How to use Sagvia
A short visual walkthrough you can send to someone instead of explaining it. Owners register a plate so they can be reached. Anyone can scan a plate and message the owner — without seeing private numbers.
If you own a vehicle
Four steps. Takes a couple of minutes. Your contact details stay hidden unless you choose otherwise.
02
Register your vehicle
Add your number plate and optional model. Privacy stays off by default: your name, phone, and WhatsApp stay hidden unless you turn them on for that car.
03
Put on the small sticker (optional)
Download or print the Sagvia mark — about 4 cm wide — and place it on a lower windscreen corner. It tells others this car is registered: they can scan the plate on sagvia.com and message you.
04
Get the message and reply
When someone writes about your plate, Sagvia emails you (if an email is on your account). Open the link or your Inbox on sagvia.com to reply. Your number stays private unless you chose to show it.
If you need to reach an owner
No account required. Scan the plate, send a message, and continue the chat from the link you get.
01
Scan or type the plate
Open Scan. Photograph the plate or type it. Sagvia looks up whether that vehicle is registered. You do not need an account to do this.
02
Send a short message
If the car is registered, write why you need the owner — blocking, lights on, emergency, or a general note. Leave a way they can reach you back.
03
Keep the chat on Sagvia
You get a conversation link. Replies show in Chats on this device. The owner is notified by email and can answer from their Sagvia inbox.
