How to join a credit union
To join a credit union, you need to meet the membership requirements set by that specific union, then complete a membership application. Most credit unions require you to live, work, or worship in a certain geographic area, or belong to a particular employer or organization. Once you meet the membership requirement, you fill out an application (usually online or in person), provide identification and proof of address, and often make a small deposit to open a share account — typically $5 to $25. The whole process usually takes a few days to a week.
The key difference from joining a bank is that credit unions are member-owned cooperatives, so membership is a prerequisite to having an account. You cannot simply walk in and open a checking account the way you can at a bank. But the membership itself costs nothing beyond that initial deposit, and membership gives you voting rights on how the credit union operates.
Key Takeaways
- Credit unions limit membership to people who meet specific criteria — usually based on where you live, where you work, or an organization you belong to.
- You will need a government-issued ID, proof of your address, and usually a Social Security number to complete a membership application.
- Most credit unions require an opening deposit of $5 to $25 to establish your share account, which is your membership stake in the union.
- You can find credit unions that match your membership criteria by searching the CO-OP Network or Allpoint directories, or by asking your employer or community organization.
- Once you join, you become a partial owner of the credit union and can vote on major decisions, unlike bank customers who have no ownership stake.
Understanding membership requirements
Every credit union sets its own membership rules, called a field of membership. This field defines who can join. Common membership criteria include living in a specific county or city, working for a particular employer or industry, attending a certain school or religious organization, or being related to someone who already belongs to the union.
Some credit unions have very broad fields of membership — for example, "anyone who lives or works in the five-county metro area" — while others are narrow, such as "employees of XYZ Manufacturing and their families." A few large credit unions, like Connexus or Pentagon Federal, have fields of membership that span entire states or regions.
Before you start an application, check the credit union's website or call their membership department to confirm you meet their requirements. If you do not, they will not process your application, no matter how complete it is. If you are unsure whether you may have access to, ask directly — membership staff can usually tell you in one phone call.
What documents and information you will need
Credit unions are required by federal law to verify your identity and address before opening an account. Bring or upload a government-issued photo ID (driver's license, passport, or state ID card) and a recent document showing your current address, such as a utility bill, lease, or bank statement dated within the last 60 days.
You will also need your Social Security number. The credit union uses this to run a background check and to report your account activity to credit bureaus. Have your employer name and address ready if the credit union's membership field is based on employment. If you are joining through a family member, have their name and account number available.
Some credit unions now allow you to upload these documents through their website during the online application process. Others require you to visit a branch in person or mail copies. Check the credit union's website to see which method they accept.
The application process and timeline
Most credit unions offer online applications that take 10 to 15 minutes to complete. You will enter your personal information, confirm you meet the membership requirements, and upload or provide your ID and address proof. Some unions still require you to apply in person at a branch or by mail, so check their website first.
After you submit your application, the credit union reviews it to confirm your identity and membership status. This usually takes one to three business days. If everything checks out, they will approve your membership and ask you to make your opening deposit. You can often do this online by linking a bank account, or in person at a branch.
Once your deposit clears — typically one to five business days — your share account is active and you become a member. At that point, you can open a checking account, savings account, or apply for credit products like loans or credit cards. Some credit unions allow you to open these accounts during the membership application itself, while others require you to complete membership first.
Finding a credit union you can join
Start by asking your employer whether they sponsor a credit union. Many large employers, government agencies, and school districts have employee credit unions with low fees and competitive rates. If your employer does not, ask whether you work in an industry that has a credit union — for example, teachers often have access to education-focused credit unions.
Check whether you belong to any organizations — religious congregations, unions, professional associations, alumni groups — that sponsor a credit union. Some of these have been around for decades and offer strong rates to members.
If none of those apply, search the CO-OP Network directory or the Allpoint network on the Credit Union National Association website. These directories let you filter by state and membership criteria to find unions that accept people in your situation. You can also search "credit unions near me" and call local branches to ask about their membership requirements.
Opening your first accounts after joining
Once your membership is active, you can open a share savings account (the credit union equivalent of a savings account) and a share draft account (the equivalent of a checking account). Some credit unions combine these into one account; others keep them separate. The credit union will explain their account structure when you join.
Many credit unions offer their first account holders promotional rates or fee waivers for the first few months. Ask about these when you join. You will also want to set up direct deposit if your employer offers it — most credit unions waive monthly fees if you have direct deposit, and you may earn higher interest on savings accounts that way.
After you have held a savings account for a few months, you can usually apply for a credit card or loan. Credit unions often offer better rates than banks, especially if you have limited credit history. Your membership status and account history with the union will factor into their lending decisions.
What happens if you do not meet a credit union's membership requirements
If you do not meet a credit union's field of membership, you cannot join that specific union. However, you have other options. You may be able to join a different credit union that has a broader membership field. You can also look for credit unions that accept "community charter" members — people who do not meet the primary membership criteria but pay a small additional fee to join.
Some credit unions allow you to join if you open an account with a family member who already meets the membership requirements. This is called "family membership" and varies by union, so ask whether it is available.
If no credit union in your area will accept you, online credit unions and banks may offer similar products at competitive rates. Credit unions are not the only option for lower fees and better rates — they are simply one choice among several.
Frequently Asked Questions
Do I have to stay a member forever?
No. You can close your accounts and leave a credit union at any time. There is no contract or penalty for leaving. If you have a loan, you will need to pay it off or transfer it before you close your membership, but savings and checking accounts can be closed immediately.
What if I move and no longer meet the membership requirement?
Most credit unions allow you to keep your membership even if you move outside their field of membership, as long as you were a member in good standing when you moved. You can continue using your accounts and applying for loans. However, you may lose access to in-person branches. Check with your credit union about their policy on this.
Can I join multiple credit unions?
Yes. There is no rule against joining more than one credit union if you meet the membership requirements for each. Some people maintain accounts at multiple unions to take advantage of different products or rates. However, you will need to manage multiple logins and accounts, so most people stick with one.
Is there a membership fee?
No. Credit union membership itself is free. You only need to make an opening deposit to establish your share account, which is typically $5 to $25. Some credit unions charge monthly maintenance fees on checking accounts, but many waive these if you set up direct deposit or maintain a minimum balance.
How long does membership approval take?
Most credit unions approve membership applications within one to three business days, as long as your documents are complete and you meet the membership requirements. Once approved, your share account opens after your deposit clears, which usually takes another one to five business days. The entire process from application to active membership typically takes one to two weeks.
