MADISON prefixes in area code 256
NANPA records 15 assigned NXX blocks to rate center MADISON in area code 256, 1.9% 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. 8 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (5), PAETEC ITEL, LLC (3), NEW CINGULAR WIRELESS PCS, LLC - GA (2). The earliest assignment on record here is 2001-01-29 and the most recent 2019-08-08. 10 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, 304, 315 – overlay codes cover the same geography, so a rate center is served by all of them.
