CUMMING prefixes in area code 678

NANPA records 15 assigned NXX blocks to rate center CUMMING in area code 678, 1.9% 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. 8 holders hold those blocks, the largest being PAETEC ITEL, LLC (4), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (3), METROPCS, INC. (3). The earliest assignment on record here is 2001-02-27 and the most recent 2008-11-13. 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 470, 770, 943 – overlay codes cover the same geography, so a rate center is served by all of them.
