How to Fix: DU Error Code 331

Verify Your Personal Information

As already mentioned, if the personal information you have added to the credit report is not correct or valid, then your request for a credit report will be automatically denied – unsuccessful.

Therefore, verify your personal information check for spelling mistakes and errors, and make sure the information is valid.

Submit Credit Request Again

The issue can be about the DU system or credit reporting agency. If it is big, they might announce it publicly, or if it isn’t, then it will not take time to resolve.

If the second one is the case, then you should try submitting the credit request again after some time, after a couple of hours, or at a different time of the day.

Additionally, we have presented a bunch of more points below that you must check out while submitting the credit request:

You must check if you are submitting the credit report request to the right credit reporting agency.
Your credit report request format must be correct.
You must be submitting the credit report request with the right browser information.
