License Verification System (LVS)

Summary

The License Verification System (LVS) and License Verification Portal (LVP) enable direct verification of radioactive materials licenses.

The NRC provides two electronic license verification tools as part of its Integrated Source Management Portfolio (ISMP): the License Verification System (LVS) and the License Verification Portal (LVP). Both provide access to official radioactive materials licensing information maintained in the NRC's Web-Based Licensing (WBL) system, allowing users to verify licenses directly through the NRC.

License Verification System (LVS)

Deployed in May 2013, LVS is an integrated service designed to provide access to Category 1 and 2 license information maintained by the U.S. Nuclear Regulatory Commission (NRC) and Agreement States. The system helps licensees meet the license verification requirements of 10 CFR 37.71, or the Agreement State equivalent, by allowing them to confirm that recipients are authorized to receive the type and quantity of radioactive material being transferred.

LVS retrieves licensing information from WBL and, as applicable, the National Source Tracking System (NSTS). Access to LVS requires users to be credentialed. 

License Verification Portal (LVP)

The NRC has developed the LVP to provide a simple and convenient way to access official copies of NRC radioactive materials licenses that are not subject to the Category 1 and 2 license verification requirements of 10 CFR 37.71.  

Newly generated NRC licenses supported by the portal automatically include a unique QR code and embedded hyperlink. By scanning the QR code or selecting the hyperlink, users can access the portal and retrieve an official copy of the current, active license directly from WBL. Unlike LVS, the LVP does not require user credentials.

LVP Frequently Asked Questions

  1. Do I need an NRC account or special software to use the LVP?

    No. The LVP does not require user credentials or specialized software. Users only need an internet-connected device capable of scanning the QR code or accessing the embedded hyperlink.

  2. What if a license does not have a QR code or hyperlink?

    NRC licenses issued before implementation of the LVP may not contain a QR code or embedded hyperlink. These features will automatically be included the next time an eligible license is amended or renewed. The absence of a QR code or hyperlink does not affect the validity of the license. Licensees may continue to use the applicable verification methods outlined in 10 CFR 30.41(d).

  3. What should I do if I cannot retrieve a license through the LVP?

    If the LVP is unable to retrieve a license, confirm that the required license information was entered correctly. If the problem continues, contact the LVS Help Desk for assistance.
