HLSCRSSRDS prefixes in area code 865

NANPA records 4 assigned NXX blocks to rate center HLSCRSSRDS in area code 865, 0.8% 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. 3 holders hold those blocks, the largest being TENNESSEE TEL. CO. (2), PAETEC ITEL, LLC (1), TELEPORT COMMUNICATIONS AMERICA, LLC - TN (1). The earliest assignment on record here is 2003-10-16 and the most recent 2003-10-16. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
