Hi Backlog users,
Some of you will have similar questions as I when I first started using Backlog:
What is a Backlog Space?
The Backlog Space refers to the organization’s online space where all their projects, project information, files, and members are stored.
What is Space ID?
Well, Space ID is related to the Backlog Space, it’s a subdomain address where the space is located. When a Backlog plan is started, an online space in Backlog is created and the Space owner (i.e. the person who started the plan) is asked to give a Space ID for it. The ID is used for the subdomain address at Backlog, like
This way, members can access the Backlog Space using the URL. For example, if your Space ID is CoolSpace, then your Backlog Space is at
Note: Once a Space ID is assigned, it cannot be changed by the user. Please consider this when you create a Space ID.
What to do when I forget my Space ID?
There are several ways to retrieve your Space ID.
- If you are the Space Owner, when you registered your Backlog Space, you would be emailed the Space ID. So simply retrieve that email to find your Space ID. Something like:
- If you have been invited to join a Backlog Space, you can find the Space ID in the invitation email. Something like:
If you are unable to find the emails, or they have been deleted, try searching your browser history with the term ‘Backlog’. This might bring up some helpful results, especially if you have visited your Backlog Space previously.
Try contacting the Space Owner, Administrator or Project Administrator that invited you. But if it so happens that you’re the Space Owner, you’ve forgotten your Space ID and you can’t log in, you can contact our Backlog support team for help at https://backlog.com/contact/
Tip: Store your Backlog Space URL as a bookmark in your browser, so you can access it any time. That’s what I do!
Is Space ID the same as Organization name? No.
Space ID and Organization name are not necessarily the same words. They can be different names.
If you’re the Space Owner or Admin, you can change your Organization name (under Organization Settings), but this won’t affect or change the Space ID. The Space ID is fixed and not changeable once it is created.
What if I really want to change the Space ID?
The Space ID can only be changed if the new ID is not already taken, but this move takes time and also requires an additional fee. If you really have to make a change, please contact our Support team and we’ll check whether it’s available.
I hope this answers your queries about Backlog Space ID.
