Why do I need to fill in tags (tag/memo) when I withdraw or deposit certain cryptos?

Tag (tag/memo) is an unique digital string used to identify deposit address. It ensures the funds are credited to the correct address. OKX distributes different tags to users’ deposit addresses of certain cryptos requested by the network. Tag exist in pairs, one for each deposit address. You need to fill out both the deposit address and tag/memo before submitting a request. If this is not done, the funds may not be credited to the correct address.

Note: deposit tag/memo are typically 7–8 digits long. Please refer to the tag/memo number displayed on the deposit page and enter it exactly as shown.

For example, you can find both the deposit address and tag/memo on the deposit page in the screenshot below:

How do I fill in the tag/memo?

To withdraw crypto that requires a tag or memo, follow these steps:

1. Open the OKX App, then go to Assets > Withdraw crypto, and select the crypto you want to withdraw

2. Select Exchanges or wallets and your preferred Network

3. Complete the withdrawal details including the tag/memo
   Note: it's necessary to fill in both the withdrawal address and the tag, otherwise, the withdrawal will be lost.

4. Then, submit the request and complete the necessary password or verification steps.

Important note:

• If you’re withdrawing to a saved address from your address book, the Tag/Memo field may not appear, as it was already saved when the address was added.

• If the Tag/Memo is entered incorrectly, the funds may not be credited successfully. In this case, please click the Get help button below to submit feedback and contact our support team.
