I tried to pick up a smoking deal on a shotgun today at a Walmart in rural OR. They would not let me fill out the form 4473 because my residential zip code is not on my license. Oregon DMV only puts zip code for mailing address on the license when you have both addresses on your license. I have bought many firearms and this is the first time the zip code issue has come up. Has anybody else dealt with this problem. How did you remedy it?
