You have multiple Business Instagram accounts.
You are wondering if you can link more than one Business Instagram account to a Facebook Page.
The Answer: No, unfortunately 😕
Facebook only allows one Business Instagram account can be linked to one Facebook Page.
And visa versa: Only one Facebook Page can be linked to one Business Instagram account.
If you try, you will find that there is no option to add a second Instagram account to a Facebook Page – only the option to disconnect the currently connected Instagram account:
You also cannot link multiple Facebook Pages with the same Business Instagram account.
If you try, you will get this error message:
You will only be able to connect it if you remove the previously linked Facebook Page.
If you try linking the Business Instagram account and Facebook Page from the Instagram app, it will only allow you to select one Facebook Page to connect to your Instagram account:
So what’s the solution?
The solution is to create another Facebook Page, then link that newly created Facebook Page with your second Instagram account.
Once done, you will have 2 Facebook Pages, each with a Business Instagram account connected to it.
