CEDARGROVE prefixes in area code 731
NANPA records 4 assigned NXX blocks to rate center CEDARGROVE 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 LEVEL 3 COMMUNICATIONS, LLC - TN (1), ONVOY, LLC - TN (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2002-04-10 and the most recent 2025-06-30. 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 478, 920 – overlay codes cover the same geography, so a rate center is served by all of them.
