- Do not dial a leading ‘0’ in the international call sequence – it is only used in the Netherlands for domestic long distance calls.
- A leading '+' in the phone number means 'dial your country's exit code'.
- Calling from a mobile phone: dial from on the country where you're currently located.
- Calling from a VoIP or satellite phone: dial from on the country where the phone is registered.
The Netherland’s country code may be mislabeled:
- Country code 0031 (exit code of ’00’ used in many European, Asian, and African nations followed by the Netherlands country code of ’31’).
- Country code 01131 (exit code of ‘011’ used in the United States and Canada followed by the Netherland’s country code of ’31’).
When calling to a mislabeled country code, remove the exit code from the call sequence and replace it with the exit code of the country the call is dialed from.
Use the same call sequence.
Mobile phone numbers occupy most area codes starting with ‘6’.
When calling a mobile phone user, dial to the country where the mobile phone is registered, regardless of where the person is roaming.
VoIP phone numbers based in the Netherlands are accessed with the same call sequence as a regular landline phone.
VoIP phone numbers in the Netherlands occupy area code ‘091’ (’91’ when called from outside the country).
When calling a VoIP phone user, dial to the country where the VoIP phone is registered, regardless of where the person is roaming.
The Netherlands do not have a country-specific satellite phone system.
Most satellite phones operate on their country code – calls to these satellite phones follow their call sequence.
Use the same call sequence.
