FREEBURN prefixes in area code 606

NANPA records 7 assigned NXX blocks to rate center FREEBURN in area code 606, 1.1% of the 639 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 NEW CINGULAR WIRELESS PCS, LLC - GA (2), AT&T ENTERPRISES, LLC (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2002-06-05 and the most recent 2024-04-18. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
