You can decline a request without the person knowing, or block them entirely
When someone sends you a friend request on Facebook, you have three choices: accept it, ignore it, or decline it. Declining a request straightforward removes it from your inbox — the person does not get a notification that you declined, and they cannot see that you rejected them. Blocking is stronger: it prevents that person from seeing your profile, messaging you, or sending you another request, and they will not know you blocked them (though they may figure it out if they try to visit your profile).
Most of the time, declining is enough. You decline a request once and it is gone. Blocking is for people who keep sending requests, who you want to avoid entirely, or whose access to your information concerns you. This guide covers both actions and when to use each one.
Key Takeaways
- Declining a friend request removes it from your inbox without notifying the person or leaving a record they can see.
- Blocking prevents someone from seeing your profile, messaging you, or sending you another request, and they cannot undo it on their end.
- You can decline a request from your friend requests list, from a person's profile, or from a message they sent you.
- If you block someone by mistake, you can unblock them later, but they will not know you blocked them in the first place.
- Blocking is permanent until you unblock — the person cannot send you requests or see your posts even if you were once friends.
How to decline a friend request
Open Facebook and look for the friend requests icon — it looks like a person with a plus sign, usually in the top right of the screen. Tap or click it to see your list of pending requests. Find the person whose request you want to decline.
Next to their name, you will see two buttons: one says "Confirm" (to accept) and one says "Delete Request" or shows an X. Click the delete or X button. The request disappears from your list when ready. The person will not receive a notification, and the request will not appear in their sent requests — it straightforward vanishes from both sides.
You can also decline a request from someone's profile page. Visit their profile, and you will see a button that says "Respond to Request" or "Delete Request". Click it and choose decline or delete. The result is the same: the request is gone, and they do not know you declined it.
How to block someone on Facebook
Go to the person's profile page. At the top right of their profile, you will see three dots (a menu icon). Click or tap those dots. A menu will appear with several options, including "Block". Click "Block".
Facebook will ask you to confirm. It will tell you that blocking prevents this person from seeing your profile, messaging you, and sending you friend requests. Click "Block" again to confirm. The block is now active.
You can also block someone from your friend requests list. Find their request, click the three dots next to their name, and select "Block". Or, if they have already sent you a message, you can block them directly from the message — open the conversation, click the three dots at the top, and select "Block".
What happens when you block someone
Once you block someone, they cannot see your profile, your posts, your photos, or your friends list. They cannot message you or see messages you sent them before the block (those conversations disappear from their inbox). They cannot send you a friend request. If you were already friends before you blocked them, the friendship is removed.
The person will not receive a notification saying "You have been blocked." However, if they try to visit your profile or search for you, they will see that your profile is not available to them, which may tip them off. They cannot undo the block on their end — only you can unblock them.
Blocking is not the same as unfriending. If you straightforward unfriend someone, they can still see your public posts and send you a message request. Blocking cuts off all contact and visibility.
When to decline versus when to block
Decline a request if you do not know the person, are not interested in being friends, or just do not want to accept right now. Declining is low-key — there is no record, no notification, and if you change your mind later, they can send another request. Use decline for acquaintances, distant connections, or people you straightforward do not interact with.
Block someone if they are harassing you, if they keep sending requests after you have declined, if you feel unsafe, or if you want to may support they cannot contact you at all. Blocking is permanent until you unblock, and it is the right choice when you need a hard boundary. Use blocking for people who make you uncomfortable or who you want completely out of your Facebook experience.
How to unblock someone later
If you block someone by mistake or change your mind, you can unblock them. Go to your settings by clicking the downward arrow or three horizontal lines in the top right corner of Facebook. Select "Settings and Privacy", then "Settings".
On the left side, click "Blocking". You will see a list of all the people you have blocked. Find the person you want to unblock and click "Unblock" next to their name. Confirm when Facebook asks you to. They are now unblocked.
Unblocking someone does not automatically make you friends again or restore old messages. It straightforward removes the block, so they can now see your profile and send you a friend request if they want to. They will not be notified that you unblocked them.
Blocking on mobile versus desktop
The steps are nearly identical on the Facebook app for iPhone or Android and on a computer. On mobile, tap the three dots on someone's profile or in a conversation to find the block option. On desktop, click the three dots in the same places. The menu looks slightly different depending on your device, but the block and decline buttons are always there.
One difference: on mobile, your friend requests list is accessed through the menu icon (three horizontal lines) at the bottom right of the app. On desktop, it is the person-with-plus icon at the top. Once you find your requests, the decline and block buttons work the same way on both.
Frequently Asked Questions
Will the person know I declined their friend request?
No. When you decline a request, Facebook does not send them a notification. The request straightforward disappears from their sent requests list. They will not see that you declined — they will only notice if they check and realize their request is gone.
Can someone send me another friend request after I decline?
Yes. Declining a request does not prevent them from sending another one later. If you want to stop them from sending requests, you need to block them instead.
What is the difference between declining and blocking?
Declining removes one request with no notification. Blocking prevents all future contact — they cannot message you, see your profile, or send requests. Blocking is permanent until you unblock; declining is temporary and they can try again.
If I block someone, can they still see messages I sent them before the block?
No. Once you block someone, all previous messages between you disappear from their inbox. They cannot see the conversation history or any messages you sent before the block took effect.
Can I block someone without them knowing?
They will not receive a notification that you blocked them. However, if they try to visit your profile or search for you, they will see that your profile is unavailable, which may make them suspect they are blocked.
