RICHFIELD prefixes in area code 435
NANPA records 10 assigned NXX blocks to rate center RICHFIELD in area code 435, 2.0% 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. 8 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (2), QWEST CORPORATION (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - UT (1). The earliest assignment on record here is 2001-04-27 and the most recent 2022-02-24. 9 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 208, 223, 234, 330 – overlay codes cover the same geography, so a rate center is served by all of them.
