I understand completely I too have one. I was just letting you know its not a license, its a certification. There is a difference. You may have been issued a "license number" but it doesn't mean you have a "license" you have a Certification.
Licenses are mandated through regulatory or government agencies and define the title and scope of practice. Having a certification is typically offered by an industry to uphold certain standards. A certification is the recognition of an individual who has demonstrated through a standardized assessment that they meet defined qualifications within a profession.
I wasn't trying to be rude, I was just letting everyone know there is a difference. Its good information to know for Job interviews etc.
