Credit Report (Agency iD Reports too)

Hi.

I’m wondering if someone can help me, I took out a contract in Q2 of 2023, and noticed that iD is reporting to experian and equifax. I know some companies don’t report to one of the big three agencies. 

Does iD Mobile report to transunion as my report their is blank of any contract. (I don’t know if it will help, but both experian and equifax has reported 8 payments).

Edit: I should have noted that I use CheckmyFile and Transunion directly to check this, both are blank.
