Question: I have a phone number starting with +31. The full number I have is +31 20 665 xxxx. How do I call this number?
Answer: +31 in a phone number means “call the Netherlands.”
“+” in a phone number means “dial your country’s exit code.” In the USA and Canada this is “011.” In the U.K., France, Belgium, Germany, and many European countries, it is “00.” In Australia, it is “0011.” In Japan it is “010.” Many mobile phones can dial a plus sign and it will automatically dial the local country’s exit code.
“31” is the country code for the Netherlands.
The rest of the phone number appears to be for a phone located in Amsterdam.
To dial this phone number from within the Netherlands, do not dial the exit code or the country code (31). Add the trunk prefix 0 to the phone number. Dial 0-20-665-xxxx.
To dial this phone number from the USA or Canada, dial 011-31-20-665-xxxx.
