I got my letter back because the address was incorrect. How do I know if I am using the correct address?

To be sure of the correct address, you can validate it online on the bpost website. You check if the address is known at bpost and if the person still lives there. If your addressee has moved, you will have to ask him/her for the new address. Note: if you got your letter back because the address was incorrect, use a new envelope and new stamps.

If you didn't find an answer to your question?
