SANBORN prefixes in area code 716

NANPA records 4 assigned NXX blocks to rate center SANBORN in area code 716, 0.5% 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 CITIZENS TELECOMM CO OF NY DBA FRONTIER COMM OF NY (2), TWC IP ENABLED SERVICES, LLC (1), BANDWIDTH.COM CLEC, LLC - NY (1). The earliest assignment on record here is 2006-12-18 and the most recent 2019-03-29. 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 507, 701, 712 – overlay codes cover the same geography, so a rate center is served by all of them.
