When do I receive the proof of deposit when dropping off my registered mail in a Red Letterbox?

You receive the proof of posting when your mail item enters our network. It is advisable to check the collection times for the Red Letterbox in question. If you drop off your mail item after the last collection of the day it will only enter our network next working day.

The proof of deposit will appear in the My bpost app and is a legally valid document proving that your mail item has been posted.
