*never received tnt tracking, you just need to use PEX number to track on tnt site.
Now that is really useful for people.
All I received from HMPO was a text and email with similar wording:
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.
