Request to merge multiple Microsoft Learn certification IDs

Hey dear,

First thing to try, the self-service merge.

Since you have three IDs (not two), you'd need to do this in two steps — merge the second into the first, then merge the third into the combined profile.

If self-service doesn't work (which happens when accounts have conflicting types), you'll need to go through the official certification support channel, this is the right place for exactly your situation:

One more tip: once your profiles are merged and PL-900 shows up correctly, add a personal Microsoft account to your primary profile as a backup login. That way you won't get split across multiple IDs again if you ever change work/school emails.

Good luck
