How to tags individual house?

I’m living in the rural countryside, the delivery is limited and it’s hard for local people here. Because of the low-income province, we still don’t have our own house number and have to receive goods at the post office. I would like to tag my own location in order to trade goods to the downtown, it saves more time. How can I do that?

Thank you so much for your help.

addr:full= can be used for the landmark-based directions used by locals. If there’s no special addressing, you can’t tag it, but can simply share your coordinates.

Or use your pluscode
