How to Request Access to SEER Data

The instructions to request access to SEER's two data products are described below. Once access is granted, the data is made available through the SEER*Stat software. Each person who will access the data must submit a separate request and acknowledge the data agreements and limitations.

• For SEER Research Plus and NCCR Data
• For SEER Research Data

For SEER Research Plus and NCCR Data

The SEER Research Plus and NCCR Data require user authentication with an eRA Commons or an HHS account. If you cannot obtain an eRA Commons account, are requesting the data for personal use, or do not need access to the additional Research Plus variables, you can register for the Research Data instead.

Note that access to Research Plus Data may be a prerequisite for access to other data such as SEER Specialized databases, NAACCR's CiNA Research data, the NPCR and SEER U.S. Cancer Statistics data, as well as access to data available through the NCCR Data Platform.

Step 1: Apply for Research Plus and NCCR Data Access

1. Log into the Data Request System
• For HHS accounts, use your PIV card and log into the Data Request System.

  • Make sure the account is associated with an institutional email address (.edu, .gov, .org, or work email address).
  • Once you have an eRA Commons account, link it to a Login.gov account following the instructions in How do I link my eRA Commons account to a Login.gov account? Wait two days for the information to propagate to the SEER system.
