Although opening an account in Switzerland is more seamless in person, there are still many other ways that Swiss banks allow you to open an account. The most common ways are typically by mail or fax, given you provide a few details and some essential documentation.
Due to Switzerland's strong anti-money-laundering regulations, there are laws
that require you to show a few pieces of information prior to your investment account in Switzerland to be opened. These documents can include passport copies, documents which outline your occupation as well as your tax returns, business and corporate documents and licenses among other things. You must also prove that the source of your deposit is legal.
On top of that, you also have to provide some personal information like your date of birth, name, and address as well as a utility bill for confirmation. After the launch of your Swiss investment account, banks will want to know what you are going to use the account and its funds for.
