I have had U.S. credit cards since 2024 and recently received an ITIN, but while Equifax updated my credit file with the new number, Experian and TransUnion only sent back reports still listing my passport number; what steps should I take to force these two bureaus to link my credit history to my ITIN?
You can submit formal disputes to the credit bureaus and your creditors to correct your information, but the documents do not confirm a direct way to force Experian and TransUnion to manually link your passport-based history to your new ITIN.
You are taking the right steps by monitoring your credit after receiving your ITIN. Once your information is updated, you can request your Experian credit report in writing using your ITIN to verify your history.
The provided documents do not establish whether credit bureaus are legally or procedurally obligated to automatically link a passport-based credit file to a newly issued ITIN without a manual consumer dispute.
The documents also do not confirm whether Experian and TransUnion permit a consumer to manually update or link an ITIN to an existing credit file established under a passport number.
Finally, the documents do not provide TransUnion or Equifax's specific procedures, requirements, or mailing addresses for requesting or updating an ITIN-based credit report.
