Hi All just read an interesting post on the Liverpool office.
It turns out you don’t need a tracking ref from TNT you can use your application ref.
I didn’t bother clicking on the Tracking link Sent by HMPO due to the wording in the email and text as it says TNT will provide tracking details.
Your new passport has been printed, and will be transferred to our delivery supplier in the next few days. In most cases it will be delivered by TNT delivery services. When it’s ready for delivery, they will contact you with a tracking reference.
