FRANKLIN prefixes in area code 317

NANPA records 12 assigned NXX blocks to rate center FRANKLIN in area code 317, 1.5% 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. 5 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (6), BRIGHTSPEED OF INDIANA, LLC (3), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2002-07-10 and the most recent 2024-05-28. 9 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 207, 217, 270, 304 – overlay codes cover the same geography, so a rate center is served by all of them.
