WINFIELD prefixes in area code 205

NANPA records 5 assigned NXX blocks to rate center WINFIELD in area code 205, 0.6% of the 785 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. 4 holders hold those blocks, the largest being BRIGHTSPEED OF ALABAMA, LLC - NORTHERN (2), CENTURYLINK COMMUNICATIONS, LLC (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AL (1). The earliest assignment on record here is 2003-01-30 and the most recent 2008-03-17. 3 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 304, 319, 430, 620 – overlay codes cover the same geography, so a rate center is served by all of them.
