Yes, you can buy multiple Swiss motorway vignettes at once for a fleet, but how you do it depends on whether you choose stickers or e-vignettes.
- Physical vignette (Sticker): You can buy multiple Stickers at once for all vehicles of a fleet in places such as post offices, border posts, authorized resellers, etc..
- Digital vignette (e-vignette): The official VIA portal allows purchasing multiple e-vignettes, each linked to a different licence plate.
Important: There aren't any discounts for fleets available, the price is always CHF 40 per vehicle. Each vehicle needs its own vignette and can't be transferred. A e-vignette will always be linked to one certain license plate.
