You cannot claim a profile that has already been claimed but you can ask the current owner to add you as an admin.
If one of your Facebook profile is claimed by someone else we recommend trying to contact this person and sharing the access to this profile. The owner can add you as an admin by following these steps:
1. Go to your Page and click Page Settings in the bottom left.
2. Click Page Roles in the left column.
3.Type a name or email in the box and select the person from the list that appears.
4. Click Editor to select a role from the dropdown menu. We recommend adding as admin to avoid any issues with updating the data.
5. Click Add and enter your password to confirm.
The person who you just invited should receive an invitation to manage the page. Please connect the page with Localistico by adding the credentials. Please refer the article "How to add Facebook credentials" for further information.
If you don't know who is the owner of the profile and you would like to claim the profile, please contact to Facebook support team here.
