YALE prefixes in area code 810

NANPA records 5 assigned NXX blocks to rate center YALE in area code 810, 1.0% of the 509 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. 4 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (2), FRONTIER NORTH, INC. - MI (1), TELEPORT COMMUNICATIONS AMERICA, LLC - MI (1). The earliest assignment on record here is 2001-04-20 and the most recent 2002-05-23. 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 360, 539, 641, 918 – overlay codes cover the same geography, so a rate center is served by all of them.
