What a wa.me Link Is
wa.me is WhatsApp’s own address for “Click to Chat”. A link like https://wa.me/919876543210 opens a chat with that number on the phone or computer of whoever taps it, without them saving your number first.
Type your number above with the country code chosen for you, and the tool builds the link in the official format. Add a ready message if you want, then copy the link, download its QR code or copy a button for your website.
