USAC will perform an ad-hoc system maintenance on Thursday, April 23, from 9 p.m. to 10 p.m. ET.
The production environments of the following systems are impacted, and users will not be able to perform transactions:
• National Verifier Portal
• National Verifier Carrier API
National Lifeline Accountability Database (NLAD) functions that require the National Verifier will also be affected (e.g., enroll or transfer transactions).
We apologize for any inconvenience this may cause.
