USDA inspection station Seattle WA

Hi everyone!

Has anybody dealt with USDA plant and seeds inspection stations? I got my seeds shipped to the one in Washington Seattle, 835 South 192nd Street, SeaTac WA. They arrived today, but Seller and I forgot to provide a shipping label to my address inside the package.

So I guess I have to pick them up? Or bring them a shipping label for whenever they are ready to ship the package.

I might be stupid but I can’t find any contact number. Does anybody know if I can just walk in there or I need an appointment? If anybody has a phone number I would be so grateful.

Thanks in advance.
