The online banking platform (online.nbc.ca) is fully bilingual.

Does National Bank have 24-hour customer service?

No. National Bank's phone lines operate during business hours (approximately Mon–Fri 8 AM–8 PM ET; Sat 8 AM–5 PM ET). Emergency card services (lost/stolen card) may be available outside these hours — call the number on the back of your card. For after-hours account issues, the National Bank mobile app allows card freezing at any time without calling.

How do I find a National Bank branch?

Use the Branch and ATM Locator at nbc.ca/en/personal/ways-to-connect/branches-atms.html. National Bank has 375+ branches in Canada, concentrated in Quebec. In Ontario, branches are primarily in Ottawa, Toronto, and other major cities. Western Canada and Atlantic Canada have very limited coverage — a handful of locations in major urban centres only.

How do I report a lost or stolen National Bank card?

Call the number on the back of your National Bank debit or credit card immediately. You can also freeze your card in the National Bank mobile app (app → Card Management → Freeze card) while you locate it or arrange a replacement. Report fraud to the fraud line at 1-877-394-6683. When reporting a lost card by phone, have your account number and recent transactions ready to verify your identity.

How do I escalate a complaint with National Bank?

First contact National Bank customer service by phone or through the online complaint form at nbc.ca. If unresolved within the bank, escalate to the National Bank Client Complaint Appeals Office (CCAO). If still unresolved after the CCAO process, escalate externally to the Ombudsman for Banking Services and Investments (OBSI) at obsi.ca. National Bank is a federally chartered bank and OBSI member — OBSI provides free, independent dispute resolution for banking and investment complaints.
