Vacant (mail status)
By Justin Winter · Updated August 28, 2026
A USPS designation for an address the carrier believes is unoccupied, which affects whether mail is delivered, forwarded, or returned.
Carriers flag a stop as vacant when no one appears to be receiving mail there, and USPS systems use that status when deciding whether to hold, forward, or return incoming mail rather than deliver it. It is a delivery-route observation, not a formal legal determination that a property is unoccupied.
It matters for anyone mailing to an address that has recently turned over — a letter to a just-vacated unit can bounce as vacant well before a new resident's change-of-address record exists.
