MEMPHIS prefixes in area code 810

NANPA records 5 assigned NXX blocks to rate center MEMPHIS 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. 5 holders hold those blocks, the largest being ONVOY, LLCV - MI (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (1), FRONTIER NORTH, INC. - MI (1). The earliest assignment on record here is 2002-01-16 and the most recent 2020-11-03. 4 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 660, 662, 806, 901 – overlay codes cover the same geography, so a rate center is served by all of them.
