Create a QR code for a pet's contact information

If your pet slips out or gets separated from you, a QR code on a collar or carrier can help someone reach you. The code can open a contact card with your phone number and email, so a finder does not have to type your details.

Use the QR Code Generator to make one, then test the code with a phone before printing or attaching it. A QR code is only useful if it scans easily and the contact details are current.

Make a QR code for your pet

1. Open the QR Code Generator and choose the option for contact information.
2. Enter a contact card that will help a stranger reach you. One simple approach is to use a name such as “Milo's owner,” then add a phone number and an email address you check. If the contact form has a notes or organization field, you can identify the pet there.
3. Choose a clear design. Use a dark code on a light background, and keep the contrast strong. You can adjust the colors or add a logo, but a plain code is often easier to scan when printed very small.
4. Save the generated QR code using the tool's available export option. Scan it with a phone, confirm that the preview shows the right contact details, and try saving the contact before you print it.

When you print the code, leave a clear margin around it. Do not crop the square or cover the small corner markers. A larger code is more dependable on a moving pet than a tiny one, so use the largest size that fits comfortably on the tag.

Choose what the QR code should do

Open a contact card

A contact QR code stores details that a phone can offer to save as a contact. This is useful if you want a finder to have your number even after they leave the tag. Put the pet's name in the contact name if that helps identify the card, and include a reachable guardian's number. If you have more than one contact, include only the details that are useful in an urgent situation.

Open a page with more pet information

If you want to include instructions such as medication needs or a second contact, a QR code for a web link can point to a page with those details. The page must be available online for the finder to open it, and the QR code itself does not protect the information. Anyone who scans it may be able to read the page. Avoid putting sensitive details, your home address, or information you would not want a stranger to see.

Use a contact card and a separate information page

A contact card is quick to save, while a page can hold more information. If you use both, keep the page short and put the most important way to reach you in the contact card. For help deciding what belongs in a contact QR code, see how to create a QR code for contact details.

Fix a QR code that will not scan

1. Increase the printed size. A code with a lot of contact details contains more small squares than a short link code. Print it larger and test it from the distance a person would hold a phone.
2. Restore strong contrast. Use a dark code against a light background. Avoid pale colors, busy patterns, and reflective surfaces that create glare.
3. Remove the logo or decoration. A logo can cover parts of the code and make scanning less reliable, especially when the code is tiny. Try a plain version if a phone struggles to read it.
4. Check the saved contact information. Scan the code again and review the preview before saving it. If a number or name is wrong, update the contact details and generate a replacement code.
5. Test the actual tag or label. Scan it after printing and attaching it. Curved surfaces, scratches, dirt, and glare can interfere even if the image scanned on your computer.

Where to put the code

A collar tag is convenient, but it can be scratched or turned away from the camera. You can also put a code on a carrier, travel crate, or pet's leash. Use a durable label or tag, and keep the phone number readable as ordinary text nearby if there is room. That gives someone a way to contact you if they cannot scan the code.

Check the QR code every few months and after changing phone numbers or email addresses. Replace the printed tag when the code is damaged or the contact details change.
