JWT Claims Reference

Summary

Browse and search all RFC 7519 registered JWT claims — each entry includes the claim name, description, expected value type, and usage notes.

How it works

1. Use the search box to filter claims by name, description, or keyword.
2. Click any claim row to expand full details including value type and usage notes.
3. Use the category filter buttons to view only Header, Payload, or IANA-registered claims.
4. Click the RFC link on any claim to jump directly to the relevant spec section.
5. Copy a claim name to clipboard with the copy icon next to each claim.

Use cases

• Look up the correct claim name when building a JWT payload in your API.
• Understand what value format is expected for exp, nbf, or iat (NumericDate).
• Verify which claims are required vs. optional per the JWT spec.
• Reference aud semantics when configuring audience validation in your auth middleware.
• Onboard new team members to JWT structure without hunting through the RFC.
• Check the purpose of an unfamiliar claim found in a decoded token.
