[PLUG] Emacs regex search-replace wild cards

I have 4-digit numbers beginning with 20 that I want to replace with a
string in a file edited with emacs. Specifying the regex search using either 
20?? or 20[0-9][0-9] fails to replace anything. My web search found nothing
relevant.

What have I missed?
