How to Add a Phone Number to the iPhone Contact List

Updated July 20, 2017

The iPhone comes with a pre-installed Contacts application that acts as an electronic phone book, allowing you to add phone numbers, e-mail addresses and mailing addresses for friends and family members. The Contacts application is most commonly used for storing phone numbers and can hold up to 2,000 numbers before it begins to affect the phone's processing speeds. Adding a phone number to your iPhone Contacts is simple and takes just a few moments to complete.

Click on "Contacts" to open the application.

Click on the "+" symbol in the upper right-hand corner of the screen. This will bring up the "New Contact" form.

Assign the contact a name. Your iPhone will store contacts alphabetically by first name or last name, depending on your chosen settings.

Enter your contact's phone number. You can designate types of phone numbers--mobile, home, work--on the line below where the number is entered.

Enter any additional information you would like to store for this contact, including an e-mail address, fax number or mailing address. You also have the option to attach a photo to the contact or select a custom ringtone.

Click "Done" and your contact will be added to your contact list. Repeat the process when you want to add a new contact.


When you receive a call or text message, an option will appear in the top right-hand corner of your screen to "Add to Contacts." This is a convenient shortcut to adding contacts. If you have contacts stored in your Apple computer "Address Book," add them to your iPhone by connecting your phone to the computer with a USB cable and following the on-screen instructions in iTunes.


A contact is not saved to your iPhone until you complete the process and click "Done." Be certain not to exit the Contacts application after hitting the "Save" button or your contact information will be lost.
