Before you begin
Prepare your customer list in advance

To make a Custom Audience from a customer list, you provide us with information about your existing customers and we match this information with Facebook profiles. The information on a customer list is known as an “identifier” (such as email, phone number, address) and we use it to help you find the audiences that you want your ads to reach.

Your customer list can either be a CSV or TXT file that includes these identifiers. To get the best match rates, use as many identifiers as possible while following our formatting guidelines. You can hover over the identifiers to display the formatting rules and the correct column header. For example, first name would appear as fn as a column header in your list.

Next steps

  1. Add your customer list: You can create your Custom Audience in Ads Manager. Once in your account, go directly to Audiences, then go to Create audience > Custom Audience > Customer list
  2. Prepare your customer list: Select the identifiers to include, then add the customer list that you want to use for your new Custom Audience and give it a name.
  3. Review your customer list: Confirm that you mapped your identifiers correctly or check to see that all errors are resolved. You’ll get one of the following notifications:

The green tick symbol means that your identifiers were mapped correctly and are ready to be hashed, then used for the matching process.

The yellow exclamation symbol  means either that you chose not to include certain identifiers or that some identifiers need to be manually updated. You have higher chances of getting a better match rate to build your audience if you make the corrections before uploading your file.

  1. Upload your customer list: Once your list has been added and is ready for use, select Upload and Create.

When we’ve finished hashing your customer list information, we’ll let you know that your audience is ready to use. Once ready, you can immediately create an ad to reach your new Custom Audience, or create a Lookalike Audience to find new people who share similar behaviours and interests with your existing customers.

Before you add your list at 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.
