FISHERS prefixes in area code 317

NANPA records 34 assigned NXX blocks to rate center FISHERS in area code 317, 4.3% 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. 9 holders hold those blocks, the largest being INDIANA BELL TEL CO INC (19), PAETEC ITEL, LLC (3), COMCAST IP PHONE, LLC (2). The earliest assignment on record here is 2001-06-15 and the most recent 2017-12-07. 20 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 463 – overlay codes cover the same geography, so a rate center is served by all of them.
