COLEMAN prefixes in area code 325

NANPA records 3 assigned NXX blocks to rate center COLEMAN in area code 325, 0.7% 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. 3 holders hold those blocks, the largest being ONVOY SPECTRUM, LLC (1), FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2005-10-06 and the most recent 2021-07-27. 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 920, 989 – overlay codes cover the same geography, so a rate center is served by all of them.
