License Verification Details

✕Have a licensing question? Contact your licensing board or check their website. Help desk representatives are not trained to answer licensing questions.

Technical Support - Help desk representatives are available to answer login or registration questions by calling (855) 405-5514 weekdays from 8:00 am to 5:00 pm EST.

Callers may experience extended wait times due to the high number of calls. If you’re unable to wait for a representative, you can leave a call back number.
If you’re experiencing technical issues with the eLicense website, make sure you are using Google Chrome or Mozilla Firefox as your browser on a desktop or laptop device.

NCSBN maintenance on Wednesday, April 8, 9:00 AM–1:00 PM CT may temporarily impact Nursing Board services, including SFTP file uploads and application processing.
