QR Code Generator for Phone Numbers: Click-to-Call QR

Create Click-to-Call QR Codes for Phone Numbers

A phone number QR code encodes a tel: URI that, when scanned, prompts the user to call the number directly from their phone. No dialing, no memorizing digits, no typos. It is the fastest way to bridge print media and a phone call — perfect for business cards, restaurant menus, service stickers, and emergency contact signage.

Phone QR Code Format

# International format (recommended)
tel:+14155551234

# With country code for different regions
tel:+442071234567   (UK)
tel:+81312345678    (Japan)
tel:+923001234567   (Pakistan)

# SMS instead of call
sms:+14155551234
sms:+14155551234?body=Hi%20I%20saw%20your%20ad

International Formatting Best Practices

1. Always use E.164 format — start with + followed by the country code, then the full number with no spaces, dashes, or parentheses. Example: +14155551234 not (415) 555-1234
2. Include the country code — QR codes on business cards may be scanned anywhere in the world. Without a country code, the call will fail outside your country.
3. No trunk prefix — omit the leading 0 used in domestic dialing. UK: +442071234567 not +4402071234567

Use Cases

• Business cards — scan to call without manually entering the number into contacts
• Restaurant menus — "Scan to order by phone" or "Scan for reservations"
• Service stickers — appliance repair, plumbing, HVAC companies place QR codes on the equipment they service
• Emergency contacts — medical alert bracelets, building safety signage, vehicle emergency cards
• Real estate signs — "Scan to call the listing agent" on for-sale signs
• Product support — printed on packaging or manuals for quick access to customer service

Call vs SMS

Use tel: for voice calls and sms: for text messages. You can even pre-fill the SMS body:

# Pre-filled SMS for appointment booking
sms:+14155551234?body=I%20would%20like%20to%20book%20an%20appointment

# Pre-filled SMS for order inquiries
sms:+14155551234?body=Order%20inquiry%20%23
