A valid email is required to claim any business page. If your business page has a email but the Claim this business button and the Business Owner? Claim this business link don’t appear, then the business page may have already been claimed by one of your colleagues.
If you don’t know who claimed this page you’ll need to pursue the matter internally to find out. The original account holder can also contact us directly to request access on your behalf.
If you’ve done all of the above and are still unable to claim your business page, please contact our Support team.
