text: No it's needed for any perscription.  Also for Class II narcotics some states require registering with the state, and that also creates a state number.  ie In TX a perscription for demeraol (sp) requires a triplicate form, and in order to do these the doctor must register with the state.  \n\nNow this doesn't mean you can "demand" a DEA number from a doctor for any reason, but if you're getting a perscription they'll have to give it out.
