A device for providing a positive indication that the door of a rural-type mailbox has been opened includes an elongate indicator strip with a first end and a second end, formed of a flexible, shape-retentive material with a spring bias toward a curved rest configuration. The indicator strip is connected at its first end to a mailbox such that the curved strip extends outward from the mailbox when in rest configuration, and may be flattened against the mailbox with the second end of the indicator confined between the sidewall of the mailbox and the lip of the closure door to hold the indicator against the mailbox in a cocked position. When the mailbox door is opened the second end of the indicator is released to assume its outwardly extending rest position and provide a visual indication that the mailbox has been opened.
