CLOSTER prefixes in area code 201
NANPA records 13 assigned NXX blocks to rate center CLOSTER in area code 201, 1.7% 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. 8 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2), TELEPORT COMMUNICATIONS AMERICA, LLC - NJ (2). The earliest assignment on record here is 2007-09-10 and the most recent 2023-08-16. 9 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.
