# Business class

**Element type: Required**

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

Your integration must provide a method for specifying your company's business class. This setting refers to the seller regulatory status for local exchange carriers. Available business classes are:

-   `0`: Incumbent Local Exchange Carrier ([ILEC](https://en.wikipedia.org/wiki/Incumbent_local_exchange_carrier))
-   `1`: Not an [ILEC](https://en.wikipedia.org/wiki/Incumbent_local_exchange_carrier)

Even if you're not a local exchange carrier, your integration must provide this option.

This setting is specified using the `bscl` field in the [CompanyData](https://developer.avalara.com/api-reference/communications/v2/models/CompanyData/) model.

**View example**:

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