I'm not able to input my VAT number in Switzerland

What is the VAT format in Switzerland? Should it not be 0?

If your shop is located in Switzerland, the VAT format must be entered strictly as per the below example, depending on the language of your shop :

In FR : CHE-111.111.111 TVA
In DE : CHE-111.111.111 MWST
In IT : CHE-111.111.111 IVA

Careful : Don't forget the "TVA", "MWST" or "IVA" at the end.

Moreover, the VAT in Switzerland is not applied to orders as long as you give us a valid VAT number. Without a VAT number, we can't verify this and must apply VAT to your order.
