SMS QR Code Generator

Make a free SMS QR code: scanning it opens a new text message to your number, with a message already written if you add one. The person still presses Send. The generator writes the standard sms link with the country code and shows it in full. Download SVG, PNG, PDF or EPS.

Error correction

The share of the code that can be damaged and still be read (DENSO WAVE). Higher levels make a larger code.

Printed in the file with the barcode, outside the quiet zone, in Helvetica or Courier so it looks the same in every format.

Bar width reduction0 mil

Makes each bar thinner by this amount, to make up for ink that spreads on paper. Ask your printer for the value, or leave 0 for laser and thermal printing.

Rotation and backgroundNew0° · Filled

Rotation

In the preview, a checkered pattern shows the transparent areas. Print a transparent barcode only on a white or very light surface: scanners need the light quiet zone around it.

Margin and borderNew0 mm · no border

The margin is blank space outside the quiet zone, for cutting; the border is drawn at the outer edge. Both count in the print size.

Link tracking (UTM)NewOff

Adds utm_ parameters to the link so analytics can tell where a scan came from. A longer link makes a denser code.

      How to Create an SMS QR Code

      Enter the number and an optional message, check the encoded link, and download the code.

      1. Type the number with + and the country code.
      2. Add the message the text should start with, such as a keyword.
      3. Check the encoded sms link, then download the code.
      4. Scan a test print and check the message opens correctly.

      SMS QR Code Fields

      An SMS QR code holds the phone number and, if you add one, the start of the message.

      How an SMS QR Code Works

      The code holds an sms link, defined in RFC 5724, with the message in its body parameter.

      Other SMS Formats

      Some codes use SMSTO:number:message, which ZXing has seen in use without an official specification. The generator writes the RFC 5724 form, and the Barcode.codes scanner reads both.

      SMS QR code in the RFC 5724 sms: form, for the example number +1 212 555 0100 and the message Please call me back.
      The RFC 5724 form: an sms link with the number and the message.

      Where SMS QR Codes Help

      A text message code works well for sign-ups, keywords and replies that should arrive by text.

      Examples

      • Keywords: a code that starts a message with a campaign keyword.

        SMS QR code that starts a text to +1 212 555 0100 with the keyword JOIN.

      • Appointments: a code that starts a booking request.

        SMS QR code that starts a text to +1 212 555 0100 asking to book an appointment.

      • Feedback: a code at a counter for a quick text reply.

        SMS QR code that starts a feedback text to +1 212 555 0100.

      Common SMS QR Code Problems

      Problems come from the number or from phones that cannot send texts.

      What to Check

      • Country code: include + and the country code so the message reaches you from abroad.
      • Message length: keep the message short; long text makes a dense code.
      • Devices: tablets without a phone plan may not be able to send texts.

      Frequently Asked Questions

      Does Scanning the Code Send a Text?

      No. It opens a new message with the details filled in; the person presses Send.

      Can the Message Be Changed Before Sending?

      Yes. The message only fills in the text field; the person can edit it.

      Which SMS Format Does the Generator Use?

      The sms link of RFC 5724, such as sms:+12125550100?body=Hello.

      Does It Work With Short Codes?

      The generator asks for a full international number. Short codes are not covered.

      Is the SMS QR Code Generator Free?

      Yes, with no account, watermark or download limit.

      Is My Number Sent Anywhere?

      No. The code is built and drawn in your browser.
