KIRKWOOD prefixes in area code 314
NANPA records 90 assigned NXX blocks to rate center KIRKWOOD in area code 314, 11.5% of the 783 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. 13 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (55), SOUTHWESTERN BELL (8), T-MOBILE USA, INC. (4). The earliest assignment on record here is 2002-03-19 and the most recent 2026-05-21. 51 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 223, 309, 557, 717 – overlay codes cover the same geography, so a rate center is served by all of them.
