MADISON prefixes in area code 850
NANPA records 8 assigned NXX blocks to rate center MADISON in area code 850, 1.0% of the 786 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. 6 holders hold those blocks, the largest being CENTURYLINK OF FLORIDA, INC. (CENTRAL) (3), NEW CINGULAR WIRELESS PCS, LLC - GA (1), TELEPORT COMMUNICATIONS AMERICA, LLC - FL (1). The earliest assignment on record here is 2001-03-16 and the most recent 2009-11-10. 8 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.
