Can I pre-fill the text message?

Yes — add a message and it’s encoded so the SMS opens ready to send. The person can edit it before sending.

Does it work on iPhone and Android?

Yes. The number always works on both; the pre-filled message behaves slightly differently between iOS and Android, so scan-test on both before printing.

Why doesn’t my pre-filled message appear on some phones?

iOS and Android use different SMS link syntax for the message body, and some older devices ignore it entirely. The number and recipient always work — treat the pre-filled text as a nice-to-have, not a guarantee.

Does it send the text automatically?

No — it opens the messaging app with the recipient and message filled in. The person taps send themselves.

Do I need an app to make or scan it?

No — you create it here in the browser, and any modern phone camera opens it in the default messaging app.

Will an SMS QR code expire?

No. The SMS link is encoded directly into the code, so it works forever and offline.

Can I change the number later?

No: the number is written into the pattern when you generate the code, so a new number means generating and printing a new one. If it changes often, point a dynamic URL code at a contact page instead.

Free SMS QR Code Generator (Pre-Filled Text Message)

Let people text you with a scan

Enter your number above and an optional pre-filled message, and download a free SMS QR code. Scanning it opens the person’s messaging app with your number, and your message, ready to send. It suits competitions, voting, enquiries and “text to book” campaigns, where a short text beats filling in a form. It’s made in your browser, so nothing is uploaded.

To make one:

1
Enter the phone number
The number that should receive the text. Use the full international format if your audience may be abroad.
2
Add a pre-filled message (optional)
For example “BOOK” or “Send me the menu” — handy for keyword campaigns and voting.
3
Scan-test on iPhone and Android
SMS link handling differs slightly between platforms; check both before a print run.
4
Download free
PNG for screens or vector SVG/PDF for print — no watermark.

Test on iPhone and Android

iOS and Android handle SMS links slightly differently — particularly the pre-filled message. iOS uses sms:&body=… and Android sms:?body=…; this tool encodes a widely compatible form, but the number always works even where the pre-filled body doesn’t. Always scan-test on both before printing a batch.

When to use SMS over a chat app

SMS wins when you can’t assume which messaging app someone has: every phone can text, no app or account needed. That makes it reliable for the general public, older audiences and one-word keyword campaigns. If your audience is on WhatsApp and you want richer replies, a WhatsApp code is the better fit; for a written enquiry with a subject line, use an email code.

Where to use an SMS QR code

Text-to-vote and competition entries with a keyword
Keyword reservations on posters and table tents (“text BOOK to reserve”)
Quick enquiries from packaging, vans and signage
Opt-ins for SMS reminders and alerts
Feedback prompts where a short text is easier than a form
