Field 24 formats

The content of field 24 can vary depending on the vehicle's type of approval:

Standard Swiss approval

Examples:

  • 1TD812
  • 1FA502
  • AXA158

Combination of letters and numbers (e.g.: 1XX000 or XXX000). This is the most common format for vehicles directly approved in Switzerland.

Special mentions

  • IVI / IVIX
    Search by registration number (field 18)
  • X
    Search by VIN (field 23)

Special cases (IVI, IVIX, X)

Some vehicles do not have a standard type approval in field 24. Here is how to handle them:

The mention IVI in field 24 indicates that the vehicle was individually imported and registered based on a European certificate of conformity (CoC) or an electronic data sheet, without a traditional Swiss type approval.

IVIX has the same meaning, but the "X" indicates that the importer has refused publication of certain data for data protection reasons.

How to search: Use the registration number from field 18 of the vehicle registration document. This number is in the format XXX.XXX.XXX (9 digits, soon 12 with an additional .XXX).

Note: These vehicles are direct imports (new or used), registered via the eCOC system rather than through a traditional Swiss type approval.

An "X" in field 24 means the vehicle was individually imported without a recognised Swiss or European type approval. These vehicles were individually approved by a cantonal road traffic authority.

How to search: Use the VIN (chassis number) from field 23, or search by brand and model.

Note: These vehicles are often parallel imports, vintage vehicles or rare models not officially approved in Switzerland.

How to search for these vehicles?

  • IVI / IVIX -- Search by registration number (field 18), format XXX.XXX.XXX
  • X -- Search by VIN (field 23) or by brand and model
