How to Identify an Unknown Interac e-Transfer Sender

To identify an unknown Interac e-Transfer sender, first confirm in your bank or credit union’s own app that money was actually deposited. Then record the sender name, amount, date, status, and Interac reference from the legitimate notification and compare them with expected invoices, customers, tenants, or other payment records. If the match is still unclear, confirm with the likely sender through a contact method you already trust or ask your financial institution to investigate.

Do not click an unexpected message, classify the deposit as income, apply it to an invoice, or send it back until you have verified what happened. An unfamiliar payer can be a customer using a different banking name, someone paying on another person’s behalf, an honest mistake, or a fraudulent notification.

What Can an e-Transfer Notification Tell You About the Sender?

Interac says a legitimate email notification contains the sender’s full legal name and uses notify@payments.interac.ca in the email field. The message may also show the amount, date, status, optional note, and a unique reference number.

Those details are useful identifiers, but they do not always reveal the business relationship. A banking name may belong to:

• A company owner paying a supplier invoice personally
• A tenant’s roommate, spouse, parent, employer, or support agency
• An employee paying for a company purchase
• A customer whose legal name differs from the name on the invoice
• A bookkeeper or property manager sending on behalf of someone else

The displayed name is therefore a lead, not permission to guess. Interac also warns that an unexpected notification should be confirmed with the sender through another channel.

What Should You Record Before Investigating?

Create an unmatched entry without assigning income, rent, or another category yet. Preserve:

• Amount
• Notification date and bank-deposit date
• Sender’s displayed full name
• Email address or mobile number shown, when available
• Sent or received direction
• Status, such as deposited or pending
• Interac reference number
• Destination bank account and connected inbox
• Optional message or memo
• Possible customer, invoice, property, tenant, or purpose
• Evidence checked and follow-up still required

Interac says every e-Transfer receives a unique reference number used to identify and track that individual transfer. Keep it private and use it to distinguish payments with the same sender, amount, or date. Do not treat it as an invoice number.

If the reference itself is what you need to locate or reconcile, use the Interac e-Transfer reference-number guide to find it, group lifecycle messages, and match it to the bank record.

How Do You Match an Unknown e-Transfer Safely?

1. Verify the deposit outside the email

Open the financial institution through its known app or website. Confirm the amount, account, date, and final status in the transaction history.

Email and text carry notifications; financial institutions move the money. A realistic-looking message with no matching bank deposit may be phishing. If the transfer is pending, declined, cancelled, or expired, keep it out of completed-payment totals and use the e-Transfer status reconciliation workflow.

2. Preserve the legitimate notification and reference

Check the sending address and the sender name shown in the message. Save the notification with the bank evidence instead of copying only the amount into a spreadsheet.

If anything looks suspicious, do not respond, deposit through an email link, disclose a security answer, or forward the reference number to an unknown person. Interac advises contacting a purported sender through another channel and forwarding suspected phishing notifications to its phishing address.

3. Compare the payment with expected amounts

Review the records that show what you expected to collect:

• Open and recently paid customer invoices
• Partial balances and instalment schedules
• Rent rolls and tenant balances
• Customer-deposit agreements
• Refunds, reimbursements, or supplier credits
• Transfers expected from an owner, partner, employee, or related business

Match on several facts, not amount alone. Use the payer name, date, amount, reference, expected balance, project, property, and message together.

For client invoices, the freelancer payment workflow explains how to keep the payment register separate from accounts receivable. For rent, use the rent e-Transfer reconciliation guide.

4. Search the full notification history

Search the relevant inboxes by the displayed name, amount, date, and reference. A reminder, Autodeposit confirmation, or later status message may provide context missing from the first result.

Count the transaction once. Several emails can describe one transfer. If you are rebuilding an older period across accounts or inboxes, follow the historical e-Transfer recovery process.

5. Confirm through a trusted channel

Contact the likely customer, tenant, or other party using a phone number, email thread, client portal, lease record, or contact already on file. Do not use new contact information supplied only by the unexpected message.

Ask for enough non-sensitive detail to confirm the match: the amount, approximate send date, invoice or rental period, and who sent on whose behalf. Do not ask the person to send passwords, security answers, full banking details, or identity numbers.

Record who confirmed the payment, when, and what it applies to.

6. Apply it only after the purpose is known

Once the match is supported, update the correct record:

• Apply a customer payment to the identified invoice.
• Apply rent to the correct tenant, unit, and rental period.
• Record a customer deposit separately from an earned sale.
• Classify an owner contribution separately from customer income.
• Link a reimbursement or refund to the original transaction.

If the amount is only a partial payment, leave the remaining balance open. If one transfer covers several obligations, preserve the original amount and document allocations that add back to it.

7. Escalate an unresolved or disputed deposit

Interac says it does not hold or trace account funds and directs transaction issues to the participating financial institution. Contact the bank or credit union through a trusted number, website, branch, or in-app support when the payer cannot be identified, the records conflict, or fraud is suspected.

Keep the item unmatched while it is investigated. Do not send money to a person who contacts you unexpectedly and claims the deposit was a mistake. Ask the financial institution how to handle the transaction safely.

How Should an Unknown Deposit Appear in Business Records?

Do not label an unexplained deposit as sales merely to clear the bank reconciliation. The Canada Revenue Agency says business income records must identify the date, amount, and source and be supported by original documents. It also warns that without records showing income sources, a business may be unable to demonstrate that some amounts are non-business or non-taxable.

Use a temporary unmatched-payment or suspense category according to your bookkeeping process, keep the full evidence, and resolve it promptly. Once the source and purpose are known, move it to the correct customer, rent, owner, refund, loan, or other account. Ask a qualified bookkeeper or accountant how to present a material unresolved amount at a reporting date.

What Edge Cases Need Extra Care?

Autodeposit completed before you recognized the sender

Autodeposit can put the funds in the registered account automatically. You still need to confirm the deposit and business purpose. Do not assume an automatically deposited amount is customer income.

Someone paid on behalf of a customer or tenant

Keep both the displayed payer and the person whose balance was credited. Add the confirmation and relationship instead of changing the transfer record to make the names match.

The message is a Request Money notification

Confirm the direction before acting. A request asks you to send money; it is not evidence that someone paid you. Open the known banking app and check whether funds entered or would leave the account.

The amount matches several invoices

Leave it unmatched until another fact distinguishes the payment. A rounded amount or common monthly rent is not enough by itself.

How TransferLog Helps Match Unknown Notifications

TransferLog organizes details found in supported Interac e-Transfer notification emails from connected Gmail, Outlook, or iCloud inboxes. You can search and filter by names, dates, amounts, directions, statuses, references, categories, and connected inbox, then export CSV or PDF on the Pro plan.

Use it to bring the notification clues into one reviewable list, assign an unmatched category, and find related messages. Then confirm the deposit in the bank account and match it to invoices, rent rolls, agreements, and trusted contacts.

TransferLog does not identify a person beyond the details in the notification, access bank accounts, trace funds, verify identity, decide whether a message is genuine, or return a mistaken payment.
