The California Public Utilities Commission (CPUC) recognized that the demand for new phone numbers in the 530 area code was rapidly increasing. The existing supply of prefixes within the 530 area code was projected to run out by September 2025. To address this impending shortage and ensure continued service, the CPUC approved the implementation of a new area code.

This means that area code 837 will cover the same geographic region as area code 530. All current 530 area code customers will retain their existing numbers and area code. The new 837 area code will be assigned to new phone number requests in the region once the 530 prefixes are exhausted.
