How to Create a WhatsApp Click-to-Chat Link

There is an incredibly simple way to let anyone start a WhatsApp conversation with you without saving your number first. It is called a click-to-chat link, and WhatsApp provides it through a short URL format that works on every platform. Whether you run a small business, manage a community, or just want to make yourself easy to reach, these links are worth knowing about.

The Basic wa.me Link Format

WhatsApp's official click-to-chat URL follows this structure:

Replace 1234567890 with the full phone number in international format. Drop the plus sign, dashes, spaces, and parentheses. Just digits. For a US number like +1 (555) 867-5309, the link becomes:

When someone clicks this link on a phone with WhatsApp installed, it opens a chat window with that number pre-loaded. On a desktop browser, it opens WhatsApp Web or prompts to launch the desktop app. The person clicking does not need to have the number saved in their contacts.

Adding a Pre-Filled Message

You can take things a step further by pre-filling a message that appears in the text field when the chat opens. Append ?text= followed by your message:

For messages with spaces or special characters, you need to URL-encode them. Spaces become %20, and line breaks become %0A. Here is a more realistic example:

The recipient sees this message ready to send, but it is not sent automatically. The person still has to tap the send button, which means there is no risk of accidental messages flying off.

Where to Use Click-to-Chat Links

Once you have built your link, the places you can drop it are practically unlimited:

• Business websites -- Add a "Chat with us on WhatsApp" button that links directly to your support number. This is far more personal than a generic contact form, and response rates tend to be significantly higher.
• Social media bios -- Instagram, TikTok, and Twitter all let you put a link in your profile. A wa.me link turns your bio into a direct line of communication.
• Email signatures -- Place the link below your name and title. People who receive your emails can tap it and reach you on WhatsApp in two seconds.
• Printed materials -- Convert the link into a QR code for business cards, flyers, or product packaging. Most phone cameras will scan it and open WhatsApp directly.
• Online ads -- Facebook and Instagram ads can direct people to a WhatsApp chat instead of a landing page, which often leads to faster conversions for service-based businesses.

Creating Links Without a Phone Number

If you want to share a click-to-chat link without exposing your number, WhatsApp does not natively support that. The phone number is always part of the URL. However, you can use a URL shortener to mask the full link, or use WhatsApp Business's built-in short link feature, which generates a wa.me link tied to your business account automatically.

Common Mistakes to Avoid

A few pitfalls trip people up when building these links:

• Including the plus sign -- The URL should use wa.me/1234567890, not wa.me/+1234567890. The plus sign can cause issues in some browsers.
• Using local number format -- Always use the full international number. If you are in the UK and your number starts with 07, convert it to 44 followed by the number without the leading zero.
• Forgetting URL encoding -- Spaces and special characters in the pre-filled message must be encoded. An unencoded ampersand (&) will break the URL because browsers interpret it as a parameter separator.
• Testing only on desktop -- Always test your link on a mobile device too. The behavior differs between platforms, and mobile is where most WhatsApp conversations happen.

Best Practices for Pre-Filled Messages

Keep the pre-filled text short and specific. Something like "Hi, I am interested in your product" works better than a wall of text that the person might not want to send as-is. A good pre-filled message gives context to the recipient while still feeling natural enough that the sender does not feel compelled to rewrite it.

If you use these links for business, consider including a reference code or page name in the pre-filled message. For example: ?text=Hi%2C%20I%20saw%20your%20winter%20sale%20ad. This lets you track where incoming chats are coming from without any additional tools.

You can also create multiple links with different pre-filled messages for different purposes -- one for sales inquiries, one for support, one for partnerships -- and place each on the appropriate page or channel.
