Is RMA number the same as eBay return ID

[nubley2010]

I need to return a damaged item and have been issued with rerurn label and package slip by eBay. It asks me to write the return RMA number on the label but despite much Googling, I'm still not sure where to find this. I have a 10-figure 'eBay return ID'. Is that the same thing?

Some sellers activate this feature as it stops ebay automaticaly issuing the wrong type of label.

You can ask seller but number is usualy supplied in a message to you, if not advised of it then it is probably not needed just seller controlling return postage and can be left blank or ebay number used.
