PORTLAND prefixes in area code 971
NANPA records 155 assigned NXX blocks to rate center PORTLAND in area code 971, 34.9% 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. 39 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OR (26), ONVOY, LLC - OR (20), T-MOBILE USA, INC. (20). The earliest assignment on record here is 2001-01-15 and the most recent 2026-10-13. 150 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 207, 260, 503, 517 – overlay codes cover the same geography, so a rate center is served by all of them.

Is PORTLAND a city?
It is a rate center – the unit NANPA allocates number blocks to. Its name is abbreviated to ten characters and is not necessarily a settlement: we print it as recorded rather than guess at the full name.
