What formats are allowed for a registered letter?

The maximum dimensions of your letter are:

  • Length: 350 mm
  • Width: 230 mm
  • Thickness: 30 mm
  • Weight: 2 kg

If the above dimensions are exceeded, the mail item is a parcel and then the following rules apply:

  • The longest side may not exceed 1.5 metres
  • The size may not exceed 3 metres (1 x length + 2 x width + 2 x height = max. 3 m)
  • The maximum weight limit for an inland registered mail item is 10 kg and 2 kg for international mail.

If you want to send a parcel by registered mail, just stick the bar code of the registered mail on the parcel. You do not create a parcel label for this.
