I had one residence, two addresses.

one recognised at council level, the other recognised at State/Federal level.

exactly the same house...as some services recognised the one street but not the other, I had mail delivered to both. The posties knew of this ridiculous situation and were great at delivering the mail. If the regular posties were on holiday, sometimes mail would be returned. Both addresses were therefore accurate, but either might not be acceptable to use, depending on whether it was considered correct by the sender/online address database.

An unusual thing, I know, but just throwing it into the mix 🙂
