The TAG/MEMO is a unique identifier assigned to each account that allows centralized cryptocurrency exchanges to identify a deposit and credit the appropriate account. By forgetting the MEMO, your transfer may not arrive at the destination until it's retrieved. Binance.US requires a tag/memo.

On the other hand, a wallet such as Trust wallet is a decentralized and does not require a Memo or Destination Tag to send tokens. You only need to input the wallet address correctly. Please read more here.
