Telephone numbers in the Netherlands are administered by the Ministry of Economic Affairs, Agriculture and Innovation of the Netherlands and may be grouped into three general categories: geographical numbers, non-geographical numbers, and numbers for public services.
Geographical telephone numbers are sequences of 9 digits (0-9) 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 required 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.
The telephone numbering plan of the Netherlands is divided into geographical, non-geographical, and special public resource telephone numbers. The dial plan prescribes that within the country dialling both geographical and non-geographical numbers requires a national network access code, which is the digit 0. The following list includes this national trunk access digit when it must be dialled before the number.
066, 084 and 087 are often used by scammers, because they are easy and cheap to register and make identification very hard.
Previously, 06-0, 06-1000 and 06-4 were used for toll-free numbers, 06-8 for shared cost, 06-9 for premium rate, and other 06-numbers for mobile numbers. 0011 and later 06-11 was used for emergency services before this changed to 112. 09 was used as the international access code before this changed to 00.
Since the reorganization of the telephone system in 1995, Dutch geographical numbers consist of 9 digits. The numbering plan implements a system of area codes. An area code consists of two or three digits. The larger cities and areas have two digits with a subscriber number of seven digits, permitting more local numbers. Smaller areas use three digits with a six-digit subscriber number.
Geographic numbers are allocated in blocks to telecommunications providers. However, a telephone number from a block allocated to a certain provider may no longer be serviced by the original assignee due to number portability; subscribers who switch providers can take their number with them.
