What you need to join a credit union
Credit unions are membership organizations, not banks open to everyone. To join, you must meet the field of membership — a requirement set by each credit union that defines who can become a member. Common fields include working for a specific employer, living in a certain county, belonging to a particular profession or organization, or having a family member who is already a member. Some credit unions have broader fields that cover entire regions or industries.
Once you meet the membership requirement, joining is straightforward. You visit a branch or explore online, provide identification and proof of your membership qualification, and usually make a small deposit into a savings account — often between $5 and $25. This deposit becomes your share in the credit union and is what makes you a member-owner rather than just a customer.
The exact documents you need depend on which credit union you choose and what membership category applies to you. If you work for a covered employer, bring a recent pay stub or employee ID. If you live in the service area, bring a utility bill or lease showing your address. If you're joining through a family member, bring proof of your relationship.

Finding a credit union you can join
Start by checking whether you already may have access to for membership through your job, your address, or your family. If you work for a large employer, your company may sponsor a credit union — ask your HR department or check your employee benefits materials. If you live in a city or county, search for community credit unions that serve your area. If a family member belongs to a credit union, ask whether they can sponsor you as a household member.
The CO-OP Network locator (co-opnetwork.org) lets you search by location or employer and shows which credit unions serve your situation. Your state's credit union league website also lists all credit unions in your state and their membership requirements. Many credit unions publish their field of membership on their website under "Membership" or "Who Can Join."
If you don't when ready may have access to for any credit union, look for those with broader fields. Some credit unions serve entire states or regions, and some allow membership through organizations you may already belong to — religious congregations, alumni associations, professional groups, or community organizations. A few credit unions have fields open to anyone in the United States, though these are less common.
Documents to bring or submit
You will need a government-issued photo ID — a driver's license, passport, or state ID card. You will also need proof that you meet the membership requirement. The type of proof depends on your situation.
| Membership Path | Proof Documents |
|---|---|
| Employer-sponsored | Recent pay stub, employee ID badge, or letter from HR confirming employment |
| Geographic (county or city) | Utility bill, lease, mortgage statement, or government mail showing your current address |
| Family member | Birth certificate, marriage certificate, or adoption papers showing your relationship to the existing member |
| Organization or association | Membership card, dues receipt, or letter from the organization confirming your membership |
If you are explore online, you will upload images of these documents. If you are explore in person, bring the originals. Some credit unions accept documents by mail if you cannot visit a branch.
The membership process process
Most credit unions now offer online membership applications on their website. You fill out a form with your name, address, Social Security number, and employment or residency information. You upload your ID and proof of membership qualification. The credit union reviews your documents — this usually takes one to three business days — and contacts you if anything is missing or unclear.
Once approved, you choose your initial deposit amount and the type of account you want to open. Most people start with a savings account, though some credit unions let you open a checking account at the same time. You provide banking information if you want to fund the account by transfer, or you can mail a check, or visit a branch to deposit cash.
If the credit union does not offer online membership, you can explore in person at a branch or by mail. In-person applications are usually completed the same day. By-mail applications take longer because the credit union must receive your documents, verify them, and mail you confirmation and your account materials.
What happens after you join
Once your membership is active, you receive account numbers, a debit card (if you opened a checking account), and online banking access. You can use the credit union's ATM network and branch services when ready. If you joined through the CO-OP Network or Shared Branch network, you can also use other credit unions' ATMs and branches to conduct basic transactions.
As a member-owner, you have voting rights in credit union decisions and may receive dividends on your savings account if the credit union declares them. You also have access to the credit union's loan products, which often carry lower rates than banks because credit unions are nonprofit organizations that return earnings to members.
Your membership continues as long as you maintain at least one open account and keep the minimum balance — often just the initial share deposit. Some credit unions charge a small annual membership fee, though many do not. Check your credit union's fee schedule when you join.
Membership requirements that might disqualify you
Credit unions cannot deny membership based on race, color, religion, national origin, sex, marital status, age, or disability. However, they can deny membership if you do not meet the field of membership, if you have unpaid debts to another credit union, or if you have a history of fraud or serious financial misconduct. Some credit unions also run ChexSystems checks — a banking history report — and may deny membership if you have multiple closed accounts or unresolved disputes with other financial institutions.
If a credit union denies your membership, ask for the specific reason in writing. If you believe the denial was discriminatory, you can file a complaint with the National Credit Union Administration (NCUA) or your state's financial regulator. If the denial was based on ChexSystems, you have the right to see your report and dispute inaccurate information.
Frequently Asked Questions
Can I join a credit union if I don't work for the employer it serves?
No, not directly. However, you may be able to join if a family member works there, or if the credit union has a broader field of membership that includes your county or a community organization you belong to. Some employer-sponsored credit unions also allow membership through retirees or former employees of that company.
What if I don't meet any credit union's field of membership?
A small number of credit unions have fields open to anyone in the United States or a large multi-state region. You can search for these using the CO-OP Network locator. Alternatively, you might be able to join an organization or association that has its own credit union — some religious congregations, alumni groups, and professional associations sponsor credit unions with open membership for members.
Do I have to keep money in my savings account after I join?
You must maintain your initial share deposit to keep your membership active. This is usually $5 to $25. You can add more money to the account or leave it untouched — the credit union will not close your account as long as the share deposit remains. Some credit unions charge a fee if your balance falls below the minimum, so check the fee schedule.
How long does it take to become a member?
Online applications are usually approved within one to three business days. In-person applications at a branch are often completed the same day. By-mail applications take longer, typically one to two weeks, because documents must be mailed, reviewed, and returned to you.
Can I join multiple credit unions?
Yes. You can be a member of more than one credit union if you meet the membership requirements for each. Some people maintain accounts at both a credit union and a bank, or at multiple credit unions to access different services or loan products.
