You can actually add more than 1 state/license to each field. For example, let's say you have 2 state licenses you'd like to display on your CE certificate. In your profile under Licensing State/License Number add the following:
Licensing State: "FL/MD"
License Number: "FL_10123/MD_L33745"
You can choose any format you like really, just as long as you get the point across. Most states do not require a licensing state to be present on a CE certificate, but we make the option available to our learners. But some learners may want to display that information especially in cases where the course is mandated by a particular state - for example, a biannual course on practitioner substance abuse/mental health awareness.
