The fastest way to add a contact on WhatsApp

Open WhatsApp and tap the Chats tab at the bottom. Look for the speech bubble with a plus sign in the bottom right corner and tap it. Type the person's name and phone number, then tap Create. WhatsApp will check if that number has a WhatsApp account — if it does, the contact appears in your chat list and you can message them right away.

You can also add someone by opening your phone's contacts app first, creating or editing a contact with their phone number, then opening WhatsApp. The contact will sync automatically and appear in your WhatsApp chat list within a few seconds.

A third method works if someone sends you their contact card: tap and hold the message, then select Add to Contacts. This saves their number to your phone and adds them to WhatsApp at the same time.

Key Takeaways

  • You can add a contact directly in WhatsApp by tapping the plus icon in the Chats tab and entering their name and phone number.
  • Contacts you create in your phone's contacts app will automatically appear in WhatsApp once the app syncs.
  • WhatsApp only shows contacts who have WhatsApp accounts — if someone's number is not registered with WhatsApp, they will not appear in your chat list.
  • You need the person's phone number to add them; WhatsApp does not let you search by username or email address.

Adding contacts from your phone's address book

The easiest way for most people is to add the contact to your phone first, then let WhatsApp find them. Open your phone's Contacts app, tap the plus sign to create a new contact, and enter the person's name and phone number. Save the contact.

Open WhatsApp and go to the Contacts tab — this is usually the second tab at the bottom. WhatsApp will show you all the contacts from your phone's address book who have WhatsApp accounts. Tap any contact to start a conversation. If someone you added does not appear, it means they do not have WhatsApp, or you entered their number in a format WhatsApp does not recognize.

What happens when you add someone who is not on WhatsApp

If you add a contact's number but they do not have WhatsApp, their name will not show up in your WhatsApp chat list. WhatsApp only displays contacts who have registered accounts with the service.

You can still send them a message — WhatsApp will let you type and send — but they will not receive it unless they read WhatsApp and register that same phone number later. If they do sign up after you have messaged them, your old messages will not appear in their chat history.

Adding contacts by scanning a QR code

WhatsApp lets you add someone using a QR code, which is faster than typing a phone number if you are in the same room. Open WhatsApp, tap Settings (or the three dots menu on some phones), then Account or Profile. Look for QR Code and tap it to show your code.

The other person opens WhatsApp, goes to the Contacts tab, and taps the QR code icon (usually in the top right). They point their camera at your code, and WhatsApp adds you to their contacts automatically. You can also save your QR code as an image and send it to someone by email or text, and they can scan it from their phone's photo gallery.

Adding contacts on different phone types

The steps are nearly the same on iPhone and Android, but the exact button locations differ slightly. On iPhone, the plus sign appears in the top right of the Chats tab. On Android, it is usually in the bottom right. Both phones sync contacts from your address book the same way.

If you use WhatsApp on a computer or tablet, you cannot add new contacts directly in the app — you have to add them to your phone first, then open WhatsApp Web or WhatsApp Desktop and they will appear automatically.

Why a contact might not appear after you add them

The most common reason is that the person does not have WhatsApp. Check that you entered their number correctly, including the country code if they live outside your country. Phone numbers need the plus sign and country code — for example, +1 for the United States, +44 for the United Kingdom.

If you entered the number correctly and they do have WhatsApp, try closing and reopening the app. Sometimes WhatsApp takes a minute or two to sync new contacts from your phone's address book. If they still do not appear after five minutes, restart your phone.

Frequently Asked Questions

Can I add someone to WhatsApp without their phone number?

No. WhatsApp requires a phone number to add a contact. You cannot search by username, email, or social media handle. If you do not have someone's phone number, you will need to ask them for it before you can add them.

What if I add someone but they have not added me back?

That is normal. Adding someone to your contacts does not notify them or add you to their contact list. They will only see you in their chats if they add your number themselves or if you message them first. When you message someone who has not added you, your message appears in their "Unknown Contacts" or "Message Requests" section until they add you.

Can I add a contact if I do not have their phone number saved?

Yes. In the Chats tab, tap the plus icon and type their name and phone number directly into WhatsApp. You do not have to save it to your phone's contacts first, though doing so is recommended so you do not lose the number.

Does adding someone on WhatsApp let them see my phone number?

Only if you message them. When you add someone to your contacts, they do not get notified and cannot see your number. Once you send them a message, they can see your number in their chat history and can add you to their contacts if they want to.

What is the difference between adding a contact and starting a chat?

Adding a contact saves their number to your phone and WhatsApp so you can message them anytime. Starting a chat without adding them lets you message someone whose number you have, but their name will not be saved. If you delete the chat, you lose their number unless you added them as a contact first.
