Debt collection documents
Delivery of orders to pay and bankruptcy notices

Consignments are identified using the barcode for debt collection documents. A barcode must be placed on the debtor duplicate above the delivery address (= address of the debtor, their legal representative or deputyship) and on the creditor duplicate above the return address (= address of the debt collection office). The debtor duplicate with the delivery address must be on top in each case.

For your consignments to be processed properly, we recommend having Swiss Post check the addressing, the paper quality and the correct preparation and placement of barcodes in advance.

For verification and approval, please send five samples of your orders to pay and/or bankruptcy notices to the following address:

Post CH Ltd

Logistics Services

Operations

Härkingen letter/parcel center

Final proof

Lischmatt 40

4621 Härkingen

DataTransfer is the electronic interface facilitating the direct exchange of consignment/billing data and status reports between you and Swiss Post. DataTransfer simplifies consignment posting and creates transparency in the entire shipping process. Data exchange with Swiss Post via DataTransfer works for all consignments with a barcode, which means debt collection documents too. Data is transmitted via Secure File Transfer Protocol (SFTP) connections or sedex (for a fee).

More information on DataTransfer can be found at www.swisspost.ch/datatransfer-letters or in the guide “Debt collection documents with DataTransfer” (PDF, 932.3 KB). To implement DataTransfer, please get in touch with your software provider and your contact at Swiss Post directly. If you use DataTransfer, once you send the consignment data, you will receive the DataTransfer delivery note automatically for posting as a PDF.

Letter mail easy is available for franking debt collection documents. Letter mail easy enables you to carry out the franking and declaration process electronically, and you receive a monthly invoice for postage costs.

Detailed information can be found at www.swisspost.ch/letter-mail-easy.

Orders to pay folded (debtor and creditor duplicate folded together with debtor duplicate on the outside) to A5 format (148 × 210 mm) and posted in collective envelopes/folders.

As of 1.1.2026, you will only be able to submit your debt collection documents with Letter mail easy. Letter mail easy enables you to carry out the franking and declaration process electronically, and you receive a monthly invoice for postage costs.

Prepare the envelopes by postcode and address them as in the following example:

Post CH Ltd
Delivery office
Debt collection documents
Street
Postcode Location

If you do not use DataTransfer, attach completed barcode list 21 or 23 to your consignments for mailing (outside the envelope). The relevant forms can be found at www.swisspost.ch/docucenter.

With the “Track consignments” online service, you can track the progress of your registered letters along the entire route.

Delivery

Debt collection documents are delivered on the next working day (Monday to Friday). The creditor duplicate containing the delivery notification and any legal objection is returned to the debt collection offices.

Debt collection documents can also be dispatched by debt collection offices outside the debt collection district. Please note that such debt collection documents must be produced in the relevant language of the destination or be provided in two languages.

If you have agreed a special delivery with us, please bear in mind the relevant restrictions.

Special delivery

If the first delivery attempt by Swiss Post is unsuccessful and the debt collection document is not collected at the counter within the seven-day deadline, we recommend using special delivery. Details can be found under Special delivery. Important: special delivery is only possible within the relevant debt collection district.

The withdrawal order enables you to withdraw debt collection documents that have been posted and are already being processed by Swiss Post. You can find more information in the “Withdrawal of legal documents” factsheet (PDF, 60.2 KB).

If debt collection documents cannot be delivered to the domicile address or P.O. Box, Swiss Post notifies the recipient that they may be collected within the next seven days from the nearest self-operated branch (not from branches with partners). Once this deadline has passed, Swiss Post sends the consignment to the debt collection office.

If you would like Swiss Post to carry out further delivery attempts after the deadline has expired, the Legal documents with special delivery service is the ideal solution.

Debt collection and bankruptcy offices may order postal interceptions of mail deliveries during bankruptcy proceedings. To do so, send the individually prepared temporary forwarding order in written form directly to the delivery point. An extension beyond a period of twelve months is possible with a fee-based order.
