ROBY prefixes in area code 325
NANPA records 3 assigned NXX blocks to rate center ROBY 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 IP HORIZON LLC (1), ONVOY, LLC - TX (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2018-05-30 and the most recent 2025-02-05. 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 417 – overlay codes cover the same geography, so a rate center is served by all of them.
