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 a WhatsApp QR Code Works

      The code holds WhatsApp's click to chat link, https://wa.me/ followed by the number and an optional text parameter.

      The Number Format

      WhatsApp asks for the full international number without zeros, brackets or dashes. The generator removes spaces and the +, and refuses numbers that start with 00.

      WhatsApp QR code with the wa.me link for the example number +1 212 555 0100 and the message Hi, I saw your sign.
      The wa.me link: the number without + or spaces, then the message.

      This Is Not the WhatsApp App's Own Code

      Many searches for WhatsApp QR codes are about the codes inside the WhatsApp app itself, such as the one for WhatsApp Web. The code made here is different: a web link anyone can open to start a chat with you.

      Where WhatsApp QR Codes Help

      A chat code lets customers reach you on WhatsApp without saving your number first.

      Examples

      • Shops: a code at the counter for orders and questions.

        WhatsApp QR code that opens a chat with the example number and the message I have a question about my order.

      • Listings: a code on a sign with a message naming the item.

        WhatsApp QR code that opens a chat with the message Is the blue bike still available?

      • Events: a code that starts a chat for bookings.

        WhatsApp QR code that opens a chat with the message I would like to book two places for Friday.

      Common WhatsApp QR Code Problems

      Most failures come from the number format.

      What to Check

      • Country code: the number must start with the country code, without 00.
      • Account: the number must have a WhatsApp account.
      • Message: keep the message short; it is part of the code.

      Frequently Asked Questions

      Does the Person Need to Save My Number?

      No. The click to chat link opens a chat with your number directly.

      Does the Message Send Automatically?

      No. It appears in the chat's text field, and the person sends it.

      Why Does the Generator Remove the +?

      WhatsApp's click to chat format writes the number without + or other symbols, starting with the country code.

      Can I Use a WhatsApp Business Number?

      Yes, any number with a WhatsApp account works in the link.

      Is the WhatsApp QR Code Generator Free?

      Yes, with no account, watermark or download limit.

      Is My Number Sent to Barcode.codes?
