History of 510 Area Code

510 area code was introduced in 1991 to cover the eastern portion of the Bay Area, California, including Oakland. Before its introduction, the entire region was served by the area code 415. However, due to the rapid population growth, 415 alone was becoming sort in supply to serve the region. For this reason, area code 510 was created.

With the growing demand for new numbers, the 510 also went through several changes in the following years. In 1998, this area code was split to create the 925 area code, taking over the eastern portion of the 510 region. Likewise, in 2019, the 341 area code was introduced as an overlay to serve the same region in California.
