What is a 'mixed file'?
Review all questions and explanations
- What is a 'mixed file'?
Answer: Two consumers' information merged into one file — typically someone with a same or similar name
That is the CFPB's own definition. A same or similar name is the signature; a foreign address attached to foreign accounts is the pattern to look for.
- What is the strongest first step when someone else's accounts appear on your report?
Answer: Build a line-by-line inventory of which entries are and are not yours, then dispute the foreign ones specifically
A vague 'not mine' can be terminated as frivolous. A table naming each foreign entry, fragment and shared address is what makes the dispute investigable.
- Can a CPN or 'new credit identity' fix a mixed file?
Answer: No — altering your identification to conceal accurate information is prohibited by federal law
15 U.S.C. 1679b(a)(2) prohibits statements intended to alter your identification to conceal accurate adverse information. A sold 'new number' is fraud.
Your take-away checklist
- Pull your report and mark every entry you do not recognize as a candidate foreign item.
- For each candidate, record: furnisher name, account fragment, date opened, attached address.
- Note which foreign entries share a foreign address or a similar-name variant — that is the pattern.
- Rule out your own accounts: match each candidate against your records by fragment and date.
- Separate the causes: wrong identity data, a same-or-similar-name mixed file, or possible theft.
- Request a file disclosure to learn each foreign entry's source.
- Draft the dispute naming each foreign entry by account fragment and the shared foreign address.
- Keep the full inventory — it is the evidence the dispute rests on.
Read the source, keep the context.
