How do you change address in passbook?

To change your address in the Passbook app, you'll need to update your address in the associated account or service linked to the Passbook. Typically, this involves logging into your account on the issuer's website or app, navigating to the account settings or profile section, and updating your address there. Once you've made the change, the updated information should automatically reflect in your Passbook. If it doesn’t, you may need to delete and re-add the pass.
