I've previously mentioned I have been having continuous problems with DPD. Now I have pinpointed something and I just wonder if anyone on here knows how it works.

The last two missing deliveries and some previous ones I have watched on the online GPS tracker. Anyone who has used this will know it shows two "flags", one showing where the van currently is and the other showing your location. Now for the last two at least the flag showing "my property" has been about two miles away in a different postcode area. So the parcel isn't simply being put through the wrong letterbox but the van is going to the wrong area to start with.

I should point out the parcels have all been 100% correctly addressed in case any one wonders about that.

So it seems to me the underlying issue is the van not coming to the right area to start with meaning there is no chance of me getting my delivery.

Does anyone know how DPD set up a delivery and how the delivery post code gets on to their system? I don't imagine someone sits there manually typing them all in. This is happening to me regardless of who the sender is so its not one supplier or anything. Last week I placed an order with Amazon for 3 items. Amazon sent them out with three different couriers. Royal Mail, Hermes and DPD. Only the DPD one went missing yet again. How does the post code get put on to their delivery route.

I am trying to liaise with DPD over this but just curious in case anyone knows how the system works as at the moment this will keep happening. Is it possible their system for whatever reason isn't recognising my postcode and defaults to the nearest one it can identify?

Has your postcode ever been changed? Wondering whether DPD's database is different from the other companies'.

No our postcode has always been the same. DPD in the past have delivered many times without issue. Just the last 12-18 months have been a nightmare. I have put our post code in to all sorts of online maps who all find us with no problem.

That's why I'm curious how DDPs system actually works. It's obviously the post code because the rest of the address bears no resemblance to where they have been going. They must use sat nav when delivering but how does the information get on to it in the first place? We either get the parcel supposedly "delivered" but not to us or returned to the supplier as not being able to find us which they won't of course.

You would think they would all use the same postcode database that the Royal Mail provide.

Have you tried checking what postcode the delivery location shown on the DPD tracking site is? If it is very similar then they might have transposed it into their systems incorrectly, eg changing a 5 into a 6 or something similar.

Clicking on Google maps often shows the postcode for a particular bit of street if you zoom in enough.

Yes I have done that. Its one letter different at the end. We end 3PT and they have 3PR. I don't know how their systems work or how the post code data gets on to their software. This has been my suspicion for some time that there is an underlying issue. Speaking to the driver etc isn't going to help if they don't get to the root cause as he's only gone where it's told him to.

Would be pretty hard even with a hand written label to mistake a T for an R I would think.

Even so you would hope that they check the street and house number before fixing the delivery location into their system. After all even if the postcode was 100% right it could cover dozens of properties anyway.

Well the last one went to xxxxxx Farm instead of x xxxxxxx Cottages. I believe at least a couple others ended up in that direction too. I only know because the person who got the latest one tracked us down. That's when I put two and two together and realised it was the post code being used causing the problem.

If you use this page, it will tell you where your local delivery depot is located. Could you go there and find someone who you could explain the problem to and hopefully get it sorted out?

Yep, I'm in contact with them at the moment and waiting for a response. I was just hoping someone on here may have worked for them or knew their system and could explain it. I was originally going back to the various suppliers but getting no real joy as they don't seem to grasp the problem. Mind you its not particularly local, about 60 miles away!

An easy mistake to make, since R and T are next to each other on a keyboard. I often get mixed up with the next street - I get their stuff, they get mine - simply because my postcode is EHnn nQR and theirs is nQT

But you would hope that if they are hand typing the post code into their system that they are also looking at what they type and check it's correct. Then again maybe they can't be bothered....
