Noticed when trying to do a ripple to ethereum exchange it did not work since the sending address does not have a tag number associated which is needed from the site I am sending the ripple from.

So could not complete the transaction.

Hello, regular customer!
The tag is already included in the x-address, and there is no need to enter it

If your wallet does not support x-type of addresses, on xrpscan.com you can enter the x-address there, and see the r-address and tag.
You can always write to our support, we will help you with any questions.
Best regards,

Think big. Exchange wisely.
This is of interest to me after over a nearly two years later!
I tried sending ripple from another exchange to a wallet address last night and I provided all information needed to do the transaction via xrp:
XRP deposit address and destination tag
The exchange just wrote the tag in the note and did not include it in the transaction as it was documented by myself before submitting it.
If I knew about x-type addresses I would of sent it this way if the wallet supported it on their platform.
Then I wouldn't be without my rather large transaction of ripple needing to be processed after all security measures have been fulfilled by the operator of the wallet.
