RICHMNRNBG prefixes in area code 346

NANPA records 27 assigned NXX blocks to rate center RICHMNRNBG in area code 346, 3.6% of the 752 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. 8 holders hold those blocks, the largest being AERIAL COMMUNICATIONS, INC. (11), NEW CINGULAR WIRELESS PCS, LLC - IL (5), ONVOY, LLC - TX (3). The earliest assignment on record here is 2015-04-21 and the most recent 2026-08-21. 27 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 281, 713, 832 – overlay codes cover the same geography, so a rate center is served by all of them.
