What to check before using the 31 country code
Country codes are only one part of an international phone number. Exit codes, area codes, mobile prefixes, and local numbering rules can change how the final number should be dialed.
Exit code or plus format
On a mobile phone, the plus sign usually replaces exit codes such as 00 or 011. From a landline, use the international access code for the country you are calling from, then 31.
Country calling code, dial code, or prefix
People may call 31 the Netherlands country code, country calling code, phone code, dial code, or international prefix. In each case, use +31 before the rest of the Netherlands number.
Mobile phone or landline
After +31, the next digits may be an area code, mobile prefix, service prefix, or local number. Check whether you are calling a mobile phone or landline because rates can differ.
