The crux of the issue is that I don't have a street number, but I do have a house name and number. My address is something like: 2 My House Name My Street Name Postal Code
That is what it says on the Royal Mail's address checker, the title deed and every other map, except google. The edit I submitted via google maps still says pending a couple of months later and the communities forum doesn't accept that I don't have a street number and so can't/won't help.
The effects of this is that nobody can find my house on google maps which I'm learning that quite a few delivery services use.
Anybody got any hints or suggestions?
I had a similar problem trying to get my address added to Google Maps and other platforms! I live in the US, and the post office changed my address (new number and street name) when a new road was cut in near my house. It was incredibly frustrating! I tried on and off for weeks submitting reports, which were all closed or ignored. I figured out that if you create a business, Google will let you put in the address of the business and drop a pin on the map where the business is. They do not verify if the street address was previously in their database. So I created a fake business on Google and gave it my home address, and dropped a pin on my house. It showed up on the map within hours. Kind of hacky, but problem solved. Good luck!
I suggest you find a Local Guide with a high level that can make those modifications for you, Google is likely to accept theirs.
