What is a user ID in the context of Braze?

A user ID in the context of Braze serves as a unique identifier that allows the platform to recognize a specific user across multiple devices and applications. This unique identifier is crucial for personalizing the user experience, enabling accurate tracking of user interactions, and ensuring that communications and notifications are effectively tailored to each individual based on their behavior, preferences, and engagement history.

By leveraging a unique user ID, businesses can create a cohesive and personalized user experience, whether a user accesses the application from a smartphone, tablet, or desktop. This ensures that users have a consistent journey and that all interactions are synchronized, which enhances user engagement and retention.

In contrast to other options, such as a numeric code for products, an identifier specifically for app developers, or a shared ID among users, the unique user ID directly pertains to individual users, thereby underscoring its role in achieving personalization and effective data management within the Braze platform.
