CLARE prefixes in area code 989

NANPA records 11 assigned NXX blocks to rate center CLARE in area code 989, 1.5% 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. 7 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (3), MICHIGAN BELL TEL CO (2), AMERICAN MESSAGING SERVICES, LLC (2). The earliest assignment on record here is 2001-10-17 and the most recent 2010-02-03. 6 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 515 – overlay codes cover the same geography, so a rate center is served by all of them.
