Effective 2 days ago, Oregon added a second area code (971), which will cover the eastern 2/3 of the state. Ads in the paper daily to start dialing 10 numbers for all local calls, to practice, and they will start enforcing it in January.
The DFW 214/972 thing was confusing at first, but I've never been in a hotel (usually stay somewhere in Irving/Las Colinas area) that made you use a different access for each one.
