LEONIA prefixes in area code 201

NANPA records 19 assigned NXX blocks to rate center LEONIA in area code 201, 2.4% 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. (9), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3), LEVEL 3 COMMUNICATIONS, LLC - NJ (2). The earliest assignment on record here is 2001-02-15 and the most recent 2001-05-18. 11 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.
