Access Code

What Does Access Code Mean?

An access code is a series of numbers and/or letters that allow access to a particular system. An access code may be a password, although passwords are generally used in conjunction with usernames. Access codes need not be attached to a specific user; many users could use the same access code for a specific system or object without being identified as a specific user.

This term is also known as an access key.

Techopedia Explains Access Code

The access code is also used for authentication. In telecommunications, an access code is required before a user can be connected to a specific region. National access codes are used in dialing domestic numbers, while international access codes are used in dialing international numbers. A PIN is also a sort of access code that is shared between a specific user and the system.

Access codes are also used in digital systems, behaving like a locked door to limit access from the outside world. A person must have the key to gain access to the system, which is the access key or code.
