# Portable Document A1 (PDA1) - credential schema
## When to use
Use this skill when you issue or verify a **Portable Document A1 (PDA1)**
credential. PDA1 is the EU social security document. It states which member
state social security legislation applies to a worker who works in more than one
member state, or who is posted to another member state.
The registry gives the credential type `PortableDocumentA1` and the namespace
`org.iso.18013.5.1.pda1`. The schema supports three formats: SD-JWT VC
(`dc+sd-jwt`), W3C JWT VC (`jwt_vc_json`) and mdoc (`mso_mdoc`).
The registry keeps this schema under
`credentialSchemas/claimPathPointer/pda1`. Version **2025.7.1** is the latest
version directory, and this skill uses it. The registry publishes the schema
in three formats: `dc+sd-jwt`, `jwt_vc_json` and `mso_mdoc`.
