MLB authentication # question

I wouldn't worry too much about that. MLB and NFL Auctions both screw up their holo verification databases from time to time. I have a Sammy Sosa autographed jersey that doesn't register in the database either, and it has a Mounted Memories Hologram on it as well. I have bought items on Ebay from NFL Auctions that when I go to look them up have an entirely different item listed/pictured. As long as there's a legit MLB Hologram on it, I wouldn't sweat it.`

Any thoughts on it's being prefixed "MA" and no MA being listed on their site as a prefix?

I wouldn't worry too much. Are you buying this off of Ebay ? As long as it's a legitimate MLB hologram, You should be good. These guys(Especially NFL Auctions) don't put a whole lot of care into their data entry at times. My Sosa Jersey has the same issue. I couldn't find the prefix either.
