Online registered letters are valid
Yes, you can send a registered letter online via bpost.be. The online registered letter has the same legal value as one submitted at a post office: tracking number, proof of sending, and presumption of receipt on the 3rd business day. Bpost prints, envelopes, and delivers the letter physically.
The process is simple:
- You upload your document as a PDF
- Bpost prints and envelopes it
- Bpost sends it as a physical registered letter
- The recipient receives a standard registered letter in their mailbox
- You receive digital proof of sending and a tracking number
This is not an email or electronic document — it is a physical letter that bpost prints and delivers on your behalf.

Legal value and proof
The online registered letter provides the same legal guarantees:
- Proof of sending: digital receipt with date and tracking number
- Tracking: real-time tracking of delivery status
- Presumption of receipt: on the 3rd business day after physical dispatch (not upload)
- Acknowledgment of receipt (optional): signed confirmation from the recipient
- Proof of content: you retain a copy of the exact document sent
Important: the presumption of receipt date is calculated from the date bpost physically dispatches the letter, not the date you upload it online. Allow 1-2 business days for processing.
