Where to find your blocked contacts
The location of your blocked contacts list depends on which device and app you're using. On most phones, blocked contacts live in your phone's settings rather than inside individual apps — though some apps like Facebook, Instagram, and email clients keep their own separate blocked lists.
On an iPhone, open Settings, scroll to Phone or Messages, and look for a "Blocked Contacts" or "Blocked" option. On Android, the path varies by manufacturer, but usually lives under Settings > Apps & Notifications > Phone or Messages, then a Blocked or Do Not Disturb section. Gmail, Outlook, and other email apps have their own block features buried in account settings or contact options.
The key thing to know: blocking someone in your phone's messaging app does not automatically block them on social media, email, or other platforms. Each service maintains its own list.
Key Takeaways
- Blocked contacts are stored in your phone's settings (iPhone and Android) or within individual apps like email and social media.
- Blocking someone in one app — like text messages — does not block them in another app like email or Facebook.
- You can unblock a contact at any time by finding them in your blocked list and selecting unblock or remove from blocked.
- Some phones show you a log of blocked calls and messages, while others straightforward prevent them from reaching you without notification.
How blocking works on iPhone
On iPhone, you can block contacts through the Phone app, Messages app, or FaceTime app — each maintains its own blocked list. To block someone in Messages, open the conversation, tap the contact name at the top, scroll down, and select "Block this Caller." To unblock, follow the same path and select "Unblock."
You can also block someone before they ever contact you. In your Contacts app, open the person's card, scroll to the bottom, and tap "Block this Caller." iPhone does not send a notification to the blocked person — calls and texts straightforward fail to go through, and the blocked contact will not know they are blocked unless they try to reach you and notice the silence.
To see your full blocked list on iPhone, go to Settings > Phone > Blocked Contacts, or Settings > Messages > Blocked Contacts. The list shows everyone you have blocked across all three apps in one place.
How blocking works on Android
Android phones vary by manufacturer, but the general path is Settings > Apps & Notifications > Phone or Messages, then look for "Blocked numbers" or "Blocked contacts." Some phones like Samsung add a "Block" option directly in the Phone app — open a contact or recent call, tap the three dots, and select Block.
Unlike iPhone, Android often shows you a notification when a blocked contact tries to reach you, depending on your phone model and settings. Some Android phones log blocked calls in a separate folder so you can see who tried to contact you without letting the call through.
To unblock on Android, go back to your blocked list, find the contact, and tap Unblock. The process is usually one or two taps.
Blocking contacts in email and social media
Email services like Gmail and Outlook have their own block features separate from your phone's blocked list. In Gmail, open an email from the person you want to block, click the three dots, and select "Block [name]." Blocked senders go to spam automatically, and Gmail will not notify them.
On Facebook, go to Settings & Privacy > Settings > Blocking, and type the person's name to block them. On Instagram, open the person's profile, tap the three dots, and select "Block." Twitter, TikTok, and other social platforms have similar options in their account settings or on individual profiles.
These blocks only affect those specific apps. Blocking someone on Facebook does not block their email or text messages.
What happens when you block someone
When you block a contact on your phone, calls and text messages from that number straightforward do not reach you. The blocked person typically sees their call go to voicemail or their text fail to send, but they do not receive a message saying they are blocked — they just experience silence.
On social media, blocking is more visible. A blocked person cannot see your profile, send you messages, tag you in posts, or find you in search. They may realize they are blocked if they try to visit your profile and see an error message.
In email, blocked senders' messages go straight to spam. They do not know they are blocked unless they check spam themselves or notice you never respond.
Unblocking and reblocking contacts
You can unblock a contact at any time by finding them in your blocked list and selecting unblock. On iPhone, go to Settings > Phone > Blocked Contacts, swipe left on the name, and tap Unblock. On Android, open your blocked list, find the contact, and tap Unblock.
Once you unblock someone, they can call, text, email, or message you again as if the block never happened. They will not receive a notification that you unblocked them. If you change your mind, you can block them again using the same steps.
Some people unblock temporarily to check if a blocked contact has tried to reach them, then reblock afterward. Your phone does not prevent this — you can block and unblock the same person as many times as you need to.
Recovering blocked messages and calls
Once a message or call is blocked, you cannot retrieve it from your phone's normal message or call history. However, some Android phones keep a separate log of blocked calls that you can view in your Phone app or a dedicated "Blocked" folder.
If you need to see what a blocked contact tried to send you, you will have to unblock them first. Unblocking does not restore old blocked messages — it only allows new ones through. Some email services like Gmail let you check your spam folder to see blocked emails before permanently deleting them.
If you blocked someone by mistake and want to see their old messages, unblock them, then search your message history for their name or number.
Frequently Asked Questions
Can a blocked contact tell they are blocked?
Not always. On phone calls and texts, a blocked person usually just sees their call go to voicemail or their text fail to send — they do not get a message saying they are blocked. On social media like Facebook or Instagram, they may realize they are blocked if they try to visit your profile and see an error. Email blocks are invisible unless they check spam.
If I block someone, do they see my old messages?
No. Blocking only prevents future contact. Old messages you already sent remain in their message history. On social media, blocking removes you from their followers and hides your profile, but does not delete past conversations or posts they can still see screenshots of.
Do I need to block someone on my phone and on social media separately?
Yes. Blocking someone in your phone's Messages app does not block them on Facebook, Instagram, email, or any other platform. Each service maintains its own block list. If you want to block someone everywhere, you need to block them in each app individually.
What if I blocked someone and forgot who it was?
Your blocked contacts list shows the phone number or name of everyone you blocked. On iPhone, go to Settings > Phone > Blocked Contacts. On Android, go to Settings > Phone > Blocked numbers. The list does not show why you blocked them, only who is on the list.
Can I block a number that is not in my contacts?
Yes. You can block any phone number, even if it is not saved as a contact. When an unknown number calls or texts, tap the three dots or info button and select Block. The number will be added to your blocked list even if you never saved their name.
