How to Chat With an Unknown Number on WhatsApp

Send a WhatsApp message without saving the contact on Android, iPhone, and desktop.

You can chat with an unknown number on WhatsApp without saving it to your contacts. The easiest way is a direct WhatsApp message link, the official wa.me format that opens a chat with any valid number.

Send a WhatsApp message without saving the number

Open WADirectSend, enter the number, and optionally type a pre-filled message.
Tap Send on WhatsApp to open the official chat link.
WhatsApp opens the conversation. No contact saved on your phone.

This works for any one-time chat: marketplace sellers, delivery riders, support lines, or business inquiries. You stay in control of your contact list.

Open the link in Chrome or your default browser.
