Identity data FAQ

What is identity data?

Identity data links identifiers that belong to the same device or household, such as a mobile advertising ID and a hashed email. Platforms use it to connect targeting, analytics, and measurement across channels.

What is a hashed email (HEM)?

A hashed email is an email address converted into a fixed string with a one-way hash such as SHA-256. The email itself is not delivered.

What coverage is available?

Identity data covers the United States and is refreshed monthly.

How do I know a pair is current?

Each record carries first-seen and last-seen dates plus a validation status, so you can filter by freshness.
