CLIFFORD prefixes in area code 989

NANPA records 4 assigned NXX blocks to rate center CLIFFORD in area code 989, 0.6% of the 723 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. 4 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (1), INTERACTIVE SERVICES NETWORK, INC. (1), 123.NET, LLC (1). The earliest assignment on record here is 2001-11-02 and the most recent 2002-08-12. 2 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 code 570 – overlay codes cover the same geography, so a rate center is served by all of them.
