RIDGEWOOD prefixes in area code 201

NANPA records 20 assigned NXX blocks to rate center RIDGEWOOD in area code 201, 2.6% of the 779 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. 10 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (9), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3), TELEPORT COMMUNICATIONS AMERICA, LLC - NJ (1). The earliest assignment on record here is 2001-04-10 and the most recent 2012-02-15. 12 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 code 551 – overlay codes cover the same geography, so a rate center is served by all of them.

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.
