Claude Verification Code Not Working – How to Fix
Make sure you’re using the newest code, enter it promptly, and avoid copying extra spaces. If it still fails, request a fresh code and retry in incognito.
Step-by-Step Fix
1. Use the Most Recent Code
If you requested multiple codes, older ones may be invalid.
2. Enter the Code Quickly
Many codes expire quickly. Try within 1–2 minutes.
3. Type Manually (Avoid Extra Spaces)
Copy/paste can introduce spaces or formatting characters.
4. Retry in Incognito / Private Mode
This avoids stale cookies and cached sessions.
5. Clear Cookies and Restart the Flow
- clear site data
- restart browser
- request a new code
6. Switch Browser or Device
If it works elsewhere, the issue is local to that browser profile.
7. Contact Support
Include the exact error message and the time you tried verifying.
Common Mistakes to Avoid
- Troubleshooting the wrong account or workspace.
- Retrying without checking whether there is an active outage or plan restriction.
- Clearing local state only after multiple failed attempts instead of testing in a clean browser first.
What to Gather Before Contacting Support
- Capture the exact error message and the time it happened.
- Record whether the issue happens on another browser, device, or network.
- Note which account, workspace, or subscription plan is affected.
