Open Badges are a specific type of digital credential built on a technical standard originally developed by Mozilla and now maintained by IMS Global Learning Consortium. Unlike a regular PDF certificate, an Open Badge is a structured file that contains embedded metadata describing who issued it, who received it, what it represents, and how the claim can be verified.
This guide explains how Open Badges work technically, what they can and cannot do, and when they are the right choice for your credential program.
What Is Inside an Open Badge?
An Open Badge is a PNG or SVG image file with JSON metadata baked into it. That metadata includes the badge class, which describes the achievement, the assertion, which links the badge to a specific recipient, and the issuer profile, which identifies the organization that awarded it. All of this travels with the badge file wherever it goes.
The assertion is the most important part. It contains a verification URL or a cryptographic signature that allows anyone with a compatible tool to check whether the badge is genuine and whether it was actually issued to the person presenting it. This makes Open Badges fundamentally different from a JPEG of a certificate, which contains no verifiable data at all.
Hosted Verification vs. Signed Badges
Open Badges support two verification methods. Hosted verification points to a URL on the issuer's server that contains the assertion data. When someone verifies a hosted badge, their tool fetches the assertion from that URL and checks that the badge matches. This is the most common method and works well as long as the issuer's server remains online.
Signed badges use a cryptographic signature instead of a hosted URL. The assertion is signed with the issuer's private key and embedded directly in the badge. Verification requires the issuer's public key, which can be published anywhere. Signed badges work even if the issuer's server goes offline, making them more durable for long-term credentials.
The Open Badges Standard Versions
The current standard is Open Badges 3.0, which aligns with the W3C Verifiable Credentials Data Model. This makes Open Badges 3.0 compatible with the broader Verifiable Credentials ecosystem, including decentralized identity systems. Earlier versions, 1.1 and 2.0, are still widely used and most platforms support them, but 3.0 is the direction the ecosystem is moving.
When choosing a badge platform, ask which version of the standard it supports and whether its badges are compatible with major display platforms like Badgr, Credly, or LinkedIn's certification section.
Where Learners Display Open Badges
Recipients can add Open Badges to LinkedIn, embed them in email signatures, display them on portfolio websites, and upload them to backpack services that aggregate badges from multiple issuers. LinkedIn has native support for Open Badges, allowing recipients to add them to their Licenses and Certifications section with a direct link to the verification page.
The portability of Open Badges is one of their key advantages over proprietary certificate formats. A learner who collects badges from multiple providers can display them all in one place, creating a richer picture of their skills than any single certificate could provide.
What Open Badges Cannot Do
Open Badges are a technical standard, not a quality standard. The specification describes the format and verification mechanism but says nothing about the rigor of the assessment behind the badge. A badge for completing a 10-minute quiz looks identical in format to a badge for passing a six-month professional examination.
The trust associated with an Open Badge comes entirely from the reputation of the issuer and the quality of the program behind it, not from the format itself. This is why building a strong certification program with rigorous assessment is more important than the credential format you choose.
Badge Metadata: What to Include
Good badge metadata increases the credibility and usefulness of your credential. At a minimum, include the badge name, a clear description of what the recipient demonstrated to earn it, the issue date, and any expiry date. Optionally include alignment to external standards or competency frameworks, evidence links, and tags that help categorize the skill.
The description field is frequently underused. Instead of 'Completed the Digital Marketing Fundamentals course,' write what the recipient can actually do: 'Demonstrated ability to plan, execute, and analyze a digital marketing campaign across search and social channels.' This specificity makes the badge far more useful to employers evaluating candidates.
Badge Pathways and Collections
One of the most effective uses of Open Badges is creating pathways where earning a series of badges leads to a higher-level credential. Learners collect foundational badges that unlock intermediate ones, which culminate in a master credential or professional certification. This structure keeps learners engaged across a longer learning journey and creates natural progression milestones.
The pathway structure also makes the final credential more legible to outsiders. Instead of a single opaque certificate, employers can see the full stack of competencies that underpins it, each verified independently.
Open Badges vs. Standard Digital Certificates: Which to Choose?
If your primary goal is issuing completion certificates for a training program, a standard digital certificate with a unique verification URL and QR code is usually sufficient. Open Badges add complexity without adding proportionate value in most straightforward training scenarios.
Choose Open Badges when interoperability matters. If your learners will present credentials across multiple organizations, systems, or countries, and if those systems need to read and verify the credential programmatically, Open Badges' standardized format becomes essential. They are also the right choice if you want to participate in a broader badge ecosystem where learners collect credentials from multiple providers.
Getting Started With Open Badges
To issue Open Badges, you need a platform that supports the standard, a defined badge class for each credential you want to award, and a way to deliver badges to recipients. Most platforms handle delivery via email, allowing recipients to claim their badge to a backpack or download the badge file directly.
Start simple. Design one badge for your most commonly awarded credential, test the full issuance and verification workflow, and gather feedback from your first cohort of recipients before building out a full badge library. The standard is robust, but the operational process around it needs to be smooth for both issuers and recipients.
The Open Badges Standard: What It Is
Open Badges is a specification developed by Mozilla and now maintained by IMS Global (now 1EdTech). It defines a technical format for digital credentials that can be issued, verified, and displayed across any platform that supports the standard.
The core idea is interoperability. A badge issued by one organization should be displayable and verifiable on any compliant platform, including LinkedIn, credential wallets, and employer verification systems. The badge carries its own verification data inside the file.
What Is Inside an Open Badge
An Open Badge is more than an image. The badge file (typically a PNG or SVG) contains embedded metadata including:
- The recipient's identity (typically a hashed email)
- The issuing organization's name and URL
- The badge name and description
- The criteria for earning the badge
- The issue date and optional expiry date
- A verification URL pointing to the badge assertion
This metadata is what makes a badge verifiable. Anyone with a badge verification tool can check the embedded data against the issuer's record without contacting the issuing organization.
How Badge Verification Works
Badge verification follows a defined protocol. The verifier reads the badge metadata, extracts the assertion URL, and fetches the assertion from the issuer's server. The assertion contains the claim that a specific recipient earned a specific badge at a specific time.
If the data in the badge matches the assertion on the server and the issuer's identity checks out, the badge is verified. This process is automated. A human verifier does not need to make any manual checks.
Open Badges vs Traditional Certificates
Traditional digital certificates are typically PDF files with a verification URL added as a QR code or hyperlink. They are human-readable documents. The verification mechanism is external.
Open Badges are machine-readable credentials. The verification data is inside the badge itself. This makes badges more interoperable across technical systems but less immediately readable to humans who are not using a badge platform.
For most practical purposes: use certificates when the credential needs to be printed or shared as a document. Use badges when the credential needs to live in a digital wallet or be verified programmatically.
When to Use Open Badges
- When recipients will aggregate credentials from multiple issuers in a single wallet
- When you need interoperability with platforms that support the Open Badges standard
- When you issue micro-credentials for specific skills rather than whole programs
- When recipients are technical and understand how to use badge wallets
Open Badges and LinkedIn
LinkedIn supports adding certifications and licenses to profiles, but it does not have native Open Badge verification. Recipients typically add a badge to LinkedIn by providing the credential URL and a credential ID. The badge image can be used as the certificate image.
Some badge platforms integrate directly with LinkedIn and can pre-populate the add-credential form. This removes friction for recipients and increases the likelihood they share their credential.
1EdTech maintains the Open Badges specification and publishes the technical standards for badge issuance, verification, and interoperability across platforms.

Frequently Asked Questions
What is an Open Badge?
An Open Badge is a digital credential that follows the Open Badges specification maintained by 1EdTech. The badge file contains embedded metadata including the recipient's identity, the issuing organization, the criteria for earning the badge, and a verification URL. This makes badges verifiable across any compliant platform.
How do I verify an Open Badge?
Use a badge verification tool like Badgr or the verifier on 1EdTech's website. The tool reads the badge's embedded metadata, fetches the assertion from the issuer's server, and confirms whether the badge is genuine and unmodified.
What is the difference between an Open Badge and a digital certificate?
A digital certificate is typically a PDF or hosted document with an external verification link. An Open Badge is a machine-readable file with verification data embedded inside it. Certificates are more readable for humans. Badges are more interoperable across technical systems and credential wallets.
Can Open Badges be added to LinkedIn?
Yes, but not natively. Recipients add their badge to LinkedIn as a certification by providing the badge URL and any credential ID. Some badge platforms pre-populate the LinkedIn add-credential form to remove friction. LinkedIn does not verify badge assertions directly.
Should I issue Open Badges or traditional certificates?
Both serve different purposes. Certificates are better for program completions that need a formal document. Open Badges are better for micro-credentials and skill recognition that needs to be aggregated with credentials from other issuers. Many organizations issue both for the same achievement.
