In highly regulated industries like pharmaceuticals, biotechnology, and medical device manufacturing, data integrity isn't just a best practice; it's the law.
The U.S. Food and Drug Administration (FDA) established Title 21 of the Code of Federal Regulations (CFR) Part 11 to govern the use of electronic records and electronic signatures.
For any company looking to modernize its operations and move away from paper, understanding and complying with these regulations is non-negotiable.
Navigating the technical and procedural requirements of Part 11 can feel daunting. The stakes are high: non-compliance can lead to FDA 483 observations, warning letters, product delays, and significant financial penalties.
This guide breaks down the complexities of 21 CFR Part 11, providing a clear roadmap for ensuring your electronic signatures are trustworthy, reliable, and, most importantly, compliant.
Key Takeaways
- 📜 What is 21 CFR Part 11? It's the FDA's set of rules defining the criteria under which electronic records and signatures are considered as valid and trustworthy as their paper-and-ink counterparts.
- 🔗 Predicate Rules are Key: Part 11 applies when you use electronic systems to meet record-keeping requirements set by other FDA regulations (known as predicate rules). If the predicate rule requires a record, and you keep that record electronically, Part 11 kicks in.
- 🔐 Two Pillars of Compliance: Compliance rests on both technical controls (software features like audit trails, access controls, and signature standards) and procedural controls (internal policies, SOPs, and employee training).
- 🛡️ Signatures Must Be Secure: An electronic signature under Part 11 is more than just a name typed on a screen. It must be a unique, secure representation of an individual, linked to their actions, and just as legally binding as a handwritten signature.
- ✅ Validation is Mandatory: You must validate your electronic systems to prove they work as intended and meet all Part 11 requirements, ensuring the authenticity and integrity of your data.
What Exactly is 21 CFR Part 11?
Issued in 1997, 21 CFR Part 11 was the FDA's forward-thinking response to the growing use of computer systems in regulated research and manufacturing.
The regulation provides a legal framework to permit the use of electronic technology while ensuring the public health is protected. Essentially, it allows companies to benefit from the efficiency of digital workflows without sacrificing the integrity, authenticity, and confidentiality of their critical data.
The rule applies to electronic records that are created, modified, maintained, archived, retrieved, or transmitted under FDA predicate rules.
It also covers electronic signatures that are intended to be the legal equivalent of traditional handwritten signatures. This affects a wide range of companies, including:
- Pharmaceutical and biotechnology companies
- Medical device manufacturers
- Clinical research organizations (CROs)
- Food, beverage, and dietary supplement producers
- Cosmetics manufacturers
The Core Requirements: A Breakdown of Part 11 Controls
Compliance with 21 CFR Part 11 is achieved through a combination of system features and company procedures. These can be broadly categorized into technical and procedural controls.
Technical Controls: Building a Compliant System
These are the features and functions that must be built into the software you use for managing electronic records and signatures.
A compliant system, like The Ultimate Guide To Electronic Signatures, must provide robust security and traceability.
| Control Requirement | Description & Why It Matters |
|---|---|
| Closed System Validation | The system must be validated to ensure accuracy, reliability, and consistent intended performance. This proves to auditors that your system is fit for purpose. |
| Audit Trails | The system must generate a secure, computer-generated, time-stamped audit trail that independently records all actions related to creating, modifying, or deleting electronic records. This log must be unalterable and retained for as long as the underlying record. It's the digital equivalent of a lab notebook's permanent entries. |
| Access Controls | Access must be limited to authorized individuals. This involves unique user IDs and passwords, and potentially biometric or token-based authentication to ensure that only the right people can perform specific actions. |
| Electronic Signature Components | Signatures must contain the printed name of the signer, the date and time of signing, and the 'meaning' of the signature (e.g., review, approval, responsibility). |
| Signature & Record Linking | The electronic signature must be permanently linked to its corresponding electronic record to prevent any possibility of the signature being excised, copied, or otherwise transferred to falsify another record. |
Procedural Controls: Your Organizational Responsibilities
Technology alone isn't enough. Your organization must establish and enforce policies that govern the use of these systems.
- Standard Operating Procedures (SOPs): You need written policies for system use, maintenance, and security. This includes procedures for signature issuance, use, and revocation.
- Training: All personnel must be trained on their specific duties under Part 11. They must understand that their electronic signature is the legal equivalent of a handwritten one and that passwords must never be shared.
- System Documentation: You must maintain documentation for system validation, change control, and operational procedures, ready for FDA inspection.
- Certification to the FDA: Companies must formally certify to the FDA that they intend for the electronic signatures used in their systems to be the legally binding equivalent of traditional signatures.

Choosing the right e-signature provider is a critical step toward compliance. Not all solutions are created equal.
Use this checklist to evaluate potential vendors:
- ✅ Unique User Identification: Does the platform require a unique username and password for every user? Can it enforce strong password policies (e.g., complexity, periodic changes)?
- ✅ Secure, Time-Stamped Audit Trails: Does the system automatically capture every action (view, sign, modify, delete) with a non-editable timestamp, user ID, and action description?
- ✅ Signature Manifestation: Does the signature clearly display the signer's name, date/time, and the reason for signing as required?
- ✅ Record & Signature Linking: Can the vendor demonstrate that signatures are cryptographically bound to the document, ensuring they cannot be tampered with or moved?
- ✅ Validation Support: Does the vendor provide a validation package or comprehensive documentation to support your internal validation efforts? While you are ultimately responsible for validating the system in your environment, a good partner will make this process much easier.
- ✅ Robust Security Infrastructure: Is the platform built on a secure foundation? Look for certifications like SOC 2 Type II, ISO 27001, and HIPAA compliance, which demonstrate a commitment to security best practices. Wondering Are Electronic Signatures Secure To Use? These certifications are your answer.
- ✅ Accurate Record Copying: Can the system generate exact copies of records, both in human-readable (e.g., PDF) and electronic formats, for inspection or review?
eSignly was built with these requirements at its core, providing a secure, validated, and user-friendly platform that helps you meet and exceed FDA expectations.
2025 Update: Navigating Current FDA Trends in Enforcement
As technology evolves, so does the FDA's focus during inspections. In recent years, and looking ahead into 2025, there is an intensified focus on data integrity.
Inspectors are no longer just checking if you have an audit trail; they are scrutinizing the completeness and security of that trail. They are looking for evidence that data is protected from unauthorized alteration from the moment of its creation through its entire lifecycle.
Another key trend is the validation of cloud-based (SaaS) systems. The FDA fully accepts the use of cloud software, but the responsibility for validation remains with the regulated company.
This means it's more important than ever to partner with vendors like eSignly who provide robust security controls, transparent operations, and comprehensive validation support documentation. The expectation is that you can prove your cloud-based system is secure, validated, and under a state of control, just as you would an on-premises system.
Conclusion: Compliance is a Partnership
Achieving and maintaining 21 CFR Part 11 compliance is not a one-time project but an ongoing commitment to quality and data integrity.
It requires a deep understanding of the regulations, robust internal procedures, and powerful, purpose-built technology. While the regulations may seem complex, they provide a clear blueprint for ensuring that as you digitize your operations, you do so in a way that is secure, reliable, and trustworthy.

Frequently Asked Questions
What is a 'predicate rule' in the context of 21 CFR Part 11?
A predicate rule is any other FDA regulation that requires a company to create and maintain records. For example, Good Manufacturing Practice (GMP) regulations require batch records.
If a company decides to maintain these batch records electronically, the GMP rule is the 'predicate rule,' and the electronic system must then comply with 21 CFR Part 11.
Is a digital signature the same as an electronic signature under Part 11?
Not exactly, though they are related. An 'electronic signature' is the broad legal concept defined by Part 11 as the computer-based equivalent of a handwritten signature.
A 'digital signature' refers to a specific, cryptography-based technology used to secure a document and verify the signer's identity. Most compliant electronic signature solutions, including eSignly, use digital signature technology to meet the security and integrity requirements of Part 11.
Can I use a simple typed name as an electronic signature for Part 11?
No. A simple typed name does not meet the requirements. Part 11 requires the signature to be uniquely identifiable to the individual and securely linked to the record.
This is typically accomplished through a unique user ID and password combination, at a minimum, which must be entered at the time of signing to execute the signature.
Do we still need to validate software if it's from a 'Part 11 compliant' vendor?
Yes. A vendor can provide a 'Part 11 compliant tool,' but the regulated company is always responsible for validating the system for its specific, intended use within its own environment.
A good vendor will provide an 'out-of-the-box' compliant system and extensive documentation (often called a validation pack) to make your validation process much faster and easier, but they cannot perform the final validation for you.
