GRAND JCT prefixes in area code 731

NANPA records 4 assigned NXX blocks to rate center GRAND JCT in area code 731, 1.0% of the 395 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. 4 holders hold those blocks, the largest being AT&T ENTERPRISES, LLC (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TN (1), LEVEL 3 COMMUNICATIONS, LLC - TN (1). The earliest assignment on record here is 2003-03-11 and the most recent 2010-01-06. 3 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 269, 515, 970 – overlay codes cover the same geography, so a rate center is served by all of them.
