Product information


An Urgent Certified Letter is the fastest and most secure option to send important documents that contain personal data such as signed contracts or estimates.

  • Maximum speed: deliveries in 24 hours, with the origin and destination in large towns or cities.
  • Greater security: each shipment is individually identified and registered with a barcode printed on one of our labels. When the shipment reaches its destination, the person who receives it must sign for it. If delivery cannot be made, we will leave a notification in the postbox stating the Post Office where it can be collected within 15 days. 
  • For your peace of mind: check the progress and control of your letter free with our Shipment Tracker.
  • Nearby: this option is only available for shipments within Spain. 

Shipment details

You choose your perfect packaging. Of course, the size must fit these measurements:


  • Envelope or box: Length + Height + Width = 90 cm, with no measurement being more than 60 cm.
  • Roll or tube: Length + twice the diameter = 104 cm, with no measurement exceeding 90 cm.


  • Envelope or box: 14 x 9 cm.
  • Roll or tube: Length + twice the diameter = 17 cm, with no measurement being less than 10 cm.

If you want to send something smaller, don't worry, you just have to add a 10 x 7 cm label with the address and postage.

And it should weigh no more than 2 kg 

Now you just have to tell us where you would like us to send it:

  • It is important that your details and those of the recipient are clearly visible on the packaging.

  • Remember that you can generate the label and pay for the shipment here.
