Reasons for iowastate's TrustScore of 1%

The website under review, https://www.iowastate.bank/, presents itself as a full‑service online bank named Iowa State Bank (ISB) servicing communities in Northwest Iowa. The site advertises personal and business checking and savings accounts, loans (consumer, home, agriculture), mobile banking (including Apple Pay, Google Pay, Samsung Pay), Zelle®, eStatements, bill‐pay and other digital banking features. 
It also provides a list of local branch locations (e.g., Brunsville, Hinton, Holstein, Hull, Ireton, Le Mars, Melvin, Merrill, Orange City, Paullina, Remsen, Sanborn, Sheldon, Sibley) in Iowa. 
The site claims to offer 24/7 digital banking convenience and bolster community banking values. 
You asked whether the website is a scam—based on available information the picture is mixed. On one hand, the site mimics a legitimate bank site, lists many typical banking services, and provides location information and routing numbers. On the other hand, there are red flags: you suspected it is a scam; we could not verify full regulatory/licensing details easily; and in general any online bank asking for deposits or onboarding without extensive verification should be treated with caution.
In this review I will walk you through key points, pros and cons, and my final evaluation of legitimacy.

Additional Information about iowastate

To determine whether iowastate.bank is legitimately a bank or a scam, we consider several factors: regulatory status, digital footprint, risk environment, and user jurisdiction.

Regulatory status & transparency:

• A legitimate U.S. bank must have a charter (state or federal), must be insured by the U.S. federal deposit insurance (FDIC), and must list disclosures (Member FDIC, Equal Housing Lender). The site does include an “External link to FDIC website / Equal housing lender” reference. 

• The routing number 073922432 appears in multiple places on the site. 

• The history page claims the bank has assets and multiple branches in Northwest Iowa since 1988. This is plausible for a small regional bank. 
  Thus, there are signs consistent with legitimacy.

Digital footprint and domain considerations:

• The domain “iowastate.bank” gives the impression of a bank identity. .bank domains are heavily regulated and only available to verified banking institutions. However, just having the domain is not a full guarantee of operational integrity.

• The site appears professionally built with appropriate banking services listed.

• However, I did not locate an independent verification in public sources (within my searches) that this bank is known in major U.S. regulatory registers with that domain for global/international depositors. That means if you are dealing from Nigeria, you may not have regulatory protection, and your funds may not be insured in your jurisdiction.

Risk environment for you (outside the U.S.):

• If you are in Nigeria and deposit/transfer funds into an account at this bank, you may face several risks: currency/transfer issues, regulatory jurisdiction (U.S. bank subject to U.S. laws, but you may not have direct consumer protection), cross‐border fraud/investment scam risk.

• If the bank is genuine but your country’s banking frameworks treat it as a foreign (unfamiliar) bank, you may be on your own in case of a dispute.

• If the site is a scam using the brand of a real bank, you risk identity theft, loss of funds, or being lured into a bogus “investment” deposit scheme.

My conclusion on legitimacy:
Based on available data, the entity “Iowa State Bank” appears to be a genuine U.S. community bank with a legitimate website. However, I cannot conclusively verify that the domain iowastate.bank is fully operational in all jurisdictions or that deposits from overseas (e.g., Nigeria) would be treated with the same protection as U.S. residents. Because you flagged suspicion and because the risk to you (across jurisdictions) is elevated, I would treat the site with caution and not consider it safe for international deposit or investment without further due diligence (e.g., confirm with regulators, speak directly to bank via verified phone, confirm deposit insurance).
If you were a U.S. resident in Iowa and used the bank locally, the risk appears lower. But from your vantage point abroad: high caution is warranted. Thus: legitimate bank brand, questionable suitability for your use case. Not obviously a scam, but not fully safe given your context.
