An Existing Business Relationship (EBR) provides an exemption to DNC rules under certain conditions. The EBR API allows you to add and manage EBR records for phone numbers. In addition the EBR API can be used to store Consent. A consent record is a Permission “P” EBR record — use this type whenever a consumer opts in with express written consent (for example, a signed web consent form or a consent checkbox with the required disclosures). You should ensure you have the proper consent from the customer for the customer’s jurisdiction before sending this. This will allow you to contact the customer for the purposes of marketing and sales until you remove the Permission EBR or Add to Internal DNC.

Handling a consumer who opted out and later opts back in? See Handling Opt-Outs and Opt-Ins for how Permission EBRs and the Internal DNC list interact.

To add or refresh EBR records and scrub numbers in a single request, use Scrub + Add EBR instead of calling this endpoint separately.

Request

Headers

Your API Key

string

required

Must be application/json

Request Body

integer

When set to 1, if an EBR record already exists for the phone number being added and the existing EBR is “better” than the one being added, the existing EBR will not be overwritten. Federal EBR expiration dates are used to determine which EBR is better (longer remaining validity = better).

array

required

Array of EBR records to add.

Show EBR Record Object

string

required

10-digit phone number(s). For multiple numbers, comma-separate them (e.g., "5039367187,7075276405").

string

required

EBR type:

S - Sale/Purchase
I - Inquiry
P - Permission
T - Trial (currently only for Newspaper Trials in North Dakota)

string

required

Date of last contact in MM/DD/YYYY format (e.g., "11/11/2020").

string

Date when written obligation ends (New Jersey only).

string

Your internal tracking string.

string

Company/product/brand name used to establish the EBR.

string

Email address (100 characters max).

Example Request

curl --location 'https://www.dncscrub.com/app/main/rpc/ebr' \
  --header 'loginId: YOUR_API_KEY' \
  --header 'Content-Type: application/json' \
  --data '{
    "ebrList": [
      {
        "phoneNumber": "5039367187",
        "type": "I",
        "dateOfLastContact": "11/11/2020"
      }
    ]
  }'

const response = await fetch("https://www.dncscrub.com/app/main/rpc/ebr", {
  method: "POST",
  headers: {
    loginId: "YOUR_API_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    ebrList: [
      {
        phoneNumber: "5039367187",
        type: "I",
        dateOfLastContact: "11/11/2020",
      },
    ],
  }),
});

using (var client = new HttpClient())
{
    client.DefaultRequestHeaders.Add("loginId", "YOUR_API_KEY");

    var ebrData = new
    {
        ebrList = new[]
        {
            new
            {
                phoneNumber = "5039367187",
                type = "I",
                dateOfLastContact = "11/11/2020"
            }
        }
    };

    var content = new StringContent(
        JsonSerializer.Serialize(ebrData),
        Encoding.UTF8,
        "application/json"
    );

    var response = await client.PostAsync(
        "https://www.dncscrub.com/app/main/rpc/ebr",
        content
    );
}

{
  "success": true
}

Add Multiple EBRs

Add multiple EBR records in a single request:

curl --location 'https://www.dncscrub.com/app/main/rpc/ebr' \
  --header 'loginId: YOUR_API_KEY' \
  --header 'Content-Type: application/json' \
  --data '{
    "ebrList": [
      {
        "phoneNumber": "5039367187",
        "type": "S",
        "dateOfLastContact": "06/14/2023"
      },
      {
        "phoneNumber": "7072842774",
        "type": "I",
        "dateOfLastContact": "07/02/2023"
      }
    ]
  }'

This adds:

Phone 5039367187 with a Sale EBR dated 06/14/2023
Phone 7072842774 with an Inquiry EBR dated 07/02/2023

Multiple Phone Numbers Per Record

You can also add the same EBR to multiple phone numbers in one record:

{
  "ebrList": [
    {
      "phoneNumber": "5039367187,7075276405",
      "type": "I",
      "dateOfLastContact": "11/11/2020"
    }
  ]
}

Preserve Better EBR Records

Use keepBetterEBR to prevent overwriting existing EBR records that have longer remaining validity:

{
  "keepBetterEBR": 1,
  "ebrList": [
    {
      "phoneNumber": "5039367187",
      "type": "I",
      "dateOfLastContact": "11/11/2024"
    }
  ]
}

When keepBetterEBR is set to 1, the system compares federal and state EBR expiration dates. If the existing EBR expires later than the new one would, the existing record is preserved. This is useful when importing EBR data to avoid accidentally downgrading your compliance coverage.

Response

Status Code	Meaning
`200`	Success
`4xx`	Error - response body contains the reason

EBR Types

Type	Description
`S`	Sale/Purchase — consumer bought or transacted with you
`I`	Inquiry — consumer asked about your products or services
`P`	Permission — consumer gave express written consent to be contacted (opt-in). Only this type can override an Internal DNC entry
`T`	Trial (currently only for Newspaper Trials in North Dakota)

EBR Expiration

EBR exemptions expire based on federal rules:

EBR Type	Expiration Period
Sale/Purchase (`S`)	18 months from date of last transaction
Inquiry (`I`)	3 months from date of inquiry

State rules may vary. Some states have shorter exemption periods or additional requirements.

Best Practices

Track Reference Numbers

Use the referenceNum parameter to store your internal tracking ID for audit purposes.

Use Accurate Dates

The dateOfLastContact should be the actual date of the business relationship event, not the current date.

Choose Correct Type

Select the appropriate EBR type - using the wrong type could result in compliance issues. In particular, opt-ins backed by express written consent must be sent as Permission (P) — a Sale or Inquiry EBR will not override an Internal DNC entry.

Use keepBetterEBR When Importing

When bulk importing EBR records, use keepBetterEBR: 1 to preserve existing records with longer validity periods and avoid accidentally reducing your compliance coverage.
