Also, do not fully rely on Google Maps knowing house numbers. Looks like in some areas (in UK for example) Google used some sort of OCR to find house numbers. There are houses and Wales with random house numbers that only have a house name; Numbering ends a few houses into dead-end alley where the Street View car didn't come; Or totally wrong numbers where house number sings are hard to read.
Australia went to mandatory house numbers in, I think, the 60s but my grandmother refused and gave out only her house name until she passed away in the 21st century.
Does your location have a Place ID? Google originated Place IDs for exactly this type of use case, so that people could find places like yours without an address.
