How do I find the exchange that an address belongs to? I have an address that I have sent Bitcoin to but I forgot what exchange that address was for.

  • After you deposit it, normally it gets swept into a bigger wallet which I just google to find out. Also all the exchanges know each other's addresses so even if the big address doesn't appear in google, it's possible. Jun 7, 2019 at 22:26

It is basically impossible to identify who (whether it is an exchange or someone else) owns an address unless they announce that they own the address. You will not be able to figure out what exchange the address that you have belongs to by just looking at the address alone.

You will have to look elsewhere, and knowing the address is not really important. Look through your emails and think of the exchanges where you have made an account on. Only through other data that you have (e.g. your emails, saved login info, etc.) can you figure out what exchanges you have used and thus potentially deposited coins to. The address that you have is irrelevant.

    It's not impossible. You just have to look at other outputs claimed by the transactions that have claimed payments to that address. If you can match any of those to an exchange, you've got it. Nov 7, 2017 at 21:26
  • That assumes that the exchange has moved the coins and moved them in a transaction with inputs that are known to belong to the exchange. If they did not (and there is no guarantee that they did) then that method will not work.

  • It doesn't assume anything. You assumed things by saying it's impossible. My answer, however, makes no assumptions whatsoever. (Notice the "not" and the "if"?) Nov 7, 2017 at 21:32
  • The person was asking if there is a way. There is no "way". Could you luck out? Sure. Is there a set process? No.

  • Although "luck" is technically possible; it is so highly improbable as to be of no practical use. If you add to your answer showing the required process of luckily determining what exchange and address belongs to, that would help clarify things. Apr 17, 2018 at 12:37

Generally, it is difficult to impossible to find out whom an address belongs to. However, there are some sites that try to figure out whom addresses belong to by clustering transaction activity of well-known entities in the space. Since exchanges have a lot of transaction activity, it might actually be possible that your address turns up.

I can't vouch for accuracy or completeness of the data, but you might want to try to see whether the address is listed either on oxt.me or on walletexplorer.com to jog your memory.
