When you wish to deposit XRP into your Blockchain Exchange account you will notice a unique XRP Tag will appear on the deposit screen. This tag is used to ensure that your deposit makes it into your exchange account without delay.
Each exchange account has a unique 10 digit XRP tag, so it's important that you only use the tag assigned to your account or you risk depositing your XRP into the wrong account.
IMPORTANT: You must include both your XRP wallet address , and the XRP tag associated with your Blockchain Exchange account. Failure to do this will result in significant delays, or the potential loss of your XRP funds completely.
If you did not include your Destination Tag then please submit a support ticket here and our team will do the best we can to help you.
