How long do vendors and advertising identifiers replace iPhone UDIDs?

I know that a UDID is 40 characters long. Apple now prohibits their use and replaces them with vendors and advertising identifiers for the iPhone.

I need to replace them in the database, but I can not find their length. How long are these new identifiers?
