LA GRANGE prefixes in area code 464

NANPA records 19 assigned NXX blocks to rate center LA GRANGE in area code 464, 17.0% of the 112 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (15), T-MOBILE USA, INC. (1), ONVOY, LLC (1). The earliest assignment on record here is 2022-01-11 and the most recent 2026-09-09. 19 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 252, 307, 312, 502 – overlay codes cover the same geography, so a rate center is served by all of them.
