Frequently Asked Questions
Everything you need to know about Karo Alert vehicle tags, privacy, and calling security.
Will the person scanning see my phone number?
No, never. Karo Alert uses a secure server-side virtual call bridge. When a person scans your tag and initiates a call, both parties' phone numbers remain 100% masked and confidential.
Does the scanner need to install any app?
Not at all! Anyone can scan your Karo Alert QR tag directly using their standard phone camera, Google Lens, or Paytm/WhatsApp scanner. It opens directly in their browser.
Is the tag waterproof and weather resistant?
Yes. Every Karo Alert tag is constructed from industrial-grade polycarbonate film with UV protection and 3M adhesive. It easily withstands heavy rain, high heat, car washes, and dust.
Are there any monthly or annual subscription fees?
No monthly charges. When you buy a Karo Alert tag, you get lifetime free service and call routing on that vehicle with zero recurring subscription.
