HAMILTON prefixes in area code 205

NANPA records 5 assigned NXX blocks to rate center HAMILTON 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), POWERTEL BIRMINGHAM LICENSES, INC. (1), BANDWIDTH.COM CLEC, LLC - AL (1). The earliest assignment on record here is 2004-11-05 and the most recent 2004-11-05. 4 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 217, 252, 254, 260 – overlay codes cover the same geography, so a rate center is served by all of them.
