Around 8 million deliveries per year
That’s just the letters….
Loads of things that could go wrong,
postcode code have been entered into the system incorrectly,
Address can be misread
could have got stuck in a sorting bag (this happens a fair bit) and delivered through to the wrong sorting office,
tracking label could detach from parcel / envelope and reattach to another in the bag going somewhere else. – this happens more often with waxed paper/card boxed or packages/letters with eco tape.
Although you’d expect the postman to be able to read that it’s in the wrong postal town before delivery – however RM have lost large swathes of experienced postal workers in the last 18months (remember those strikes?).
For comparison evri have delivered a parcel to the wrong business address, 6miles away from me, four times in a row over the last week – each time the driver has turned up at my house (next to my business) an hour or so later to deliver a domestic package and ive told him he’s delivered to the wrong address, he shrugs and says claim from the company 🤷♂️ – which I would do but he delivered to the wrong address again!!!
