FAQ

Is the prefilled message editable?

Yes. Scanning opens the messaging app with your number and text ready, and the person can edit everything before sending.

Does the SMS send automatically?

No. The code only prepares the message; sending always stays a manual tap, so nobody can be charged without noticing.

Can I use a short code instead of a full number?

Carrier short codes often work only inside one country and one network. A full international number with the country code is the reliable choice.

SMS QR code sending rules, prefilled text and limits

Capacity and limits

The code carries the number and the message body, and the body is what grows the pattern. Keep it to a short line: long prefilled texts cost density on every print, and recipients edit them anyway before sending.

Device compatibility

Android fills both the recipient and the message reliably. iOS opens the Messages app with the number and, depending on the version, may leave the body out — treat the prefilled text as a convenience rather than something you depend on. Sending is always a manual tap on both platforms.

Common mistakes

  • Relying on the prefilled body for something essential, such as a code word a promotion depends on, without printing it as text too.
  • Encoding a carrier short code, which usually works only inside one country and one network.
  • Forgetting that the recipient pays for the message in some plans, which lowers response on cost-sensitive audiences.

Printing and placement

SMS codes are typically scanned from a poster or a counter card at half a metre or less, so 25 to 50 mm covers most placements. Print the number as text next to the code so people can act without scanning.
