Teledata

We have combined the data of all the major telephone companies in Denmark, to provide a one-stop solution for teledata. It is updated daily, and contains all phonenumbers that the phone companies are legally bound to make available to us. We link these phone numbers to companies, enabling you to look up the number of a company, or the owner (company or person) of a number. Additionally, we look up numbers in the CVR registry and add those to the results if they add additional value.

This API requires a Teledata subcription

Find the number of a company

To retrieve the numbers of a company, provide the lassoid to the following endpoint:

GET api.lassox.com/data/teledata/{lassoid}/phonenumbers

GET api.lassox.com/data/teledata/CVR-1-34580820/phonenumbers

{ 
    "phoneNumbers":[
        {
            "cvr": 34580820,
            "pNumber": null,
            "telephoneNumber": 51906923,
            "added": "2020-06-25T04:20:31.103",
            "movementDate": null,
            "telephoneNumberRangeStartIdentifier": null,
            "telephoneNumberRangeEndIdentifier": null,
            "supplier": "Nuuday",
            "furtherUsageConsentIndicator": false,
            "furtherUsageConsentText": null
        },
        {
            "cvr": 34580820,
            "pNumber": null,
            "telephoneNumber": 71747812,
            "added": "2020-06-26T04:02:19.55",
            "movementDate": "2021-08-22T00:00:00",
            "telephoneNumberRangeStartIdentifier": null,
            "telephoneNumberRangeEndIdentifier": null,
            "supplier": "Nuuday",
            "furtherUsageConsentIndicator": false,
            "furtherUsageConsentText": ""
        }
    ]
}

Note that the results contain a telephoneNumberRangeStartIdentifier and a telephoneNumberRangeEndIdentifier. If these are set, the phonenumbers from start to end are also valid for this company.
