MONTEZUMA prefixes in area code 765

NANPA records 3 assigned NXX blocks to rate center MONTEZUMA in area code 765, 0.4% 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. 3 holders hold those blocks, the largest being INDIANA BELL TEL CO INC (1), TELEPORT COMMUNICATIONS AMERICA, LLC - IN (1), BANDWIDTH.COM CLEC, LLC - IN (1). The earliest assignment on record here is 2020-07-17 and the most recent 2020-07-17. 3 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 478, 620, 641 – overlay codes cover the same geography, so a rate center is served by all of them.
