Just like with electronic addresses, one letter can affect the proper delivery. Validate your address to be sure that it is known at bpost. The photo below shows how to write the address of the addressee correctly. Don't forget to mention the name of the addressee (required) and to put your own address on the back of your letter (recommended but not required).

The maximum dimensions your letter can be are:

• length: 350 mm
• width: 230 mm
• thickness: 30 mm

If your letter weighs more or is longer, wider or thicker, you will need to send it as a parcel. In that case, you need a shipping label.
