About Netherlands Phone Numbers

Dutch mobile numbers always start with 06, followed by 8 digits. Landlines have area codes (2-3 digits) followed by 7 digits. Mobile numbers are consistently formatted.

How to Dial Netherlands Phone Numbers

To call a Netherlands phone number, the exact format depends on where the call starts. Domestic mobile calls usually keep the leading 0, while international calls to the Netherlands use the +31 country code instead.

• Within the Netherlands: Dial the full national number, including the leading 0 for standard domestic calls.
  Example: 06 12345678
• From abroad to the Netherlands: Dial +31 followed by the national number without the leading 0.
  Example: +31 6 12345678
• From the Netherlands to other countries: Dial 00, then the country code, then the full phone number.
  Example: 00 1 212 555 0123

Note: Dutch domestic mobile numbers commonly begin with 0, but that prefix is dropped in international format.
