In accordance with the specifications of the Universal Postal Union (UPU) and the International Post Corporation (IPC), electronic data for all international consignments containing goods must in future be sent to the postal organizations abroad in advance. The aim is to simplify customs clearance, reduce transit times and provide transport companies with goods information by disclosing detailed data about the sender, recipient and consignment content. WebStamp offers the convenient option of entering the required data yourself. The necessary fields are displayed automatically once you indicate in WebStamp that you want to send a consignment containing goods abroad.

Stamps created with WebStamp are valid for a period of one year.

The validity period is shown accordingly in our online service when you create the postage paid impressions. No expiry date is printed on the postage paid impression or included in the data matrix code. Once the official period of validity of a stamp created with WebStamp has expired, it can still be used without any surcharge. A problem arises in the event of a price increase. Personalized stamps should always show the correct value of a product/postage. Consignments with multiple WebStamp franking cannot be processed in the letter processing centers as the system reader only records a data matrix code. The expiry date is therefore required to avoid too large a number of personalized stamps being created and stored.

Validity example: as long as an A Mail item costs CHF 1.00, it is still possible to use a personalized stamp with a face value of CHF 1.00 but which is older than one year. Following a price increase, a consignment franked with WebStamp can only be re-franked in a Swiss Post branch or branch with partner using a postage stamp. Postage stamps created using WebStamp cannot be returned or cancelled.


Very occasionally, an error may occur when printing a postage paid impression. If your postage paid impression is not correctly printed on your label sheet, please check the printer settings. Ensure that the “actual size” or “size = 100%” function is selected.

The repeated printing of a PDF document with personalized stamps that have already been created generates no further costs. Every stamp created with WebStamp may however only be affixed to a consignment once.

You will be notified immediately of the use of duplicates so that you can react accordingly. Duplicates are either charged directly to your online account or invoiced to you.


In accordance with the General Terms and Conditions for WebStamp, stamps that have been created with WebStamp may not be copied or printed multiple times. Duplicates refer to consignments handed in for sending that have the same postage paid impression (recognizable by an identical franking ID). Every stamp created with WebStamp may only be affixed to a consignment and sent once. Duplicates will be franked accordingly by Swiss Post. Furthermore, a processing fee of CHF 1.00 per duplicate will apply, with a minimum charge of CHF 10.00. An example: 80 duplicates for a standard A Mail letter cost CHF 160.00, CHF 80.00 postage (80 × CHF 1.00) for the subsequent franking plus CHF 80.00 processing fee (80 × CHF 1.00).

With “WebStamp” you simply pay the face value. Your personal stamps are used just like regular stamps.

The advantage of WebStamp is primarily the fact that you can personalize the postal prepayment impression. Several million personalized stamps sold every year underscore the fact that Swiss Post customers appreciate this personalization. They are happy to accept the slightly higher production costs. The prices of our “WebStamp” labels take account of the fact that you can obtain small quantities (60 items). Smaller volumes are generally a little more expensive – although this is not necessarily a disadvantage to you as you do not need to purchase 300 items from a different provider.

You can avoid paying any label costs if you print the postage paid impressions directly onto the envelopes.

Swiss Post is not entirely free to set its own prices. A postage price adjustment for letters, which are subject to the letter monopoly, can only be decided by the Federal Council. The same applies for the postage paid impressions created using WebStamp.
