SMS QR Code Generator
Opens the messaging app with a phone number and, on many devices, a pre-filled message.
Generate a scannable sms: QR code from phone number and optional message. When someone scans it, their messaging app opens with the number filled in, and many devices also honor the pre-filled message body.
Include country code for international numbers.

Enter text to generate a QR code
It's recommended to include the country code in international format (e.g., +14155551234, not 415-555-1234). Without a country code, the receiving phone may not parse the number consistently across regions, resulting in scans that open with incorrect digits or fail entirely.
The body is URL-encoded, but support for pre-filled SMS text still varies by platform. Apple's SMS URL documentation only guarantees the sms:<number> form without message text, so leave the body blank if maximum iPhone compatibility matters more than prefilling.
Frequently asked
- Does this work on iPhone and Android?
- The phone number part does. Open QR Maker emits a standard
sms:link, but message-body prefilling is less consistent: many Android flows support it, while Apple only documents the number-only form. - How long can the prefilled message be?
- There is no hard QR-side limit, but keep it short. Long bodies make the QR code denser, and many phones split long texts into multiple SMS segments anyway.
- Why include the country code?
- A number without a country code is interpreted relative to the device's home region, which is unpredictable for posters or packaging seen in multiple countries. International format (
+...) is the only safe choice. - When should I use this instead of the phone mode?
- Use SMS for "tap to message" use cases (opt-in keywords, support text lines, anything where the user types). Use phone for "tap to call" use cases (helplines, restaurant reservations, emergency contacts).
- What's the difference from the URL mode?
- You can put a
sms:URI into the URL mode, and it will work, but the SMS just saves you remembering the URI scheme. Same output otherwise.
