SCOTTVILLE prefixes in area code 231

NANPA records 5 assigned NXX blocks to rate center SCOTTVILLE in area code 231, 0.9% of the 572 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. 5 holders hold those blocks, the largest being INTERACTIVE SERVICES NETWORK, INC. (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1), MICHIGAN BELL TEL CO (1). The earliest assignment on record here is 2001-06-18 and the most recent 2002-08-27. 4 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 217, 336, 447 – overlay codes cover the same geography, so a rate center is served by all of them.
