The basic steps work the same way on every phone

Adding a contact means storing someone's phone number, email address, or both in your phone's built-in address book so you can call or text them without typing the number each time. On an iPhone, you open the Contacts app (the icon that looks like a person's head and shoulders). On an Android phone, you open the Contacts app or the Phone app — both have a Contacts tab. Then you tap the plus sign or "Add Contact" button, type in the person's name and phone number, and save it. The contact then appears in your list alphabetically by last name.

The reason this matters is that once a contact is saved, your phone recognizes the person's number when they call or text you, and displays their name instead of just digits. It also lets you search for someone by name instead of scrolling through a list of numbers you may not remember.

Key Takeaways

  • Open your phone's Contacts or Phone app and tap the plus sign or "Add Contact" button to begin.
  • Type the person's name exactly as you want it to appear in your list, then enter their phone number in the field marked for phone numbers.
  • You can add an email address, home address, or notes in the same screen before saving, but only the name and phone number are required.
  • Once saved, the contact appears in your alphabetical list and your phone will display the person's name when they call or text you.

Adding a contact on iPhone

Open the Contacts app — it has a gray icon with a silhouette of a person. Tap the plus sign in the top right corner. A blank contact form appears with fields for first name, last name, phone number, and email. Type the person's first and last name in the name fields. Tap the phone number field and type their number, including the area code (the three digits at the start). If you know their email address, tap the email field and type it in. Then tap "Done" in the top right corner. The contact is now saved and appears in your alphabetical list.

If you want to add more information later — like a home address, birthday, or a note about how you know them — you can open the contact again by tapping their name in the list, then tap "Edit" in the top right corner. Make your changes and tap "Done" again.

Adding a contact on Android

Open the Contacts app or the Phone app and look for the Contacts tab at the bottom. Tap the plus sign or look for a button that says "Create Contact" or "Add Contact." A blank form appears. Type the person's name in the name field. Tap the phone number field and type their number with the area code. If you know their email, tap the email field and add it. Then tap "Save" at the bottom of the screen. The contact is now in your list.

Some Android phones also let you add a contact directly from the Phone app by tapping the keypad, typing the number, and then tapping the plus sign that appears. This method is faster if you already have the number in front of you and want to save it right away.

What to do if you have the number but not the name

If someone gives you their number but you are not sure how to spell their name or what to call them, you can still save the contact. Type whatever name makes sense to you — a first name only, a nickname, or a description like "Mom's friend Sarah." You can always edit it later once you have the correct spelling. The important part is that the phone number is saved accurately, because that is what your phone uses to recognize incoming calls and messages.

Double-check the number before you save it. A single wrong digit means the contact will not work when you try to call. If the person texts you after giving you their number, you can also save the contact directly from the text message — on iPhone, tap their number in the message and select "Create New Contact," and on Android, tap their number and select "Add to Contacts."

Organizing contacts with groups or labels

Once you have several contacts saved, you may want to organize them. iPhone lets you create groups within Contacts, though this is less common than on Android. Android phones often let you assign contacts to groups like "Family," "Work," or "Friends" when you save them. To do this on Android, tap the group field when you are creating the contact and select or type the group name. This makes it easier to find people later and to send messages to a whole group at once.

You do not have to use groups — your contacts will work fine in a straightforward alphabetical list. But if you have many contacts and want to find them faster, grouping them by relationship or workplace can save time.

Syncing contacts across devices

If you use multiple devices — a phone and a tablet, or you switch phones — you may want your contacts to appear on all of them. iPhone contacts sync automatically if you sign into the same iCloud account on both devices. Android contacts sync if you sign into the same Google account. This means when you add a contact on one device, it appears on the other within a few minutes. If your contacts are not syncing, check that you are signed into the same account on both devices and that sync is turned on in your settings.

If you ever switch to a different type of phone — from iPhone to Android or vice versa — your contacts can move with you. You can export your contacts from the old phone and import them into the new one, though the exact steps vary by phone model. Your phone's settings menu usually has an option for "Export Contacts" or "Backup Contacts" that walks you through this process.

Frequently Asked Questions

Can I add a contact without a phone number?

Yes. You can save just a name and email address if that is all you have. However, most people add a contact specifically to call or text them, so a phone number is usually the most important piece of information to include.

What happens if I save a contact with the wrong number?

Your phone will try to call or text that wrong number when you use the contact. Open the contact by tapping the name in your list, tap "Edit," fix the number, and tap "Done" or "Save." The contact will then use the correct number.

Can I add a contact from a text message or call?

Yes. On iPhone, tap the number in a text message or the caller's name on an incoming call and select "Create New Contact." On Android, tap the number in a text message and select "Add to Contacts," or tap the caller's number and select "Add to Contacts." This saves you from typing the number manually.

Do I need to include the plus sign or country code?

For calls and texts within your own country, no. Just type the area code and number. If you plan to call someone in another country, you can add the plus sign and country code at the start, but it is not required for most everyday use.

What is the difference between a contact and a favorite?

A contact is anyone you have saved in your address book. A favorite is a contact you mark as important so they appear at the top of your list or in a separate section for quick access. You can mark a contact as a favorite by tapping the star icon next to their name.
