BLOOMFIELD prefixes in area code 812

NANPA records 5 assigned NXX blocks to rate center BLOOMFIELD in area code 812, 0.6% of the 785 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 (2), INDIANA BELL TEL CO INC (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2003-07-02 and the most recent 2009-12-07. 5 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 402, 406, 502, 573 – overlay codes cover the same geography, so a rate center is served by all of them.
