GATLINBURG prefixes in area code 865

NANPA records 7 assigned NXX blocks to rate center GATLINBURG in area code 865, 1.4% 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. 6 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), ONVOY, LLC - TN (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2006-05-24 and the most recent 2022-06-17. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
