This is a recurring question we see from users across the Atlassian ecosphere. For new Jira users especially, it can be quite confusing. A quick search on the web will return lots of articles and videos and graphics of all sorts. In this article, I will throw my two cents in, which hopefully you will find helpful.
Jira Components and Labels are two essential features used to organize and categorize issues in Jira. While they serve similar purposes, they differ in their scope, control, and usage.
Labels are essentially just an open text field. Meaning that there is really no control on the values that people type in them. And they are case sensitive and do not allow spaces!
So, if you search on the Label field the values of Cat, cats, cat, catt, Cats, catz, etc. would all be different values, and some issues would not show up depending on the typos or case used. This means you could easily end up with poor or unintended search results.
Components are created at the project level and appear in a drop down for users to select from. Much better for filters, queries, consistency, sanity, etc.
Our friends from the AI world have a good synopsis here:
Components
- Scope: Project-specific, defined and controlled by project administrators
- Control: Admin-controlled, with a fixed set of values
- Usage: Group related issues together, identify areas of a project affected by an issue, and filter issues by component
- Example: In a software development project, components might represent different modules or features (e.g., “Backend API” or “Frontend UI”, iOS or Android)
Labels
- Scope: Project-independent, can be used across multiple projects and your entire Jira organization
- Control: Anyone can add or remove labels, with no nomenclature control
- Usage: Categorize issues based on their nature or characteristics, quickly tag issues for easy reference, and filter issues by label
- Example: In a business project, labels might represent months or groups (e.g., “December”, “Legal”, or “Marketing”)
Key differences:
- Control: Components are admin-controlled, while labels are community-owned and lack nomenclature control.
- Scope: Components are project-specific, while labels are project-independent.
- Usage: Components are better suited for structured grouping and filtering, while labels are more flexible and adaptable for quick tagging and categorization.
When to use each:
- Use Components when:
- You need a structured grouping system with controlled values.
- You want to identify areas of a project affected by an issue.
- You require robust filtering and reporting capabilities.
- Use Labels when:
- You need a quick and easy way to categorize issues.
- You want to allow team members to add their own tags.
- You require flexible and adaptable categorization.
Having said all of that, I think you might find this previous response to a Community post by Nic Brough to be quite helpful:

The bottom line is that you should use what works best for you and your organization. But be consistent and aware of the pitfalls and strengths of each.
For me, I avoid Labels like the plague (or Team-managed projects, which I also consider to be very plague-like). The frustration that comes with unavoidable typos and case differences WILL happen, and I just don't need that in my life. :-)
