How to check First Interstate Bancsystem yourself
- Use contact details you found yourself. Go to the company's own website or the number on your card or statement - never a number or link from a text, email or caller.
- Check its licence. Banks should be on the FDIC's BankFind; credit unions with the NCUA. Many apps are not banks themselves - check which bank holds your money.
- Read the latest complaints. Look for the same problem again and again in the complaint log, and at how they were answered.
- Read people's own experiences. See what others say about First Interstate Bancsystem, and add yours.
- Get everything in writing before you pay, sign or share anything.

Your rights with banks & credit unions
For electronic transfers and debit cards, Regulation E gives you 60 days from the statement to report an error or unauthorized transaction; the bank must investigate, generally within 10 business days or give provisional credit while it takes longer. Reporting a lost card quickly limits what you can lose. Deposits at insured banks are protected up to $250,000 by the FDIC (credit unions by the NCUA).
