The second and third letters may also contain [WZ]

"^([ABCEGHJKLMNPRSTVXY]\d[ABCEGHJKLMNPRSTVWXYZ])" .
"\ {0,1}(\d[ABCEGHJKLMNPRSTVWXYZ]\d)$"

seem to work as it is.


^(?=.{3} ?.{3})(?!.{0,}[DFIOQU]|[WZ])(?:[A-Z] ?\d){3}$

  • (?=.{3} ?.{3}) Positive lookahead

    ◦  string matches [3 charters] [optional space] [3 charters]

      ▪  charters are restricted in the rest of the expression

      ▪  remove the question mark to make the space required

  • (?!.{0,}[DFIOQU]|[WZ]) Negative lookahead

    ◦  .{0,}[DFIOQU] string may not contain ‘DFIOQU’

    ◦  [WZ] string may not start with ‘W’ or ‘Z’  

  • (?:[A-Z] ?\d){3} Basic pattern repeat 3 times

    ◦ [any letter A-Z] [optional space] [any digit 0-9]

      ▪  spaces are restricted (index 3 or none) in the Positive lookahead 

      ▪  letters are restricted in the Negative lookahead
