Address Requirements Swiss Post

Letters sent to Switzerland, once printed, are forwarded to Swiss Post for delivery. From this point onwards, further responsibility lies with Swiss Post. To ensure that your letters can be processed smoothly and for the agreed prices by Swiss Post, it is important that the recipient addresses comply with specific requirements.

In this article, we have summarised the most important address requirements of Swiss Post for you.

To provide our customers with the best possible support in complying with these requirements, Pingen checks the recipient address for additional requirementsfor letters to Switzerland since July 1st 2024. Learn more about the address checks of Pingen

If there are problems processing the recipient's address, Swiss Post may reject the letter or only deliver it for a surcharge. In such cases, no reimbursement will be made as the correct addressing is the sender’s responsibility and the costs cover the additional processing effort. To ensure that the address meets the postal address requirements, we recommend sending a test letter via Pingen and verifying successful delivery. In this way, potential problems can be recognised and rectified at an early stage to ensure smooth delivery.

Address verification by Pingen (since July 1st 2024)

To help you meet the requirements of Swiss Post, Pingen checks the recipient address for compliance with additional requirements since July 1st 2024 for letters to Switzerland.

If Pingen detects that a document does not comply with the address requirements, it will receive the status "Action required" after upload. The "cover page feature" enables you to correct the recipient's address directly via Pingen. This feature automatically adds a new page in front of the document. This allows the address to be re-entered in compliance with the address requirements and placed on the cover page accordingly.

The following requirements are checked by Pingen since July 1st 2024:

Prohibited content in the postcode line

In the address line with the postcode and the city, the postcode must appear before the city. In addition, there must be no characters (such as a comma or hyphen) between the postcode and the city. Both pieces of information must be separated by a space. Pingen checks whether the order is correct and whether there is a space after the postcode.

In addition, country designations before the postcode such as CH- or CH should be avoided, as these are no longer accepted by the Post.

Please make sure that the line with the postcode only contains the postcode and the city and that they are separated by a space. For example, 3000 Bern (and not “3000, Bern” or “CH-3000 Bern” or “CH3000 Bern” or “Bern 3000”).

Postcode does not have 4 digits

In Switzerland, postcodes that are not 4-digit are considered invalid. If a recipient address has a postcode with fewer or more than 4 digits, it will be rejected by Pingen. Pingen checks whether the last or second-last address line contains a 4-digit postcode.

Please ensure that the zip code is a continuous 4-digit number. For example, 3000 Bern (and not "300 Bern" or "3 000 Bern").

In case the letter shall not be sent to Switzerland, please ensure that only the recipient country is indicated on the last address line in one of the supported spellings.

Country designation on the last address line

The Swiss Post specifies that the country should be the sole content of the last address line. For this reason, Pingen checks whether there is a country designation (such as “Switzerland” or “Schweiz” or Suisse” or “Austria”)

Please make sure that the country name is on the last address line and that the address line with the postcode does not have a country name. For example, 3000 Bern (and not “3000 Bern Switzerland“ or “3000 Bern, Schweiz” or “1000 Wien, Austria”).

Invalid Address Structure (Soon)

When sending letters to Switzerland, it is mandatory to include a recipient name in the address. Furthermore, no empty lines (or lines without content) are allowed between the different address lines. In addition, the address line with the street name/house number or P.O. Box must be followed by the address line with the postcode/city. In addition, neither the address line with the street name/house number nor the address line with the postcode/city may be split over multiple address lines.

Please ensure that the address contains a recipient and no blank lines between the address lines, that the address line with the street name or P.O. box is followed by the address line with the postcode/city and that both the address line with the street name and the address line with the postcode/city are shortened so that they each fit on one address line.

Important:

For technical reasons, Pingen cannot carry out a complete verification of the requirements by Swiss Post. The address check by Pingen serves solely to help identify various problems before sending the letter. However, it is the sender's responsibility to ensure that letters sent to Switzerland via Pingen comply with Swiss Post regulations. Any additional expenses due to incorrect addressing will be charged by Pingen.
