WEBSTER CY prefixes in area code 515

NANPA records 7 assigned NXX blocks to rate center WEBSTER CY in area code 515, 1.2% of the 578 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. 7 holders hold those blocks, the largest being T-MOBILE USA, INC. (1), UNITED STATES CELLULAR - IA (1), PREMIER COMMUNICATIONS, INC. - IA (1). The earliest assignment on record here is 2001-08-02 and the most recent 2021-09-28. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
