Overview

CLI routes to Netherlands

A CLI route to Netherlands is a wholesale path that keeps the caller ID you send intact all the way to the handset. CLIRoutes only places CLI-tier traffic on paths that passed CLI test calls on Netherlands’s main networks, and removes paths that stop passing.

Dutch CLI routes deliver your assigned 0xx or 088 number end-to-end on KPN, VodafoneZiggo and Odido. We test display per network and keep Dutch-CLI traffic on paths where it is accepted as legitimate.

Since 2021 the Netherlands has been an opt-in market for consumer telemarketing. Most traffic is customer care, existing-customer calls and B2B.

Caller ID rules in Netherlands

A practical summary for operations teams, not legal advice. Confirm current requirements with counsel before you launch.

Last reviewed

Caller-ID presentation

The Telecommunications Act requires a valid, assigned CLI and forbids suppressing it on telemarketing calls. Since July 2021, telemarketing to consumers needs prior consent unless the person has been a customer within the past three years. Dutch operators increasingly filter calls from abroad that present Dutch numbers without authorisation.

Opt-in telemarketing

Telemarketing calls to consumers require prior consent unless there is an existing customer relationship, and that exception is time-limited.

Number presentation

Marketing calls must present a valid, assigned number that can be called back.

Data protection

GDPR applies to call records and recordings; the Dutch DPA enforces it.

Calling hours

No statutory window, but consumer complaints guide practice towards weekday daytime and early evening.

Dialing & setup

Dialing Netherlands correctly

  • Drop the trunk 0: 020 123 4567 becomes +31 20 123 4567.
  • 088 and 085 numbers are popular company lines and display well as CLI.
  • An existing-customer relationship only covers calls within three years of the last purchase, and only for similar products.
  • Every telemarketing call must tell the person how to opt out of future calls.

Caller ID best practice

Present a valid Dutch number assigned to you, never suppress CLI on marketing calls, and keep proof of consent for every consumer contact.

FAQ

Netherlands CLI routes: FAQ

Can’t find what you need? Our routing team answers within the hour, around the clock.

Is the Netherlands an opt-in market?

Yes. Telemarketing to consumers requires prior consent, with a limited exception for existing customers. We review campaign type before enabling Dutch outbound sales traffic.

Can I present a non-Dutch CLI?

You can present any valid number you are authorised to use, but Dutch numbers perform best and are easiest for recipients to call back.

What counts as an existing customer for Dutch telemarketing?

Someone who bought from you within the last three years. You may call them about similar products without new consent, provided you offered an opt-out when you collected their details.

Is the Bel-me-niet Register still used?

It has been largely superseded by the 2021 opt-in rule for consumers. Your own opt-out records and consent evidence are what matter now.

Can I present an 088 number?

Yes, if it is assigned to you. 088 numbers are common company numbers in the Netherlands and are trusted by recipients.

Which caller ID can I present on Netherlands calls?

Only numbers you own or are authorised to use. Present a valid Dutch number assigned to you, never suppress CLI on marketing calls, and keep proof of consent for every consumer contact.
