What to do if…
you notice unexplained micro-deposits in your account that you did not request
Short answer
Call your bank’s fraud or electronic-transfers team using a trusted number and ask them to block unauthorized account-linking and watch for (or stop) any related withdrawals.
Do not do these things
- Don’t “return” the money by sending a transfer to anyone who contacts you about it.
- Don’t share the deposit amounts with anyone except your bank — scammers sometimes need those amounts to finish linking your account.
- Don’t click links or call numbers from messages that claim to explain the deposits.
- Don’t assume it’s safe because it’s under $1 — micro-deposits are often used for account verification before bigger activity.
- Don’t ignore it until you see a withdrawal; moving fast is what prevents escalation.
What to do now
- Document what you’re seeing: screenshot or write down each micro-deposit amount, date/time, and the description/company name (you may see descriptors such as “ACCTVERIFY” or a company name you don’t recognize).
- Scan for paired activity: look for any small debits that match/offset the credits, and check for any new scheduled payments, external transfers, or newly linked accounts.
- Call your bank using a trusted route (now): use the number on your debit card or your bank’s official app/website. Ask for the fraud team or ACH/electronic transfers team.
- Use clear words that trigger the right internal process: say, “I have unauthorized micro-deposits and I’m concerned someone is trying to verify/link my account. I need my account protected and any unauthorized electronic transfer activity blocked.”
- Ask the bank for protections that fit your account type: options vary by bank and by consumer vs. business accounts, so ask what they can do today, such as:
- Blocking or restricting new ACH debits/originators (sometimes called an ACH block/filter).
- Restricting external transfers or adding extra verification for new transfer recipients.
- Reviewing and removing linked external accounts or transfer profiles you don’t recognize.
- Issuing a new account number if they believe your account/routing details are exposed.
- Lock down access immediately after the call: change your online banking password, enable multi-factor authentication, remove unknown devices/sessions, and update your email password if it shares credentials or if you suspect phishing.
- Add a quick identity-protection layer if it doesn’t feel contained to your bank: place a credit freeze (or at minimum a fraud alert), then check your credit reports through the official channel for new accounts or inquiries you don’t recognize.
- Create an official record you can use later if needed: report at IdentityTheft.gov and save the recovery plan/report details. If your bank isn’t addressing clear unauthorized transfer risk appropriately, you can also submit a complaint to the CFPB.
What can wait
- You don’t need to determine who initiated the deposits today — your bank can investigate the origin.
- You don’t need to decide whether to permanently change banks right now.
- You don’t need to purchase paid identity monitoring immediately; focus first on bank controls and a freeze if needed.
Important reassurance
Micro-deposits often show up before major damage is done — which means spotting them now is useful. Acting quickly (bank fraud team + access lockdown + credit protection if needed) is a strong, practical response.
Scope note
This is first-step guidance to prevent escalation and preserve options. If your bank confirms unauthorized electronic transfers or identity theft, follow their dispute process and keep records, because deadlines and documentation can matter.
Important note
This guide is general information for immediate harm prevention, not legal advice. Bank procedures vary by institution and account type. If the issue involves consumer electronic fund transfers, ask your bank about Regulation E error-resolution and report promptly because time limits can apply.
