BENHAMLNCH prefixes in area code 606

NANPA records 3 assigned NXX blocks to rate center BENHAMLNCH in area code 606, 0.5% 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. 3 holders hold those blocks, the largest being ONVOY, LLC - KY (1), NEW CINGULAR WIRELESS PCS, LLC - GA (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). The earliest assignment on record here is 2002-06-05 and the most recent 2021-06-04. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
