Couriers can't find my flat

[bonvoyage2]

I've had trouble with getting parcels delivered and one of the drivers said that the sat-nav takes you to the wrong street. I live in a flat, and whilst it's all one building, one of the flats is on its own on Example Street, with the postcode AB12 3CD. My flat is on Other Crescent and has a different postcode to the example street one. But I put in my postcode on Google maps and sure enough it takes you Example Street and says you can walk to my address from there, which is wrong. Both streets are near each other but you can't get to my flat from Example Street (I've included a poorly drawn diagram so you get an idea). Is there a way to get it changed on Google Maps so that when you put my postcode in, it will take people to Other Crescent and not Example Street? Royal Mail and Hermes and others with the same drivers are mostly ok unless our one is absent, but Amazon is a problem. A site I bought from has decided to use Amazon as the courier so I'll have fun and games tomorrow 🙄

I should add that we put delivery instructions but they never follow them

You could try what3words?

Yes there is as we had a postcode that took you to the other side of the field that borders where we used to live. You need to find your local google editor. They can alter the entry for you. These are local volunteers.
Now I’ve no idea how you find yours - I accidentally discovered ours through moaning about the same courier problem when I was bell ringing one Saturday. (Funny old world sometimes) But you could try Facebook and see if anyone pops up?

Another vote for What3Words - a lot of courier companies now accept their locations

Does the housing opposite have a different postcode, use theirs?

@bonvoyage2

here you go. Report the problem this way.

Our post code on some websites comes up as 12 common estate instead of 12 example lane, common estate, we've learnt to check the address carefully after some parcels and post getting lost
