JEFFERSNCY prefixes in area code 865

NANPA records 6 assigned NXX blocks to rate center JEFFERSNCY in area code 865, 1.2% of the 506 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 SOUTH CENTRAL BELL TEL (2), PAETEC ITEL, LLC (1), CHARTER IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2009-11-12 and the most recent 2022-09-01. 5 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 235, 573 – overlay codes cover the same geography, so a rate center is served by all of them.
