I have a regex that I thought was working correctly until now. I need to match on an optional character. It may be there or it may not.
Here are two strings. The top string is matched while the lower is not. The absence of a single letter in the lower string is what is making it fail.
I’d like to get the single letter after the starting 5 digits if it’s there and if not, continue getting the rest of the string. This letter can be A-Z.
If I remove ([A-Z]{1}) +.*? + from the regex, it will match everything I need except the letter but it’s kind of important.

Here is the regex I’m using.
/^([0-9]{5})+.*? ([A-Z]{1}) +.*? +([A-Z]{1})([0-9]{3})([0-9]{3})([A-Z]{3})([A-Z]{3}) +([A-Z])[0-9]{3}([0-9]{4})([0-9]{2})([0-9]{2})/
