How to Unblock a Number on iPhone (iOS 26 & Older) 2026

If you blocked someone in a moment of frustration, or blocked a delivery, bank OTP or family number by mistake, undoing it takes about a minute. This guide shows how to unblock a number on iPhone in iOS 26, where Apple moved the blocked list under Privacy & Security, and on iOS 18 and earlier. It also covers unknown numbers, email senders, FaceTime and Mail, Mac and iPad sync, what happens after you unblock, and a troubleshooting checklist for when calls or texts still don't arrive.

Quick answer: On iOS 26, open Settings → Privacy & Security → Blocked Contacts. Tap Edit, tap the delete button next to the number, then tap Unblock. Faster options: swipe left on the number and tap Unblock, or tap the contact and choose Unblock Contact. Unsaved numbers live under the Unknown entry. On iOS 18 or earlier, use Settings → Phone → Blocked Contacts instead (unblocking in Phone also unblocks Messages, FaceTime and Mail).

The steps below follow Apple's own pages: Block phone numbers, contacts, and emails on your iPhone or iPad, Prevent contacts from communicating with you on iPhone, Report spam and block senders in Messages, Manage unknown callers on iPhone and the Personal Safety guide Block, screen, and filter communications.

Unblock vs Silence Unknown Callers vs Screen Unknown Senders vs Focus

People often mix up a true block with settings that only silence or filter. If someone "can't reach you" but they aren't on your blocked list, one of these is usually the reason:

If you only need to stop spam from rotating numbers, blocking one line at a time is the wrong tool — use Screen Unknown Callers or Call Filtering instead. Our guide on how to block a number on iPhone covers those options in detail.

How to unblock a number on iPhone in iOS 26

In iOS 26, Apple centralized the blocked list for Phone, Messages, FaceTime and Mail under Privacy & Security.

1. Open the Settings app.
2. Tap Privacy & Security.
3. Tap Blocked Contacts.
4. Tap Edit.
5. Tap the delete button next to the contact or number you want to unblock.
6. Tap Unblock.

Apple's iPhone User Guide also lists two quicker options in the same list:

• Tap the contact, scroll down and tap Unblock Contact.
• Swipe left on a number and tap Unblock.

Unblock a number that isn't saved in Contacts

Numbers and email addresses you never saved are grouped as Unknown in the blocked list.

1. Go to Settings → Privacy & Security → Blocked Contacts.
2. Tap the Unknown entry.
3. Swipe left on the number and tap Unblock, or tap Edit, tap the delete button and tap Unblock.

Tip: once it's unblocked, save the number to Contacts with a clear name (for example "Bank OTP" or "Courier"). Saved numbers aren't treated as unknown callers, so Screen Unknown Callers and Screen Unknown Senders won't hide them again by mistake.

Unblock from a contact card

If the person is still in Contacts and shows as blocked:

1. Open Contacts (or Phone → Contacts) and open their card.
2. Scroll to the bottom and look for Unblock Contact (wording can also appear as unblock options after you open Blocked Contacts and tap their name).
3. Or go to Settings → Privacy & Security → Blocked Contacts, tap their name, then Unblock Contact.

How to unblock a contact on iOS 18 and earlier

On older versions there's no single Privacy & Security list. Each app that can block has its own Blocked Contacts screen in Settings, but Apple says unblocking someone in one of them unblocks them in all four apps:

• Phone: Settings → Phone → Blocked Contacts
• FaceTime: Settings → FaceTime, then under Calls tap Blocked Contacts
• Messages: Settings → Messages, then under SMS/MMS tap Blocked Contacts
• Mail: Settings → Mail, then under Threading tap Blocked

Open any of them, tap Edit, tap the delete button next to the number and tap Unblock.

Not sure which version you have? Go to Settings → General → About and look at iOS Version.

How to see blocked numbers on iPhone

To review everyone you've blocked in iOS 26, go to Settings → Privacy & Security → Blocked Contacts. Saved contacts are listed by name; unsaved numbers and emails sit inside the Unknown entry. On iOS 18 or earlier, use Settings → Phone → Blocked Contacts.

Apple suggests checking this list first if you're not getting someone's messages. A contact can also look blocked when you never blocked them — that happens when they share a phone number or email with someone who is on the list. Open their card in Contacts and compare details with your blocked list.

Unblock email senders, FaceTime and Mail notes

In iOS 26, email addresses you blocked in Mail appear in the same Blocked Contacts list, and you unblock them the same way. On iOS 18 and earlier, use Settings → Mail → Blocked.

Apple says:

• Email from a blocked sender is moved to Trash, so check Trash for anything that arrived while they were blocked.
• Email blocking works across all your Apple devices signed in to the same Apple Account.
• Outgoing phone calls and emails to blocked contacts are still allowed — blocking mainly stops incoming contact from them.
• When you block in Messages, that contact is also blocked in Mail, Phone, FaceTime, Calendar and other Apple apps. Unblocking reverses that shared block.

FaceTime callers you blocked are on the same list. After you unblock, new FaceTime audio and video calls from that Apple ID / number should ring normally again (unless Screen Unknown Callers / Silence Unknown Callers is still filtering unsaved numbers).

Unblock someone on a Mac or iPad (iCloud sync)

Apple says a block applies on every Apple device signed in to the same Apple Account, so you may also want to confirm the list on your Mac or iPad:

• iPadOS 26: Settings → Privacy & Security → Blocked Contacts (same as iPhone).
• macOS 26: Apple menu → System Settings → Privacy & Security → Blocked Contacts.
• macOS 15 or earlier: in Messages, choose Messages → Settings, click iMessage, then Blocked. FaceTime and Mail have their own Blocked lists in their settings.
• iPadOS 18 or earlier: manage blocked contacts through Phone (if available), FaceTime, Messages or Mail settings, same idea as older iPhone.

If one device still behaves as if the person is blocked, open that device's blocked list and confirm the number is gone, and that you're signed in to the same Apple Account.

What happens when you unblock someone

Once a number is unblocked:

• New calls, FaceTime calls and messages from that person reach you normally again (subject to Focus, screening and carrier settings — see troubleshooting below).
• Messages they sent while blocked are not delivered later. Apple says messages from a blocked number aren't delivered, so they won't suddenly appear in your inbox after you unblock.
• While blocked, they could still leave voicemail, but you weren't notified. Check your voicemail list for anything left during that time.
• The other person isn't notified that their calls or messages were blocked, and Apple doesn't describe any alert when you unblock someone.

Side effects of blocking that don't auto-restore

Apple's Personal Safety guide lists a few side effects of blocking. Apple doesn't say these switch back on when you unblock, so check them yourself:

• Find My location sharing: sharing your location with that person stops when you block them. In iOS 26 Apple notes they will not get a notification that you stopped sharing; on older iOS they may. If you want them to see your location again, share it again in the Find My app.
• Emergency contact: if the person was one of your emergency contacts, blocking removed them. Add them back in the Health app under Medical ID if you want them there.
• Shared calendars, notes and invitations: if you were sharing other information, use Safety Check (Settings → Privacy & Security → Safety Check on supported iOS versions) to review what's still shared. Add the email tied to their Apple Account to the contact card if you need to stop future sharing invitations.
• Family Sharing: if the blocked contact is in a Family Sharing group with you, they may still see the location of devices associated with you in Find My devices even after a people-location share was stopped.

Unblocked but still not getting texts or calls?

If someone is off your blocked list and their messages or calls still don't come through, work through this table in order:

Extra checks Apple calls out:

1. Spam folder recovery: In Messages, open Filters → Spam, tap a message that isn't spam, tap Not Spam, then Move to Messages.
2. Unknown Callers / Spam lists in Phone: Settings → Apps → Phone → Call Filtering. In Recents you can use the Filter button to open Unknown Callers or Spam lists.
3. Other devices and apps: Look at the blocked list on your iPad or Mac too. Apps like WhatsApp, Instagram and Telegram keep their own block lists.

Typical scenarios

• You blocked a courier or bank number by accident: unblock it from the Unknown entry in Blocked Contacts, then save it to Contacts so screening doesn't hide the next OTP.
• A friend says their messages aren't arriving: check Blocked Contacts first, then Unknown Senders and Spam in Messages, then Hide Alerts on that chat.
• You made up with someone after blocking them: unblock them, then reshare your location in Find My and re-add them as an emergency contact if needed.
• Helping a parent who blocked a family number: check the blocked list on the parent's own iPhone. Your phone's list doesn't affect theirs unless you share an Apple Account.
• Too many spam calls after unblocking: try Screen Unknown Callers or Call Filtering instead of blocking one number at a time — covered in how to block a number on iPhone.
• "How to unblock calls iPhone" searches: if calls still go to voicemail after unblock, the fix is usually Screen Unknown Callers → Never (or save the number), not another trip through Blocked Contacts.

Verdict for each type of user

• On iOS 26: use Settings → Privacy & Security → Blocked Contacts. It's the one place for calls, texts, FaceTime and email.
• On an older iOS version: use Settings → Phone → Blocked Contacts. Unblocking there also unblocks Messages, FaceTime and Mail.
• Unsaved numbers: look under the Unknown entry and swipe left to unblock, then save to Contacts.
• Still missing messages or calls: check screening, Focus, Hide Alerts, Spam/Unknown filters, dual SIM and third-party apps before blaming the block list again.
• Mac / iPad users: confirm the same Apple Account and the device's own Blocked Contacts list.
