A credit inquiry can look tiny on a credit report. Just a line with a company name and a date. Yet that one line can raise a much bigger question. Who asked to see personal credit information, and why?
Sometimes the answer is simple. A forgotten loan application, a store financing offer, or a bank that checked credit with permission. Other times, the inquiry belongs to a company that has never been contacted. That can point to identity theft, a reporting mistake, or a business that pulled credit without proper authorization.
Taking action quickly often makes life easier. A clear letter creates a written record, asks for an explanation, and gives the credit bureau or company a fair chance to fix the issue before the problem grows into something far more stressful.
Sample Letters of Unauthorized Credit Inquiry
A short, polite letter often gets better results than an emotional one. The samples below cover different situations, from contacting a credit bureau to writing directly to a lender that appeared on a credit report without permission.
1. Letter to a Credit Bureau Requesting Removal of an Unauthorized Inquiry
Subject: Request to Remove Unauthorized Credit Inquiry
Dear Experian Dispute Department,
I recently reviewed my credit report and noticed a credit inquiry from Bright Horizon Lending dated March 18, 2026.
I did not apply for credit with this company, nor did I authorize anyone to access my credit file on my behalf. Because of this, I believe the inquiry may have been made in error or without my permission.
Please investigate this matter and remove the inquiry if you determine that it was not properly authorized. If additional information is required, kindly let me know.
Attached are copies of my identification and a copy of the relevant section of my credit report for reference.
Thank you for your prompt attention to this matter. I look forward to your written response.
Sincerely,
Michael Johnson
2. Letter to the Company That Made the Inquiry
Subject: Unauthorized Credit Inquiry
Dear Credit Department,
I recently obtained a copy of my credit report and noticed that your company accessed my credit report on April 9, 2026.
I have no record of applying for credit, financing, or any other service with your business. As a result, I am requesting a written explanation showing the legal basis for this inquiry.
If this inquiry was made in error, please contact the credit reporting agencies and request its removal as soon as possible.
Please respond within 30 days with either documentation proving my authorization or confirmation that the inquiry has been withdrawn.
Thank you for your cooperation.
Respectfully,
Amanda Lewis
3. Identity Theft Related Unauthorized Inquiry Letter
Subject: Unauthorized Credit Inquiry Due to Suspected Identity Theft
Dear Dispute Department,
I am writing to dispute an inquiry listed on my credit report from Silver Creek Financial dated February 21, 2026.
I believe this inquiry resulted from identity theft because I did not request any credit from this company. I have filed an identity theft report with the appropriate authorities and have enclosed supporting documentation.
Please investigate this inquiry and remove it from my credit report if you determine that it resulted from fraudulent activity.
Kindly confirm in writing once your investigation has been completed.
Thank you for your assistance.
Sincerely,
Rachel Evans
4. Follow-Up Letter After No Response
Subject: Second Request Regarding Unauthorized Credit Inquiry
Dear Customer Relations Department,
On May 2, 2026, I wrote concerning an unauthorized credit inquiry made by your company. As of today, I have not received a response.
The inquiry remains on my credit report, and I continue to dispute its validity because I never authorized your company to review my credit information.
Please investigate this issue immediately and provide either documentation showing my authorization or confirmation that the inquiry has been removed.
I would appreciate receiving your written response within 15 business days.
Thank you for your prompt attention.
Sincerely,
David Brooks

5. Letter Requesting Proof of Authorization
Subject: Request for Documentation Supporting Credit Inquiry
Dear Credit Services Department,
I recently obtained a copy of my credit report and noticed that your company conducted a credit inquiry on June 3, 2026.
I do not recall submitting an application, completing an online form, signing any paperwork, or giving written or electronic permission for your company to access my credit file. Because I have no record of requesting credit or any related service from your organization, I am concerned that this inquiry may have been made in error or without my authorization.
To help resolve this matter, I respectfully request copies of any records showing that I authorized your company to obtain my credit report. If such authorization exists, please provide any documentation available, including:
- A signed credit application.
- An electronic consent record.
- An online application showing the submission date and time.
- Any agreement or document explaining the purpose of the inquiry.
- Any additional records linking this inquiry to me.
If your investigation shows that no valid authorization exists, I ask that you promptly notify the applicable credit reporting agencies and request that this inquiry be removed from my credit file. I would also appreciate written confirmation once those steps have been completed.

6. Letter Disputing an Inquiry After Loan Shopping
Subject: Dispute of Incorrect Credit Inquiry
Dear Equifax Dispute Department,
While reviewing my credit report, I noticed an inquiry from Green Valley Finance dated July 12, 2026.
Although I recently compared loan rates with several lenders, I did not submit a credit application to Green Valley Finance, nor did I authorize the company to obtain my credit report. My discussions with other lenders were limited to rate comparisons, and I was careful to provide permission only where necessary.
For that reason, I believe this inquiry may have been added by mistake or because my information was shared without my knowledge or consent. I respectfully request that you investigate the matter and determine whether Green Valley Finance had a permissible purpose for accessing my credit report.
If the company cannot verify that I authorized the inquiry, please remove it from my credit file and notify me once the correction has been completed.
Enclosed are copies of my identification and the relevant page of my credit report to assist with your investigation.
Thank you for your attention to this dispute. I appreciate your prompt assistance and look forward to your written response.
Respectfully,
Jason Miller
7. Letter After a Dealership Credit Pull Without Permission
Subject: Unauthorized Credit Check at Vehicle Dealership
Dear Finance Manager,
I visited your dealership on August 6, 2026, to ask questions about available vehicles and gather information about pricing and features. During my visit, I did not complete a financing application, sign any authorization forms, or request that my credit report be accessed for financing purposes.
After reviewing my credit report, I was surprised to discover that your dealership conducted a credit inquiry on that same date.
Please explain why this inquiry was made and provide copies of any documents or electronic records showing that I gave permission for my credit report to be obtained. If no such authorization exists, I request that your dealership immediately contact the appropriate credit reporting agencies and request removal of the inquiry.
Once the correction has been initiated, I would appreciate written confirmation for my records. I also ask that you provide the name of the lender, if any, that received my information as part of this inquiry.
Thank you for your prompt attention to this matter. I hope this issue can be resolved quickly and without further action.
Sincerely,
Sarah Bennett
8. Letter to a Bank After an Unknown Credit Inquiry
Subject: Credit Inquiry Dispute
Dear Customer Service Department,
I recently reviewed my credit report and noticed that your bank accessed my credit report on September 1, 2026.
I have never applied for a loan, credit card, mortgage, line of credit, or any other financial product through your institution. I also have no existing business relationship with your bank that would reasonably require a review of my credit history.
Because I cannot identify any legitimate reason for this inquiry, I believe it may have resulted from an administrative error, a case of mistaken identity, or an unauthorized use of my personal information.
Please investigate this matter thoroughly and provide written confirmation explaining the reason for the inquiry. If your records do not show valid authorization, I respectfully request that you notify the relevant credit reporting agencies and arrange for the inquiry to be removed from my credit file.
I appreciate your cooperation and ask that you respond within 30 days so this issue can be resolved promptly.
Thank you for your time and consideration.
Respectfully,
Thomas Reed
9. Letter Requesting Investigation After Multiple Unauthorized Inquiries
Subject: Request to Investigate Multiple Unauthorized Credit Inquiries
Dear TransUnion Dispute Department,
I recently obtained a copy of my credit report and noticed several inquiries that I do not recognize.
The inquiries include:
- Summit Credit Solutions dated April 14, 2026
- Northern Trust Finance dated April 18, 2026
- Metro Cash Lending dated April 22, 2026
I did not apply for credit with any of these businesses, nor did I authorize anyone else to do so on my behalf. I have carefully reviewed my recent financial activity and cannot identify any legitimate transaction that would explain these inquiries.
Because several unfamiliar inquiries appeared within a relatively short period, I am concerned that my personal information may have been used without my knowledge. I would appreciate a thorough investigation into each inquiry to determine whether there was a permissible purpose for accessing my credit report.
If any of these inquiries cannot be verified as authorized, please remove them from my credit file and provide written confirmation once your investigation has been completed.
Attached are copies of my identification and the relevant pages of my credit report to assist with your review.
Thank you for your attention to this matter. I appreciate your assistance and look forward to your response.
Sincerely,
Olivia Turner
10. Final Demand Letter Before Filing a Regulatory Complaint
Subject: Final Request for Removal of Unauthorized Credit Inquiry
Dear Compliance Department,
This letter serves as my final request regarding the unauthorized credit inquiry your company placed on my credit report.
Despite my previous correspondence, I have not received any documentation demonstrating that I authorized your company to access my credit report. The disputed inquiry continues to appear on my credit file, and the matter remains unresolved despite the time that has passed.
I once again request that you provide evidence supporting your legal authority to conduct this inquiry. If you cannot produce documentation showing my authorization, I ask that you immediately notify all applicable credit reporting agencies and request removal of the inquiry from my credit history.
Please provide written confirmation once these actions have been completed. If this matter is not resolved within 15 business days of receiving this letter, I intend to pursue the issue through the appropriate regulatory agencies and any other remedies available under applicable law.
I would prefer to resolve this matter directly and without further escalation. Thank you for your prompt attention, and I look forward to your response.
Sincerely,
Daniel Harris
Wrapping Up
An unauthorized credit inquiry may seem small, though it deserves attention. Whether the cause is a reporting mistake, identity theft, or a company acting without proper permission, putting concerns in writing creates a clear record and often speeds up the investigation. Keeping copies of every letter, delivery receipt, and response also makes it much easier to show what steps have already been taken if the dispute continues.
The strongest letter is usually the simplest one. State the facts, identify the inquiry, explain that permission was never given, and ask for a specific outcome. A few careful minutes spent sending the right letter today can save weeks of frustration later.
