HARRIETTA prefixes in area code 231
NANPA records 3 assigned NXX blocks to rate center HARRIETTA in area code 231, 0.5% of the 572 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. 3 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (1), PEERLESS NETWORK OF MICHIGAN, LLC - MI (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2015-12-01 and the most recent 2022-02-22. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
