I am trying to apply this regex to check for a valid UK driving licence number and it doesn't work is my syntax wrong?

Code: Select all

^[A-Z9]{5}[0-9]([05][1-9]|[16][0-2])(0[1-9]|[12][0-9]|3[01])[0-9][A-Z9][0-9][A-Z0-9]([0-9]{2}?)$

You may need to enclose in '/'

Code: Select all

/^[A-Z9]{5}[0-9]([05][1-9]|[16][0-2])(0[1-9]|[12][0-9]|3[01])[0-9][A-Z9][0-9][A-Z0-9]([0-9]{2}?)$/
