Made a mistake

We recently sent out our save the dates a few weeks ago and we unfortunately got one returned due to person moved (not a big deal) but upon reviewing the envelope I have noticed a huge mistake. When making my stamp for our return address I jut noticed I transposed our address. The numbers were suppose to be 7101 but I put 1701. Now I’m scared if someone tries to send a gift or something then we won’t receive it. I will definitely be getting a new stamp before invites go out but I’m not sure if I should post something on my fb to inform of the mistake or just let it go and make sure when invites go out that the return address is correct. What would you do in this situation?
