MANTZVILLE prefixes in area code 272

NANPA records 3 assigned NXX blocks to rate center MANTZVILLE in area code 272, 0.9% of the 337 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. 2 holders hold those blocks, the largest being TELNYX LLC (2), IP HORIZON LLC (1). The earliest assignment on record here is 2021-04-24 and the most recent 2023-12-07. 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 code 570 – overlay codes cover the same geography, so a rate center is served by all of them.
