Dick,
I,Q and Z cannot be used as part of the area code i.e the first two letters of the registration but Z is allowed in the last three letters of the registration referred to as the random letters
I think Z did occur in Irish plates. ZA was Dublin, ZR Wexford and the other way round AZ was Belfast, RZ was Antrim. Got that from a booklet I have, written I believe by some one with Asperger's Syndrome which is appropriate as there is also a thread on Autism Awareness Week.Dick,
