AKO Help Desk Number

Legacy AKO Help Desk Contact

The Army Knowledge Online help desk was historically reached at 1-866-335-2769, also expressed as 1-866-335-ARMY.

AKO has been retired, so this legacy number may no longer provide support for current Army services. Personnel should use the support channel shown within the specific Army system they are attempting to access or contact their organization’s information-management or service-desk staff.

Before Requesting Help

• Confirm that the website address belongs to an official .mil domain.
• Verify that the Common Access Card is inserted and that its certificates are available to the browser.
• Close and reopen the browser, then retry the sign-in.
• Test another supported browser or government-managed workstation.
• Record the exact error message, affected service, and time of the failure.

Information to Provide

When contacting a support desk, be prepared to provide your name, organization, duty location, callback information, affected system, and a concise description of the problem. Include an existing ticket number when following up.

Do not disclose passwords, PINs, authentication codes, recovery codes, or other secrets. Legitimate support personnel should not ask for your CAC PIN or account password.

Common Access Problems

CAC or Certificate Errors

Check that the card reader detects the CAC and select the appropriate authentication certificate. Expired certificates, outdated middleware, or incorrect computer time can prevent authentication.

Account Lockout

Repeated failed sign-in attempts may lock an account. Stop retrying and use the affected service’s official recovery process or support desk.

Website Unavailable

If an official Army site will not load, verify the address, network connection, and browser configuration. Government services may require a managed device, approved network, or VPN.
