Hello,
Thank you for posting in Q&A forum.
Looking for your Microsoft Certification Identification Number (MCID)? That’s an easy one: log into your Learn profile and choose “Settings” from the avatar photo drop-down menu.
Scroll down to the Connected certification profile section and find your MCID in the second column opposite your account information.
Note
If you have not yet connected your certification profile to your Learn profile, this section won’t be visible. Please visit Connect a certification profile to Learn to complete this step.
I hope the information above is helpful.
Best regards
Zunhui
