You can reactivate an AdSense account that you've closed and start using it again.
To reactivate your account:
- Sign in to your AdSense account.
- Click Reactivate account.
- Resubmit your site for approval.
We then check your site to determine if it’s ready to show ads and meets the AdSense Program policies. This usually takes a few days, but in some cases it can take 2-4 weeks. We'll let you know when we've completed the checks and your site is ready to show ads again.
Note: If your account is inactive for 10 years, you won't be able to access or reactivate your account.
