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

Published on Aug 22, 2023Updated on Oct 30, 20242 min read271

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.

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