Compliance with FDA 21 CFR Part 11 for Electronic Records

Compliance with FDA 21 CFR Part 11 for Electronic Records

The Food and Drug Administration (FDA) has established regulations to ensure that electronic records and signatures are accurate, reliable, and trustworthy in industries such as pharmaceuticals, medical devices, and food processing. These regulations are outlined in 21 CFR Part 11, which is also known as the Electronic Record/Signature Rule. Compliance with these regulations is mandatory for companies operating within FDA-regulated industries.

What is 21 CFR Part 11?

21 CFR Part 11 is a regulation that establishes guidelines for electronic records and signatures. The regulation aims to ensure that electronic data is reliable, accurate, and trustworthy, while also allowing companies to take advantage of the benefits of electronic documentation. The regulation applies to all FDA-regulated industries, including pharmaceuticals, medical devices, food processing, and animal feed.

Key Components of 21 CFR Part 11

The following are key components of 21 CFR Part 11:

  • Electronic Records: Electronic records must be accurate, complete, and reliable.

  • Electronic Signatures: Electronic signatures must be unique to the signer and must not be repudiable (i.e., a signature cannot be denied).

  • Authentication: Electronic records and signatures must be authenticated to ensure their integrity.

  • Security: Electronic records and signatures must be secure from unauthorized access or tampering.


    • Detailed Requirements for Electronic Records

    Electronic records under 21 CFR Part 11 must meet the following requirements:

  • Accurate and Complete: Electronic records must be accurate, complete, and reliable. They must be generated and maintained by an automated system that is designed to produce accurate results.

  • Authorized Signatures: Electronic signatures on electronic records must be authorized by the person signing them. This means that the person signing must have a valid password or other authentication method to access the system.

  • Authentication: Electronic records and signatures must be authenticated to ensure their integrity. This can be done through various methods, such as digital certificates or encryption.


    • Some key points about electronic records under 21 CFR Part 11 include:

    Audit Trails: An audit trail is a record of all changes made to an electronic record. It must be maintained for a period of at least 6 months and must be readily available for inspection.
    Record Formats: Electronic records can be stored in various formats, such as PDF or XML. However, the format used must be documented and must not compromise the integrity of the record.

    Some key points about electronic signatures under 21 CFR Part 11 include:

    Unique Signatures: Electronic signatures must be unique to the signer and must not be repudiable.
    Authentication Methods: Various authentication methods can be used, such as digital certificates or encryption.
    Validating Signatures: Electronic signatures must be validated to ensure they are authentic.

    Detailed Requirements for Electronic Signatures

    Electronic signatures under 21 CFR Part 11 must meet the following requirements:

  • Unique Signatures: Electronic signatures must be unique to the signer and must not be repudiable.

  • Authentication Methods: Various authentication methods can be used, such as digital certificates or encryption.

  • Validating Signatures: Electronic signatures must be validated to ensure they are authentic.


    • Some key points about electronic signatures under 21 CFR Part 11 include:

    Unique Identifiers: Unique identifiers, such as a digital certificate, must be used to authenticate the signers identity.
    Authentication Methods: Various authentication methods can be used, such as biometric or password-based authentication.
    Signature Validation: Electronic signatures must be validated to ensure they are authentic and have not been tampered with.

    Implementation of 21 CFR Part 11

    Implementing 21 CFR Part 11 requires a thorough understanding of the regulations requirements. The following steps can be taken to implement the regulation:

    1. Conduct a Risk Assessment: Conduct a risk assessment to identify potential risks associated with electronic records and signatures.
