First Interstate Bank on Your Credit Report
In short: First Interstate Bank operates under FDIC certificate 1105 from Billings, Montana, on a charter established in 1916. It is a regional bank serving the Rocky Mountain and upper Midwest states through community branch banking, consumer lending and card products. Information that is inaccurate, incomplete, or unverifiable can be disputed under the FCRA. Outcomes depend on what the furnisher can verify, and results vary.

What makes this creditor different
First Interstate operates under FDIC certificate 1105, chartered in Billings, MT and established October 9, 1916 — 110 years of continuous charter history. Since January 2025 the CFPB has logged 11 credit-card complaints naming First Interstate, the largest share of them about a disputed purchase on a statement (6).
How First Interstate appears on your credit report
First Interstate has grown substantially by acquiring community banks across its footprint. When an acquired bank's portfolio converts, the consumer's account number frequently changes and the tradeline can re-report with a new open date rather than the original one. An open date that resets at conversion is a meaningful error, because account age is a scoring factor — the correct open date is the date you opened the original account, not the date the systems merged.

Grounds to dispute a First Interstate entry
Each of these is a reason a First Interstate tradeline may be inaccurate or unverifiable. None of them assures removal — they are the angles worth checking on your own report.
- ◆Open date reset to a portfolio-conversion date rather than the original account opening
- ◆Acquired-bank account reporting separately from its converted successor
- ◆Payment history gap across a core-system conversion
- ◆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
First Interstate 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, First Interstate 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 First Interstate Bank a direct written dispute. It must investigate and must not continue reporting information it knows is inaccurate. Keep copies and proof of delivery.
First Interstate Bank questions, answered
Is First Interstate FDIC-insured?
Yes. First Interstate appears in the FDIC's BankFind institution directory under certificate 1105, headquartered in Billings, MT, with a charter established October 9, 1916.
What do people complain to the CFPB about most with First Interstate?
Of the 11 credit-card complaints naming First Interstate in the CFPB's public database since January 2025, the largest single category is "Problem with a purchase shown on your statement" at 6, followed by "Closing your account" (2). These are public complaint statistics about the company, not a prediction about any individual account. Snapshot taken 2026-10-17.
How do I dispute a First Interstate account on my credit report?
You can dispute with Equifax, Experian and TransUnion under FCRA §611, and you can dispute directly with First Interstate as the furnisher under FCRA §623. Both routes are free and you can do them yourself. Put it in writing, identify the account by its last four digits and open date, state exactly what is inaccurate, and keep copies. Whether an item changes depends on what the furnisher can verify, and results vary.
How long can a First Interstate delinquency stay on my report?
A delinquent or charged-off account can generally report for up to seven years from the date of first delinquency — the original missed payment that was never brought current. That clock does not restart because the account was charged off, sold, or transferred. If the date of first delinquency has been moved forward, that re-aging is itself a reportable FCRA inaccuracy.
