How to Format Customer Lists

Before you begin

Before you add your list in the beginning of the audience creation process, you need to make sure the column formatting matches the identifier type that Facebook accepts. This helps Facebook process your hashed columns to find matches later on. You’ll also need to make sure your customer information is entered using the correct format types.

For example, if you had a column header that’s for first names, you would rename the column header to fn so it can be mapped properly.
