Removal by one CRA does not necessarily require removal by other CRAs. It depends upon the facts of what was disputed, and whether any removal by a CRA was as a result of a direct finding by that CRA that the accuracy of the specific information could not be verified.
When a furnisher receives a dispute filed with a given CRA, they are required to respond back to the CRA with either verification of the accuracy as reported, correction of any agreed inaccuracy, or deletion if they cannot verify.
The CRA then makes the final determination. If they receive either verification or correction from the furnisher, they will almost never delete, and their Notice of Resuts of Reinvestigation will inform the consumer of the outcome. If the CRA does not receive either verification of accuracy as reported or correction of an inaccuracy, they are requried to delete if they cannot verify without input from the furnisher or correct.
A furnisher can choose not to provide verification or correction in response to a given dispute, and thus permit deletion of the disputed information.
Howver, they can also choose to either verify or corrrect with any other CRA, and thus retain the disputed information.
A furnisher will rarely send a positive statement to a CRA that the information cannot be verified. If they do make a determination that information is inaccurate and cannot be corrected or verified, then the FCRA requires that they also provide deletion with all CRAs to which they have also reported the disputed information.
That avoids the need for a dispute with each CRA if the furnisher clearly finds it to be unverifiable.
However, lack of a statement of verification is not the same as a positive admission that information cannot be verified, and thus does not mandate deletion with all CRAs.
Removal by one CRA is rarely basis for requring removal by others.
You normally must obtain a separate finding by each CRA.
