GRESHAM prefixes in area code 971
NANPA records 10 assigned NXX blocks to rate center GRESHAM in area code 971, 2.3% of the 444 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. 6 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - OR (3), NEW CINGULAR WIRELESS PCS, LLC (3), CENTURYLINK COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2013-04-24 and the most recent 2026-03-13. 10 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 402, 503, 715 – overlay codes cover the same geography, so a rate center is served by all of them.
