What is a phone number QR code?

A phone QR code encodes a tel: URI that, when scanned, opens the phone's dialer with the number pre-filled. The user just taps the call button — no manual number entry needed.

Should I include the country code in the phone number?

Yes, always include the full international format with the + prefix and country code (e.g., +1 for US/Canada, +44 for UK). This ensures the number dials correctly regardless of the user's home country.

What is the difference between a phone QR code and a vCard QR code?

A phone QR code immediately prompts a call. A vCard QR code saves the contact to the phone's address book, which includes the phone number plus other details. Use a phone QR for urgent call-to-action materials and vCard for networking contexts.

Can I use a phone QR code for WhatsApp or other messaging apps?

Not directly with a tel: link. For WhatsApp, use the deep link format: https://wa.me/+15551234567. Encode that URL as a standard URL QR code or use a Social Media QR code type.

Will the phone QR code work on tablets or computers without calling capability?

Tablets and computers may not have cellular capability, but they'll still decode the tel: link. Some devices will try to open a VoIP app or display the number. For most use cases this is fine, as phone QR codes are primarily scanned by smartphones.

What is a Phone QR Code?

A phone QR code encodes a tel: URI containing a phone number. When scanned, the phone displays a "Call" prompt with the number pre-dialed. This removes the friction of typing a phone number and is particularly useful in scenarios where people need to call quickly, such as emergency contacts, customer service lines, or sales inquiries. Phone QR codes are widely used on business signs, vehicle wraps, print advertisements, and business cards.

Always use the international format with country code (e.g., +1 for US) to ensure calls work from anywhere
