Verified NAB phone numbers
| Channel | Number | Hours | Region | |
|---|---|---|---|---|
| NAB personal | 13 22 65 | Mon–Sun 24h | Australia |
National Australia Bank Limited operates one of the largest bank customer-service operations in the country. The main consumer line 13 22 65 routes through an automated menu first — to reach a human agent quickly, press 0 repeatedly or say 'agent' when prompted. Wait times are typically shortest mid-week between 9am and 11am local time, longest on Monday mornings and the day after a service outage or product launch.
NAB segments specialist teams behind the main number: billing, technical support, account security, and an executive escalation desk reachable only after Tier 1 has logged the case. The brand publishes its contact details at https://www.nab.com.au/about-us/contact-us; the page is updated periodically with new toll-free numbers, regional offices, and country-specific lines for international customers. Always verify the number on that page before dialing — scam operators routinely buy ads on the brand's name and substitute their own number to harvest payment details.
If NAB cannot resolve your case after two contacts, the regulator for this category is Australian Financial Complaints Authority (https://www.afca.org.au/). A regulator complaint forces a written response within 30 days and is the single most effective consumer tool in this market.

⚠️ Scam advisory
NAB impersonation scams are common in AU. Warning signs: (1) caller asks for your password, full card number, PIN, or one-time passcode; (2) tells you a 'fraudulent' transaction or login happened and pressures you to act in minutes; (3) asks you to install remote-access software like AnyDesk or TeamViewer; (4) demands payment in gift cards or cryptocurrency. If any of these happen — hang up. Then dial 13 22 65 yourself (never call back a number the caller gave you) to verify there is no real issue. Report the scam to https://www.afca.org.au/ and to NAB's abuse address listed on https://www.nab.com.au/about-us/contact-us.
