LYMAN prefixes in area code 864

NANPA records 12 assigned NXX blocks to rate center LYMAN in area code 864, 1.5% of the 784 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 BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (4), PAETEC ITEL, LLC (3), COMMIO, LLC (2). The earliest assignment on record here is 2002-02-11 and the most recent 2024-03-07. 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 307, 308 – overlay codes cover the same geography, so a rate center is served by all of them.
