Marathon Bank on Your Credit Report
In short: Marathon Bank is a state-chartered savings institution supervised by the FDIC and its state regulator headquartered in Wausau, Wisconsin. FDIC certificate 29745 traces to January 1, 1902, a charter older than the FDIC itself. Call-report figures for 06/30/2026 list $261 million in assets spread over 5 FDIC-reported offices. Marathon Bank is the furnisher of record on accounts it originates, so both the §623 route to the bank and the §611 route through the bureaus are available to you. Information that is inaccurate, incomplete, or unverifiable can be disputed under the FCRA. Outcomes depend on what the furnisher can verify, and results vary.

Disputing an original creditor is not the same as disputing a collector
Marathon Bank is an original creditor — the institution whose name was on the account when it was opened. That matters for two reasons. First, the FDCPA, which governs debt collectors, generally does not apply to a creditor collecting its own debt in its own name, so the “debt validation” request that works against a collection agency is not the right tool here. Second, as the furnisher of the tradeline, Marathon Bank has direct obligations under FCRA §623 to investigate a dispute you send it and to correct or delete information it cannot verify as accurate.
Dispute with the bureaus — FCRA §611
File with Equifax, Experian and TransUnion. They must generally investigate within 30 days and tell the furnisher. Free, and you can do it yourself.
Dispute with the furnisher — FCRA §623
Send Marathon Bank a direct written dispute. It must investigate and must not continue reporting information it knows is inaccurate. Keep copies and proof of delivery.
Marathon Bank questions, answered
Is Marathon Bank FDIC-insured, and what is its certificate number?
Yes — deposits are FDIC-insured under certificate 29745. The FDIC record lists Marathon Bank as a state-chartered savings institution supervised by the FDIC and its state regulator headquartered in Wausau, WI, chartered January 1, 1902, holding $261 million across 5 offices at the 06/30/2026 call report.
Who regulates Marathon Bank, and where do I escalate if a dispute fails?
Oversight sits with the FDIC and its state banking regulator. Where both dispute routes come back verified but your own records say otherwise, the CFPB complaint portal is the next step, and §§616–617 of the FCRA preserve a private right of action. Both steps are free, and neither depends on where in Wisconsin you banked with Marathon Bank.
How many credit-card complaints does the CFPB show against Marathon Bank?
No number is published here. When we queried the CFPB credit-card complaint data, no company key matched Marathon Bank exactly, and we will not approximate one by partial-name matching — that routinely pulls in unrelated companies with similar names. Rather than imply a count we cannot source, we leave it out. The database is public and searchable at consumerfinance.gov.
How long can a Marathon Bank charge-off stay on my credit report?
The FCRA ceiling is roughly seven years from the date of first delinquency on the Marathon Bank account. Charging it off, selling it, or moving it to a servicer does not restart that clock. If the date of first delinquency drifts forward, that is re-aging — itself an FCRA violation worth disputing.
Should I dispute with Marathon Bank directly or with the collection agency?
Marathon Bank is the original creditor and holds the underlying file — application, statements, posting history. A collector typically receives a data file, not the original paperwork. A §623 dispute to Marathon Bank puts the question to the party that can actually check it against source documents.
Does Marathon Bank report to all three credit bureaus?
There is no legal requirement to furnish to every bureau, and Marathon Bank, operating 5 offices, may not. Pull all three files and compare. A balance that differs between bureaus usually reflects different refresh dates; a status or first-delinquency date that differs is the real signal worth disputing with Marathon Bank.
Marathon Bank changed names or was acquired — why does my report show two accounts?
One account showing twice is a classic conversion artifact. Marathon Bank has operated since 1902, and a charter that old has usually been through at least one core-system migration. An account may legitimately appear under a predecessor name, but the same debt must not report twice with two balances. Dispute the duplicate and name both tradelines.
Can I dispute a Marathon Bank account myself without paying anyone?
Yes. Both the §611 bureau dispute and the §623 direct dispute to Marathon Bank are free and available to you. No company can do anything for you that you cannot do yourself, and nobody can lawfully promise you a specific result. Anything accurate and timely stays on the report.
Where is Marathon Bank headquartered, and does that affect my dispute?
The home office is in Wausau, Wisconsin, across 5 FDIC-reported locations. Your FCRA rights are federal and identical in every state; what the headquarters determines is the state authority sitting alongside the FDIC and its state banking regulator if you need to escalate.
