Understanding Credit Unions and Their Basic Structure

A credit union is a financial institution owned and controlled by its members. Unlike banks, which are typically owned by shareholders, credit unions operate as not-for-profit organizations. This fundamental difference shapes how credit unions work and the services they offer to members.

Credit unions have existed in the United States since the early 1900s, with the first one established in New Hampshire in 1909. Today, there are approximately 4,900 credit unions operating across the country, serving about 130 million members. These institutions range in size from small community-based organizations with a few hundred members to large national networks with millions of members.

The structure of a credit union involves a board of directors elected by members. This board makes decisions about how the institution operates and how profits are distributed. Because credit unions are member-owned, any earnings beyond operational costs are typically returned to members through lower fees, better interest rates, or improved services. This contrasts with traditional banks, where profits go to shareholders.

Credit unions must be federally or state chartered and regulated. Federal credit unions are overseen by the National Credit Union Administration (NCUA), while state-chartered credit unions may be regulated by state banking authorities or the NCUA, depending on whether they hold federal insurance. This regulatory framework ensures that credit unions maintain financial safety and stability.

Membership in a credit union typically requires meeting certain criteria. These criteria vary by institution and might relate to geographic location, employment with a specific organization, membership in a particular group, or other factors. For example, some credit unions serve employees of certain companies, members of labor unions, residents of specific geographic areas, or people who work in particular professions.

Practical Takeaway: Before exploring membership options, understanding that credit unions operate differently from banks helps you see why they may offer different pricing structures and services. Their not-for-profit status means potential advantages in fees and rates, but specific offerings depend on each individual credit union's decisions and policies.

How to Find and Evaluate Credit Unions in Your Area

Finding a credit union that matches your needs involves several research steps. The NCUA maintains a public database of all federally insured credit unions, which is searchable by state, city, or zip code. This resource allows you to see which credit unions operate in your area and what membership criteria they have.

When searching for credit unions, you'll encounter different types based on their membership structure. Community credit unions serve people who live or work in a specific geographic area. Occupational credit unions serve people employed in particular industries or professions—for example, teachers' credit unions, healthcare worker credit unions, or government employee credit unions. Group credit unions serve members of specific organizations or associations. Family credit unions allow members to add family members even if they don't meet the original membership criteria.

Location is one consideration, but not the primary factor anymore. Many credit unions offer online banking, mobile apps, and phone-based services that reduce the importance of having a branch nearby. Some credit unions participate in shared branching networks, allowing members to conduct transactions at other credit unions' locations. The CO-OP Network, for example, includes more than 30,000 ATMs and thousands of shared branching locations nationwide, providing members of participating credit unions with widespread access to services.

When evaluating credit unions, consider several factors beyond location. Look at the types of accounts they offer—checking, savings, money market, and certificate of deposit (CD) accounts. Review the interest rates they pay on savings accounts and CDs. Check what fees they charge for various services like overdrafts, ATM use outside their network, or account maintenance. Some credit unions charge no monthly fees for basic checking accounts, while others may have fee structures similar to banks.

You should also examine what loan products the credit union offers. Credit unions typically provide personal loans, auto loans, mortgage loans, and credit cards. The interest rates on these products and any associated fees matter significantly if you plan to borrow. Some credit unions offer specialized loan products, such as debt consolidation loans or home equity lines of credit.

Practical Takeaway: Use the NCUA's online database to identify credit unions you may be able to join, then visit their websites to compare services, rates, and fees. Don't assume that a credit union must be physically near you—online services and shared branching networks mean you can effectively use a credit union from a distance.

Membership Requirements and How They Work

Credit union membership criteria exist because credit unions were originally designed to serve defined groups of people with shared characteristics or connections. Understanding these requirements helps you determine which institutions might be open to you. Membership rules cannot be arbitrary—they must be documented and applied consistently to all applicants.

Geographic-based membership is among the most straightforward criteria. These credit unions serve anyone who lives, works, or attends school in a specific area. For example, a community credit union might serve all residents of a particular county or metropolitan area. This approach makes membership widely available to people in that region. If you move outside the service area, some credit unions allow you to maintain membership while others may require you to close your account.

Occupational credit unions serve people in specific professions or industries. Teachers' credit unions, for instance, require members to be employed as educators or work in education-related roles. Similarly, credit unions exist for nurses, police officers, federal employees, military members, and dozens of other professions. Some occupational credit unions have been quite successful—the Navy Federal Credit Union, which serves active-duty military, retirees, and their families, is one of the largest credit unions in the country with millions of members.

Employer-sponsored credit unions serve employees of specific companies or government agencies. These are particularly common among large employers and government organizations. Membership is typically open to current employees and sometimes to their family members or retirees. Some employer credit unions have expanded their membership to allow family members of employees to join even if they don't work for the employer themselves.

Group-based membership criteria can relate to membership in associations, labor unions, religious organizations, or other groups. For example, some credit unions serve members of specific churches, alumni associations, or professional organizations. The membership criteria must be clearly defined and objective.

Once you determine that you meet a credit union's membership criteria, the next step typically involves opening a membership account. This generally requires providing personal identification, Social Security number, and other standard financial information. Some credit unions may conduct a background check or review your credit history, though this is not universal. A few credit unions may require an initial deposit to open a membership share account, though many have eliminated minimum deposits.

Practical Takeaway: Research the specific membership requirements of each credit union you're considering. Many people qualify for multiple credit unions through their job, residence, or group affiliations. You are not limited to joining just one—many people maintain memberships at two or three credit unions if they meet different membership criteria.

Services and Products Available Through Credit Unions

Credit unions offer a range of financial products and services comparable to those at traditional banks, often with different pricing structures. Understanding what's available helps you determine whether a credit union meets your financial needs.

Deposit accounts form the foundation of credit union services. These include share savings accounts (similar to bank savings accounts), share draft accounts (similar to checking accounts), money market accounts, and certificates of deposit. The terminology differs from banks—credit unions use "share" instead of "account" because members technically own a share of the credit union. Interest rates on savings products at credit unions vary, and in recent years have been competitive with or sometimes higher than rates at traditional banks. According to data from the Credit Union National Association, the average interest rate on credit union savings accounts has sometimes exceeded rates at traditional banks by meaningful amounts.

Lending products include personal loans, auto loans, mortgages, credit cards, and home equity lines of credit. Credit unions often promote lower interest rates on loans compared to traditional banks. For example, auto loan rates at credit unions are frequently one to two percentage points lower than rates at banks or captive finance companies. This difference adds up over the life of a loan—on a $20,000 auto loan, a one percentage point difference in interest rate amounts to hundreds of dollars in total interest paid.

Credit cards issued by credit unions tend to have lower annual percentage rates (APRs) than the industry average. According to Federal Reserve data, the average credit card APR across the industry has exceeded 20%, while credit union credit cards often have rates significantly lower. However, credit union credit cards may have fewer rewards programs or premium perks compared to cards offered by larger banks.

Many credit unions now offer services that rival those
