Your TransUnion score is usually lower than your Equifax score because the two bureaus hold different data about you, not because one of them is wrong. Lenders are not required to report to all three, so an account, a balance, or a late payment can appear at one bureau and not another. On top of that, the app showing you each number may be running a different scoring model on a different day. A gap of 20 to 50 points between bureaus is normal, and the direction flips from person to person: plenty of people see Equifax lower and TransUnion higher.

Almost everyone who checks more than one score eventually asks this question, and the usual answers online are unsatisfying. "The bureaus are separate companies" is true and does not tell you what to do about it. What follows is the actual mechanism, in the order it matters, plus how to work out which of your numbers is the one a lender will see.

Why is my TransUnion score lower than Equifax?

Three things have to be identical for two credit scores to be comparable: the data, the model, and the date. When your TransUnion score is lower than your Equifax score, at least one of those three is different, and usually it is the data.

Reporting to the credit bureaus is voluntary. There is no law requiring a lender to furnish your account to Equifax, Experian and TransUnion, and many furnish to only one or two, usually to save money. So a credit card you have paid perfectly for six years might be building history at Equifax and be entirely absent from your TransUnion file. Remove a well aged, well paid account from a file and the score built on that file drops. Nothing is wrong; one bureau simply knows less about you.

Timing compounds it. Even lenders that report to all three do not report on the same day. If your card issuer sent a $2,400 balance to TransUnion on the 3rd and a $400 balance to Equifax on the 18th after you paid it down, your utilization looks completely different at the two bureaus for several weeks. This is the single most common cause of a temporary gap, and it closes on its own.

Why is my TransUnion score higher than Equifax?

Same mechanism, opposite direction. There is no rule that TransUnion runs lower. Which bureau reads higher for you depends entirely on which accounts and which derogatory items each one happens to hold.

A useful way to think about it: the bureau with the least complete picture of you is not automatically the lower one. If the account missing from your TransUnion file is a maxed out card or a collection, TransUnion will read higher than Equifax, because it is missing something that was hurting you. People are often surprised by this and assume the higher number is the "real" one. It is not more real. It is just built on a smaller set of facts.

Why is my TransUnion score lower than Experian?

The causes are identical, with one extra wrinkle worth knowing. Experian's own consumer app shows a FICO Score 8, while most free apps that display a TransUnion number, including Credit Karma, WalletHub and Credit Sesame, show a VantageScore 3.0. So a TransUnion versus Experian comparison is very often a VantageScore versus FICO comparison wearing a bureau disguise.

That is a model difference, not a data difference, and it can easily account for 20 to 50 points on its own. Before concluding that your TransUnion file has a problem, check the fine print on both apps and confirm you are even looking at the same kind of score.

Why do I have different credit scores at all?

Because you do not have one credit score. You have dozens. Each scoring model, calculated against each bureau's version of your report, produces a separate number, and more than two dozen FICO versions are in active use at the same time alongside several VantageScore versions.

Here is what actually varies between any two scores you might be looking at:

  • The bureau. Equifax, Experian and TransUnion each hold their own file, built from whichever lenders chose to report to them.
  • The scoring model. FICO Score 8, FICO Score 2, FICO Auto Score, VantageScore 3.0 and VantageScore 4.0 weigh the same file differently and can be built for different lending decisions.
  • The date. Balances, inquiries and account statuses change constantly. Two scores pulled a week apart are two different snapshots.

Comparing an Experian FICO 8 from Tuesday to a TransUnion VantageScore 3.0 from Friday is three differences stacked on top of each other. Expecting those to match is the mistake, not the gap itself.

Why is my FICO score higher than my credit score in my app?

Usually because the app is not showing you a FICO score. It is showing a VantageScore 3.0, and the two models disagree in specific, predictable ways.

VantageScore 3.0 and 4.0 ignore paid collection accounts entirely, give meaningful weight to rental payment history when it is reported, and can generate a score from a very thin file, sometimes after only a month or two of history. FICO Score 8 does none of those things: it still counts paid collections, gives rental tradelines much less weight, and generally will not produce a score at all until you have an account that has been reporting for six months with recent activity.

So if your file contains a paid collection, or reported rent, or is fairly new, your VantageScore will tend to read higher than your FICO 8. If your file is long, clean and card heavy, FICO 8 often reads higher. Neither is inflated or deflated. They are measuring slightly different things. We go through what the dominant model actually rewards in our explainer on FICO Score 8 and how it compares to FICO 9 and VantageScore.

Which credit score actually matters?

The one belonging to whoever is about to lend you money. That sounds glib, but it is genuinely the only answer, and it is more knowable than most people realize:

  • Conventional mortgage: the Classic FICO versions, FICO Score 2 at Experian, 4 at TransUnion and 5 at Equifax. Lenders pull all three and, for a single applicant, typically use the middle of the three scores. Not the highest, and not an average.
  • Auto loan: usually a FICO Auto Score, which runs on a 250 to 900 scale rather than 300 to 850.
  • Credit card: commonly FICO Score 8 or a FICO Bankcard Score, and issuers vary in which bureau they favor.

The mortgage case is where bureau differences stop being trivia and start costing money. Because underwriters take the middle score of the three, your weakest two bureaus effectively set your rate. Raising the file that is already your strongest does nothing. If a home loan is on the horizon, the thresholds and what they cost are laid out in our guide to what credit score you need to buy a house.

Self-employed applicants get hit twice here, because the middle-score rule arrives alongside a much heavier documentation load. Where a salaried borrower hands over pay stubs, an underwriter will typically ask a freelancer or business owner for two years of returns plus a current profit and loss statement, and pulling one together from a bookkeeping export turned into a proper P&L and balance sheet is worth starting before you apply rather than during underwriting.

Is a 20 to 50 point difference between bureaus normal?

Yes. A spread of 20 to 50 points across bureaus and models is ordinary, and thin files routinely show wider gaps because each individual account carries proportionally more weight when there are only a few of them.

What is not normal is a gap of 100 points or more. That size of difference usually means one bureau is holding something the others are not: a collection, a charge-off, a late payment, or an account that is not yours. At that point the gap is a signal rather than noise, and it is worth pulling the actual reports to find out which one.

How do I find out why my scores are different?

Compare the reports, not the scores. The score is a summary; the report is the evidence, and the difference between two summaries is only explicable from the underlying data.

Pull all three for free at annualcreditreport.com, which is the official federally authorized source and does not ask for a card. Then lay them side by side and look for four things: an account that appears on one report and not another, a different reported balance on the same account, a derogatory mark present on only one, and any hard inquiry or account you do not recognize. One of those four explains the overwhelming majority of bureau gaps.

If you find an account or an inquiry you never authorized, treat it as potential identity theft rather than a scoring curiosity. Dispute it and consider a freeze, which is free at every bureau by federal law and has no effect on your score. Our walkthrough on how to freeze your credit at all three bureaus covers the mechanics.

What if one bureau has an error?

You have the right under the Fair Credit Reporting Act to dispute inaccurate information for free, directly with the bureau, and the bureau generally has 30 days to investigate. You do not need to pay anyone to do this, and no company, including this one, can legitimately remove information that is accurate and current.

The important detail people miss: a dispute filed with one bureau fixes that bureau only. If the same error sits on two reports, you file two disputes. Bureaus do not share corrections with each other, which is the same independence that created the gap in the first place. The full process, including what documentation actually moves an investigation, is in our step by step guide to disputing credit report errors.

Should I be monitoring all three bureaus?

If you are within a year of a mortgage or any large application, yes, because the middle-score rule means a problem sitting on a single bureau can set your rate. Outside of that, watching one bureau consistently is usually enough to catch a real change, as long as you understand that it is one third of the picture.

The trap is watching three different free apps and reading the differences between them as movement. They are not movement. Compare a score against itself over time, same bureau and same model, and treat the gap between providers as a permanent artifact of how the industry is built. We compared which apps report which model and which bureau in our roundup of the most accurate credit score apps, and the paid three-bureau options in the best credit monitoring services.

What to do next

If your bureau scores differ by less than about 50 points, nothing is wrong and there is nothing to fix. Pick the bureau your likely lender uses, watch that one, and ignore the spread. If the gap is larger than that, pull all three reports and find the account that only one bureau knows about, because that account is the entire explanation.

Either way, the levers that raise a score are the same at every bureau: lower reported balances, a clean payment record, and time.
