MADRID prefixes in area code 315

NANPA records 10 assigned NXX blocks to rate center MADRID in area code 315, 1.3% of the 781 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. 5 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NY (3), CONTACT COMMUNICATIONS, INC. (2), VERIZON NEW YORK, INC. (2). 6 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 308, 515, 680 – overlay codes cover the same geography, so a rate center is served by all of them.
