STFRD-SNDY prefixes in area code 971
NANPA records 8 assigned NXX blocks to rate center STFRD-SNDY in area code 971, 1.8% 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (3), ONVOY, LLC - OR (2), ELECTRIC LIGHTWAVE LLC DBA ALLSTREAM (1). The earliest assignment on record here is 2001-06-13 and the most recent 2026-06-01. 8 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 503 – overlay codes cover the same geography, so a rate center is served by all of them.
