DECKERVL prefixes in area code 810

NANPA records 5 assigned NXX blocks to rate center DECKERVL 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 NEW CINGULAR WIRELESS PCS, LLC - IL (1), FRONTIER NORTH, INC. - MI (1), 123.NET, LLC (1). The earliest assignment on record here is 2001-09-21 and the most recent 2001-12-28. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
