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

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
