LODI prefixes in area code 209

NANPA records 36 assigned NXX blocks to rate center LODI in area code 209, 4.6% 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. 15 holders hold those blocks, the largest being PACIFIC BELL (9), T-MOBILE USA, INC. (5), NEW CINGULAR WIRELESS PCS, LLC (4). The earliest assignment on record here is 2001-05-17 and the most recent 2022-04-11. 26 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 234, 330, 350, 607 – overlay codes cover the same geography, so a rate center is served by all of them.
