Memo and tag fields on exchange deposits: why a missing line of digits strands your coins
Some networks require a memo or destination tag so an exchange can credit the right account. What these fields do, which deposits need them and how to recover calmly if you forgot to include one.

Most deposits only need an address. A few networks work differently: the exchange uses one shared address for many customers and tells them apart with an extra field, called a memo, tag, comment or payment ID depending on the network. If you send coins to the right address but leave that field empty or fill it incorrectly, the coins reach the exchange but not your account. Recovery is sometimes possible but slow and never certain. This guide explains how to recognise deposits that need a memo, how to fill it correctly on Binance, OKX, Bybit or Bitget, and what to do if something goes wrong.
Recognising deposits that need a memo
When you open the deposit page and choose a coin and network, the exchange shows the address and, if needed, a separate memo or tag field, often with a warning that both are required. Read the whole page rather than copying only the address. The same coin can need a memo on one network and not on another, so check again whenever you change networks. If the deposit page shows a memo, assume the deposit will not be credited without it.
Filling the field on the sending side
The sending wallet or exchange must also support a memo field for that network. Look for it on the withdrawal form; it may be hidden under an optional or advanced section. Copy the memo exactly, without spaces, and check it digit by digit. If the sending platform does not offer a memo field for that network, do not send; choose a different network or a different route. For a first deposit, send a small amount and wait for it to be credited before sending the rest.
If the memo was missing or wrong
Do not send more coins to try to fix the problem. Collect the transaction ID, the amount, the time, the address used and the memo you intended to use. Then open a request through the official help centre of the receiving exchange; most have a dedicated form for deposits without a memo or with an incorrect one. Be patient and keep all communication inside official channels. Anyone who contacts you privately offering to recover the funds is almost certainly trying to steal more.
Building the habit
Save each memo next to its address in your notes or address book so you never rely on memory. Before every deposit on a memo network, read the deposit page warning again, because exchanges occasionally change addresses or memo formats. A short pause before pressing send costs a few seconds and prevents the most frustrating kind of lost deposit.

Scenario checkpoint
- Read the full deposit page and look for a memo or tag field whenever you change networks.
- Confirm the sending wallet offers a memo field for that network before starting the transfer.
- Send a small test deposit with the memo and wait for it to be credited before the rest.
- Contact the receiving exchange through its official form with the transaction ID if a memo was missed.
