How to see blocked numbers on iPhone

On iOS 18 and later: Settings → Apps → Phone → Blocked Contacts.

On iOS 17 and earlier: Settings → Phone → Blocked Contacts.

Apple moved per-app settings under an "Apps" section in iOS 18, which is why older instructions send you to a menu that no longer exists. If you can't find either path, pull down on the Settings home screen and search for "Blocked" — that jumps straight there on every recent version.

The same list is reachable from Settings → Apps → Messages → Blocked Contacts and Settings → Apps → FaceTime → Blocked Contacts. These are three doors into one list, not three separate lists.

Entries show a contact name if the number is in your address book, and a bare number if it isn't. That's the only distinction the list makes — there's no timestamp, no note about which app you blocked from, and no count of how many times they've tried to reach you.

If you blocked a number that was never saved as a contact, it appears as a raw number with no other context. This is worth knowing before you start unblocking: iOS gives you nothing to jog your memory about why a given number is on the list.

The list can be long if you've been tapping "Block this Caller" on spam for years. It isn't sorted by date added — it follows your contacts ordering, with unsaved numbers grouped separately.

Two ways, both from the Blocked Contacts screen:

1. Swipe left on the entry and tap Unblock.
2. Tap Edit in the top corner, then the red minus button next to the entry, then Unblock.

Unblocking takes effect immediately and restores calls, texts, and FaceTime all at once — you can't unblock one channel and keep the others blocked. There's no confirmation dialog on the swipe method, so it's easy to unblock the wrong row on a long list.

To add a number to the list from this screen, tap Add New… and pick a contact. You can only add saved contacts this way; to block a number that isn't in your address book, do it from the recent-calls list in the Phone app instead.

A blocked caller isn't told they're blocked. From their side, the call typically rings once and then goes to your voicemail — the same thing they'd hear if your phone were off or you declined.

They can still leave a voicemail, and it still reaches your phone. It just doesn't notify you. Open Phone → Voicemail and scroll to the bottom for a Blocked Messages section — those recordings sit there until you delete them. Most people never look, which is why "I blocked them and they still left a message" comes as a surprise.

Blocked text messages are different: they're discarded, not stored. There's no blocked-messages folder in Messages, and nothing to recover later.

The iPhone block list only knows about specific numbers you added. It won't help with three common cases:

• Numbers you never blocked. Spam usually rotates numbers, so blocking each one is a treadmill. Settings → Apps → Phone → Silence Unknown Callers is the blunter tool: it sends every number not in your contacts, recent outgoing calls, or Siri suggestions straight to voicemail.
• Carrier-level blocking. AT&T ActiveArmor, Verizon Call Filter, and T-Mobile Scam Shield keep their own separate block lists inside their own apps. A number blocked there will not appear in Settings, which is the usual explanation for "this number is blocked but it isn't in my list."
• Blocked at the network, before your phone. Some spam is filtered by the carrier before your iPhone ever sees it. Nothing about that appears anywhere on the device.

Blocking works fine for a personal phone, where a missed call from a stranger costs you nothing. On a business line the maths inverts — the same aggressive filtering that stops spam also silences the new customer calling from a number you've never seen.

That's the trade-off that block lists can't solve: you're choosing between answering everything and screening everything, with no way to tell which unknown number is the customer. Answering every call and sorting afterwards is the only approach that doesn't lose business, and it's the reason answering services exist at all.
