Equifax is a big-name credit reporting agency, but that doesn't necessarily mean it's always accurate. If you're relying on Equifax for your credit score, it's important to check your report regularly for errors. Otherwise, you could unnecessarily pay higher interest rates or receive unjust denials for loans. Luckily, it's relatively easy to dispute errors on your credit report. You can either do it yourself or hire a professional to help you.
