CLARENCE prefixes in area code 716

NANPA records 6 assigned NXX blocks to rate center CLARENCE in area code 716, 0.8% 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 ONVOY, LLC- NY (2), BANDWIDTH.COM CLEC, LLC - NY (1), LEVEL 3 COMMUNICATIONS, LLC - NY (1). The earliest assignment on record here is 2010-02-11 and the most recent 2023-07-14. 6 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 codes 563, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
