The Best Local Credit Unions in the St. Louis Metro
Revised July 13, 2026
What are the best credit unions in the St. Louis area?
The St. Louis metro has strong member-owned credit unions on both sides of the river. St. Louis–headquartered options include First Community (the largest, about $4.78 billion in assets), Together (formerly the Anheuser-Busch Employees’ Credit Union), Vantage, Neighbors, Alliance, West Community, Alltru, and the community-focused St. Louis Community Credit Union; Scott and 1st MidAmerica anchor the Illinois Metro East. Most now let anyone who lives or works in the area join, and members typically get better loan and savings rates than at a bank.

Maybe a neighbor in Florissant just financed a car and mentioned the rate she got through her credit union, and it was a full point lower than what your big bank quoted. You start to wonder if you’ve been leaving money on the table for years.
If that sounds familiar, you’re in one of the best metros in the country to do something about it. St. Louis — on both sides of the river — is thick with strong, member-owned credit unions, several of them founded right here for local workers and neighborhoods. This guide walks through the best local credit unions across the metro, who’s allowed to join each one, and why so many St. Louisans quietly bank this way.
What Makes a Credit Union Different From a Bank
The short version: a credit union is a not-for-profit financial cooperative that’s owned by its members, not by outside shareholders. When you open an account, you become a part-owner with a vote. Because there are no stockholders to pay, the money a credit union earns flows back to members as lower loan rates, higher savings rates, and fewer fees. A bank, by contrast, answers to investors who expect a profit.
That difference shows up in real numbers. According to the National Credit Union Administration (NCUA), the federal regulator, credit unions nationally averaged a 6.27% rate on a 60-month new-car loan versus 7.50% at banks, and paid 3.26% on a one-year $10,000 CD versus 2.41% at banks (NCUA, 2025). On a car loan or a mortgage, a point or more adds up to real money over the life of the loan.
And your money is just as safe. Deposits at federally insured credit unions are protected up to $250,000 by the NCUA — the credit-union equivalent of FDIC insurance, backed by the full faith and credit of the U.S. government. The coverage amount is identical to a bank’s; only the insuring agency’s name changes.
The St. Louis–Headquartered Credit Unions
These are the home-grown institutions — founded and headquartered in the St. Louis area, most now open to anyone who lives or works in the metro.
First Community Credit Union (Chesterfield) is the largest credit union headquartered in St. Louis — roughly $4.78 billion in assets, more than 408,000 members, and about 42 branches. It celebrated its 90th anniversary in 2024, and its community charter covers St. Louis City plus a wide sweep of Missouri and Illinois counties, so most metro residents can join.
Together Credit Union (St. Louis) began in 1939 as the Anheuser-Busch Employees’ Credit Union — a beer-industry credit union that grew into a roughly $2.64-billion institution with about 145,000 members and 26 branches. It rebranded to Together in 2020 and is now a founding and official banking partner of St. Louis CITY SC. Membership is open to people who live or work across the core metro counties, plus employees of partners like Anheuser-Busch, Nestlé Purina, and BJC, and their families.
Vantage Credit Union (Bridgeton) runs about 14 metro branches and has one of the friendliest community charters around: you can join if you live, work, worship, or attend school in St. Louis, St. Charles, Jefferson, or Franklin counties in Missouri, or St. Clair or Madison counties in Illinois.
Neighbors Credit Union (St. Louis), with about 8 branches, leans on a “once a member, always a member” promise and serves the core Missouri and Illinois metro counties, plus select employer groups like Costco and Bi-State/Metro.
Alliance Credit Union (Fenton) was founded in 1948 and carries deep labor-union and skilled-trades roots — its field of membership includes dozens of employer groups and several labor organizations alongside the usual live-or-work-here counties on both sides of the river.
A Metro That Keeps Growing: Recent Mergers
The St. Louis credit-union map has shifted recently, and it’s worth knowing so you don’t go looking for a branch that’s changed its sign.
West Community Credit Union (O’Fallon, MO) completed a legal merger with Gateway Metro Federal Credit Union on April 7, 2026, creating a roughly $670-million credit union with 43,000-plus members and about 16 branches under the West Community name. Alltru Credit Union (Wentzville) is another rebrand to know: it was 1st Financial Federal Credit Union until late 2020, and it started life in 1968 as the McDonnell Douglas Credit Union — a nod to St. Louis’s aerospace heritage. Alltru is a certified Community Development Financial Institution (CDFI) serving St. Louis City, St. Louis County, and St. Charles County.
And there’s a big new entrant: CommunityAmerica Credit Union, Missouri’s largest credit union at roughly $5 billion in assets, planted its flag in St. Louis by merging in Electro Savings Credit Union on January 1, 2025. It now runs branches in Maryland Heights, Manchester, South County, and St. Peters, with membership eligibility inherited from Electro’s metro charter.
The Metro East (Illinois) Anchors
Don’t forget the Illinois side — the Metro East has its own strong, locally rooted credit unions.
Scott Credit Union (Edwardsville) is the Metro East’s largest home-grown credit union, with roots at Scott Air Force Base and a field of membership spanning more than 30 Illinois and Missouri counties; a $5 minimum share opens the door. 1st MidAmerica Credit Union (Bethalto) serves around 64,000 members across some 21 Illinois counties from about 10 branches, and recently expanded into Granite City through a local merger. Both are excellent options if you live or work on the Illinois side of the river — and both reflect our whole-metro reality that “local” in St. Louis stretches well into Illinois.
A St. Louis Story Worth Telling: St. Louis Community Credit Union
If you want a credit union that doubles as a force for the neighborhoods, St. Louis Community Credit Union is the standout. With about $427 million in assets and more than 51,000 members across 14 branches, it’s the region’s largest CDFI and one of the nation’s larger Minority Depository Institutions — meaning it deliberately banks underserved parts of North City and North County that big banks have long overlooked.
The impact is concrete: more than $40 million in business loans, roughly 90% of them to Black-owned businesses, plus payday-loan alternatives and its “Sure Rides” affordable auto-loan program. It even reopened a historic Gateway branch honoring one of the nation’s first African American–owned banks. For a lot of St. Louisans, joining here is as much a vote for the community as it is a smart financial move.
How to Choose — and How Membership Works
The old idea that you need a special connection to join a credit union is mostly history. Every credit union has a “field of membership” — the rules for who can join — but most of the St. Louis institutions above now hold a community charter, which typically means anyone who lives, works, worships, or attends school in a given county is eligible. In practice, nearly every metro resident qualifies for several of these.
To choose, start with what you actually do at a bank. Want branches near your home and work? Compare locations. Carry a car loan or plan to buy a house? Compare loan rates. Keep a big savings balance? Compare CD and savings rates. Also ask whether the credit union participates in the CO-OP shared-branching and ATM network, which lets members use thousands of other credit unions’ branches and surcharge-free ATMs nationwide — a quiet perk that makes a local credit union feel a lot bigger than its branch count. Opening an account usually takes a small deposit (often $5 to $25) that represents your ownership share.
Are There Any Downsides?
To be fair, credit unions aren’t perfect for everyone. Because membership is tied to a field of membership, you have to be eligible to join — though, as noted, most metro residents qualify for several. A single local credit union also has fewer branches than a national megabank, so if you travel constantly or move out of state, that can matter (the CO-OP shared-branch network softens this a lot). And historically, some smaller credit unions lagged big banks on app features and digital tools, though most St. Louis institutions have closed that gap and now offer solid mobile banking, Zelle, and online account opening.
The honest takeaway: for the vast majority of St. Louisans — anyone who wants better loan and savings rates, lower fees, and a say in how their institution is run — the tradeoffs are minor next to the upside. It’s worth pulling up two or three of the credit unions above, comparing their rates and branch maps against your current bank, and seeing for yourself what a switch would save you.

What is the hardest credit union to get into?
In today’s St. Louis metro, almost none are truly hard to join. Most local credit unions now hold a community charter, so anyone who lives, works, worships, or attends school in a covered county is eligible. A few still lean on employer or labor-union groups, like Alliance’s trades roots, but most residents qualify somewhere easily.
How safe is it to keep $500,000 in a credit union?
Very safe, if you structure it right. The NCUA insures up to $250,000 per depositor, per credit union, per ownership category. To fully cover $500,000, spread it across different ownership categories — individual, joint, retirement — or across two credit unions. Every dollar within those limits is backed by the U.S. government.

Almost anyone can. Most St. Louis credit unions now hold a community charter, meaning anyone who lives, works, worships, or attends school in a covered county can join — and between them they cover the entire metro on both sides of the river. Opening an account usually requires a small share deposit, often $5 to $25.
Do credit unions have better interest rates than banks?
Generally, yes. Because credit unions are not-for-profit and member-owned, they tend to pay more on deposits and charge less on loans. NCUA figures for 2025 show credit unions averaging 6.27% on a 60-month new-car loan versus 7.50% at banks, and 3.26% versus 2.41% on a one-year $10,000 CD.
