MADISON prefixes in area code 973
NANPA records 25 assigned NXX blocks to rate center MADISON in area code 973, 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. 9 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (14), LEVEL 3 COMMUNICATIONS, LLC - NJ (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2). 14 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 codes 203, 207, 256, 304 – overlay codes cover the same geography, so a rate center is served by all of them.
