How to make a WhatsApp QR code for a rental apartment

Guests may need to ask about check-in, Wi-Fi, or a missing item, but typing a phone number is easy to get wrong. A WhatsApp QR code gives them a quicker way to open a chat with you from a welcome card or sign inside the apartment.

Use the QR Code Generator to make the code in your browser. You can choose WhatsApp as the QR content, then scan the finished code yourself before sharing it with guests.

Create the WhatsApp QR code

1. Open the QR Code Generator and choose the WhatsApp content type.
2. Enter the phone number registered with WhatsApp in international format. Include the country code, but leave out the plus sign, spaces, parentheses, and hyphens. For example, a US number might look like 15551234567.
3. If you want guests to start with a suggested message, use a message field if the generator provides one. Otherwise, create a WhatsApp chat link with the message included, then make a QR code from that link. The message is only prefilled, guests can edit it or delete it before sending.
4. Choose a dark code on a light background. You can add color or a logo, but keep the pattern clear and leave the blank margin around it unobstructed.
5. Save the QR code, then scan it with a phone camera. Confirm that it opens a chat with the correct number before printing or posting it.

Use the full number associated with your WhatsApp account. In some countries, a domestic number starts with a zero that is not included after the country code. Check the international form of your own number rather than guessing.

Choose what guests see

A direct chat with no suggested text

A basic WhatsApp QR code opens a chat with your number. This suits a general contact card, especially if guests may need to ask about many different things. It does not send a message automatically. The guest reviews and sends their own message.

A prefilled greeting

A suggested message can tell you which apartment the guest is contacting you about. For example, it might say, “Hi, I am staying in Apartment 2 and have a question.” Keep it short and avoid adding a door code, booking number, or other private detail. Anyone who scans the code can read the suggested text before sending it.

A personal number or a separate contact number

The chat link points to the WhatsApp number you enter. Guests may be able to see that number in the conversation, so do not use a personal number unless you are comfortable sharing it. If you prefer to keep personal and rental messages separate, use a dedicated number that is set up for WhatsApp.

Put the code where guests need it

Print the code large enough to scan from a comfortable distance. A small card on a table can use a smaller code than a notice guests need to scan from across the room. Keep the code square, with a clear light margin around every edge. Do not crop the margin when placing it in a design.

Place it near the information it supports, such as the Wi-Fi instructions, a welcome note, or the contact details for the host. Add a plain-language label next to it, such as “Scan to message your host on WhatsApp.” The label helps guests understand why the code is there, and provides a fallback if their camera does not recognize it.

Test a printed proof at its final size and in the lighting guests will use. Scan from the likely distance, and try more than one phone if possible. A code that works on a bright computer screen can be harder to scan after printing, especially if the ink is light, the paper is glossy, or a logo covers too much of the pattern.

Fix common scanning problems

1. Check the phone number. Scan the code and inspect the chat before sending a message. If it opens the wrong contact or no chat, recreate it with the correct international number, digits only.
2. Try a camera app. Open the phone's camera and point it steadily at the whole code. Some camera apps show a link prompt that you must tap. If the camera cannot read it, use a QR scanning feature in the phone's built-in tools.
3. Make the code easier to read. Increase its printed size, use a dark foreground on a plain light background, and keep the blank margin intact. If you added a logo or custom colors, remove them and test again.
4. Check WhatsApp availability. The link can open in a browser or prompt the guest to use WhatsApp. They need access to WhatsApp to continue the conversation. Ask them to open the link in WhatsApp or its web version if the phone does not switch apps automatically.
5. Replace an outdated print. The QR code contains the number and any included message. If you change the WhatsApp number or message, generate and print a new code, then remove old copies from the apartment.

Know what the QR code shares

A WhatsApp QR code is a shortcut to a chat, not a private messaging service or a way to hide your contact details. Anyone with a copy can scan it, and the number encoded in it is not secret. Avoid placing the code in a public listing if you only want current guests to contact you. A printed card inside the apartment gives you more control over who sees it.

Scan the final printed copy once more after placing it. This confirms both the destination and the real-world print quality before guests arrive.
