Area code 530

About area code 530

Area code 530 is a geographic area code in California, in service since November 1, 1997, according to the North American Numbering Plan Administrator (NANPA). It is an overlay: 530 and 837 cover the same territory, so neighbors on the same street can have different area codes. It is in the Pacific time zone. The places with the most assigned exchanges include Chico, Redding, Marysville, Davis, and Woodland. By population, its largest named places are Chico, Redding, Davis, Woodland, and South Lake Tahoe.

Ten-digit and seven-digit dialing in 530

According to NANPA's dialing-plan data, local calls within 530 are dialed as 1 plus ten digits and toll calls as 1 plus ten digits. Ten-digit local dialing means the area code is part of how customers save and recognize your number, so print it in full everywhere.

Carriers with 530 numbers

56 carriers hold the 782 central office codes assigned in 530. Pacific Bell has the most, with 181 (23%). 642 of the codes (82%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. Numbers can move between carriers through porting, so a code's holder tells you where the block started, not where every number lives now.

Local calling areas in 530

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 530 has codes in 131 rate centers. The table lists the rate centers with the most codes, with the matching Census place where the abbreviation could be matched.

They are billed from prepaid AI minutes at $0.25 per minute, identify themselves as AI, and may only place outbound calls to people who consented, between 8am and 9pm.
