ChexSystems freeze, dispute and report request: where each one goes

A ChexSystems freeze can be requested three ways, and ChexSystems lists all of them on its Place a Security Freeze page: online in the ChexSystems Consumer Portal, by phone at 800-887-7652, or by a written request mailed to Chex Systems, Inc., Attn: Security Freeze Department, PO Box 583399, Minneapolis, MN 55458. We read that page, and the others linked below, on 13 Nov 2026.

The CFPB's list of consumer reporting companies (current as of January 2025) describes Chex Systems, Inc. as a company that provides account verification services primarily for financial institutions and reports data on checking account applications, openings and closures. Its file is separate from the credit files at Equifax, Experian and TransUnion, so it takes its own freeze.

One PO box, two attention lines

Every mailing address on the ChexSystems pages we read is the same box in Minneapolis. What changes is the line above it, the phone number and whether there is a form.

What you are asking for	Address it to	By mail you send	Phone ChexSystems lists	Source, read 13 Nov 2026
Security freeze: place, lift, remove, new PIN	Attn: Security Freeze Department	A written request and three identity documents	800-887-7652	Place a Security Freeze
Dispute of something in your report	Attn: Consumer Relations	Request for Reinvestigation Form and three identity documents	800-428-9623	Dispute
Copy of your consumer disclosure report	Attn: Consumer Relations	Consumer Request for Disclosure Form and three identity documents	800-428-9623	Consumer Disclosure

All three go to Chex Systems, Inc., PO Box 583399, Minneapolis, MN 55458. The site says of this box: "This address is a mailing address only. Personnel are not available at this address to provide consumer assistance."

The two phone lines keep different hours. On its Contact Us page, ChexSystems says the automated system on both runs 24 hours a day. Security freeze representatives are available 7:00am to 11:00pm Central Time, Monday through Friday. Consumer Relations representatives are available 8:00am to 7:00pm Central Time, Monday through Friday.

What a ChexSystems freeze does

In ChexSystems's words on its Security Freeze Information page, a security freeze "prohibits a consumer reporting agency from releasing any information in your consumer file without your expressed authorization." It "is designed to prevent approval of checking, savings, credit accounts, loans, or other services from being approved in your name without your consent."

The same page is plain about the cost of that protection: a freeze "may delay or prevent timely approval from any user of your consumer report that you wish to do business with. The third party will receive a message indicating that you have blocked your information." You can ask for a temporary lift when you want to open an account.

Three more things ChexSystems states:

• Who can ask. "All consumers who reside in the United States have the right to place a security freeze on their file." You must be 18 or older to communicate with ChexSystems.
• What it covers. Only this file. Requests "will be applied only to your ChexSystems consumer report."
• The PIN. You receive a unique Personal Identification Number "by mail or delivered to the ChexSystems Consumer Portal." The PIN is required to apply a temporary lift, to remove the freeze or to change personal identifying information.

On fees, the Notice of Rights page says: "Chex Systems, Inc. does not charge a fee for placing or lifting a security freeze, however, we reserve the right to apply fees as allowed by each state."

Freezing by mail: a letter, not a form

ChexSystems has forms for disputes and for report requests. It has none for a freeze. Under "Submit Request by Other Methods," the freeze page asks for correspondence that includes:

• your full name,
• your current address,
• your date of birth,
• your Social Security number.

"To authenticate your identity," it asks you to include three enclosures:

• a copy of a State Identification Card or Driver's License "in color clearly showing the front and back of the document,"
• a copy of a Social Security card,
• proof of address "dated within the last 90 days such as a utility bill."

After that the page says only: "Once your request has been received, ChexSystems will mail a response to you." The ChexSystems pages we read do not give a processing time for a freeze requested by mail, so we do not state one.

A short letter covers what the page asks for:

[Your full name]
[Your current address]
[Date]

Chex Systems, Inc.
Attn: Security Freeze Department
PO Box 583399
Minneapolis, MN 55458

Please place a security freeze on my ChexSystems consumer file.

Full name: [name]
Current address: [address]
Date of birth: [date]
Social Security number: [number]

Enclosed: a color copy of my driver's license (front and back), a copy of my Social Security card, and a utility bill dated within the last 90 days.

[Your name]

Freezing for a child or for someone else

This is the case ChexSystems does not take online or by phone: "To place a security freeze on behalf of someone other than yourself, you must submit the request in writing by mail."

For a minor, the parent or legal guardian sends the request with:

• a copy of the minor's birth certificate,
• a legible copy of the minor's Social Security card,
• a legible color copy of the parent or guardian's driver's license or state identification card, front and back,
• proof of address for the parent or guardian, such as a pay stub or utility bill,
• a court or other legally binding document confirming guardianship, if the sender's name is not on the birth certificate.

For an adult, ChexSystems asks for a notarized Power of Attorney or a notarized copy of specific written instructions signed by the consumer, plus identity documents for both people. A notarized document is an original with a notary's seal. That is a packet to assemble and mail yourself, not one to upload to a mailing service.

What federal law says, and what it does not settle here

The Fair Credit Reporting Act has a national security freeze rule in 15 U.S.C. 1681c-1(i). For that subsection, the statute says "consumer reporting agency" means an agency described in section 1681a(p). Section 1681a(p) describes agencies that compile both public record information and credit account information on consumers nationwide. The same section defines a different category in subsection (x), the "nationwide specialty consumer reporting agency," and lists "check writing history" among the kinds of files those agencies keep.

ChexSystems's freeze pages do not cite the federal subsection. They say that all consumers who reside in the United States have the right to place a freeze on their file, and that the company "abides by state security freeze regulations." So this page reports what ChexSystems says it does, and does not tell you which law gives you the right in your state. The Notice of Rights page links its notices by state.

Disputing what is in your ChexSystems report

ChexSystems takes disputes in the Consumer Portal, by phone at 800-428-9623, or by mail on its Request for Reinvestigation Form. The form is two pages. For each item it asks for the source of the disputed information, the date listed on the item, the type of information and why you dispute it. It ends with a signature line and a date line.

The Dispute page gives the timing: "Reinvestigations are usually completed within 30 days (21 days for residents of Maine)." If you send more information while it is pending, "the time frame may be extended by up to 15 days." That matches the Fair Credit Reporting Act, which gives a consumer reporting agency until the end of the 30-day period that begins when it receives the dispute, with up to 15 more days if you send relevant information during that period (15 U.S.C. 1681i).

Supporting documents are optional. ChexSystems names an identity theft affidavit, a police report, account statements, paid or settled in full letters and a death certificate as examples. Sending a dispute does not mean the item will be changed or removed.

Getting your ChexSystems report first

You cannot dispute what you have not seen. ChexSystems says it provides its consumer disclosure reports at no charge, and that under the Fair Credit Reporting Act you can ask for one at a minimum once every 12 months. It takes the request in the portal, by phone at 800-428-9623 or on its Consumer Request for Disclosure Form, which asks for your driver's license number and the addresses of other residences in the past five years, and also ends with a signature line.

Visually impaired consumers can call 855-472-2911 to request the report in Braille, large print or audio CD.

What we could not find: a fax number

Some guides to ChexSystems freezes, including a help page from an identity protection company dated 28 Oct 2026, say requests can be sent by "mail, fax, or telephone." The three ChexSystems pages that list its contact routes (Place a Security Freeze, Security Freeze Information and Contact Us) give the portal, a phone number and the mailing address. None gives a fax number.

The Security Freeze Information page does mention email, under a heading for Hawaii and New Hampshire residents, and warns in the same breath: "your personal identifying information should not be included in email communications."

Mailing a freeze request with Certisent

Because a ChexSystems freeze request is a letter with no form and no signature line, it can go through Certisent.

1. Write the letter. The sample above has what ChexSystems asks for.
2. Put the letter and copies of your three documents in one PDF. Those pages carry your Social Security number and ID, and they pass through our system to be printed. If you would rather not upload them, the Consumer Portal and the phone line need no paper at all.
3. We print in black and white only. ChexSystems asks for the ID copy in color, so a black and white copy may not meet its request. If you want to send the color copy, print and mail the packet yourself, or use the Consumer Portal or the phone line.
4. The recipient is already set: Chex Systems, Inc., Attn: Security Freeze Department, PO Box 583399, Minneapolis, MN 55458. Add your own name and address as the sender.
5. Check the preview and pay $14.99. We print the pages and hand them to USPS as Certified Mail, and you get the tracking number, a proof of mailing and the electronic return receipt.

Two things we do not mail. The Request for Reinvestigation Form and the Consumer Request for Disclosure Form each end with a signature line, and ChexSystems does not say whether it accepts a printed image of a signature. Print those forms, sign them in ink and mail them yourself to Attn: Consumer Relations at the same box. And a packet with a notarized document has to be the original.

We cannot promise a delivery date. We are not a credit repair organization. You pay for mailing, nothing else, and what the letter says is up to you.
