Your Apple Pass Type ID expires every year. It is therefore important to renew your Apple Pass Type ID before they expire. You should receive an email from Apple when your certificate is due to expire but we also recommend putting a annual reminder in your calendar at least 30 days before expiry.
WITHOUT A VALID APPLE PASS TYPE ID YOU WILL NOT BE ABLE TO ISSUE PASSES OR UPDATE YOUR EXISTING PASSES.
