General police number for non-urgent matters in the Netherlands is 0900-8844.
In most of Europe, 112 is the emergency number. Dialing the number 100 or 900 on a rotary phone takes a long time, so a faster number was desired. 111 is the fastest dialable three-digit telephone number, but it’s also dialed accidentally when pressing the hook contact multiple times (e.g., during cleaning the phone). The next fastest dialable number is 112.
The three-digit number 112 also applies to mobile phones (cell phones). Most mobile phones have a list of phone numbers that can be used as emergency numbers (besides 112, for example, 911 used in the U.S., and 110 in Asia). These numbers can even be dialed on a GSM without a valid subscription, without knowing the PIN code, without the default operator being available, and without unlocking the GSM. Calls to these numbers receive priority, and mobile operators always reserve capacity to forward such calls. Additionally, location can be accurately determined directly through cell towers.

In large corporate networks, it is often not possible to make external calls from every device. Hence, it is necessary to have an internal emergency number.
Very often, this number is 2222 (if internal device numbers have four digits). Usually, this number connects to the gatekeeper or reception, which also serves as an emergency center.
There is a simple explanation for this number. Numbers starting with 1 cannot occur because the internal telephone exchange has reserved them for special functions. Internal device numbers, therefore, start with 2 or a higher digit. The number 2222 is an obvious choice as an easily remembered emergency number.
