How do I receive proof of payment for registered mail?

Registered Mail offers you extra certainty. The following table shows you the difference between both types of mail. 

Only the addressee(s) or those with a postal mandate from the addressee(s) can accept registered mail. The item is only delivered after signing for receipt and checking the ID card of the addressee(s) or postal proxy. The sender determines who the item must be handed over to.  

Yes, you also receive proof of deposit when sending registered mail. If you have the person at the counter create your registered mail item, you will be given a paper proof of deposit. If you create your registered mail item in the My bpost app, you will see a digital proof of deposit when the registered item enters our network. In both cases, proof of deposit is a legally valid document proving that your mail item has been posted.
