Forgot the memo or destination tag? What to do next
If you forgot the memo or destination tag when depositing crypto to an exchange, the coins have usually reached the exchange’s address but have not been credited to your account. In most cases only that exchange’s support can fix it, using the transaction ID and proof of your deposit. Here is what a memo or tag is, what to send support and how to never miss one again.
What is a memo or destination tag?
A memo or destination tag is a short piece of information attached to a transfer that tells the receiver, usually an exchange, which customer the deposit belongs to. Exchanges often receive coins for many customers at one shared deposit address, and the memo is the only thing that separates your deposit from everyone else’s.
A memo is not a password or a secret. It is a routing note that anyone can read on the blockchain, so never put personal information in it. A personal wallet address belongs to one person, which is why it usually needs no memo at all.
Destination tag, memo or comment: what each network calls it
The idea is the same on every network, but the name and the format change. On the XRP Ledger it is a destination tag, which is a whole number. On Stellar it is a memo, which can be text or a numeric ID. On TON the exchange asks for a comment, which it usually calls a memo.
If a deposit page shows both an address and a memo, tag or comment, both are required. The address brings the coins to the exchange; the memo brings them to your account.
| Network | Name of the field | Format | Who requires it |
|---|---|---|---|
| XRP Ledger | Destination tag | A whole number, digits only | Exchanges and services that share one address; an account can also make the tag mandatory |
| Stellar | Memo | Text or a numeric ID | Exchanges and services that share one address |
| TON | Comment (often called memo) | Short text, often a number or code | Exchanges and services that share one address |
What happens if you forget the memo?
If you forget the memo, the transfer itself usually succeeds: the coins reach the exchange’s shared address, but the exchange cannot tell whose they are, so nothing appears in your account. The funds are not destroyed; they are sitting in a wallet the exchange controls.
That also means only the exchange can fix it. A confirmed blockchain transfer cannot be reversed by anyone: not by you, not by the wallet you sent from and not by Waletifi. What remains is to ask the receiving exchange to find the deposit and credit it by hand.
Sent XRP without a destination tag?
XRP has one extra safety net. On the XRP Ledger, an account can require a destination tag on every incoming payment. If the exchange has turned this setting on, a payment without a tag is rejected instead of being lost, and your XRP stays in your account; at most the tiny network fee is spent.
If the setting is off, the payment goes through and you are in the usual missing-memo case. To see which one happened, look up the transaction ID in a block explorer for the XRP Ledger: a failed status means the XRP never left your account, while a successful one means it is at the exchange.
How do I get a deposit without a memo credited?
Contact the support of the exchange you sent to, through its official website or app only. These requests are handled by hand: they can take days or weeks, some exchanges charge a fee, and none can guarantee the result.
Before you open a ticket, gather everything that shows the deposit is yours:
- The transaction ID (TXID, or hash) of the transfer.
- The address you sent from.
- The exact amount and the coin you sent.
- The date and time of the transfer.
- A screenshot of the exchange’s deposit page showing the address and the memo you should have used.
Wrong memo, or sent to a personal wallet
A wrong memo is harder to fix than a missing one. If you entered a memo that belongs to someone else, the exchange may already have credited your coins to that customer, and getting them back depends on the exchange. Report it to support right away with the same details.
If you sent to a personal wallet, the memo usually does not matter. The address belongs to one person, so the coins are already in that wallet, with or without a memo. The same goes for withdrawing from an exchange to your own wallet: leave the memo field empty unless your wallet shows one.
Memo, address or network mistake: how they differ
These three mistakes look alike, but they end very differently:
Sent crypto on the wrong network?
- Missing memo: right address and right network, but no label. The coins are at the exchange, and its support is the one that can trace them.
- Wrong network: the coins moved on another blockchain. Whether they come back depends on who controls that address on that network.
- Wrong address: the coins went to someone else’s address, and only its owner can send them back.
Beware of paid “recovery services”
After a lost deposit, scammers often reach out in private messages or comments and offer to recover the funds for an upfront fee. These offers are scams: nobody outside the receiving exchange can credit a missing-memo deposit, and nobody can reverse a confirmed transfer.
Real support never asks for your recovery phrase or private key. Sharing a transaction ID is safe because it only points to public data, but your recovery phrase gives full control of your wallet.
Checklist: how to never forget the memo again
Waletifi supports XRP, Stellar and TON. Its “Review & confirm” screen shows the network, the memo and the network fee before you send, and the app warns you when you leave the memo empty for an exchange address. The deposit page is still the source of truth, so check these points before every deposit:
How to send crypto in Waletifi
- Copy both the address and the memo from the exchange’s deposit page, every time.
- Paste the memo into the memo, tag or comment field, never into the address field.
- Check that the network you send on is the one the deposit page names.
- Read the warning on the deposit page; if it says a memo or tag is required, the deposit will not be credited automatically without it.
- For a new exchange or a large amount, send a small test transfer first and wait until it is credited.
