Spain Porting

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

In Spain we offer porting for the following number types:

  • Geographic (local) numbers (+348, +349)
  • Non-Geographic numbers (+34901, +34902)
  • Toll-Free numbers (+34900, +34800)

Please note that most of International Phone Numbers have VOICE capability only. Only Mobile numbers have VOICE and SMS. Below are instructions for porting Spanish 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. 

Spain Porting Requirements

General requirements

  • The full list of numbers that you wish to port in E164 format, eg: (+[34][XXXXXXXX]).
  • Your Twilio Account SID (Your unique ID starting with “AC” that you can find on the main dashboard in Twilio Console).
  • Latest billing document.
  • For Toll-Free porting, ID of the signatory is required.
  • Additionally, upload compliance documents before submitting your port request. You can see the full list of required documents here.
    • Upload your documents in the Twilio Console by selecting “Phone Numbers” > “Regulatory Compliance“ > “Bundles” or follow the link here.
    • Choose the country, the phone number type and follow the instructions. Processing of the compliance documents may take up to several business days. Once your documents have been accepted, please share the associated links that start with "BU" and "AD" along with the porting request via email.

Additional restrictions and requirements for Geographic and Non-Geographic Numbers

  • Geo and Non-Geo Letter of Authorization (LOA) signed by the authorized user and/or owner of the number(s). Letter of Authorization must be in Spanish. You can use English translation for guidance. Note that the information on your LOA must match the authorized user name and service address provided by your current carrier.  

Additional requirements for Toll-Free Numbers

  • Toll-Free Letter of Authorization (LOA) signed by the authorized user and/or owner of the number(s). Letter of Authorization must be in Spanish. Note that the information on your LOA must match the authorized user name and service address provided by your current carrier.  Please make sure you include the current RN assigned by your service provider.

Spain Porting process

  1. Submit your porting request with all the requirements in place via this submission form.
  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 Spain, for more details please reach out to porting@twilio.com.
