History of Area Code 530
Area code 530 began service on November 1, 1997, after a split from area code 916. The split assigned northern and northeastern communities to 530, while the Sacramento area continued using 916.
Area code 837 was later approved as an overlay for the 530 region because the supply of available telephone numbers was nearing exhaustion. New 837 numbers became available on January 31, 2025, while customers with existing 530 numbers kept their numbers.
