How to Create an SMS QR Code
An SMS QR code uses the SMSTO: format to encode a destination number and an optional
message. When scanned, the phone's messaging app opens with the recipient and text already in place -
the perfect frictionless path for keyword campaigns, opt-ins and "text us" prompts.
Step by step
- Enter the phone number with country code (e.g.
+1 234 567 8900). - Optionally write the message you want pre-filled, such as a keyword like
JOIN. - Customise and download the code for your signage or print material.
Great for
Keyword Opt-ins
"Text JOIN to subscribe" - pre-fill the keyword so sign-up is one tap.
Voting & Polls
Each option gets its own code with the vote text ready to send.
Quick Contact
Let people text a shop, agent or support line without saving the number first.
Tips
- Always include the country code so the message routes correctly from any region.
- Keep the pre-filled message short - long text lowers scan reliability.
- The code opens a draft; it never sends on its own.
