Mapstone currently treats each primary street address as one unique Address NFT. Individual apartments, condominium units, co-op units, suites, and other unit numbers within the same building do not currently qualify as separate Address NFTs because they share the same underlying street address.
For example, multiple apartments located at the same building address are represented by a single Address NFT for that building’s street address. Adding an apartment or unit number does not create a separately mintable NFT.
Mapstone may add support for individual units in the future, but this capability is not currently available and no launch date has been announced.
