An SSID stands for Service Set Identifier and is the name assigned to a Wi-Fi network when a router is set up. It is a sequence of characters that uniquely names a Wi-Fi network and is used to create a hotspot and broadcast its network within its vicinity. When attempting to connect a device to a Wi-Fi network, users see a list of all available Wi-Fi networks and use the SSID as a name to identify the particular network they want to use. SSIDs can be up to 32 characters long and are usually customizable). Router manufacturers may create default SSIDs by using the manufacturers name and adding random numbers and letters. Changing the default SSID to another string of characters is also common practice to cause less confusion in an area with multiple wireless networks. Each access point advertises its presence several times per second by broadcasting beacon frames that carry the ESS name. A user can change the SSID to whatever they want, but it should be something recognizable without having any personally identifying information in it.
