Dialing Tips

Remove the leading 0: When dialing internationally, drop the trunk prefix (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: Numbers in the Netherlands have 9 or 11 digits for mobiles and 9 for landlines after +31. If your call does not connect, check that no digit is missing or doubled.
Save contacts in international format: Always store phone numbers with the full +31 prefix so they work from any country.
