ENUM Domains


In case of doubt with regard to the legitimate holder of a telephone number, our ENUM Domain Terms and Conditions entitle DENIC to disconnect the ENUM domain. However, before this happens, we will always try to clarify the situation, consulting all parties involved.

Complaints about supposedly wrong ENUM domain delegations can be submitted to DENIC by e-mail, fax or letter.

The case will then be clarified, step by step, within a clearly defined time framework. DENIC and the provider responsible for the domain will do everything to enable ENUM COMPLAINTS to be clarified as quickly as possible. Upon presentation of the correct data, they may arrange for the domain to be delegated newly if required.

If it can be proven that the ENUM delegation was wrong, DENIC will have the right to terminate the Domain Contract without notice.  Furthermore, we will keep records of such cases.

Parties Entitled to File ENUM COMPLAINTS

The ENUM COMPLAINT procedure may be started by:

  • DENIC members
  • The network operator of the telephone number
  • Legitimate holders of an E.164 telephone number
  • Someone else acting on behalf of the legitimate holder, submitting corresponding proof
  • Third parties (in justified cases)

Workflow of an ENUM COMPLAINT:

Step 1:

One of the parties entitled to do so initiates the COMPLAINT procedure. The legitimate holder of the E.164 number is required to identify themselves before submitting a complaint and also to submit proof to DENIC that they really are the legitimate holder of the number concerned. A DENIC member acting on behalf of the legitimate holder must validate the holder's legitimacy or demand evidence of such validation. The network operator, too, has the right to initiate the ENUM COMPLAINT procedure with DENIC once the validation information is available.

Step 2:

DENIC checks the evidence submitted regarding the right to use the telephone number and, if necessary, requests further documentation from the ENUM domain holder and the DENIC member in charge, or the holder's provider.

Step 3:

After checking the evidence and information obtained, DENIC decides whether the request to delete the ENUM domain will be executed or rejected. All parties involved will be informed of this decision. If the request is executed, DENIC will terminate the existing registration contract without notice. The ENUM domain may then be re-registered.
