Business Proof of Address for Desjardins or National Bank: The Guide
Desjardins and National Bank require a recent business proof of address signed by an identifiable third party, a document Ancre generates on demand as a bilingual PDF.
To get a business proof of address accepted by Desjardins or National Bank, you generally need a recent, clearly dated document signed by an identifiable third party confirming the company genuinely receives mail at the declared address, a document Ancre generates on demand as a bilingual PDF, ready to attach to any application. Quebec banks won't settle for a lease or a bill in an individual's name: they want confirmation tied directly to the company itself.
That level of scrutiny often surprises founders opening their first business account, especially those used to lighter, faster requirements for an everyday personal account at the same branch. A bank opening a business account takes on a real verification responsibility, particularly under anti-money-laundering and know-your-customer rules, which is why a verbal claim or a form with no supporting document usually isn't enough on its own.
What Desjardins and National Bank actually ask for
Both institutions typically ask for the articles of incorporation or registration with the business registry, government-issued ID for each of the authorized signatories, and proof that the declared address is functional. That last piece can take the form of a commercial lease, but a lease isn't always available, especially for a company that just incorporated or that operates from a registered address rather than a directly rented space. That's exactly where a registered-office attestation becomes useful: it confirms, on letterhead with the operator's verifiable contact details, that the company's mail genuinely arrives at that address.
One detail that comes up often: the proof of address must match the address declared with the business registry exactly, box number included. A slight difference in wording, an omitted box number, or a different abbreviation, can be enough for a cautious bank analyst to reject a file, delaying account opening by days or weeks.
How Ancre's attestation works
Once an Ancre box is open, an address attestation can be generated on demand from the dashboard, in French or English, with the issue date, the full address including the box number, and Kebek IA's contact details for verification. This document works directly for opening a Desjardins or National Bank account, but also for a business credit card application, a commercial insurance file, or a check requested by a corporate client before signing a first contract.
Some institutions ask for a notarized version of the proof of address for particular files, an option available a la carte rather than included in the base plans, precisely because it only applies to a minority of cases. For the vast majority of account openings, the standard attestation, generated in seconds, fully satisfies the institution's request.
Avoiding back-and-forth with your bank advisor
The best way to avoid a rejection or a request for an extra document is to prepare the attestation before the bank appointment, rather than generating it in a rush after a first refusal. As with anything tied to the business registry, Ancre supplies the document but doesn't replace a bank advisor or accountant for questions specific to the account structure chosen, the authorized signatories, or the banking services needed for a given industry.
The same document also works elsewhere: RBC, Stripe, PayPal, and Square all ask for a similar proof of address before activating a merchant account or processing a first payout to a business account. A commercial insurer often requests it before issuing a policy, and a supplier requiring a security deposit typically accepts it in place of an on-site visit to confirm the company actually exists somewhere. Keeping this attestation current and easy to find in the dashboard avoids having to regenerate it in a rush every time a new institution asks for it.
Documents generated from the Ancre dashboard are timestamped and hosted on servers located in Canada, which also indirectly satisfies the confidentiality requirements some financial institutions apply to documentation received from their business clients. A company that switches plans keeps the same document history, with no need to re-request an attestation already issued under a previous plan.
