Frequently Asked Questions

SEER has two data products available: SEER Research and SEER Research Plus. The Research Plus Data require user authentication with an eRA Commons or an HHS account. The two options to request access are described below.

For Research Plus and NCCR Data

Obtain access using an eRA Commons account that is associated with an institutional email address (.edu, .gov, .org, or work email address). If you do not yet have an eRA Commons account, contact your institute’s Signing Official or Account Administrator about getting an eRA commons account. Refer to the  FAQs for instructions.

Requestors associated with HHS agencies should login with their PIV Cards to request the data. All other government agencies will need to submit a request through obtaining eRA commons credentials.
