DELPHI prefixes in area code 765

NANPA records 5 assigned NXX blocks to rate center DELPHI in area code 765, 0.7% 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. 5 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (1), ONVOY, LLC - IN (1), FRONTIER MIDSTATES, INC. - IN (1). The earliest assignment on record here is 2004-10-04 and the most recent 2022-01-07. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
