The fastest way to add a contact to WhatsApp

You can add a new contact to WhatsApp in two ways: create the contact in your phone's address book first, then open WhatsApp and it will appear automatically, or add them directly within WhatsApp itself. The phone's address book method is simpler if you plan to text or call that person outside WhatsApp too. The in-app method is faster if you only need them in WhatsApp.

Both methods take less than a minute. The contact must have WhatsApp installed on their phone and an active phone number for either method to work.

Key Takeaways

  • You can add contacts through your phone's address book, where they will automatically appear in WhatsApp once saved.
  • You can also add contacts directly in WhatsApp by tapping the new chat button and entering their phone number manually.
  • The contact must have WhatsApp installed and an active phone number for you to message them.
  • On Android, you can also scan a QR code to add someone, which is useful if you do not know their phone number.
  • Once added, the contact will appear in your WhatsApp chat list and you can start messaging immediately.

Adding a contact through your phone's address book

This method works on both iPhone and Android. Open your phone's Contacts app (called Contacts on iPhone, Contacts or People on Android depending on your phone brand). Tap the button to create a new contact — usually a plus sign or "Add contact" button. Enter the person's name and phone number, then save.

Open WhatsApp. The new contact will now appear in your chat list. If you do not see them immediately, pull down on the chat list to refresh it. You can now tap their name to start a conversation.

This method is best if you want the contact saved in your phone's main address book as well, so you can call or text them outside WhatsApp later.

Adding a contact directly in WhatsApp on iPhone

Open WhatsApp and tap the Chats tab at the bottom. Look for the pencil-and-paper icon or "New Chat" button in the top right corner and tap it. A list of your existing contacts will appear. Tap "New Contact" at the top of that list.

Enter the person's name and phone number, including the country code (for example, +1 for the United States, +44 for the United Kingdom). Tap Save. WhatsApp will check if that number has WhatsApp installed. If it does, you can start messaging right away. If not, you will see a message saying the contact does not have WhatsApp yet.

The contact will now appear in both your WhatsApp chat list and your phone's address book.

Adding a contact directly in WhatsApp on Android

Open WhatsApp and tap the Chats tab. Look for the floating button with a pencil and paper icon or a plus sign, usually in the bottom right corner. Tap it and select "New Chat." A list of your existing contacts will appear.

Tap the plus sign next to "New Contact" at the top. Enter the person's name and phone number with the country code. Tap Save. WhatsApp will check if that number has WhatsApp installed. You can start messaging immediately if they do.

On Android, you also have the option to scan a QR code instead. If someone gives you their WhatsApp QR code, tap the three-dot menu in the top right, select "Settings," then "Linked Devices" or "QR Code," and scan their code. This adds them without needing their phone number.

What to do if the contact does not have WhatsApp

If you enter a phone number and WhatsApp says the contact does not have WhatsApp, they either do not have the app installed or they are not using that phone number with WhatsApp. You can still save them in your phone's address book, but you will not be able to message them through WhatsApp until they install it.

You can check back later by opening the chat with that contact — WhatsApp will notify you when they join WhatsApp. Alternatively, you can ask them directly to install WhatsApp so you can message them.

Adding contacts from a group or message

If someone messages you in a WhatsApp group, you can add them as an individual contact. Open the group, tap the person's name at the top of the screen, and look for an option to "Add to Contacts" or a plus sign next to their name. Tap it and confirm.

You can also add someone by long-pressing their message in any chat, then selecting "Add to Contacts" from the menu that appears. This method saves their number directly to your phone's address book and WhatsApp at the same time.

Frequently Asked Questions

Do I need the person's phone number to add them to WhatsApp?

Usually yes, but on Android you can scan their QR code instead if they provide one. The QR code method does not require you to know their phone number. On iPhone, you must use a phone number.

Will the person know I added them to WhatsApp?

No. Adding someone to your contacts does not send them a notification. They will only know you have their number if you message them or they see you in their own contact list.

Can I add someone without their phone number?

On Android, yes — you can scan their QR code. On iPhone, you need their phone number. There is no other way to add someone without one of these two pieces of information.

What if I enter the wrong phone number?

You can edit the contact by opening the chat, tapping their name at the top, and selecting "Edit." Change the phone number and save. WhatsApp will check the new number and update the contact.

Can I add a contact who does not have WhatsApp yet?

Yes, you can save their number in your phone's address book or in WhatsApp. You just will not be able to message them until they install WhatsApp. WhatsApp will notify you when they join.
