I have had 100% success doing identify missions from Newland (only tested individual missions).
I have completed several missions, including missions with my main, lvl 51 Adventurer, and a lowbie, a lvl 5 'crat. I even did one last night where I didn't kill all the monsters and still got a token.
I have gotten a token, the cash, and the reward from every identify mission I have gotten from Newland. I suspect that other Neutral terms will probably work too, since the Neutral terms seem to be using different code (note: you will only get 2 missions to choose from at the Neutral terms versus the usual 5), but I have only verified the Newland terms.
