What three words address

[pcornish1]

I live in a row of 5 houses all with the same postcode and same number with the exception of 4 of them ranging from A to D the anomaly being the fifth which is mine. As a result we have parcels delivered to the wrong address all the time and as what three words is accurate down to a square metre, I wondered if anyone knew how to add it to my account address?

why don't you just add a name to your house and use that as well as the number?

It may be accurate but I have never heard of Royal Mail adopting it.

At the end of the day it is down to the accuracy of the postal staff on your walk
