BELLEPLAIN prefixes in area code 319

NANPA records 3 assigned NXX blocks to rate center BELLEPLAIN in area code 319, 0.5% of the 565 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. - NORTH (2), SHELLSBURG CABLEVISION, INC. (1). The earliest assignment on record here is 2016-07-28 and the most recent 2016-07-28. 2 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 620 – overlay codes cover the same geography, so a rate center is served by all of them.
