There seem to be a range of services purporting to be tracking deliveries but not always providing the recipient with anything useful.
Firstly there is the one used by my online precription service Pharmacy 2U.
Their tracking numbers are not even accepted by the Royal Snail website absolutely NFU to the recipient
Another I find mainly on Ebay that look like this 37032543200003B521918.
Here the tracking info says there will be no update until we deliver it - how helpful again NFU to the recipient
Then there are proper tracking code two alpha, nine numbers and GB on the end that actuall work and give tracking en route and predicted arrival date which is normally spot on.
I've also notice that many signed for parcels dont need an actual signature but I hear Postie outside with a bleeping terminal presumably GPS tracked scanning the barcode out side my door to prove the parcel was at least very very near to my house at a specific time.
Then of course the odd parcel actuall needs a pawprint. These are precision timed for when I'm still in bed or mid sh1t, shower and shave in the morning.
Oh yes, I have also lodged a formal "my safe place" with Royal Snail but they never use it.
Happy days!
