MIDDLESBO prefixes in area code 606

NANPA records 14 assigned NXX blocks to rate center MIDDLESBO in area code 606, 2.2% 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. 8 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (3), NEW CINGULAR WIRELESS PCS, LLC - GA (3), EAST KENTUCKY NETWRK, LLC DBA APPALACHIAN WIRELESS (2). The earliest assignment on record here is 2001-02-15 and the most recent 2022-09-20. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
