DOUBLE SPG prefixes in area code 205

NANPA records 4 assigned NXX blocks to rate center DOUBLE SPG in area code 205, 0.5% 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. 3 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - GA (2), BRIGHTSPEED OF ALABAMA, LLC - NORTHERN (1), BANDWIDTH.COM CLEC, LLC - AL (1). The earliest assignment on record here is 2006-12-20 and the most recent 2020-05-12. 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 code 659 – overlay codes cover the same geography, so a rate center is served by all of them.
