How to Make a Link in Bio for WhatsApp (Free wa.me Link and QR Code)
A WhatsApp link in bio works in two directions. One link lets people tap from your Instagram, TikTok or email straight into a chat with you. The other puts a web link on your WhatsApp profile so people who already message you can find your shop or booking form. Both are free, and so is a QR code for your number. Here is each step in WhatsApp's own menu wording, plus the mistakes that stop a link from opening.
Quick answer
To make a WhatsApp link in bio, type https://wa.me/ followed by your full phone number in international format, with no plus sign, leading zeros, spaces, brackets or dashes, for example https://wa.me/15551234567. Add ?text= and a URL-encoded message to pre-fill the chat. Paste that link into your bio, or turn it into a QR code that people can scan to message you.
1. Create your wa.me click-to-chat link
WhatsApp's click to chat lets anyone open a chat with you without saving your number, as long as the number has an active WhatsApp account. Use https://wa.me/ followed by your full number in international format: country code first, and no plus sign, international dialling zeros, brackets, spaces or dashes. A US number written +1 (555) 123-4567 becomes https://wa.me/15551234567. A UK mobile written 07700 900123 drops the leading zero and becomes https://wa.me/447700900123. Open it on your own phone once before sharing it.
2. Add a pre-filled message
A pre-filled message tells you where the person came from and saves them wondering what to say. Add ?text= after the number, then your message in URL-encoded form, where spaces become %20. For example, https://wa.me/15551234567?text=Hi%20I%20saw%20your%20bio opens the chat with 'Hi I saw your bio' ready to send, and the customer can still edit it. A link with only ?text= and no number opens a contact list instead, so always include your number.
3. Use the WhatsApp Business short link
WhatsApp Business creates a short link for you automatically. Go to the Tools tab, tap the menu icon, then Short link. From there you can copy the link, send it to customers, and turn on a default message for people who open it. Opened in a web browser, the short link first shows a page with your business information and a 'Continue to chat' button. A short link and a wa.me link both work in a bio, so pick one and use it everywhere.
4. Put a website link on your WhatsApp Business profile
WhatsApp Business profiles have a public website field alongside your business name, address, category, description and email. Go to the Tools tab, tap Profile, tap the website field, update it and tap Save. Personal profiles are built around your name, photo and About text, so Business is the dependable way to show customers a clickable website. WhatsApp says it is still testing some profile updates, so fields may look slightly different on your version; keep the app updated.
5. Make a QR code for your WhatsApp number
In the app, open Settings and tap the QR code next to your name, then share or save it. On WhatsApp Business you can also go to Tools, Short link, View QR Code, then Share code, and set a default message of up to 140 characters. Or paste your wa.me link into a free generator such as onesol.io/qr-code-generator and download the image. That code points at your public link, so it opens in any phone camera and works as long as your number stays the same.
6. Point your profile link at one page
Your WhatsApp profile link should lead to one page that holds everything else. A free OneSol link-in-bio page at onesol.io/yourname can list your chat button, catalog, prices, socials and an order or booking form, and you can change the buttons anytime without touching WhatsApp. OneSol forms need no sign-in from the person filling them in and accept file uploads up to 5 MB, handy for photo-based orders. Selling downloads such as guides or templates? OneSol delivers those files instantly after payment.
7. Where to put your WhatsApp link
Put the link wherever people look for a way to reach you: your Instagram, TikTok, X or Facebook bio, your email signature, your website's contact page and your Google Business Profile, which WhatsApp's help center explains how to link. Print the QR code on packaging, receipts, flyers or a market stall sign. For websites, WhatsApp offers an official 'Chat on WhatsApp' button in green or white, currently in English only. A OneSol digital business card can carry the same chat link for people you meet in person.
8. Why your WhatsApp link is not working
Most broken links come down to the number. If the chat won't open or says the number is invalid, check for a plus sign, leading zero, spaces, dashes or a missing country code, and confirm the number is registered on WhatsApp. If the pre-filled message is cut off, a character such as &, # or a space wasn't URL-encoded. If WhatsApp's in-app camera won't read your printed code, that camera only scans official WhatsApp QR codes, so scan a wa.me code with the phone's normal camera.
9. Keep your link safe and up to date
Anyone with your link or QR code can message you, so think about where it appears, especially if it is your personal number. WhatsApp advises sharing your QR code only with people you trust, because it can be forwarded. You can reset your WhatsApp QR code if it spreads too far, but the old code then stops working, so reprint anything you handed out. Settings, then Privacy, controls who sees your profile photo and About. Many sellers simply use a separate business number.
