Before diving into the steps, it’s important to know that updating a contact’s phone number on your iPhone ensures that you have their latest information. This can be crucial for staying connected with friends, family, or colleagues. Let’s get started!

Step 1: Open the Contacts App or Settings

Open the Contacts app directly or go to Settings and scroll down to Contacts.

If you go through Settings, you will find additional options related to contacts, like accounts and importing SIM contacts, but for updating a number, opening the Contacts app directly is quicker.

Step 2: Select the Contact to Edit

Scroll through your contact list and select the contact whose phone number you want to update.

Remember that you can use the search bar at the top of the Contacts app to quickly find the person you’re looking for.

Step 3: Tap on Edit

Once you have the contact’s details on your screen, look for the Edit button, usually found in the top-right corner.

The Edit mode will allow you to change not only the phone number but also the contact’s name, email, ringtone, and more.

Step 4: Tap on the Phone Number

In Edit mode, tap on the phone number field that you want to change.

Ensure that you choose the correct number if your contact has multiple numbers listed.

Step 5: Enter the New Phone Number

Delete the old number and type in the new one.

Be careful to enter the number correctly to avoid any inconvenience later.

Step 6: Tap Done to Save the Changes

After entering the new number, tap Done. It’s usually in the upper-right corner of the screen.

Your changes will now be saved, and the contact’s information will be updated immediately.

After completing these steps, the contact’s new phone number will be updated in your iPhone’s contact list. The next time you try to reach them, your iPhone will use the updated number.
