PLATTSBG prefixes in area code 518

NANPA records 31 assigned NXX blocks to rate center PLATTSBG in area code 518, 4.0% of the 775 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. 17 holders hold those blocks, the largest being VERIZON NEW YORK, INC. (5), NEW CINGULAR WIRELESS PCS, LLC - DC (4), PAETEC ITEL, LLC (3). The earliest assignment on record here is 2001-10-26 and the most recent 2016-12-05. 22 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
