When depositing certain cryptocurrencies to an exchange, you need to fill in a field called "MEMO" in addition to the wallet address. Many beginners don't understand what MEMO is or even skip it entirely, resulting in deposits not arriving and assets seemingly "disappearing." This article explains in detail what MEMO means, how it works, and what to do if you forget to include it.
What Is a MEMO?
A MEMO (also called Memo Tag, Destination Tag, or Note Tag) is an additional identifier used by certain blockchain networks during transfers. It's essentially a string of numbers or letters that helps the recipient identify which user a transfer belongs to.
Why Is MEMO Needed?
Some blockchains (like XRP, XLM, EOS, ATOM, etc.) are designed so that exchanges use a single shared address to receive all user deposits. Different MEMOs are then used to distinguish "does this deposit belong to Alice or Bob?"
Analogy: Imagine a building with only one street address (wallet address), and the MEMO is the apartment number. If you mail a package with only the building address but no apartment number, the mailroom won't know which resident it belongs to.
Which Coins Require a MEMO?
The following major cryptocurrencies typically require a MEMO when depositing to exchanges:
| Coin | MEMO Name | Format |
|---|---|---|
| XRP (Ripple) | Destination Tag | Numbers only |
| XLM (Stellar) | Memo | Numbers or text |
| EOS | Memo | Numbers or text |
| ATOM (Cosmos) | Memo | Numbers or text |
| BNB (BEP2 chain) | Memo | Numbers |
| HBAR (Hedera) | Memo | Numbers |
| TON | Memo/Comment | Numbers |
Common coins that don't need MEMO: BTC, ETH, USDT (ERC20/TRC20/BEP20), BNB (BEP20), etc. Each user gets a unique deposit address for these coins, so no additional identifier is needed.
Where Do I Get My MEMO?
The MEMO is provided by the exchange on the deposit page, displayed alongside the deposit address.
Steps to get your MEMO on Binance:
- Go to Binance's deposit page
- Select the coin (e.g., XRP)
- Select the network
- The page displays both the "Deposit Address" and "MEMO/Tag"
- Copy both for your transfer
Note: Different coins have different MEMOs, and even the same coin may have different MEMOs on different exchanges. Always re-confirm before each deposit.
What Happens If I Forget the MEMO?
If you transfer without including the MEMO:
Sending to an exchange: The assets arrive at the exchange's master address, but the exchange doesn't know which user to credit. The assets aren't lost but won't appear in your account automatically.
How to resolve:
- Contact exchange customer support
- Provide the following information:
- Transaction Hash (TXID)
- Sending address
- Deposit amount
- Your account information
- After verification, support will manually credit the assets to your account
- Processing typically takes 3-7 business days
Sending to a personal wallet: If transferring to a personal wallet (not an exchange), MEMO usually isn't required because you control the address directly. However, some wallet apps may still ask for one.
What If I Enter the Wrong MEMO?
Entering the wrong MEMO is more troublesome than forgetting it:
- If the MEMO happens to belong to another user, the assets may be incorrectly credited to someone else's account
- The exchange usually detects the anomaly and freezes the transaction
- Contacting support with complete information can usually resolve it
- Processing may take longer
Safety Tips
Although MEMO is just a simple tag, omitting or mistyping it causes real problems:
- If the deposit page shows a MEMO, you must fill it in: Don't skip it hoping for the best
- Copy the MEMO directly from the exchange: Don't type it manually — errors are easy to make
- Double-check both MEMO and address: Verify after pasting
- Screenshot your deposit information: Including address and MEMO, for reference when contacting support
- Different exchanges have different MEMOs: Don't use Exchange A's MEMO on Exchange B
- Test with a small amount first: Confirm both MEMO and address are correct before transferring larger amounts
Register on Binance to get your dedicated deposit address and MEMO, or download the Binance App (iOS users refer to the iOS installation guide) for convenient mobile operations.
Do all cryptocurrencies require a MEMO?
No. Most cryptocurrencies (like BTC, ETH, USDT) don't need a MEMO. Only chains that use a shared address model (like XRP, XLM, EOS) need MEMOs to distinguish users. The deposit page will clearly indicate whether one is required.
Are MEMO and Tag the same thing?
Essentially yes. Different chains and exchanges use different names for this field: XRP calls it Destination Tag, XLM calls it Memo, and some exchanges simply call it Tag or Memo. The function is identical — an additional identifier for the recipient.
Do I need a MEMO when transferring to a personal wallet?
Usually not. MEMO is primarily an exchange mechanism for distinguishing different users. Personal wallets don't need user differentiation since you control the address directly. But if the wallet app provides a MEMO field, adding a custom note is harmless.
Can I change my MEMO?
Exchange-assigned MEMOs are typically fixed and cannot be modified by users. Just get the latest MEMO from the exchange before each deposit. If the exchange updates the MEMO, old ones may become invalid.
