What a Destination Memo Does Before You Send Crypto
A destination memo or tag helps an exchange match a crypto deposit to your account when many customers share one wallet address. Here’s how to use it safely.

A 10-digit destination tag can tell an exchange which customer should receive an XRP deposit sent to a shared address. It is an extra piece of routing information attached to a crypto transfer, often called a memo, tag, or destination tag depending on the network.
The address gets the transaction to the platform’s wallet; the memo helps its system credit the right account. If you are also comparing how assets travel between blockchains, read this guide to how relay bridges move crypto between chains. A bridge moves assets across networks; a destination memo identifies a recipient within a service.
Why does a crypto transfer need a destination memo?
A memo is needed when a receiving service uses a shared wallet address for deposits. The blockchain records a transfer to that address, while the service uses the memo to identify which customer’s balance to update.
Think of the address as the destination building and the memo as the recipient’s account reference. Without that reference, the transfer may reach the service’s wallet but remain unmatched to your account.
Some networks support this extra field as part of a transaction. XRP uses destination tags, while Stellar and other networks use memos. The exact name and format depend on the currency and the receiving platform.
A memo is not the same as choosing a network. The network determines where the asset is sent; the address identifies the destination on that network; and, when required, the memo tells the service which account should receive credit. A relay bridge handles a different routing problem by moving assets between chains.
When do you need a tag or memo?
You need one when the receiving platform shows a memo or tag as required for that specific deposit. Requirements vary by asset and service, so check the deposit screen each time rather than relying on a previous transfer.
Centralized exchanges often use shared deposit wallets, which is why they may ask for an extra identifier. A self-custody wallet usually gives you an address controlled by your own keys, so there is often no exchange account to distinguish with a memo. Still, follow the receiving wallet’s instructions: some address formats or services have their own requirements.
The deposit page should provide the address and, when needed, the tag or memo. Copy both fields exactly. A memo may be numeric or alphanumeric, and a valid-looking value is not necessarily the right one for your account.
How do you send crypto with a destination memo?
Use the receiving platform’s current deposit instructions, then enter the address and memo in the matching fields in your sending wallet. Follow this sequence:
- On the receiving platform, select the asset and network you intend to use. Open its deposit details and check whether a tag or memo is required.
- Copy the deposit address and the memo separately. If you use a QR code, confirm that the wallet has captured both details when the platform requires them.
- In the sending wallet, choose the same asset and network. Paste the address into the address field and the memo or tag into its designated field.
- Check the asset, network, address, memo, and amount before confirming. For an unfamiliar destination, a small test transfer can help verify the setup before you send more.
Do not paste a memo into the address field or treat it as optional when the receiver marks it required. The sending wallet may accept a transaction without a memo, even though the receiving service needs it to credit your account.
What happens if the memo is missing or wrong?
The transfer may still be recorded on the blockchain, but the receiving platform may not automatically assign it to your account. An incorrect memo can point to a different account reference, while a missing memo leaves the deposit without the identifier the service expects.
That can delay crediting, and recovery is not guaranteed. If you have already sent a transfer with a missing or incorrect memo, save the transaction ID and contact the receiving platform’s support team. They may ask for the asset, network, amount, address, and other details to investigate.
A destination memo is a small field with a narrow job: it connects an on-chain deposit to the right account inside a service. Check the receiver’s instructions, match each value to its field, and verify the details before sending.
