There are three services:
Sorry but we do not issue 18+ cards until you attain that age. If you want a 12/15 or 16/18 card now, that's fine, but you will need to re-apply if you want the 18+ card later. The cards don't "run out" so you can use them for as long as you want.
Our cards do not have an expiry date so you can use it for as long as you wish. Bear in mind that as you get older your looks will change, you may want to renew your card to reflect this especially if you want to use your card for clubs and pubs. If this is the case, just call us and we'll advise on your individual requirements.
