If we can not verify the status of a license, we use the status "Unknown". This simply means we couldn't verify them, not that they are operating illegally.
Some states do not provide accurate information on the status of Licenses. For these states that are still getting started and haven't yet figured out a good way to tell us the status of Licenses, we use the status "Unknown".
Most of these are probably pending licenses, but we don't know for certain what the status is. They could have been denied, or they could even be active. We try to keep this status to a minimum and always try reaching out to the State, or License Holder directly to figure out what's going on.
If you find a License in the "Unknown" status and happen to know it's Active, Pending, or Denied, please let us know and we'll update it!
