Why is it required?
Generally speaking, a Memo or Destination Tag is almost exactly the same thing. They are unique identification codes used to determine the receiver of a transaction. Centralized exchanges like Binance and Coinbase, utilize this system because it is easier for them to manage a single address for every user on their platform. The Memo or Destination Tag will be used to correctly route the transfer of tokens to the intended receiver.
Important
It is the users responsibility to determine the Memo or Destination Tag of the receiving wallet. Without the correct information, your tokens might not be credited to your account or it could even get lost.
Where to find it?
On the receiving platform, the Memo or Destination Tag will be shown on the Deposit screen. Here are some examples from Binance Exchange.
