BLACKSHEAR prefixes in area code 912

NANPA records 6 assigned NXX blocks to rate center BLACKSHEAR in area code 912, 0.8% of the 731 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. 6 holders hold those blocks, the largest being SOUTHERN COMMUNICATIONS SERVICES, INC. (1), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (1), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2001-06-26 and the most recent 2022-02-18. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
