A new dialing process is coming if you have a 510 area code.
By on May 29, 2019
Next month telephone customers in the 510 area code must dial 1 plus the area code and the number to make any call to the 510 or the new 341 area code. The new dialing procedure starts June 22 and paves the way for the addition of the 341 area code to the region served by the 510 code. The price of the calls will not change.
