GRAND IS prefixes in area code 716

NANPA records 7 assigned NXX blocks to rate center GRAND IS in area code 716, 0.9% 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 VERIZON NEW YORK, INC. (3), LEVEL 3 COMMUNICATIONS, LLC - NY (1), CENTURYLINK COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2015-05-19 and the most recent 2024-05-09. 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 308, 503, 971 – overlay codes cover the same geography, so a rate center is served by all of them.
