Do I need a stamp to mail a letter?

Post offices require postage stamps on letters to confirm payment for their services, so you do need stamps to send a letter. But what will happen if you send the letter without a postage stamp?

Yes, you do need stamps to mail a letter both for domestic and international routes. The number of letter stamps will depend on the weight, size and destination (domestic or international). Post offices require this proof that postage was paid to help them scan and orient the letter further.

In case you forgot to put a postage stamp on the letter you already sent somewhere, it will be:

  • returned to you (the sender), or;
  • the receiver will have to pay for the missing stamp.

The price the receiver will have to pay depends on the post office. In most cases, the receiver will pay a fee that equals the price of the stamp for the letter, but it can also happen that they need to pay a surcharge for insufficient postage for the unstamped letter.

If the receiver refuses to pay, the letter will be returned to you as the sender. You, as the initial sender, will then have to cover the required fees.
