CLARENCCTR prefixes in area code 716

NANPA records 5 assigned NXX blocks to rate center CLARENCCTR in area code 716, 0.7% of the 768 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. 5 holders hold those blocks, the largest being PAETEC ITEL, LLC (1), BANDWIDTH.COM CLEC, LLC - NY (1), LEVEL 3 COMMUNICATIONS, LLC - NY (1). The earliest assignment on record here is 2010-06-17 and the most recent 2021-10-06. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
