# Id Batch ### What is audience-sharing? An audience share is: * a list of IP addresses or * the list of IDFAs / GAIDs (unique device identifiers) of individuals who have been exposed to the ad during its broadcast. ### When to provide an audience-sharing file? At least 100,000 IP addresses or IDFA / GAID are required, to launch a Brand lift. You have up to the Brand lift collection start date, to share the complete list of IP, IDFA or GAID addresses, so that we can use the exposure data for the responses collection. ### How to upload an audience-sharing file? To provide a file for audience sharing, simply import the CSV file on Happydemics, by clicking on "Upload" as shown below. Only one file can be uploaded with the minimum audience required. You can download an example template with the required audience file format. Only files with the same format as the template and the minimum ID required will be accepted.

### How are audience-sharing files securely stored? Once imported, the file is stored in a secure environment on our servers. It will be automatically deleted at the end of the collection process. If you need to edit this file, please contact us. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
