I'd assume most countries don't bother remapping when it comes to Street numbers ? France has a suffix system, so you if a buildings are added between 24 and 2

I'd assume most countries don't bother remapping when it comes to Street numbers ? France has a suffix system, so you if a buildings are added between 24 and 25 you'll get 24 bis, 24 ter etc. Japan doesn't care about the ordering in the first place, so a block added between 24 and 25 and 26 will be 32 without any issue.
