LAGRANGE prefixes in area code 901

NANPA records 8 assigned NXX blocks to rate center LAGRANGE in area code 901, 1.3% of the 616 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 BANDWIDTH.COM CLEC, LLC - TN (3), TELNYX LLC (1), LEVEL 3 COMMUNICATIONS, LLC - TN (1). The earliest assignment on record here is 2012-05-22 and the most recent 2022-09-21. 8 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 260, 706, 762 – overlay codes cover the same geography, so a rate center is served by all of them.
