CARMEL prefixes in area code 317

NANPA records 43 assigned NXX blocks to rate center CARMEL in area code 317, 5.5% 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 (22), PAETEC ITEL, LLC (4), LEVEL 3 TELECOM OF INDIANA, LP - IN (4). The earliest assignment on record here is 2005-05-27 and the most recent 2017-04-05. 25 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 329, 463, 831, 845 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
