Block a phone number on your iPhone

For: iPhone

Last checked October 14, 2026 against official help from Apple. Written for iOS 26 and iOS 27.

If one number won't leave you alone, you can block it. Calls and texts from that number stop reaching you.

This page is for you if

A blocked caller can still leave a voicemail, but your iPhone won't tell you about it. They aren't told that you blocked them.

Step 1: Open your recent calls
Open the Phone app. Tap Calls or Recents at the bottom. Which one you see depends on how your Phone app is set up.
Step 2: Tap the number
Tap the number you want to block. If you see an Info button (i) next to it, tap that instead.
Step 3: Block it
Scroll down and tap Block Caller. Some versions call it Block this Caller. If your iPhone asks you to confirm, tap Block Contact.

Step 1: From a text
In Messages, open the conversation. Tap the name or number at the top. Scroll down and tap Block Caller.
Step 2: From your contacts
In the Phone app, tap Contacts, tap the person, then tap Block Contact.

To unblock someone, open Settings, tap Apps, then Phone, then Blocked Contacts. Tap Edit, tap the delete button next to the person, then tap Unblock. On iOS 26, Apple also lists blocked contacts under Settings, Privacy & Security, Blocked Contacts.
Scammers switch numbers often, so blocking one number won't stop them all. To quiet calls from numbers you don't know, see how to stop spam calls on iPhone.
