There may be several reasons why this occurred. Lenders, creditors, and other entities don’t always report to each credit bureau on the same schedule. That means you may get the same alert from each credit bureau, but at different times. In addition, not all lenders, creditors, and entitles report to all three nationwide credit bureaus. Some may report to only one, two, or none at all. As a result, you may not always get an alert from each credit bureau.
