An extra piece attached to a stamp containing text and/or graphics. Tabs may be joined to the stamp with or without perforations. If the tab is joined without perforations it is known as an integrated tab. If an integrated tab is removed, it creates an imperforate collectable stamp.

A stamp with a tab that has a customer’s design printed on the tab, is known as a Personalised Stamp or P-stamp. (See Personalised Stamp.) If the tab contains a photo it is often referred to as a “photo tab”. Occasionally Australia Post issues tabs with a ‘generic’ photo. These stamps and tabs are not P-stamps. They are usually issued in Special Event Sheets or Special Occasion Prestige Booklets.
