How to join a credit union
Joining a credit union usually takes one visit or one phone call, and most credit unions let you open an account with $25 to $100. You will need a government ID, proof of address (a utility bill or lease works), and your Social Security number. Some credit unions let you start the process online; others require you to come in person or mail documents. The whole thing typically takes a few days to a week.
The main barrier is membership itself — you have to meet the credit union's field of membership before you can join. This might mean you work for a specific employer, live in a certain county, belong to a particular organization, or have a family member who already belongs. Once you confirm you meet that requirement, the account opening is straightforward.

Check if you meet the field of membership requirement
Before you apply, confirm that you actually may have access to to join. Credit unions are not open to everyone — they serve specific groups. The most common membership paths are living in a defined geographic area (a county or city), working for a particular employer or industry, or being related to someone who already belongs.
Visit the credit union's website and look for "membership requirements" or "who can join." If you are not sure, call the credit union directly and ask. They can tell you in one minute whether you meet the requirement. If you do not, they may be able to refer you to a credit union that serves your situation, or they may have a workaround — some credit unions let you join through a community organization or by making a small donation to a nonprofit.
Gather the documents you will need
Have these items ready before you contact the credit union or visit in person:
- A government-issued photo ID (driver's license, passport, or state ID card)
- Proof of your current address (a utility bill, lease, mortgage statement, or bank statement dated within the last 60 days)
- Your Social Security number
- Your employer name and address (if the credit union asks for employment verification)
Some credit unions may ask for additional information depending on the account type you want to open. If you are opening a business account or applying for a loan at the same time, they may request tax returns or other financial documents. Call ahead and ask what they need so you do not make a wasted trip.
Choose between online, in-person, or mail application
Many credit unions now offer online account opening, which is the fastest route. You upload photos of your ID and proof of address, enter your information, and the credit union reviews it within one to three business days. Some credit unions still require you to visit a branch in person to verify your identity and sign documents. A few accept mailed applications, though this is slower — expect one to two weeks for processing.
Check the credit union's website to see which methods they offer. If you have a choice, online is usually fastest. If you are uncomfortable uploading documents online or the credit union does not offer it, an in-person visit is the next best option. You will meet a staff member, they will verify your ID on the spot, and you can ask questions about accounts and services while you are there.
Make your initial deposit
Credit unions require a minimum deposit to open an account, usually between $25 and $100. This becomes your first deposit into a savings or checking account. You can bring cash, a check, or arrange a transfer from another bank. Some credit unions waive the minimum deposit if you set up a direct deposit from your paycheck.
Ask the credit union which account type they recommend for your situation. If you want to borrow money later, they may suggest opening a savings account first to build a relationship and history with them. If you just want a place to keep money, a basic checking or savings account works fine.
Understand what membership means
When you open an account, you become a member-owner of the credit union. This is different from a bank customer. As a member, you have voting rights on major decisions the credit union makes, and you share in any profits the credit union earns — usually through better interest rates on savings and lower fees on loans.
You do not have to do anything special to be a member beyond maintaining your account. You can use all the credit union's services: checking, savings, loans, credit cards, and financial advice. If you close your account, your membership ends, though you can rejoin later if you still meet the field of membership requirement.
What happens after your account opens
Once your account is approved, the credit union will give you access to your account online or through their mobile app, usually within one business day. You will receive a debit card and checks in the mail within one to two weeks. If you need to withdraw money immediately, you can visit a branch and request a temporary card or withdrawal.
After your account is open, you can apply for other products — a credit card, a loan, or a certificate of deposit. Credit unions often give better rates to members who have had an account for a few months, so do not rush into borrowing. Use your account for a while, build a history, and then explore loans or credit products when you need them.
Frequently Asked Questions
Can I join a credit union if I do not live in the service area?
It depends on the credit union. Some serve only a specific county or city. Others serve multiple states or have a broader membership category — for example, "anyone who works in healthcare" or "anyone related to a current member." Call the credit union and ask if they have a membership path for you, or ask if they can refer you to one that does.
What if I do not have a proof of address?
If you do not have a utility bill or lease, bring other documents that show your current address: a bank statement, mortgage statement, insurance policy, or government mail. Some credit unions accept a letter from a shelter, employer, or government agency confirming your address. Call ahead and ask what they will accept.
Can I open an account online if I do not have a scanner or camera?
Yes. If the credit union offers online opening but you cannot upload documents, call them and ask about mailing or in-person options. You can also visit a branch in person and open an account on the spot — no scanner needed. Many credit unions have staff available during evening and weekend hours.
How long does it take to get my debit card and checks?
Debit cards and checks usually arrive within one to two weeks. If you need money right away, visit a branch and ask for a temporary card or a withdrawal. You can also set up online transfers to move money to another account while you wait for your card.
Do I have to keep a minimum balance in my account?
It varies by credit union and account type. Some accounts have no minimum balance requirement; others require $25 or $100 to stay open. Ask the credit union about the specific account you are opening. If the minimum is too high, they may have a different account type that works better for you.
