# Use unique IDs for ARIA references
When ARIA attributes point to duplicate IDs, assistive technologies may read the wrong label or description, providing misleading information to the user.
## Quick Reference
- Ensure IDs referenced by ARIA attributes (e.g., aria-labelledby) are unique
- Avoid duplicate IDs that lead to ambiguous accessibility relationships
- Verify that ARIA controls correctly target their intended elements
## Check
Identify elements where an ARIA attribute references an id that appears multiple times in the DOM.
