WALHALLA prefixes in area code 864

NANPA records 6 assigned NXX blocks to rate center WALHALLA in area code 864, 0.8% 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. 5 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (2), ONVOY, LLC - SC (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2005-12-16 and the most recent 2024-11-07. 6 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 701 – overlay codes cover the same geography, so a rate center is served by all of them.
