PLEASANTVL prefixes in area code 640

NANPA records 14 assigned NXX blocks to rate center PLEASANTVL in area code 640, 10.4% of the 134 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. 6 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (7), OMNIPOINT COMMUNICATIONS ENTERPRISES, LP (3), IP HORIZON LLC (1). The earliest assignment on record here is 2021-03-02 and the most recent 2026-09-10. 14 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 220, 515, 609, 715 – overlay codes cover the same geography, so a rate center is served by all of them.
