The iPhone keeps a blocked-contact list that you can review when you are not sure whether a person or phone number was blocked earlier. On current iOS versions, app-specific settings are grouped under Settings > Apps.
Quick steps
- Open Settings.
- Tap Apps and choose Phone.
- Open Blocked Contacts.
- Scroll through the list of blocked people and numbers.
- Remove an entry only if you want to unblock it.
The list applies across Apple communication apps
Blocking a contact affects normal communication through Phone, Messages, and FaceTime for that identity. You may also be able to reach the same blocked list through the settings for Messages or FaceTime, depending on the iOS version.
A contact can have more than one address
Someone may have several phone numbers and email addresses saved on one contact card. If communication is still blocked after you remove one entry, check whether another number or email for that person remains on the list.
Blocking is different from spam filtering
Silence Unknown Callers, carrier spam protection, Focus modes, and third-party call-filtering apps can prevent or silence calls without placing the caller on the blocked-contact list. If a number is not shown as blocked, check those features next.
What happens when you unblock
Removing a person from the list allows future calls and messages to come through normally. It does not recover calls or messages that were prevented while the person was blocked.
One more detail worth knowing
How to See Blocked Calls on iPhone Ever wondered if someone you blocked tried to call you? Although iPhones don't keep a regular log of blocked calls, there are still ways to uncover this information. By using a few easy steps, you can access your blocked list and manage your call history effectively.
How to confirm the change
After you finish view blocked numbers/contacts, repeat the action that originally brought you to this guide. Check the visible setting or real-world result rather than assuming the change took effect. If the result differs from the steps above, return to the relevant menu and look for a carrier, account, device, or app-specific control before changing unrelated iPhone settings.
Open the blocked contacts list
On current iOS versions, blocked-contact controls can be reached through the settings for Phone, Messages, FaceTime, or related communication apps. Phone settings are generally under Settings > Apps > Phone. Review the blocked list to see the numbers and contacts currently prevented from reaching you.
Blocked and filtered calls are different
A number does not have to be on the blocked list to be silenced or filtered. Unknown-caller screening, Focus, carrier spam protection, and third-party call-filtering apps can all affect incoming calls. Check those features separately if a caller is missing from the blocked list.
