# Service class

**Element type: Required**

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

As a seller, do you derive more revenue primarily from local or long distance phone calls? Your integration must provide a method for specifying your company's service class. Available business classes are:

-   `0`: Primary local
-   `1`: Primary long distance

This setting is specified using the `svcl` 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"
  },
  ...
} 
```
