Just checked TNT tracking online using Passport Application reference number and finally given delivery date of 6th April! I have been checking regularly ever since passport was printed (30th March). I had no other notification that TNT had scanned it into their system. I checked at 3pm today and was still getting an error, then 4.30pm there it was. I was even a little shocked to see it. I changed the delivery date to tomorrow to be on the safe side.
Timeline:
Appeared on TNT tracking 4.30pm 4th April
Passport printed 11.43am 30th March
Application accepted 3.06pm 25th March
