text: how do i file for a new license for nursing in the state of montana for a replacement? i lost my license somewhere in my house and need a replacement you would have to contact the state health department. they should be able to direct you to the national state nurse registry. you can give your information by phone and they will also have you probably send in some documents for proof. look up on the website of your state, then go to department of human services. look up licenses and certifications, it should be there. good luck.......nurses are always needed....
