ROOSEVELT prefixes in area code 435

NANPA records 5 assigned NXX blocks to rate center ROOSEVELT in area code 435, 1.0% of the 501 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 NEW CINGULAR WIRELESS PCS, LLC (2), UBTA-UBET COMMUNICATIONS, INC. DBA STRATA NETWORKS (2), UINTAH BASIN ELECTRONIC TELECOMMUNICATIONS (1). The earliest assignment on record here is 2008-02-25 and the most recent 2008-02-25. 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 218, 509, 580 – overlay codes cover the same geography, so a rate center is served by all of them.
