Such codes can be used in combination with other security systems, such as keypads, card readers or biometric systems, and help ensure only approved personnel have access to the area in question.

How do you find a 7 digit number?

One method is to use a random number generator online. You can search for free online random number generators and enter the number of digits you need – i. e. 7. This will then generate a random seven digit number.
