Unfortuantely as with all untagged Phalaenopsis orchids you can never know for sure what it is. Even if it looks identical to something else it could be something different.
We had a discussion here about the whole issue of most NoID's never being able to have an exact name.

What I like to do is find something similar then give it a name almost, but not quite the same, with a note on the tag to say it's actually a NoID.
NoID's are just as pretty as those with names and as long as you know enough to care for it that's all you need. This one will have pretty standard Phalaenopsis care, so no need to worry about an exact name.
