Telephone numbers in the Netherlands are administered by the Ministry of Economic Affairs, Agriculture and Innovation of the Netherlands. The telephone numbering plan may be grouped into three general categories: geographical numbers, non-geographical numbers, and numbers for public services.

Geographical telephone numbers have nine digits and consist of an area code of two or three digits and a subscriber number of seven or six digits, respectively. When dialled within the country, the number must be prefixed with the trunk access code 0, identifying a destination telephone line in the Dutch telephone network.

Non-geographical numbers have no fixed length, but also require the dialling of the trunk access code (0). They are used for mobile telephone networks and other designated service types, such as toll-free dialling, Internet access, voice over IP, restricted audiences, and information resources.

In addition, special service numbers exist for emergency response, directory assistance, and other services by the public authorities.
