What unblocking a contact means

Unblocking a contact means removing the block you placed on someone's phone number, email address, or messaging account so they can reach you again. When you block someone, they cannot call you, text you, email you, or see your messages or posts — depending on which app or service you blocked them on. Unblocking reverses that restriction.

The steps to unblock someone are different on every device and app. A contact blocked on your iPhone works differently from one blocked on Android, and blocking someone on Facebook is completely separate from blocking their phone number. This guide covers the most common places people block contacts and how to undo each one.

Key Takeaways

  • Blocking happens on individual apps and devices, so you may need to unblock someone in multiple places if you blocked them everywhere.
  • On iPhone, unblock a phone number or contact in the Phone app or Messages app; on Android, use the Phone app or your default messaging app.
  • Email blocking works differently on Gmail, Outlook, and other providers — each has its own unblock list you must access separately.
  • Social media blocking (Facebook, Instagram, TikTok) is separate from phone or email blocking and requires going to your blocked accounts list on that platform.
  • Once you unblock someone, they can contact you when ready, but they cannot see old messages or calls you blocked while they were blocked.

Unblocking a phone number on iPhone

On iPhone, blocked phone numbers live in the Phone app. Open the Phone app, tap the Recents tab at the bottom, find the contact you want to unblock, and tap the "i" icon next to their name. Scroll down and tap "Unblock this Caller." The contact can now call or text you.

If you do not see the contact in Recents, open the Contacts app instead. Find the person, tap "Edit" in the top right, scroll to the bottom, and tap "Unblock this Contact." You can also go directly to Settings > Phone > Blocked Contacts and swipe left on the name you want to unblock, then tap "Unblock."

Unblocking a phone number does not restore old text messages or voicemails that arrived while they were blocked — those are permanently deleted. The person can send new messages starting when ready after you unblock them.

Unblocking a phone number on Android

On Android, the steps depend on which phone manufacturer you have and which messaging app you use. Most Android phones have a Phone app (sometimes called Dialer) where you can manage blocked numbers. Open the Phone app, tap the three-line menu icon, go to Settings or Blocked Numbers, and look for a list of blocked contacts. Tap the contact and select "Unblock."

If you blocked someone in your default messaging app (like Google Messages, Samsung Messages, or another app), open that app instead. Go to Settings or Blocked Contacts within the app and find the person's name. Tap and hold it, then select "Unblock" from the menu that appears.

Different Android phones and apps arrange these menus differently, so if you cannot find the blocked list in the obvious place, search the app's settings for the word "block" or "blocked." Once you unblock the number, calls and texts can come through again.

Unblocking someone in email

Email blocking works separately on each email provider. On Gmail, open an email from the person you want to unblock, click the three-dot menu icon, and select "Unblock [name]." You can also go to Settings > Filters and Blocked Addresses, find the blocked address in the list, and click the delete icon next to it.

On Outlook (including Hotmail), open an email from the blocked contact, click the three-dot menu, select "Block," and then "Unblock." Alternatively, go to Settings > Mail > Junk Email, click the "Blocked Senders" tab, find the address, and click "Remove from list."

On Apple Mail, blocking and unblocking happens through your email provider's website, not the Mail app itself. Log into your email account online, find the blocked senders list in settings, and remove the address from there. Once you unblock an email address, messages from that person will arrive in your inbox instead of the spam or blocked folder.

Unblocking someone on social media

Social media blocking is separate from phone and email blocking. On Facebook, go to Settings > Privacy > Blocked People, find the person's name, and click "Unblock." On Instagram, go to Settings > Blocked Users, find the account, and tap "Unblock." On TikTok, go to Settings > Privacy > Blocked Accounts, find the user, and tap "Unblock."

On Twitter/X, go to Settings > Privacy and Safety > Mute and Block > Blocked Accounts, find the account, and click "Unblock." On Snapchat, go to Settings > Blocked, find the person, and swipe left to unblock them.

When you unblock someone on social media, they can see your profile again, send you messages, and see your posts — but they cannot see content you posted while they were blocked. They also cannot see old messages you sent them before the block.

What happens after you unblock someone

Once you unblock a contact, they can reach you through that specific app or service when ready. A phone number unblocked on your iPhone can call you right away. An email address unblocked on Gmail can send you messages that land in your inbox. A social media account unblocked on Facebook can message you and see your profile.

However, unblocking does not restore anything that happened while they were blocked. Text messages, voicemails, emails, or direct messages sent to you while the block was active are gone — they were not stored anywhere. The person does not receive a notification that you unblocked them, though they may notice they can reach you again.

If you block the same person again later, the process is the same as the first time. You go back to the same menu and select "Block" instead of "Unblock."

Unblocking someone on a shared device or account

If you share a phone, computer, or email account with someone else, unblocking a contact affects everyone who uses that device or account. On a shared family iPhone, unblocking a number in the Phone app unblocks it for all users. On a shared Gmail account, unblocking an email address unblocks it for anyone with access to that inbox.

If you need to block or unblock someone but do not want others on the device to know, you will need your own separate account or device. Some phones allow you to set up a separate user profile or guest account, but blocking and unblocking are still visible to anyone with access to the main account settings.

Frequently Asked Questions

Can someone tell if I unblocked them?

No. The person does not receive a notification when you unblock them. They may notice they can call or message you again, but they have no way to know exactly when you unblocked them or that you had blocked them in the first place.

If I unblock someone, will they see old messages I sent before I blocked them?

No. Messages, calls, and emails sent before the block are not affected by unblocking. They can only see and receive new messages sent after you unblock them. On social media, they cannot see posts you made while they were blocked.

Do I have to unblock someone in every app, or just one?

Blocking is separate on each app and service. If you blocked someone's phone number on your iPhone, that does not block their email or their Facebook account. You have to unblock them separately in each place where you blocked them.

What if I forgot where I blocked someone?

Check the most common places: the Phone app (for phone numbers), your default messaging app (for text messages), your email provider's website (for email addresses), and the social media platforms you use. Each one has a blocked list in its settings. If you still cannot find them, they may not be blocked anywhere.

Can I unblock someone temporarily and then block them again?

Yes. You can unblock and block the same person as many times as you want. Each time you unblock, they can contact you when ready. Each time you block, they cannot reach you again. There is no limit to how many times you can change this.
