Trial deposits usually take one to three business days to show up in your bank account after the platform sends them.1Federal Reserve Financial Services. Innovation Spotlight Microdeposits The exact timing depends on when the request was submitted, your bank’s processing schedule, and whether a weekend or federal holiday falls in between.
Why the Wait Is One to Three Business Days
Traditional ACH transfers move in batches during business hours. The ACH network settles payments several times per business day, but the Federal Reserve’s settlement system is closed on weekends and federal holidays. Submit a linking request on a Friday afternoon and processing won’t begin until Monday morning, with the deposits often not posting until Tuesday or Wednesday.
Requests made early on a weekday morning tend to arrive faster than those submitted late in the day. The speed also depends on when your bank processes incoming ACH credits after the originating platform submits its batch.
The small test transfers themselves exist for a reason: Nacha, the organization that governs the ACH network, requires platforms originating certain electronic debits to validate the account as part of their fraud-detection process before processing transactions.2Nacha.

When Trial Deposits Can Arrive Instantly
The Federal Reserve’s FedNow Service operates around the clock, every day of the year, including weekends and holidays.3Federal Reserve Board. FedNow Service Platforms and banks that support FedNow can send and settle micro-deposits instantly rather than waiting for the traditional one-to-three-day ACH window, which cuts out the weekend and holiday delay entirely.1Federal Reserve Financial Services. Innovation Spotlight Microdeposits
Not every bank and platform has adopted FedNow yet, so instant micro-deposits aren’t universally available. If neither side of the transfer supports it, you’re back to the standard ACH timeline.
What to Do If the Deposits Don’t Show Up
If three business days have passed and you don’t see the deposits, work through a few common causes before contacting anyone.
Check that you picked the right account type when you set up the link. Selecting checking when the account is savings, or the reverse, can cause the transfer to fail silently. Then confirm your routing number and account number are correct down to the digit. A single wrong digit will send the deposits somewhere else or get the transfer rejected outright.
Look carefully at your transaction history. Some banks group small ACH credits or display them under short reference codes that don’t obviously match the platform’s name. Check both posted and pending transactions, because micro-deposits may sit as pending before they finish posting.
If your details are right and the deposits still haven’t appeared, contact both the requesting platform’s support team and your bank. The platform can confirm the deposits were actually sent, and the bank can check whether any incoming ACH credits were rejected or held.
How Long You Have to Enter the Amounts
Once the deposits do land, you don’t have unlimited time to finish the linking. Many platforms set a window, often around ten days, for you to enter the amounts after they were sent. Miss the deadline and the verification request expires, so you’ll have to start over with a fresh set of deposits. Check the platform’s instructions for its specific timeframe.
When you do enter the amounts, record them down to the penny. Most platforms allow only one or two additional tries after an incorrect entry before requiring you to restart the process, and some lock the verification feature temporarily after repeated failures as a fraud-prevention measure.
Deposits You Didn’t Ask For
Legitimate micro-deposits only arrive after you personally entered your bank details into a platform. If small deposits appear that you didn’t initiate, treat them as a warning sign that someone may be trying to link your account to their platform, and contact your bank. Real companies also don’t send emails or texts with links asking you to verify deposit amounts; go directly to the platform’s app or website if you need to enter them.4Consumer Advice.
