UNION prefixes in area code 864

NANPA records 13 assigned NXX blocks to rate center UNION in area code 864, 1.7% 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. 7 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (4), NEW CINGULAR WIRELESS PCS, LLC - GA (2), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2001-03-23 and the most recent 2023-07-20. 12 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 207, 269, 304, 360 – overlay codes cover the same geography, so a rate center is served by all of them.
