TURLOCK prefixes in area code 209

NANPA records 31 assigned NXX blocks to rate center TURLOCK in area code 209, 4.0% of the 784 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 11 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (9), PACIFIC BELL (7), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (5). The earliest assignment on record here is 2001-07-16 and the most recent 2022-06-08. 22 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 350 – overlay codes cover the same geography, so a rate center is served by all of them.
