MATHIS prefixes in area code 361

NANPA records 8 assigned NXX blocks to rate center MATHIS in area code 361, 1.5% of the 538 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. 7 holders hold those blocks, the largest being ONVOY, LLC - TX (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1), COMMIO, LLC (1). The earliest assignment on record here is 2001-09-27 and the most recent 2023-10-04. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
