RHINELANDR prefixes in area code 534

NANPA records 13 assigned NXX blocks to rate center RHINELANDR in area code 534, 13.3% of the 98 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. 2 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (12), ONVOY, LLC - WI (1). The earliest assignment on record here is 2023-05-05 and the most recent 2026-08-19. 13 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 715 – overlay codes cover the same geography, so a rate center is served by all of them.
