DUBUQUE prefixes in area code 563
NANPA records 36 assigned NXX blocks to rate center DUBUQUE in area code 563, 9.3% 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. 10 holders hold those blocks, the largest being QWEST CORPORATION (10), UNITED STATES CELLULAR - IA (7), T-MOBILE USA, INC. (4). The earliest assignment on record here is 2001-03-04 and the most recent 2023-08-03. 25 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
