The Code of Federal Regulations (CFR) Part 11, also known as 21 CFR Part 11, is a set of regulations issued by the United States Food and Drug Administration (FDA) that outlines the requirements for electronic records and electronic signatures in the pharmaceutical, biotechnology, and medical device industries. These regulations, which were first introduced in 1997, aim to ensure the integrity, authenticity, and reliability of electronic data and signatures used in these industries.
Overview of 21 CFR Part 11

21 CFR Part 11 applies to all electronic records and electronic signatures that are created, modified, maintained, archived, retrieved, or transmitted under any records requirement set forth in agency regulations. This includes, but is not limited to, electronic records related to the manufacture, testing, and distribution of pharmaceuticals, biologics, and medical devices. The regulations require that electronic records be trustworthy, reliable, and equivalent to paper records, and that electronic signatures be secure and authentic.
Key Requirements of 21 CFR Part 11
The key requirements of 21 CFR Part 11 can be summarized as follows:
- Validation: Electronic systems must be validated to ensure that they are functioning as intended and that they produce accurate and reliable results.
- Security: Electronic systems must be secure to prevent unauthorized access, use, or alteration of electronic records and signatures.
- Electronic Signatures: Electronic signatures must be secure, authentic, and equivalent to handwritten signatures.
- Electronic Records: Electronic records must be trustworthy, reliable, and equivalent to paper records.
- Audit Trails: Electronic systems must maintain audit trails to track all changes, additions, or deletions to electronic records.
- System Administration: Electronic systems must have controls in place to ensure that system administration is properly managed, including user authorization, access controls, and system maintenance.
