I don't know what's going on. Two postcards that I sent out have been sent back to me this week. They are both from the same state, different recipients. There's nothing written on them as a reason to why they were returned. Like how some people write "return to sender." They have the barcode on them, so I'm assuming they went through the system. The one I think was sent out a month or so ago.

I'm just confused lol and am getting nervous about sending to this state now. Are there some areas where USPS is having problems or strikes? The addresses look correct in structure. The zip codes match with the city.

Can I just send these out again? I've never ran into this problem before.
