Answer 1

Try this

^[A-Z]{2}\s[0-9]{2}\s[A-Z]{2}\s[0-9]{4}$

^ means start of string
[A-Z]{2} means 2 characters in the range of A through Z
\s means white space
[0-9]{2} means 2 characters in the range of 0 through 9
\s means white space
[A-Z]{2} means 2 characters in the range of A through Z
\s means white space
[0-9]{4} means 4 characters in the range of 0 through 9
$ means end of string

Based on what you said in your question this should be a very broad check against proper format, but I have a feeling that there are more specific regulations on how the license plates are numbered. Let me know if there are additional constraints for the regex.
