How to make a phone call QR code
- Enter the phone numberUse the international format with the country code, for example +91 98765 43210.
- Add a frame with a clear call to action"SCAN TO CALL" or "CALL FOR DELIVERY" tells people what will happen.
- Download PNG, SVG or PDFUse SVG or PDF for signs and vehicle stickers so the code stays sharp at any size.
- Test itScan with a phone: the dialler should open with your number filled in.
How a call QR code works
The code contains a standard phone link such as tel:+919876543210. When it is scanned, the phone opens its dialler with the number filled in. For safety, phones never start the call automatically: the person always taps the call button, so they stay in control.
Always use the country code
Write the number in international format: a plus sign, the country code and the number without the leading zero. For India that is +91 followed by the 10-digit mobile number, for example +91 98765 43210. A number written this way works from any phone in any country, including visitors on foreign SIM cards. Toll-free numbers starting with 1800 usually only work from within India, so add a regular number too if you expect international callers.
Ideas that work
| Placement | Frame text |
|---|---|
| Shop window or shutter, for after-hours orders | "CALL TO ORDER" |
| Vehicle windscreen, so people can reach you if you block a gate | "CALL THE OWNER" |
| Property "for sale" or "to let" boards | "CALL THE AGENT" |
| Service stickers on ACs, water purifiers, lifts | "CALL FOR SERVICE" |
| Pet collar tags | "I'M LOST, CALL MY FAMILY" |
| Delivery menus and pamphlets | "CALL FOR DELIVERY" |
Call, WhatsApp, SMS or contact card?
Pick the code that matches what you want people to do:
| Code type | What happens | Best for |
|---|---|---|
| Phone call | Dialler opens with the number | Urgent calls, service, deliveries |
| Chat opens with an optional message | Orders, bookings, customer support | |
| SMS | Text message app opens | Short replies, keyword campaigns |
| Contact card | Saves your name, number, email and address | Business cards, networking |
The generator above has tabs for call, SMS and WhatsApp, so you can switch without retyping the number.
Privacy on public codes
A number on a sign or vehicle can be scanned by anyone. For vehicles and pet tags, consider a second number or a business line rather than your personal mobile. Since the code is static, you can't switch it off later, only cover or replace it.
Print tips
- Print at least 2.5 cm (1 in) wide on stickers and 10 cm or more on boards read from a few metres away.
- Use dark dots on a light background; weatherproof vinyl stickers last longest outdoors.
- Print the number in digits next to the code too, for people who'd rather type it.
