INDIAN RIV prefixes in area code 231
NANPA records 3 assigned NXX blocks to rate center INDIAN RIV 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), NEW CINGULAR WIRELESS PCS, LLC - IL (1), LEVEL 3 COMMUNICATIONS, LLC - MI (1). The earliest assignment on record here is 2001-06-18 and the most recent 2001-06-18. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
