‌The Passport Office has issued a crucial reminder for parents of children turning 16, urging them to take action to avoid potential disruption to any upcoming trips abroad. If their birthday is less than three weeks away, skip the child passport and apply for an adult passport instead. Whilst teenagers can continue using their child passport beyond their 16th birthday until it expires, they must obtain an adult passport when renewing. ‌For those requiring urgent documentation, the UK provides a same-day service, though this necessitates booking an appointment at your local passport office. As of January 29k, 2026, the expected turnaround is bout three weeks once the Passport Office has received all necessary documentation.
