Not everyone can join every credit union, but most people can join at least one
Credit unions are not open to the general public the way banks are. Each credit union has a field of membership — a specific group of people allowed to join. This might be people who work for a particular employer, live in a certain county, belong to a specific organization, or share a common characteristic like working in healthcare or education. Some credit unions have broad fields of membership; others are very narrow.
The field of membership exists because credit unions are member-owned cooperatives, not profit-driven institutions. They set their own rules about who can join, and those rules are written into their charter. Before you can open an account or borrow money, you must meet the credit union's membership requirements.
If you do not meet one credit union's requirements, you may still meet another's. Many people may have access to for multiple credit unions and can choose which one to join based on services, fees, or convenience.
Key Takeaways
- Each credit union sets its own membership rules, called a field of membership, which may be based on your employer, location, profession, or membership in an organization.
- You cannot open an account at a credit union unless you meet its membership requirements, though you can often join a different credit union if one rejects you.
- Some credit unions allow family members of existing members to join even if they do not personally meet the field of membership requirement.
- Membership is usually free or costs a small one-time fee, and you must maintain a minimum deposit to keep your account open.
- The National Credit Union Administration (NCUA) publishes a directory where you can search for credit unions by location or employer to see if you may have access to.
Common fields of membership and who they cover
The most common field of membership is employer-based. If you work for a company, government agency, school district, or nonprofit, that employer may have a credit union. Employees — and sometimes retirees and their families — can join. For example, a city government might have a credit union for all municipal employees, or a hospital system might have one for its staff.
Geographic fields of membership cover everyone who lives or works in a specific area: a county, city, or region. These tend to be larger credit unions because they serve a broader population. If you live in the service area, you can join regardless of your job or background.
Association-based membership ties the credit union to a professional group, trade, or organization. Teachers, nurses, military members, farmers, and members of specific unions often have credit unions available to them. You must be a member of the associated group to join the credit union.
Some credit unions use multiple fields of membership, meaning they serve several different groups at once. A credit union might accept employees of three specific companies plus anyone living in two adjacent counties. The credit union's website or membership process will list all the groups it serves.
How to learn about you can join a specific credit union
The simplest way to check is to visit the credit union's website and look for a membership or "Who can join" page. Most credit unions clearly state their field of membership there. If the information is not obvious, call the credit union directly — staff can tell you in minutes whether you meet their requirements.
You can also search the NCUA Credit Union Locator at mapping.ncua.gov. Enter your location or employer name to see which federally insured credit unions serve your area or workplace. The locator shows each credit union's field of membership, so you can see exactly who qualifies.
If you work for a large employer, check your employee benefits materials or intranet. Many employers list their credit union as an employee benefit, and the materials explain how to join. Your HR or payroll department can also point you to the right credit union.
Family members and expanded membership rules
Many credit unions allow family members of existing members to join even if the family member does not personally meet the field of membership. For example, if your spouse works for an employer with a credit union, you may be able to join as their family member. The definition of "family" varies — some credit unions include spouses and children, others include parents and siblings, and some have broader definitions.
A few credit unions have community charter provisions that allow them to accept members who do not fit the primary field of membership, as long as those members make up a small percentage of the total membership. This gives credit unions some flexibility to serve people in their area who would otherwise be excluded.
Always ask the credit union directly about family membership or community provisions. The rules differ significantly from one credit union to another, and staff can tell you whether an exception applies to your situation.
What happens after you meet membership requirements
Meeting the field of membership is the first step, but it is not the only requirement. Credit unions will still check your banking history, credit report, and identity before opening an account. They use these checks to assess risk and prevent fraud — the same way banks do.
You will also need to maintain a minimum deposit to keep your membership active. This is usually a small amount, often $5 to $25, held in a savings account. As long as you keep that balance, your membership stays open. If your account falls below the minimum, the credit union may close it and end your membership.
Some credit unions charge a one-time membership fee, though many do not. If there is a fee, it is typically $5 to $10. The credit union will disclose this fee before you open an account.
What to do if you do not meet any credit union's membership requirements
If you have searched and cannot find a credit union that accepts you, you have other options. Banks offer many of the same services as credit unions — checking and savings accounts, loans, and debit cards. Some online banks have lower fees and higher interest rates on savings than traditional banks, though they do not have the membership structure of credit unions.
You can also check whether you may have access to for a credit union through a family member, organization membership, or geographic area you may have overlooked. Many people discover they may have access to for a credit union through a spouse's employer, a professional association they belong to, or a county they used to live in but still have ties to.
If your situation changes — you get a new job, move to a different area, or join an organization — you may become may be able to access for a credit union later. It is worth checking again periodically if credit union membership matters to you.
Frequently Asked Questions
Can I join a credit union if I am retired?
Many credit unions allow retirees to join if they were members while employed, or if they worked for an employer that sponsors a credit union. Some credit unions also accept retirees as family members of current employees. Check with the specific credit union about its retiree policy.
What if I move to a different state?
If you move, you may no longer meet a geographic field of membership, but you can usually keep your account open if you were already a member. Some credit unions also allow members to stay even after they move away. Check your credit union's policy on out-of-state membership before you relocate.
Can I join a credit union through my spouse's employer?
Many credit unions allow spouses of employees to join as family members. Some require the employee to be an active member first, while others let spouses join independently. Contact the credit union to ask about family membership rules.
Do I have to stay a member if I no longer meet the membership requirement?
This depends on the credit union's rules. Some allow you to keep your account even if you no longer meet the original requirement, while others require you to maintain membership status. Ask your credit union what happens if your circumstances change.
How do I know which credit union to join if I may have access to for more than one?
Compare the credit unions on fees, interest rates, branch locations, online banking features, and customer service. You can join more than one credit union if you meet multiple membership requirements, though most people choose one based on which offers the best services for their needs.
