Learn when a crypto transfer needs a memo or destination tag, where to enter it, and what to do if it was omitted.
Why this matters
Some services use one blockchain address for many customers and identify each deposit with an additional memo, tag or destination tag. XRP commonly uses destination tags, while assets such as XLM, ATOM and others may use memo-style identifiers depending on the receiving platform.
The address moves funds to the service’s wallet; the secondary identifier tells the service which account or order should receive credit. A successful on-chain transaction can therefore remain uncredited when the required identifier is missing or incorrect.
Practical checklist
- Check the TrustChange order and receiving platform for both an address and a memo or tag.
- Copy each value into its matching field; never append the tag to the address unless explicitly instructed.
- Confirm the network, amount and identifier before sending.
- Save the order ID and transaction hash after payment.
- If the tag was omitted, contact the receiving service with proof instead of sending private keys.
Common mistakes
Do not assume a tag is optional because the wallet allows an empty field. Do not reuse a memo from an older deposit or confuse an order number with an on-chain tag. A support team may need manual evidence, and recovery is not guaranteed.
Bottom line
When a memo or tag is displayed, treat it as part of the destination. Verify it as carefully as the address and preserve the transaction details until the exchange is complete.
