1+1, or sometimes written as 1x1, means performing the search on a single data source and getting a positive verification response.

2+2 (or 2x2) indicates that the search was performed using two or more different data sources and all of those returned positive verification results. Meaning, the identity was verified on all the data sources. 2+2 is also called Composite Search.

Let's take two examples to further understand it. The code snippets below are the results of two separate API calls.

1+1 Example: Here only a single data source was used which was Australia Driver Licence and the identity was verified.

{
  "countryCode": "Australia",
  "clientReference": "Test_0001",
  "reportingReference": "DZ-0e6821b7-5420-47e4-957f-9fe543865073",
  "matchStatus": "Full Match 1+1 Verification",
  "searchErrorMessage": "",
  "safeHarbour": false,
  "searchStatus": "Successful",
  "serviceResponses": {
    "Australia Government Identity Documents 1": {
      "status": 0,
      "sourceStatus": "Successful",
      "errorMessage": "",
      "identityVerified": true,
      "safeHarbourScore": "M2",
      "nameMatchScore": "1.000",
      "addressMatchScore": "N/A",
      "verifications": {
        "dateOfBirth": true,
        "documentNo": true,
        "firstName": true,
        "lastName": true
      },
      "returnedData": {}
    }
  }
}


2+2 ExampleHere two data sources were used, Australia Driver Licence and Australia Passport and on both of these the identity was verified.

{
  "countryCode": "Australia",
  "clientReference": "Test_0001",
  "reportingReference": "DZ-401ee858-c25d-4271-aa8d-5179af874b33",
  "matchStatus": "Full Match 2+2 Verification",
  "searchErrorMessage": "",
  "safeHarbour": true,
  "searchStatus": "Successful",
  "serviceResponses": {
    "Australia Government Identity Documents 1": {
      "status": 0,
      "sourceStatus": "Successful",
      "errorMessage": "",
      "identityVerified": true,
      "safeHarbourScore": "M2",
      "nameMatchScore": "1.000",
      "addressMatchScore": "N/A",
      "verifications": {
        "dateOfBirth": true,
        "documentNo": true,
        "firstName": true,
        "lastName": true
      },
      "returnedData": {}
    },
    "Australia Government Identity Documents 2": {
      "status": 0,
      "sourceStatus": "Successful",
      "errorMessage": "",
      "identityVerified": true,
      "safeHarbourScore": "M2",
      "nameMatchScore": "1.000",
      "addressMatchScore": "N/A",
      "verifications": {
        "dateOfBirth": true,
        "documentNo": true,
        "firstName": true,
        "lastName": true
      },
      "returnedData": {}
    }
  }
}
