Required Documents for Toll-Free Numbers
There are two possible processes for porting 0800 numbers in the Netherlands. Your current service provider can confirm which applies to your case.
1. You are the registered end user and owner of the 0800 number with ACM (Netherlands Authority for Consumers and Markets)
If your company is the direct owner of the number registered with ACM, you only need to provide:
Signed Letter of Authorization (LOA) - must be signed by the account holder or an authorized representative.
Chamber of Commerce (KvK) Number - used to confirm your registration with the Dutch Chamber of Commerce.
You can read more about ACM’s number transfer process here.
2. You are not the registered end user with ACM (e.g. your number is hosted by a VoIP reseller)
If your number was provisioned through a third-party platform or reseller and is registered under their name with ACM, we’ll need to:
Initiate a transfer of rights from the current service provider to either your company or CloudTalk’s service provider. CloudTalk’s Porting Team will help guide you through this process.
A template for the ownership transfer will be provided after you submit your porting request.

Step-by-Step Porting Process
Submit a porting request to the CloudTalk Porting Team.
We check the portability and confirm details with you.
You fill out and sign the LOA.
You send us the LOA + invoice.
We submit the request to our carrier partner.
Our partner forwards the request to your current provider.
Once accepted, we’ll confirm your scheduled port date (usually 2–4 days in advance).
If rejected, we’ll share the reason and help you fix any issues before resubmitting.
Common Rejection Reasons (and How to Avoid Them)
Incorrect or mismatched information - double-check that the name and address match your current provider’s records.
Outdated invoice - make sure the invoice is recent and lists the number(s) you’re porting.
LOA not signed or signed by unauthorized person - must be signed by someone authorized on the account.
What Happens on Port Day
Your number will switch to CloudTalk on the scheduled date.
Your old provider will deactivate the number.
CloudTalk billing will start on the same day.
We recommend contacting your old provider to confirm billing has stopped.
