RANDOLPH prefixes in area code 716

NANPA records 3 assigned NXX blocks to rate center RANDOLPH in area code 716, 0.4% 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. 3 holders hold those blocks, the largest being TWC IP ENABLED SERVICES, LLC (1), WINDSTREAM NEW YORK, INC. - JAMESTOWN (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2012-01-30 and the most recent 2021-11-09. 3 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 339, 402, 435, 531 – overlay codes cover the same geography, so a rate center is served by all of them.
