Dialing Tips

Remove the leading zero: When dialing internationally, drop the trunk prefix (usually 0) that is used for domestic calls in Netherlands.
Use the + notation: From a US mobile phone, use +31 instead of 011 31.
Verify the number length: Make sure you have the correct number of digits. If your call does not connect, check whether you need to add or remove an area code digit.
Save contacts in international format: Always store phone numbers with the full +31 prefix so they work from any country.
