Can the JIRA Project and Project Key be numberic

[Deleted user]

We have a customer who wants to create a project name using numerals, for example: project 3.15 or 3_15. Is that even possible? If we were able to do something like that is a numeric project key allowed?

Example: Project 3.15  Key 3.15 or 315.

Then issues would be 3.15-00001, 3.15-00002 etc

Thanks for your input.

There is a regex you can change to allow other definitions of project keys, but using numbers is likely to break something else in Jira. I don't recommend doing that.

Instead create a custom field and store this info there. Or in the project description.

In theory, you can change it to such a scheme, but it will break a surprising things in interesting ways.  I've had to "repair" this several times in the past, just to get through upgrades or make apps work. 

You should stick with project keys that at the very least start with a letter, and then 1-9 alphanumerics.

I would recommend storing that sort of thing in the project description
