SOMERSET prefixes in area code 606

NANPA records 24 assigned NXX blocks to rate center SOMERSET in area code 606, 3.8% 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. 11 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - KY (6), WINDSTREAM KENTUCKY EAST, INC. - LEXINGTON (6), NEW CINGULAR WIRELESS PCS, LLC - GA (2). The earliest assignment on record here is 2001-08-21 and the most recent 2024-10-31. 14 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 220, 534, 582, 715 – overlay codes cover the same geography, so a rate center is served by all of them.
