Mobile and Digital Experience

Just about any banking you might do at a branch office can also be done digitally through online and mobile banking. You can use these platforms to review information about your accounts at GreenState and other financial institutions, make loan payments, review cashed checks, transfer funds, pay bills — even do your taxes.

You can join GreenState by calling 800-397-3790, visiting a branch or filling out an online application online.

GreenState Credit Union Fees

Because credit unions are nonprofit and member-owned, they aim to keep fees low. You’ll pay $5 to join. After that, you can avoid fees by minding your balance and keeping your accounts open and active. Here are fees you might encounter at GreenState Credit Union:

Type Amount
Credit union membership fee $5
Monthly maintenance fees $0
Overdraft and non-sufficient funds $29.50 for the first two each year and $34 for each subsequent overdraft, plus $29 per month if account is overdrawn for 30 days or more

GreenState Credit Union vs. Competitors

People who live, work or attend school in Iowa have several credit unions to choose from. You can compare these credit unions to GreenState to make sure you select the financial institution that best fits your needs.

Credit Union Best For
GreenState Credit Union Outstanding rates on premium checking accounts for members who use their debit cards frequently
Veridian Credit Union Competitive rates on home and auto loans
Dupaco Community Credit Union Live video tellers and shared branches to expand personal service
Collins Community Credit Union Range of account types, including Coverdell education savings and health savings accounts

GreenState Credit Union vs. Veridian Credit Union

Veridian has excellent rates on home and auto loans. Recent promotions include a 2.69% annual percentage rate on auto loans for 2019 and newer model years, and a 3.10% APR for a 5-year fixed home equity line of credit. But GreenState gets the nod when it comes to high checking account interest — as long as you make enough debit card transactions to earn the preferred rates.

GreenState Credit Union vs. Dupaco Community Credit Union

Dupaco offers live video tellers who work remotely, including after regular branch hours. That’s a huge benefit for members who like to bank face-to-face, but not for those who are fine making the same transactions at an ATM. For these members, GreenState has a much larger network of ATMs you can use surcharge-free.

GreenState Credit Union vs. Collins Community Credit Union

Collins Community Credit Union has an excellent range of savings products, along with checking account interest rates that beat GreenState’s premium rates for balances of $15,000 or less. However, membership at Collins Community is restricted to a much smaller area than GreenState covers.

Final Take

GreenState Credit Union offers competitive rates on a comprehensive range of products. Although its customer service availability can’t rival that of larger financial institutions, members can still detailed information on products and services on the credit union’s website.

    Rewards checking offers rates are high enough to make you wonder why you need a separate savings account. The caveat is that you must use your debit card frequently — otherwise, the rates drop through the floor.
