Is it safe to share {X} with {Y}?
No. Passport numbers are government-issued identity credentials, and entering them into ChatGPT introduces real risk of unintended data retention and exposure. OpenAI's default settings allow conversation data to be retained for up to 30 days and reviewed by staff for safety and model improvement purposes. There is no mechanism within standard ChatGPT usage that restricts how this data is stored, processed, or accessed after submission.
Why this matters
- ChatGPT is not a secure document processing environment, meaning passport numbers entered into prompts are treated as general text with no special handling or access controls.
- Retained conversation data can be reviewed by OpenAI personnel, creating a pathway for sensitive identity information to move beyond the user's control.
- Passport numbers are high-value identifiers used in identity verification systems, making accidental exposure disproportionately damaging compared to most personal data types.
For enterprise
Employees who enter passport numbers into ChatGPT outside of approved internal systems may be in direct violation of data handling policies, particularly those governed by GDPR, CCPA, or sector-specific compliance frameworks. Organizations processing passport data are typically bound by strict purpose limitation rules, and using a third-party AI tool as a processing environment almost certainly falls outside permitted use. Security and compliance teams should treat this as a policy gap requiring explicit guidance.

What counts as Passport Numbers?
- Passport numbers
- Government-issued identification numbers
- National identity numbers
- Driver's license numbers
- Tax identification numbers
Why people share Passport Numbers with ChatGPT
- To draft messages using real names or personal details
- To understand user data quickly
- To summarize profiles or records
- To prepare reports based on user information
What actually happens when you paste Passport Numbers into ChatGPT
When you paste Passport Numbers into ChatGPT, that data is transmitted from your device to external servers operated by the AI provider.
Depending on system configuration and policies, the data may be logged, temporarily stored, or reviewed for safety and quality purposes. Retention can last from days to weeks, and in some cases may extend beyond the immediate session.
Statements such as “we do not train on your data” do not eliminate risks related to retention, logging, or internal access. These controls vary by product and setting, and are not always visible to end users.
From a governance perspective, any non-zero retention window introduces exposure risk when sensitive data is shared without controls, auditability, or enforcement.
Risks of sharing Passport Numbers with ChatGPT
- Identity theft: Exposed personal details can be used to impersonate individuals across services.
- Phishing attacks: Leaked contact information enables targeted phishing campaigns.
- Account takeover: Identifiers can be used to reset passwords and gain access to accounts.
Is this allowed under policy or law?
Safer ways to handle Passport Numbers
Passport Numbers should not be shared with consumer AI tools without controls in place. If AI assistance is required, organizations should use systems that enforce data redaction, access controls, and policy enforcement before data leaves their environment.
- Automatically redact sensitive fields before sending data to AI models
- Prevent unauthorized data from being entered into external tools
- Maintain audit logs and visibility into how data is used
- Ensure compliance with frameworks like GDPR, CCPA, and SOC 2
Platforms like Wald are designed to enable safe AI usage by ensuring sensitive data never leaves your control unprotected.
