SMS QR Code Best Practices
Follow these tips to maximize the performance of your sms QR codes.
Keep Messages Short
Pre-filled SMS should be brief — a keyword like 'JOIN' or 'HELP' works better than a full sentence.
Comply with TCPA/GDPR
Ensure your SMS opt-in flow complies with local telecommunications regulations (TCPA in US, GDPR in EU).
Use Short Codes for Marketing
For mass SMS campaigns, use a registered short code (5-6 digits) instead of a standard phone number.
Pair with Auto-Reply
Set up an automated SMS response to confirm opt-in and provide immediate value (e.g., a coupon code).
Frequently Asked Questions
Common questions about sms QR codes answered.
How does an SMS QR code work?
It encodes an sms: URI with a phone number and optional body text. When scanned, the phone opens the SMS app with the fields pre-populated.
Will the message send automatically?
No. The SMS app opens with the message pre-filled, but the user must manually tap 'Send'. This prevents unwanted charges.
Can I use a shortcode number?
Yes. Any valid phone number or registered shortcode can be encoded. Shortcodes are recommended for marketing campaigns.
Does this work internationally?
Yes, as long as the recipient's phone supports SMS and the destination number is valid. Include the country code for international numbers.
