Denmark Porting

The following topics are discussed in this guide. Click a topic to skip directly to this information:

We offer porting for the following number types in Denmark:

  • Local (Geographic)
  • Toll-Free (+4580)

Please note that Danish local numbers only have Voice capabilities and can not be used to send SMS. Below are instructions for porting Danish phone numbers into Twilio. You can find porting summary and timelines here.

Once your request is received, we will place your order on your behalf using a legal document called Letter of Authorisation, which states you are giving the gaining operator the authority to act on your behalf with regards to your numbers. The order will be placed with the losing communication provider, for them to validate/accept the port order. 

Denmark Porting Requirements

General requirements

  • The full list of numbers that you wish to port in E164 format, eg: [+][45][XXXXXXXX].
  • Letter of Authorization (LOA) signed by the authorized user and/or owner of the number(s). Note that the information on your LOA must match the authorized user name and service address provided by your current carrier. Make sure you are stating a valid Company CVR number on the porting form.
  • Your Twilio Account SID (Your unique ID starting with “AC” which you can find on the main dashboard in Twilio Console).
  • Add your local service address here (must be within Denmark). Then, please share the associated link(s) that start with "AD" for us to connect your phone number(s) to the correct address.

Additional requirements for Local (Geographic) numbers

Additionally, before submitting a port request there are some documents required by the compliance regulations. You can see the full list here

  • To upload your documents please select “Phone Numbers” > “Regulatory Compliance“ > “Bundles” in your console menu or just follow the link here.
  • Choose country, phone number type and follow the instructions. Processing of the documents may take up to several business days. As soon as you get a notification that your documents have been accepted, email us back to resume your porting request.
  • Please share the associated links that start with "BU" and "AD" for us to connect your phone number(s) to the correct address.

Denmark Porting process

  1. Submit your porting request with all the requirements in place to porting@twilio.com
  2. Twilio approves the port request. If everything in Step 1 is correct, you can expect Twilio to approve your port request within 24 business hours.
  3. Twilio submits the number to the Carrier Partner. This can take up to 24 business hours. Your request is then submitted to your soon-to-be former carrier as a port request. During this time, do not close your account with your carrier and keep your numbers active.
  4. Twilio’s Carrier Partner reaches out to the Losing Carrier. This can take around one week to complete.
  5. Response from the carrier. At this point, your request is either approved or rejected:
    • Approved: If approved, Twilio will notify you about a porting date. 
    • Rejected: Rejections can occur due to various reasons. For example, invalid VAT Number or invalid/incomplete range of numbers. Read more about common reasons for port request rejections here. Additionally, you will likely need to reach out to your losing carrier to find out what’s needed to move forward. Rejections may add an undetermined amount of time to your porting request.
  6. Twilio reaches out to you with a porting date. Twilio emails you with a porting date and time slot if known. Your number is on your Account and can be visible in the Twilio Console.
  7. Configure your number. It is critical to configure your number prior to the porting date. This will minimize the service downtime. You can configure the numbers from the Twilio Console.
  8. Your phone number is with Twilio. Once your number(s) is routing to Twilio and everything works as expected, you can remove the number(s) from your former provider.

We charge a one-time porting fee for Slovenia, for more details please reach out to porting@twilio.com.
