OZONA prefixes in area code 325
NANPA records 7 assigned NXX blocks to rate center OZONA in area code 325, 1.7% of the 408 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. 6 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (2), ONVOY, LLC - TX (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - TX (1). The earliest assignment on record here is 2016-11-28 and the most recent 2026-03-24. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
