LE CLAIRE prefixes in area code 563
NANPA records 3 assigned NXX blocks to rate center LE CLAIRE 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. 2 holders hold those blocks, the largest being WINDSTREAM IOWA COMMUNICATIONS, INC. - SYSTEMS (2), MCC TELEPHONY OF IOWA, LLC - IA (1). The earliest assignment on record here is 2010-03-09 and the most recent 2015-06-25. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
