JACKSON prefixes in area code 209

NANPA records 13 assigned NXX blocks to rate center JACKSON in area code 209, 1.7% 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. 7 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (4), PACIFIC BELL (2), ONVOY, LLC - CA (2). The earliest assignment on record here is 2002-01-29 and the most recent 2022-03-10. 10 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 codes 225, 235, 251, 252 – overlay codes cover the same geography, so a rate center is served by all of them.
