What can and can’t I send abroad?

For legal, health or security reasons, Post CH Ltd is not authorized to transport certain goods abroad. You can find more information in our brochure   "Dangerous goods in international mail" (PDF, 618 KB) or by calling the international customer service on 800 888 100.

You weren’t at home when the postman came by? Is it not possible for you to collect a missed consignment from the post office?

No problem! Swiss Post has a range of alternatives to ensure you can receive your parcel or registered letter quickly and easily.

For example, order a second attempted delivery on a day that suits you. Or simply forward your consignment to another post office, a PickPost point or any other address anywhere in Switzerland or the Principality of Liechtenstein. Of course, you can also extend the collection period or issue someone with a single authorization to collect your postal item.

Here’s how easy it is: Enter the number of your collection note at Then select the desired service.


How can I check the delivery status of a consignment?

Have you posted a consignment or are you expecting mail and you would like to know where the item is currently located? To find out, you must be in possession of the barcode number (consignment number on the postal receipt). At, you will find the "Track & Trace" box on the right-hand side. Please enter the 18-digit barcode number in the relevant field and click on "start". The "Track & Trace" window opens and the consignment data are displayed together with the events.

Why can I not find the direct telephone number of my post office?

The direct telephone numbers of post offices have not been published for a number of years. The central customer service offers an easy-to-reach and professional contact point which you can call on 0848 888 888. Wherever possible, the customer service endeavours to provide a direct answer to all enquiries concerning postal matters. This helps to take the burden off the post offices and to avoid situations whereby calls taken by counter staff lead to longer queuing times for customers at the post-office counter.

Can an enquiry be requested for every logistics product?

If mail goes missing, Swiss Post will, on request, be happy to launch an enquiry and clarify the situation. However, please note that enquiries can only be launched for letters or parcels with barcode numbers (ID number on the post office receipt) and you must have the barcode number in order to launch the enquiry. Enquiries cannot be launched for unregistered mail such as A Mail letters and B Mail letters.

What happens to mail once the deadline for collection has expired?

If a letter or a parcel is not collected by the recipient before the deadline for collection expires, that letter or parcel is returned directly to its sender. Swiss Post cannot disclose any information about the sender, etc. to you. However, most senders contact the recipient directly when mail is returned to them undelivered.
