Yes, it is possible to send a WhatsApp message to someone without having their contact information saved in your phone. There are a few different ways to do this:
Using WhatsApp Web/Desktop
The easiest way is to use WhatsApp Web or WhatsApp Desktop. To do this:
- Open WhatsApp on your computer browser or desktop application.
- Click on the “New Chat” button.
- Enter the full phone number of the person you want to message in the “To” field.
- Type your message and hit enter to send it.
As long as the person you are messaging has an active WhatsApp account with that phone number, they will receive your message even if you don’t have their contact information saved.
Using Click to Chat Links
WhatsApp also offers click to chat links that can be used to start a chat with someone without having their number saved. To generate a click to chat link:
- On your phone, open WhatsApp and tap on the More Options or Settings icon.
- Go to Settings > Invite via link.
- Tap on “Click to chat link.”
- Enter the phone number you want to message and tap create link.
- This will generate a URL that you can send to someone via another app to start a WhatsApp chat with you.
When the person clicks on that link, it will open a chat with your number filled in so they can immediately start messaging you on WhatsApp without having to save your contact first.
Using WhatsApp Business API
WhatsApp also provides a Business API that allows businesses to programmatically send WhatsApp messages to users who have not saved their number. This requires using the WhatsApp Business app and API. Here is how it works:
- You must have a WhatsApp Business account.
- Integrate the Business API into your business systems.
- When you want to message a new user, your program calls the API.
- The API initiates a conversation with the user you specify.
- You can then send messages to them via the API without needing their contact saved.
This is useful for businesses who want to reach new customers on WhatsApp automatically, such as for notifications, alerts, marketing, and more.
Using a WhatsApp Group Invite Link
You can also message someone without their contact by using a WhatsApp Group invite link. Group admins can create invite links that allow people to join a group chat via that link. Here’s how:
- In an existing WhatsApp Group, tap on the Group subject.
- Tap on Invite via link.
- Turn on the setting to generate a shareable group link.
- Send this link to someone via another channel.
- When they click the link, they will be added to the group where you can message them.
This allows you to message people in a group setting without their number saved already. However, they can always leave the group if they want.
Using a Local Business Listing
Some local businesses will list their WhatsApp number on their Google My Business listing or other directories. If you find a business this way, you can simply tap to chat with them on WhatsApp without saving their number first.
This allows customers to conveniently start a chat thread with businesses to ask questions or get more information before opting to call or visit the business.
