STCLAIRSVL prefixes in area code 740

NANPA records 17 assigned NXX blocks to rate center STCLAIRSVL in area code 740, 2.2% of the 786 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. 8 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (6), OHIO BELL TEL CO (4), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2007-06-07 and the most recent 2010-06-23. 14 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
