The name of the friend of mine is A and I can see only the mutual friends that we have, not all his friends. The name of the person that I'm not friend with on Facebook but has 3 other mutual friends is B. I can't see his friends either, except his 3 friends we have in common. How to find out if A and B are friends?

  • "except his 3 friends we have in common". That list would include A if A and B were friends, wouldn't it?

You can see the relationship between two users by using their username or Facebook id.

Use the below link if you know the username:


Where USER1 is A and USER2 is B.

If you have Facebook id instead of username, use this link:


Where ID1 is A's Facebook id and ID2 is B's Facebook id.

This is the developer way.

    This doesn't give me a list, just the number and two example friends they have in common. But I have found a solution and posted it as an answer. Feb 26, 2017 at 0:35

Use the Message function, and ask A if they are connected to B.

    I would like to find another way.

Use https://searchisback.com/.

It will generate a search query that looks like this:
where ID1 and ID2 are the Facebook IDs of the queried users.
