Trello Card Numbers
Give every card a permanent reference number
A lightweight Chrome extension that adds a sequential, permanent number to each Trello card. Stop pasting long card URLs — just say 'card #42'.
Add to Chrome — FreeFeatures
Automatic Numbering
Every card on your board gets a sequential number automatically — no setup, no manual tagging.
Numbers That Stick
A card's number is permanent. It stays the same as the card moves between lists, gets archived, or reopened.
Zero Configuration
Install and go. Numbers appear on your cards immediately — no menus, accounts, or settings to touch.
Why Trello Card Numbers?
Clear References
Say "check card #17" in a standup or a Slack message instead of hunting for a shareable link.
Works Like Issue Numbers
Bring the same short, stable IDs you get from GitHub issues or Jira tickets to your Trello boards.
Private & Local
Numbers are generated and stored in your browser only. Nothing is sent to a server or written to Trello.
Lightweight
A small, focused extension that does one job well, without slowing down your boards.
About Trello Card Numbers
Trello cards are identified by long, unmemorable URLs, which makes them awkward to reference in conversation, commit messages, or documentation. Trello Card Numbers fixes this by giving every card a short, permanent, sequential number the moment it's created — the same way issue trackers like GitHub or Jira number their tickets. The number is shown right on the card and stays with it for its entire lifetime, so "card #42" always means the same card.
How to Install
Install Trello Card Numbers from the Chrome Web Store. Open any Trello board afterwards and numbers appear on your cards automatically — no configuration needed.
