You can transfer money from one credit union to another in three main ways: an ACH transfer through your online banking, a wire transfer, or an in-person transaction at a shared branch. ACH is usually free and takes one to three business days. A wire arrives the same day but costs roughly $10 to $30. Shared branching lets you walk into a participating credit union and move money at the counter.
What You Need Before You Start
Every transfer method depends on the same basic information from the receiving credit union: the nine-digit routing number, the account number, and whether the account is checking or savings. The routing number sits at the bottom left of a check from that account and usually appears in the mobile app or online banking under account details.1American Bankers Association. Routing Number Policy and Procedures
Many credit unions require that the names on both accounts match. Sending money directly to someone else’s account through your online portal may not be possible without extra steps, so check your credit union’s rules before you assume it will work.
Linking the Other Credit Union Account
Before you can send money electronically, most credit unions require you to link the external account. Look in your online banking or mobile app for a tab called “External Transfers” or “Link an Account.” You enter the routing number, account number, and account type, and the credit union verifies that you actually own the other account.
Verification usually uses micro-deposits. The credit union sends two small deposits, each under a dollar, to the external account within one or two business days. You log back in, enter the exact amounts, and the link becomes active. Some credit unions use instant verification through a third-party service and skip the micro-deposit step.
ACH Transfers: The Default Choice
The Automated Clearing House network is how most credit unions move money between institutions electronically. ACH groups transfer requests into batches and processes them at set intervals during the business day instead of sending each one individually.2Federal Reserve Board. Automated Clearinghouse Services
A standard ACH transfer takes one to three business days. Once your external account is linked, you pick the amount, choose a one-time or recurring transfer, and submit. The request moves through the ACH network on the next batch cycle.
Same-Day ACH
If one to three days is too slow, same-day ACH is available for transfers up to $1 million per transaction.3Federal Reserve Services. Same Day ACH Resource Center The Federal Reserve processes same-day files in three windows each business day, with submission deadlines at 10:30 a.m., 2:45 p.m., and 4:45 p.m. Eastern Time. Not every credit union offers same-day ACH for external transfers, so ask yours directly if speed matters.
Wire Transfers for Same-Day Delivery
Wires send money individually and in real time rather than in batches. Most domestic wires move through the Fedwire Funds Service: the sending credit union transmits a secure electronic message to the receiving institution, and the funds settle immediately.4Federal Reserve Board of Governors. Fedwire Funds Services Once a wire is processed, it is final. You cannot reverse it.
Your credit union sets its own cutoff for accepting wire requests, usually midafternoon. Miss the cutoff and the wire goes out the next business day. Wires work best for large or time-sensitive transfers where you need confirmation that the money arrived the same day. For anything that can wait, ACH is cheaper.
Shared Branching
The CO-OP Shared Branching network lets you walk into a participating credit union that is not your own and transact as if you were at your home branch. The network includes over 5,600 locations nationwide. Bring three things: your credit union’s name, your account number, and a photo ID.5SharedBranching.org. Access Your Credit Union Account at Thousands of Locations Nationwide
The teller pulls up your account through a shared system and processes deposits, withdrawals, and transfers. A few limits apply: transactions generally have to happen in the lobby rather than the drive-thru, wires are not available through shared branching, and withdrawal caps vary by host location. Standard shared branching services are free to members, though the host may charge for extras like official checks or money orders.6SharedBranching.org. Frequently Asked Questions – Shared Branching
What Each Method Costs
- Standard ACH transfers to and from a linked external account are usually free at credit unions.
- Outgoing domestic wires generally run $10 to $30. Incoming wires are often free or carry a smaller fee. Check your credit union’s fee schedule before sending.
- Standard shared branching transactions are free to members.
For a routine transfer that can wait a few business days, ACH is the obvious choice. A wire is worth the fee when the money has to arrive the same day.
When the Money Becomes Available
Federal law caps how long a credit union can hold incoming funds. Under the Expedited Funds Availability Act, money received by wire must be available for withdrawal no later than the next business day.7Office of the Law Revision Counsel. 12 US Code 4002 – Expedited Funds Availability Schedules The same next-business-day floor applies to electronic payments, including ACH credits.8eCFR. 12 CFR 229.10 – Next-Day Availability
Many credit unions release ACH funds the same day they arrive, but the law only requires next-business-day availability. Business days exclude weekends and Federal Reserve holidays, so a transfer initiated Friday afternoon may not be available until Tuesday if Monday is a holiday. A receiving credit union can also place a temporary hold if it has reason to question a transfer’s validity, releasing the full balance once the hold period under its disclosed policy expires.
Reporting Rules for Large Transfers
Federal law requires credit unions to report certain transactions. Any transaction involving more than $10,000 in currency triggers a Currency Transaction Report filed with the Financial Crimes Enforcement Network.9eCFR. 31 CFR 1010.311 – Filing Obligations for Reports of Transactions in Currency The filing is automatic and routine. It does not mean anyone suspects you of anything.
What does cause problems is deliberately splitting a large transaction into smaller ones to stay under the threshold. That is called structuring, and it is a federal crime regardless of whether the underlying money is clean.10Office of the Law Revision Counsel. 31 US Code 5324 – Structuring Transactions to Evade Reporting Requirement Prohibited If you need to move $15,000, move $15,000 in one transfer. Do not break it into three $5,000 pieces across different days.
Separately, for electronic transfers of $3,000 or more, financial institutions must collect and keep records about the sender and receiver under the Bank Secrecy Act’s recordkeeping and travel rules.11Federal Register. Threshold for the Requirement to Collect, Retain, and Transmit Information on Funds Transfers Your credit union handles that paperwork.
If a Transfer Goes Wrong
Regulation E gives you 60 days from the date of the statement showing the problem to report an unauthorized or incorrect electronic transfer. Once you report it, the credit union must investigate within 10 business days and tell you the results within three business days of finishing. If it needs more time, it can extend the investigation to 45 days, but it has to provisionally credit your account within 10 business days while it keeps looking.12eCFR. 12 CFR 1005.11 – Procedures for Resolving Errors
If your debit card or account credentials are lost or stolen and someone starts moving money, how fast you report it sets your maximum liability:
- Report within two business days of learning about the loss, and your liability is capped at $50.
- Report after two business days but within 60 days of your statement, and liability can reach $500.
- Report after 60 days from the statement, and you could be on the hook for the full amount of any unauthorized transfers made after that 60-day window, with no cap.13eCFR. 12 CFR 205.6 – Liability of Consumer for Unauthorized Transfers
Review your statements. Call the credit union the moment something looks wrong instead of waiting for the next cycle.
