Parked somewhere? Your car can still reach you.
A ShieldTag on the windshield or dash lets anyone flag you down about your car — a blocked driveway, headlights left on, an alarm going off, even an emergency — without your phone number ever being on display.

Best on the windshield, dash, or rear glass of any car, truck, or van you park in public.
How it works
- 1
Stick the tag
Peel and stick it on the windshield, dash, or rear glass. Takes under a minute.
- 2
Someone scans it
A blocked driveway, lights left on, an alarm going off, a minor bump — anyone with a phone camera can scan the tag and reach you.

You get the message
It lands as a text. Reply if you want — your number stays hidden on both ends.
What's live today

Questions
Is my phone number ever visible?
No. Messages relay through ShieldTag in both directions — the person at your car never sees your number, and you never see theirs unless you reply.
Does it work for trucks, vans, or motorcycles?
Yes — any vehicle with a surface to stick it on. Bikes, e-bikes, and scooters have their own tag placement guide on the bikes & scooters page.
What does it cost?
Anonymous messaging is free, forever. A physical tag is a one-time purchase from $6.99; paid plans add photos and more starting at $1.99/mo.
- ShieldTag is not an anti-theft or GPS tracking device — it relays a message only when someone scans the visible tag.
