Is registered mail automatically priority mail?

The difference between priority and non-priority is in the delivery period.

• Letters with a non-priority stamp are delivered within maximum 3 workdays.
• Letters with a priority stamp are delivered the next workday.

The number of stamps you attach to your letter depends on:

• the destination
• the size and weight of your letter

Quickly find how many stamps your letter requires via our overview page. You can calculate the price of your letter at the same time.

To have your letter delivered tomorrow within Belgium, use a prior seal and deliver your prior letter before the last collection in:

• A Red Letter Box. You will find the time of the last collection on the letterbox.
• A Post Office or Post Point. You'll find the time of the last collection in each office.
