​
  1. Letter of Authorization

Where an LOA is required, the correct template for this country downloads inside the Documents step of your porting request: download it, sign it, and upload it right there. You no longer need a separate template from this guide. (Other document requirements listed below.)

​
  1. Timelines & Pricing

⚠️ Timelines may vary if submitted details do not match your current provider’s records.

​
Required Documents For Number Porting

The correct LOA templates download inside the Documents step of your porting request.

​
✅ Local & National Numbers

  • Signed LOA (Letter of Authorization)
  • VAT or TAX ID
  • Latest invoice from the current service provider
  • Address in the same city as the number within Finland
If you do not have an address in Finland, we will use a different partner carrier. In that case we will email you the correct LOA template after you submit, so you can submit your porting request in the Dashboard without attaching an LOA.

​
✅ Mobile Numbers

  • Signed Letter of Authorization
  • Latest invoice from current provider

​
✅ Toll-Free Numbers

  • Latest invoice from the current service provider
  • Signed LOA - if a template is not available to download in the Documents step, we will email you the correct template after you submit; you can submit your request without attaching it
  • VAT/TAX ID or SSN
  • Authorization from an attorney if the number is company-owned
