Are (really) old stamps still valid?

You can continue to use old stamps. All stamps from October 2, 1961, including those in Belgian francs, remain valid for:

  • a non-priority mail within Belgium
  • International mail. In this case you should also stick a blue A Prior label on your mail.

You cannot use old stamps as priority stamps. If you want to send your mail as a priority mail, you will need a priority stamp with a barcode.
