ANTIOCH prefixes in area code 925
NANPA records 67 assigned NXX blocks to rate center ANTIOCH in area code 925, 10.5% of the 640 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. 18 holders hold those blocks, the largest being T-MOBILE USA, INC. (16), PACIFIC BELL (12), NEW CINGULAR WIRELESS PCS, LLC (7). The earliest assignment on record here is 2001-07-17 and the most recent 2026-07-30. 48 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 224, 847, 864 – overlay codes cover the same geography, so a rate center is served by all of them.
