What do I need to open an account with First Interstate Bank?

There are several things you will need to refer to - and provide - during the account opening process:

  • You'll be asked for your U.S. Social Security number and valid form of identification including: Driver's license, State ID, Military ID, Tribal ID, or Passport.
  • You will need to provide personal information, a current and former mailing address (es) if you have not lived at your current address for a least 2 years..
  • You will also need a credit card, debit card, U.S. Checking or Savings Account to fund your new account(s).

If you are not a U.S. Citizen or U.S. Resident Alien and do not have this information, we will be unable to enroll you online. Please visit one of our branches for assistance.

Is my online application secure?

First Interstate Bank uses encryption for online security. Encryption technology helps provide secure transmission of information along the Internet by encoding the transmitted data using a mathematical formula to scramble the data. Without a corresponding "decoder," the transmission would look like nonsense text and would be unusable.

Encryption technology can be used for a host of applications, including electronic commerce (sending credit card numbers for orders or transmitting account information), e-mail messages and sensitive documents.

Encryption is utilized with the transmission of data from one party to another. The sender encodes the data by scrambling it and then sends it on. The receiver must decode the data with the correct "decoder" in order to read and use it. The effectiveness (or level of security) for encryption is measured in terms of how long the key is - the longer the key, the longer it would take for someone without the correct "decoder" to break the code. The length of the key is measured in bits (e.g., 40-bit encryption, the level of encryption used with many ordinary browsers, versus 128-bit encryption, the level of encryption required to use this application).

What information do I need to open a joint account?

You'll need the same information that's required when opening an individual account-but you'll need it for both applicants. For details, select "What do I need to open an account with First Interstate Bank?" above. Please note that each applicant will need to sign the signature card.

Why is personal information required to open an account online?

Your application is processed subject to our ability to verify your identity. (For more information, select "What do I need to open an account with First Interstate Bank?" above.)

Is a minimum deposit required to open an account online?

Please refer to our account selection page for product minimums.

When is the opening deposit processed?

On the third business day after you have completed the micro-deposit verification or the second business day for credit card funding. If you currently are a First Interstate Bank customer and are transferring money from an existing account with us, the transfer will occur on the next business day.

Can I change the information on my account application?

New customers have the option to edit account information prior to submitting the information to First Interstate Bank. Existing customers can not edit data based information. Simply click on the "Edit" button above the grouping of information you would like to change, and you will be permitted to change your input.
