OAK GROVE prefixes in area code 270

NANPA records 12 assigned NXX blocks to rate center OAK GROVE in area code 270, 1.6% of the 769 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. 5 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (8), ONVOY, LLC - KY (1), LEVEL 3 COMMUNICATIONS, LLC - KY (1). The earliest assignment on record here is 2005-01-12 and the most recent 2019-03-12. 9 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 318, 364, 615, 629 – overlay codes cover the same geography, so a rate center is served by all of them.
