SMS QR Code

SMS QR Code creates sms:recipient and optionally appends ?body= with component-encoded message text. It does not validate the recipient, send a message, calculate carrier charges, select SIM, guarantee body compatibility, or protect the content from anyone who scans the PNG.

Quick answer

Does scanning an SMS QR send the message?

No. A compatible messaging app may open a draft for user review.

SMS URI handling is device and application dependent

The URI proposes a destination and optional body, but mobile platforms differ in query syntax support and confirmation flow.

How it works

Enter the phone destination and optional message. The body is percent-encoded and appended to an sms: URI before QR generation.

Key concepts

The user must control sending

Prefilled communication should be visible and editable.

Platform compatibility varies

Some clients treat SMS URI query fields differently.

When to use it

Open a prefilled opt-in keyword draft.
Create a support-text shortcut.
Reduce typing of a short standard message.

When not to use it

Do not encode sensitive text.
Do not assume sending is free or automatic.
Do not expect recipient or carrier validation.

Worked examples

Recipient only

Input: +4512345678
Expected output: sms:+4512345678

No body query appears.

Keyword draft

Input: 12345; message JOIN
Expected output: sms URI with body=JOIN

A compatible app may prefill it.

Invalid recipient

Input: service
Expected output: QR generated

No address check is performed.

Common mistakes

Expecting automatic sending

The QR only contains a URI. Correction: Require user review and action.

Ignoring rates

Carrier fees and short-code charges may apply. Correction: Disclose costs separately.

Encoding private text

The payload is plainly decodable. Correction: Keep sensitive content out.

Best practices

Display recipient, action, and cost context.
Keep the body short.
Test on target mobile platforms.

Limitations and privacy

No sending, validation, pricing, delivery, SIM, or compatibility checks.
One recipient and optional body only.
Encoded text is not confidential.

Generation happens locally in this browser. The PNG contains the entered payload, so share it with the same care as the underlying data.
