# Company identifier

**Element type: Required**

**Endpoints/models used:** [CompanyData](https://developer.avalara.com/api-reference/communications/v2/models/CompanyData/)

Your integration must allow for a company identifier to be used in reporting. This is done using the `idnt` flag in the [CompanyData](https://developer.avalara.com/api-reference/communications/v2/models/CompanyData/) model. This field is optional for end users. The ID can either represent your company, or, if you’re a third-party billing provider, it can represent one of your clients.

**View example**:

```
{
  "cmpn": {
    "bscl": 0,
    "svcl": 0,
    "fclt": true,
    "frch": true,
    "reg": true,
    "excl": [
      {
        "ctry": "string",
        "st": "string",
        "excl": true
      }
    ],
    "idnt": "string"
  },
  ...
} 
```
