MAURICEVL prefixes in area code 409

NANPA records 5 assigned NXX blocks to rate center MAURICEVL in area code 409, 1.2% of the 434 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. 4 holders hold those blocks, the largest being ONVOY, LLC - TX (2), LEVEL 3 COMMUNICATIONS, LLC - TX (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2021-05-10 and the most recent 2024-03-14. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
