Swiss (CHE) Tax Registration Number Change Notice

Replacement VAT number six figure identification number of firms (FDI) with the VAT extension

The federal law on business identification number has changed with effect from 1 Jan 2014.  The old registration number format was 8 characters but the new format supports 19-20 characters. 

Old Behavior

The current VAT number validation format is CH + 6 digits (the six
digits after the prefix should be numeric). Example: CH123456. Swiss companies
can continue to use the current VAT number format until the end of 2013.

New Behavior

Effective from January 2014, there are changes in the validation of Tax
Registration Number. The new VAT number validation is formatted as CHE + nine
numeric positions + extension. Example: CHE-123.456.789 MWST.

The following validation is implemented.

  • CHE - is a fixed value. It represents the country code.
  • to separate the country code
    and the tax number portion.
  • 123.456.789 - nine numeric positions, separated by periods.
  • (Blank) - blank position that separates the numeric portion and the
    extension portion.
  • XXXX  : Depending on the
    specific part of Switzerland the company address belongs to. The three possible
    extensions are: MWST, TVA or IVA.

The total length of the new VAT number, therefore, can be 19 or 20


a) Apply Patch 15964400 as detailed in Doc ID 1521534.1 - New Swiss (CHE) Tax Registration Number


b) Enter/update existing tax registration number as
per new format before January 2014 to avoid any user interface, reporting or
data issue. The tax registration number as per old format will not be valid
effective from January 2014.

You can enter the registration number using multiple
navigations but the most common interface is: Tax Manager > Parties: Party Tax Profiles > Tax Registrations



For full details on this change in legislation, please review the Federal Administration website.

    The example provided is an invalid one.

    When providing as an example, you can provide a valid one.

    Not sure if you can use other company's registration numbers, but

    CHE-318.065.437 MWST is a valid one.

    Thanks for your comment but we only validate the format and not the number. The number is the prerogative of the tax authority and we do not do online validation.

    Hope this clarifies the issue.
