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 the default choice because most credit unions do not charge for it, though the money takes one to three business days to arrive. A wire costs roughly $10 to $30 and settles the same day. Shared branching lets you walk into a participating credit union that is not your own and move money at the counter.
What You Need Before You Start
Any transfer requires the receiving credit union’s nine-digit routing number, the account number, and the account type (checking or savings). The routing number appears at the bottom left of a check or in the account details of the credit union’s app or website.1American Bankers Association. Routing Number Policy and Procedures
Many credit unions also require that the name on both accounts match. Sending money directly to someone else’s account through your online banking may not be possible without extra steps, so if you are moving funds to another person, ask them how their credit union prefers to receive the transfer.
Linking the External Account
For an ACH transfer, you almost always need to link the other credit union’s account first. Look for a tab in your online banking called something like “External Transfers” or “Link an Account,” then enter the routing number, account number, and account type.
Most credit unions verify ownership using micro-deposits: two small amounts, usually under a dollar each, sent to the external account within one to two business days. You log back in, confirm the exact amounts, and the link is active. Some credit unions now offer instant verification through a third-party service, which skips the waiting period.
ACH Transfer: The Standard Option
The Automated Clearing House network moves money electronically in batches processed at set intervals throughout the business day.2Federal Reserve Board. Automated Clearinghouse Services A standard ACH transfer between credit unions takes one to three business days, and most credit unions do not charge for it.
After the external account is linked, you pick an amount, choose one-time or recurring, and submit. The request enters the next batch cycle and settles at the receiving credit union.
Same-Day ACH
If you need the money faster but do not want to pay wire fees, same-day ACH is an option at credit unions that offer it to members for external transfers. Same-day transactions can go up to $1 million each and are processed by the Federal Reserve in three windows, with submission deadlines at 10:30 a.m., 2:45 p.m., and 4:45 p.m. Eastern Time.3Federal Reserve Services. Same Day ACH Resource Center Not every credit union enables same-day ACH for consumer external transfers, so ask before you rely on it.
Wire Transfer: When You Need Same-Day Settlement
A wire sends money individually and in real time rather than in a batch. Most domestic wires between credit unions move through the Fedwire Funds Service: the sending institution transmits a secure message, and funds settle immediately at the receiving institution.4Federal Reserve Board of Governors. Fedwire Funds Services Once a wire is processed, it is final. It cannot be reversed.
Outgoing domestic wires typically cost between $10 and $30 at a credit union. Incoming wires are often free or carry a smaller fee. Your credit union’s cutoff for accepting wire requests is usually midafternoon, well before the Fedwire system itself closes at 7:00 p.m. Eastern.5Federal Reserve Banks. Fedwire Funds Service and National Settlement Service Operating Hours If you want the wire to go out today, call or visit your credit union early in the day.
Wires make sense for large or time-sensitive transfers where same-day arrival matters. For anything that can wait a day or two, ACH is cheaper.
Shared Branching: In-Person Between Credit Unions
The CO-OP Shared Branching network includes over 5,600 participating credit union locations nationwide. You can walk into a shared branch that is not your home credit union and conduct transactions as if you were at your own. You need three things: your credit union’s name, your account number, and a photo ID.6SharedBranching.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. Standard transactions are free, though the host branch may charge for extras like official checks or money orders. Wire transfers are not available through shared branching, and transactions generally must be done at the counter rather than the drive-thru.7SharedBranching.org.

When the Money Becomes Available
Federal law caps how long a receiving credit union can hold your incoming funds. Under the Expedited Funds Availability Act, wire transfers must be available for withdrawal no later than the next business day after receipt.8Office of the Law Revision Counsel. 12 US Code 4002 – Expedited Funds Availability Schedules The same next-business-day rule applies to ACH credits.9eCFR. 12 CFR 229.10 – Next-Day Availability
In practice, many credit unions release ACH funds the same day they arrive, but the law only guarantees next business day. Weekends and Federal Reserve holidays do not count as business days, so a Friday afternoon transfer may not be usable until Tuesday if Monday is a holiday. A credit union may also place a temporary hold if it needs to verify that the sending account has the funds.
Large Transfers and Reporting
Any transaction involving more than $10,000 in currency triggers a Currency Transaction Report that the credit union files with the Financial Crimes Enforcement Network.10eCFR. 31 CFR 1010.311 – Filing Obligations for Reports of Transactions in Currency This is automatic and routine. It does not imply suspicion.
What does cause trouble is splitting a large transaction into smaller pieces to stay under the $10,000 threshold. That practice, called structuring, is a federal crime whether or not the underlying money is legitimate.11Office 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 a single transfer.
If a Transfer Goes Wrong
Regulation E gives you 60 days from the date your credit union sends a statement showing the error to report an unauthorized or incorrect electronic transfer. Once you report it, the credit union has 10 business days to investigate and three business days after that to tell you the results. If it needs more time, it can extend the investigation up 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 a debit card or your account credentials are lost or stolen, how fast you report determines how much you can be on the hook for:
- Report within 2 business days of learning about the loss, and your liability is capped at $50.
- Report after 2 business days but within 60 days of your statement, and your liability can reach $500.
- Report after 60 days from your statement, and you can be responsible for the full amount of any unauthorized transfers that occur after that 60-day window, with no cap.13eCFR. 12 CFR 205.6 – Liability of Consumer for Unauthorized Transfers
Check your statements as they come in, and if you spot something wrong, call your credit union that day rather than waiting for the next cycle.
