PINNACLE prefixes in area code 501

NANPA records 5 assigned NXX blocks to rate center PINNACLE in area code 501, 0.8% of the 631 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 WINDSTREAM COMMUNICATIONS, INC. - AR (2), LEVEL 3 TELECOM OF ARKANSAS, LLC - AR (1), LEVEL 3 COMMUNICATIONS, LLC - AR (1). 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
