CALMAR prefixes in area code 563
NANPA records 3 assigned NXX blocks to rate center CALMAR 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 ONVOY SPECTRUM, LLC (1), QWEST CORPORATION (1), ONVOY, LLC - IA (1). The earliest assignment on record here is 2018-02-16 and the most recent 2021-06-21. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
