MONTRSE prefixes in area code 216

NANPA records 33 assigned NXX blocks to rate center MONTRSE in area code 216, 5.4% of the 613 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. 13 holders hold those blocks, the largest being OHIO BELL TEL CO (9), ONVOY, LLC - OH (5), LEVEL 3 COMMUNICATIONS, LLC - OH (4). The earliest assignment on record here is 2001-04-03 and the most recent 2026-08-26. 26 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
