits numbers like “555-1234” to make the call (555-1234 is a demo number). 

Likewise, callers must use the total ten-digit number to make a call from the 510 area code to another area code. For example, if you call someone in the 424 area code premises, you must dial 424-555-1234 to make the call. The phone number includes the area code and seven digits.

4. Number Portability

A number associated with the 510 area code can be “ported” from one carrier to another, which means that even though it is associated with the 510 area code, it can be used with any US carrier.
