ADEL prefixes in area code 515

NANPA records 7 assigned NXX blocks to rate center ADEL 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. 4 holders hold those blocks, the largest being UNITED STATES CELLULAR - IA (3), QWEST CORPORATION (2), AUREON COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2008-11-14 and the most recent 2025-09-19. 7 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 code 229 – overlay codes cover the same geography, so a rate center is served by all of them.
