Did you just get your WA license renewed like I did? Some bad news, after 10/2020 WA licenses will no longer be accepted as federal identification, meaning you won't be able to fly out of the state of WA without an enhanced ID or US passport.
According to KOMO news, "starting on Sept. 4, 2018, all driver's license and ID cards issued will receive new driver license numbers."
Geez, that isn't last minute or anything.

In September license numbers will be changing, so I highly suggest that you maybe look into getting a passport. I think I may finally breakdown and get one now, too.
