# Detect whether a document is supported

There are two distinct questions you might ask:

- Is this document type supported by BlinkID at all?
- Did the SDK classify the document it just processed, and as what?

## Is the document type supported by BlinkID

BlinkID supports a large, continuously growing catalog of identity documents.
The authoritative answer to "can BlinkID read this document" is the published list of supported documents.
See [Supported documents](./supported-documents.mdx) for the full catalog.

At runtime, you find out that a document is not supported through the per-frame processing status.
After processing an image, read `inputImageAnalysisResult.processingStatus`.
A value of `unsupported-document` means the recognizer does not support the document in the frame.

The same status also appears when a document is supported by BlinkID but excluded by a document class filter you configured.
From the SDK's perspective these are indistinguishable: in both cases the document is "unsupported" relative to what the current session will accept.
See [How to restrict documents](restrict-documents.md) for that case.

  <TabItem value="web" label="Web (TS)" default>

  ```typescript
  const processResult = await session.process(imageData);
  const status = processResult.inputImageAnalysisResult.processingStatus;

  if (status === "unsupported-document") {
    console.log("This document is not supported.");
  }
  ```

  <TabItem value="android" label="Android (Kotlin)">

  ```kotlin
  val processResult = session.process(inputImage).getOrThrow()
  val status = processResult.inputImageAnalysisResult.processingStatus

  if (status == ProcessingStatus.UnsupportedDocument) {
      println("This document is not supported.")
  }
  ```

  </TabItem>
  <TabItem value="ios" label="iOS (Swift)">

  ```swift
  let frameResult = try await session.process(inputImage: inputImage)
  let status = frameResult.processResult?.inputImageAnalysisResult.processingStatus

  if status == .unsupportedDocument {
      print("This document is not supported.")
  }
  ```

## Inspect what the SDK classified

When BlinkID does support and recognize a document, the result has a `documentClassInfo` structure describing what was classified.

In `documentClassInfo`, check the `countryName` and `documentType` for your main source of information.

Check the [supported documents](./supported-documents.mdx) to understand which values you can get for country/type.

<Tabs queryString="platform">

  <TabItem value="web" label="Web (TS)" default>

  ```typescript
  const result = await session.getResult();
  const classInfo = result.documentClassInfo;

  console.log("Country:", classInfo?.countryName);
  console.log("Type:", classInfo?.documentType?.id);
  ```

  </TabItem>
  <TabItem value="android" label="Android (Kotlin)">

  ```kotlin
  val result = session.getResult().getOrNull()
  val classInfo = result?.documentClassInfo

  println("Country: ${classInfo?.countryName}")
  println("Type: ${classInfo?.documentType?.id}")
  ```

  </TabItem>
  <TabItem value="ios" label="iOS (Swift)">

  ```swift
  let result = session.getResult()
  let classInfo = result?.documentClassInfo

  print("Country:", classInfo?.countryName ?? "")
  print("Type:", String(describing: classInfo?.documentType?.documentTypeId))
  ```

  </TabItem>
</Tabs>
