Adding someone on WhatsApp starts with their phone number. Open New chat > New contact, enter their name and number, and save. Depending on your settings, you can keep the contact exclusively in WhatsApp or sync it to your phone’s address book.

You can also save the number through your phone’s Contacts app. If WhatsApp has access to that contact and the number is registered on WhatsApp, you can find the person and start a conversation.

  • ➕ Add inside WhatsApp: New chat > New contact, enter details, then Save.
  • 🛠️ Troubleshooting: confirm they use WhatsApp, verify number + country code, update the app; Android: Refresh.

How to Add Someone on WhatsApp on Android?

You can add a new contact directly in WhatsApp without opening your phone’s Contacts app.

  1. Open WhatsApp and go to the Chats tab.
  2. Tap the New chat button, then select New contact.
  3. Enter the person’s name and phone number. Include the country code if you are adding an international number.
  4. If WhatsApp displays a Sync contact to phone option, turn it on to save the contact in your phone’s address book too. Leave it off to keep the contact only in WhatsApp.
  5. Tap Save and follow any remaining prompts.
  6. Return to New chat, search for the contact, and tap their name to start messaging.

Already saved the number in your phone’s Contacts app? Search for the person in WhatsApp’s new-chat list. If they do not appear, check the number and WhatsApp’s contact permissions.

How to Add Someone on WhatsApp on iPhone

Add the person from WhatsApp’s Chats screen, then choose where to save their contact details.

  1. Open WhatsApp and select Chats.
  2. Tap the New chat icon, then select New contact.
  3. Enter the person’s name and phone number, including the country code for an international number.
  4. If a Sync contact to phone option appears, choose whether to also save the contact in your iPhone’s address book.
  5. Tap Save or Done, depending on the screen displayed.
  6. Open New chat, find the contact, and select their name to start a conversation.

If you added the person through Apple’s Contacts app, WhatsApp needs access to that contact to display it. With limited contact access enabled, you may need to add the new person to the contacts shared with WhatsApp.

How to Add Someone on WhatsApp With a Phone Number

Use the phone number associated with the person’s WhatsApp account. Their work number or another saved number may not be the one they use for WhatsApp.

  1. Open WhatsApp and select New chat > New contact.
  2. Enter the person’s name and phone number.
  3. For an international number, use +, followed by the country code and the remaining number in the correct international format.
  4. Save the contact, then find their name in New chat to start a conversation.

1. Check the country code

For example, a French number written as 06 12 34 56 78 becomes +33 6 12 34 56 78.

Formatting rules vary by country. If you are unsure, ask the person to share their number in international format rather than guessing which digits to remove.

2. What if WhatsApp offers an invitation?

Check the number with the person before sending an invitation. They may use WhatsApp with a different number, or the number you entered may contain a mistake.

Saving someone’s number does not register them on WhatsApp. They need an account associated with that number before you can message them there.

How to Save a Contact From an Existing WhatsApp Chat

If someone has already messaged you, you can save their number from the conversation.

  1. Open the chat with the unsaved number.
  2. Tap the phone number at the top to open the contact information.
  3. Select the option to add or save the contact. The wording may vary by device.
  4. Choose Create new contact, or add the number to an existing contact if it belongs to someone already in your address book.
  5. Enter or confirm the person’s name.
  6. Choose whether to sync the contact to your phone if that option appears, then save.

Check the number before adding it to an existing contact to avoid attaching a conversation to the wrong person.

How to Add a Contact on WhatsApp Web or Windows

WhatsApp supports adding contacts through WhatsApp Web and the Windows desktop app, so you can save someone’s details while working on your computer.

  1. Open WhatsApp Web or the WhatsApp Windows app and sign in to your account.
  2. Click New chat.
  3. Select New contact if the option is available.
  4. Enter the person’s name and phone number, including the correct country code.
  5. Choose whether to sync the contact to your phone if prompted.
  6. Save the contact, then search for their name to open a conversation.

If New contact is missing, update the Windows app or reload WhatsApp Web. You can also add the contact from WhatsApp on your main phone.

These instructions apply to Web and Windows. The Mac desktop app does not currently offer the same contact-creation functionality.

Why is My New Contact Not Showing in WhatsApp?

A missing contact does not always mean the number was saved incorrectly. Check the number, account, and contact-access settings before adding it again.

Problem What to check or try
The contact does not appear when you search Confirm that you saved the contact in the WhatsApp account you are currently using. Search by phone number as well as by name.
The number is not recognized Ask the person to confirm the number they use for WhatsApp. Check for missing digits, typing errors, or an incorrect country code.
A phone contact is missing on Android Open your phone’s Settings > Apps > WhatsApp > Permissions > Contacts and allow access if you want WhatsApp to use your phone contacts.
A phone contact is missing on iPhone Open Settings > Apps > WhatsApp > Contacts. If access is limited, include the new contact in your selection, or choose Full Access if preferred.
WhatsApp offers an invitation instead of a chat Verify that the person has a WhatsApp account registered with that exact number. Saving a number does not create a WhatsApp account for its owner.
The contact appears in WhatsApp but not in your phone’s Contacts app It may have been saved only in WhatsApp. Open the contact’s details and check the phone-sync option if you also want it in your address book.
The details still do not update Close and reopen WhatsApp, and check for app updates. Avoid repeatedly creating the same contact, which can leave you with duplicates.

👉 For international numbers, confirm the full format with the contact. For example, the French number 06 12 34 56 78 becomes +33 6 12 34 56 78. Number-formatting rules can differ by country.
