CHAPPAQUA prefixes in area code 914

NANPA records 12 assigned NXX blocks to rate center CHAPPAQUA in area code 914, 1.7% of the 704 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. 11 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (2), YMAX COMMUNICATIONS CORP. - NY (1), BANDWIDTH.COM CLEC, LLC - NY (1). The earliest assignment on record here is 2005-09-16 and the most recent 2023-10-17. 11 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
