MountainOne Bank on Your Credit Report
In short: MountainOne Bank is a state-chartered bank that is not a member of the Federal Reserve System, supervised by the FDIC and its state regulator headquartered in North Adams, Massachusetts. The charter behind FDIC certificate 90253 dates to January 1, 1848 — a nineteenth-century charter, which means its paper records long predate electronic furnishing and conversions have had decades to introduce artifacts. As of the 06/30/2026 call report, MountainOne Bank held $1.08 billion in assets and operated 6 FDIC-reported offices. MountainOne 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 open 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.

How MountainOne Bank appears on your credit report
MountainOne Bank is an original creditor, not a collector, and that changes the mechanics. With 6 offices, the branch that opened the account is often still the fastest route to the original paperwork — ask for it by branch, not just by account number. Name the account by its last four digits and open date, state the one field you believe is wrong, and file the bureau dispute at the same time. Outcomes depend entirely on what the records show.

Grounds to dispute a MountainOne Bank entry
Each of these is a reason a MountainOne Bank tradeline may be inaccurate or unverifiable. None of them assures removal — they are the angles worth checking on your own report.
- ◆Payment made in person in North Adams but applied to a different MountainOne Bank account
- ◆Paid-in-full MountainOne Bank balance still reporting as outstanding
- ◆Duplicate MountainOne Bank entry created by a servicing-platform change
- ◆Account balance or credit limit reported incorrectly
- ◆Payment reported late when it was made inside the grace period
- ◆Date of first delinquency re-aged to extend how long it can report
- ◆Account still reporting as open after it was closed, or vice versa
- ◆Duplicate tradeline for the same account after an internal transfer
- ◆Account belongs to someone else with a similar name, or is the result of identity theft
Disputing an original creditor is not the same as disputing a collector
MountainOne 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, MountainOne 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 MountainOne Bank a direct written dispute. It must investigate and must not continue reporting information it knows is inaccurate. Keep copies and proof of delivery.
MountainOne Bank questions, answered
Is MountainOne Bank FDIC-insured, and what is its certificate number?
Yes — deposits are FDIC-insured under certificate 90253. That record lists MountainOne Bank as a state-chartered bank that is not a member of the Federal Reserve System, supervised by the FDIC and its state regulator headquartered in North Adams, MA, chartered January 1, 1848, with $1.08 billion in assets across 6 FDIC-reported offices on the 06/30/2026 call report.
Who regulates MountainOne Bank, and where do I escalate if a dispute fails?
As a state-chartered bank that is not a member of the Federal Reserve System, supervised by the FDIC and its state regulator, MountainOne Bank answers primarily to that regulator. Where a §611 and a §623 dispute both come back verified against documentation you hold, escalate to the CFPB, and note that FCRA §§616–617 create a private right of action. You do not need to hire anyone to take either step.
How many credit-card complaints does the CFPB show against MountainOne Bank?
No number is published here. When we queried the CFPB credit-card complaint data, no company key matched MountainOne 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 MountainOne Bank charge-off stay on my credit report?
The FCRA ceiling is roughly seven years measured from the date of first delinquency on the MountainOne Bank account. Charging the balance off, selling it, or moving it to another servicer does not restart that clock. If the date of first delinquency moves forward, that is re-aging — itself an FCRA violation worth disputing.
What is the difference between disputing with MountainOne Bank and disputing with a collector?
MountainOne Bank is the original creditor and holds the underlying file — application, statements, posting history. Collectors typically receive a data file, not the original paperwork. Disputing directly with MountainOne Bank under §623 puts the question to the party that can actually check it.
Does MountainOne Bank report to all three credit bureaus?
There is no legal requirement to report to every bureau, and banks this size often do not. Compare all three files first. With MountainOne Bank, a varying balance usually reflects different refresh dates; a varying account status or date of first delinquency is the real signal.
MountainOne Bank was acquired or changed names — why does my report show two accounts?
A single account showing twice is a classic conversion artifact. MountainOne Bank has operated since 1848, and charters that old have usually been through at least one core-system migration. One 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 MountainOne Bank account myself without paying anyone?
Yes. Both the §611 bureau dispute and the §623 direct dispute to MountainOne Bank are free and available to you directly. No company can do anything for you that you cannot do yourself, and nobody can lawfully promise a specific result. Anything accurate and timely stays on the report.
Where is MountainOne Bank headquartered, and does that affect my dispute?
MountainOne Bank is headquartered in North Adams, Massachusetts, with 6 FDIC-reported offices. Headquarters does not change your federal rights — the FCRA applies the same way everywhere — but it does tell you which state banking regulator shares oversight, which matters if you escalate past the CFPB.
