ATTICA prefixes in area code 765

NANPA records 7 assigned NXX blocks to rate center ATTICA in area code 765, 1.0% of the 725 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. 6 holders hold those blocks, the largest being INDIANA BELL TEL CO INC (2), LEVEL 3 COMMUNICATIONS, LLC - IN (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2002-02-13 and the most recent 2021-11-16. 7 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 419, 567, 585, 620 – overlay codes cover the same geography, so a rate center is served by all of them.
