ELKADER prefixes in area code 563

NANPA records 3 assigned NXX blocks to rate center ELKADER in area code 563, 0.8% of the 388 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. 3 holders hold those blocks, the largest being ALPINE COMMUNICATIONS, L.C. (1), TON80 COMMUNICATIONS, LLC (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2022-01-13 and the most recent 2022-01-13. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
