COLUMBIAVL prefixes in area code 810

NANPA records 4 assigned NXX blocks to rate center COLUMBIAVL in area code 810, 0.8% 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 TON80 COMMUNICATIONS, LLC (1), PEERLESS NETWORK OF MICHIGAN, LLC - MI (1), TELEPORT COMMUNICATIONS AMERICA, LLC - MI (1). The earliest assignment on record here is 2014-04-14 and the most recent 2022-02-18. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
