CLAFLIN prefixes in area code 620

NANPA records 3 assigned NXX blocks to rate center CLAFLIN in area code 620, 0.4% of the 705 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 UNITED TEL OF EASTERN KANSAS DBA CENTURYLINK (1), H & B CABLE SERVICE, INC. - KS (1), NEX-TECH WIRELESS, LLC (1). The earliest assignment on record here is 2004-08-19 and the most recent 2005-09-14. 1 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
