Step 1:
As always, you need to be an admin of both pages and they should have the same mailing address and similar page names, which will indicate to Facebook that these pages represent the same business. If the page names, addresses or categories are not similar, edit the page you don’t want to keep. Note: Facebook limits how many times you can change the name of a business page.
Step 2:
Click on the admin settings tab of either of the two pages you want to merge. Under the “general” features, there will be a menu item at the bottom called “Merge Pages.” Expand it and click on the “Merge duplicate Pages” link. You can also try this link.
Step 3:
When you click the link, a pop-up box will appear asking for your Facebook password.
Step 4:
After entering your password, you will be directed to a new page where you will be asked to choose the two pages you want to merge together. The drop down menu will list all the business pages you manage so be sure to choose the page you want to keep in the top box and choose the page you want to merge in the second box, as it will be permanently removed from Facebook and you won’t be able to unmerge it. Note: you will lose all timeline content from the page you want merged. Click ‘Merge Pages’ and a pop up window will appear if it was successful.
Step 5:
In most cases, the above steps complete the merging process and the duplicate page will no longer exist, while the main page will now include the likes and check-ins from the duplicate page. This process tends to be quick, and you will immediately no longer be able to access the page you merged. (It can, however, take a few hours for the likes/check-ins to appear on your remaining page).
However, if you are unsuccessful in merging the pages, a pop-up window will notify you, and you can click on ‘Contact Support’. This will take you to a page in Facebook’s Help Center, where you can try the merging process another way. This should work as well, though it tends to take longer.
On the help page, check the box next to “I have read and understand the above information,” and a drop-down menu will appear that contains a list of all of the pages you manage. Select the page you want to keep.
Scroll down and check the box next to “I understand that the Pages I merge must be about the same thing” to reveal the second drop-down menu, and then select the page (or pages) you want to merge. Once you submit the request, you’ll get an email from Facebook confirming that the process has begun. Allow one week for Facebook to merge the pages. You will receive an email notification when the process is complete.
Facebook recently added a ‘Page Support’ tab. This can be found under your main page’s admin Settings. You’ll see a history of your support requests (including your merge requests), and the status of those requests.
