Automatic card numbering gives every card on a board a short, permanent identifier called a Short ID, made up of a board prefix plus an auto-incrementing number (for example, PROJ-123). Once a card has a Short ID, that ID never changes. You can copy it, search for it, and use it to reference the card in conversations, emails, commits, and external tools.
Without a Short ID, referencing a card means pasting a long URL or copying the title. Titles change. URLs are unwieldy. Short IDs solve that with a stable handle for every card.
Who it's for
Automatic card numbering is built for larger teams and for teams that work in a ticketing workflow. If your team is used to referencing tickets by ID in commits, pull requests, support conversations, or external tools, this brings the same pattern to Placker.
Enable Automatic card numbering on a board
Open Board settings.
Go to the Overview tab and scroll to Automatic card numbering.
Choose Enabled, or choose Inherit from workspace setting if you want the workspace default to control it.
Set a Board prefix. Use 2 to 7 characters, letters and numbers only. The prefix must be unique within your workspace. Leave it empty and Placker will generate one for you.
Click Save changes. New cards on the board will receive a Short ID automatically.
Enable Automatic card numbering across the workspace
If you want all boards in your workspace to use Short IDs by default, you can turn it on at the workspace level. Individual boards can still override the workspace setting.
Open Workspace settings.
Find Automatic card numbering and choose Enabled.
Boards that are set to Inherit from workspace setting will pick up this default. Boards that have their own explicit Enabled or Disabled setting will keep using that.
Where you'll see the Short ID on a card
Once a board has Automatic card numbering enabled, every new card gets a Short ID. You can find it in two places:
Card front: shown near the title in board view.
Card back: shown in the right sidebar as Short id. Click to copy.
Things to know
Short IDs are immutable. Once assigned, a card's Short ID never changes. Moving the card, renaming it, or editing it does not affect the ID. External references stay valid.
Changing the prefix only affects new cards. If you update the board prefix later, existing cards keep their original Short IDs. Only cards created after the change use the new prefix.
Mirrored cards get their own Short ID. Short IDs are board-unique. A card mirrored to a different board gets a separate Short ID on that board, since the prefix and counter belong to the destination board.
Prefix rules. 2 to 7 characters, letters and numbers only, unique within the workspace. Leave it blank and Placker generates one automatically.
