While a banner cannot be equipped in the head slot in Survival mode, equipping it using commands causes it to appear on top of the player. This is how pillager captains wear banners.
In Java Edition, a banner can be given a custom name that remains as the banner is placed and retrieved. The player can use an anvil to rename the banner item, or may change the CustomName tag using the /data command on the banner block.
In Java Edition, right-clicking on a banner with a map selected places a marker of the banner’s position on that map, and right-clicking again removes it. The marker has the same color as the banner’s base without decorations. The marker is removed if the banner is destroyed unless the map is locked using a cartography table. If the banner is renamed, the name appears below the marker.
Other blocks (including other banners) can be placed on any edge of a banner’s hitbox, which is only one block high despite the banner appearing as two blocks tall. This makes it possible to overlap another solid block on the top half of a banner.
In Bedrock Edition, banner blocks use the following data values:
Banners can be crafted from wool and a stick.
Banners are tall decorative blocks, featuring a field that is highly customizable using dyes.
Banners can be broken with or without a tool, but an axe is fastest.
Water can be placed below wall banners
