What is a OKX memo or tag? Which assets need it and how should you verify it before transfer?

Many transfer problems are not caused by a wrong address but by an asset that also requires a memo or tag for correct crediting.

Who this guide is for

• Best for users making their first deposit or withdrawal or still unclear about extra transfer fields
• Not every asset needs a memo, but if the page asks for one it becomes mandatory
• A correct address alone is not enough when the token model also uses an extra identifier

Suggested path

1. First confirm whether the current asset and network require a memo, tag, destination tag or note field instead of checking only the address.
2. After copying the OKX address, review the extra identifier shown on the page and confirm where and how it should be filled.
3. Before the real transfer, run a small test if possible and keep a complete record of address, memo, network and TxID.
4. If the memo was missed or entered incorrectly, do not keep repeating transfers. Preserve the chain proof first and then follow the OKX recovery or support path.

Key checks

• asset requirement
• field location
• transfer review

FAQ

Does every transfer need a memo?

No. Only some assets and address models require it, but once OKX shows the field it must be entered correctly.

Can I reuse an old memo that I saved before?

Do not assume that. Confirm the current page still shows the same address and memo requirement.

Can funds be recovered after a missing memo?

It depends on the asset and platform process. Keep the TxID and screenshots first, then follow the official support flow.
