EDINBURGH prefixes in area code 812

NANPA records 3 assigned NXX blocks to rate center EDINBURGH in area code 812, 0.4% 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. 3 holders hold those blocks, the largest being INDIANA BELL TEL CO INC (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1), LEVEL 3 COMMUNICATIONS, LLC - IN (1). The earliest assignment on record here is 2002-08-05 and the most recent 2017-06-30. 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 code 930 – overlay codes cover the same geography, so a rate center is served by all of them.
