WhatsApp's official short-link format for click-to-chat, using wa.me followed by a phone number.
A wa.me link is the official short URL format WhatsApp provides for click-to-chat. It takes the form of wa.me followed by a business phone number in international format, and it can carry a pre-filled message as a query parameter so the conversation starts with text ready to send.
Because it uses WhatsApp's own domain, the wa.me link is reliable across devices and platforms and is the recommended way to share a click-to-chat link publicly. It works the same whether tapped on mobile or opened on desktop, routing to WhatsApp Web where appropriate.
Marketers use wa.me links in bios, ads, emails, and buttons as a clean, trusted entry point into a business chat.
