When your score falls, compare the new report with an older copy. Look for a new enquiry, increased card balance, new account, late-payment month, changed status or shortened account age. This is more useful than guessing which scoring factor matters most.
Read payment history chronologically
Scan each account month by month. A DPD value can reflect a real late payment or a reporting error. Compare it with bank payment proof and lender statements. Dispute only when the data is inaccurate.
Understand closed accounts
A closed account can remain on the report as historical information. “Closed” is not the same as “deleted”. A settled account can carry a different meaning from a fully paid closure. Check the status wording.
Joint and guaranteed accounts
Borrowers sometimes discover a loan because they were co-borrower or guarantor. Review the ownership type. Legal responsibility can exist even when someone else used the money.
Enquiry versus account
An enquiry shows that a lender accessed your report for a credit application. It does not mean the loan was granted. A new account should appear separately after disbursal/reporting.
Build an error log
For each suspected error, record bureau, lender, account fragment, field, incorrect value, correct value and evidence. Submit one precise dispute rather than “my score is wrong”.
After a dispute
Re-download the report and verify the field. Do not close the case merely because the score changed. The goal is accurate data.
Decision rule
Read the report like a ledger of credit relationships. Scores can vary, but accounts, balances, payment history and enquiries give you specific actions: repay, correct or wait for normal reporting.
