About Customer File audiences
Last updated, July 2024

You can create a Customer File custom audience by uploading a list of leads or customers. When you upload a .csv or .txt file to your TikTok Ads Manager, TikTok will search for users on the platform that match the provided IDs. After matching, a custom audience will be created, and your uploaded file will be promptly deleted.


The audience manager page in TikTok Ads Manager displays the size of total matched users. This helps you get a better understanding of the presence of your audiences on TikTok. Only opted-in people can be reached with a TikTok campaign.

  • Customer file audiences can be used in campaigns to promote products or services to your existing list of leads or customers.

  • You could also optimize ad spend by excluding recent conversions.

  • You could also create a lookalike of this audience for prospecting campaigns to find new customers.


You can review the example file to help create a customer file to upload.
