TransUnion vs Equifax - The three major differences between TransUnion vs Equifax are as follows: 

1. Information or Data - Due to variations in how lenders report credit activity—such as credit card usage, auto loan payments, and student loan status—credit bureaus might not always have the same data. Due to the possibility of the information being submitted to several credit agencies, this may lead to differing ratings.
2. Updating time - Since credit bureaus update their databases on a regular basis, credit ratings obtained in April from another may differ from those obtained in August. Every 30 to 45 days, creditors submit current information on payments, debt, and new applications; however, they do not transmit it to all agencies at once, resulting in ratings that fluctuate daily. 
3. Credit scoring models - Because different credit-scoring models assess the criteria differently, they may provide different outcomes. For instance, you would receive greater benefits under TransUnion's model than under FICO's if you have a lengthy credit history and pay your payments on time. However, if your credit usage ratio is good, the FICO model will probably offer you a better score than TransUnion, everything else equal.
