CLARK prefixes in area code 605
NANPA records 3 assigned NXX blocks to rate center CLARK in area code 605, 0.4% of the 745 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. 2 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (2), INTERSTATE TELECOM COOP, INC. - SD (1). The earliest assignment on record here is 2003-08-07 and the most recent 2010-10-20. 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 codes 307, 573 – overlay codes cover the same geography, so a rate center is served by all of them.
