CLIFFSIDE prefixes in area code 201

NANPA records 25 assigned NXX blocks to rate center CLIFFSIDE in area code 201, 3.2% 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. (8), OMNIPOINT COMMUNICATIONS, INC. - NJ (5), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3). The earliest assignment on record here is 2001-02-26 and the most recent 2011-03-29. 15 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.
