Find a Credit Union

The NCUA has a locator tool that shows credit unions based on your location. You can narrow your search to specific types of credit unions or search by the services offered. Each search result has an option to view more details. Here you can visit the credit union’s website to explore membership requirements, account options and locations.

Doing web searches for credit unions is another option to finding a credit union. You can try looking for options that serve specific groups or areas, or where membership is open to all. You could also ask people in your network where they’re members and whether they recommend their institutions. Just research the credit union carefully and read reviews before joining.

Pros and Cons of Credit Unions

When you do your banking through large credit unions, you may have advantages over choosing traditional banks and some smaller credit unions. While these perks can make large credit unions appealing, there are also potential drawbacks.

Pros of Credit Unions

• Extensive Banking Services: Like big banks, large credit unions can serve as a single destination for depositing, borrowing and investing money. You’ll often find a wide array account and credit options in addition to financial planning services and insurance products.
• More Competitive Fees and Rates: Since credit unions don’t focus on profits, members often get lower bank account fees and interest rates on credit products. Plus, these financial institutions tend to pay a more competitive annual percentage yield (APY) on interest-bearing deposit accounts than banks – again because of its not-for-profit status.
• Larger Number of Branch and ATM Locations: Compared to credit unions serving smaller areas, the biggest ones often cover several cities and sometimes even have branches overseas. Plus, many have thousands of fee-free ATMs.
• Member Education and Support: Because most credit unions are community based, they are known for offering a personalized customer experience you might not find at big banks. This is less of an advantage of the largest nationwide credit unions, but large credit unions often also include many financial education resources to help members.

Cons of Credit Unions

• Requirements for Membership: While some open membership to anybody, other large credit unions require that you or an immediate family member has some eligible association. Depending on your situation, you might find it easier to qualify for membership at a smaller credit union in your community.
• Potentially Fewer Business Banking Options: While many large credit unions offer several business products, some have a small selection or focus only on personal banking.
• Limited Locations: Large credit unions often only serve specific cities or states, and they usually have fewer branches than big banks. You might find that the biggest credit unions don’t have branches where you live.

The Bottom Line

Whether you’re interested in savings accounts, low-cost loans or investment services, picking one of the biggest credit unions may very well be the best choice for your banking needs. Just make sure you meet the membership requirements and can get competitive rates and low fees. And unless you choose an online-only credit union, you should check for convenient branches for the best experience.
