A communication apparatus accepts from a user a display setting regarding a two-dimensional code in which one or more parameters related to communication with a communication apparatus are encoded, and determines a parameter set that includes one or more parameters to be encoded in the two-dimensional code related to communication with the communication apparatus. When the accepted display setting is a first setting, a first two-dimensional code for a first application in which a first parameter set corresponding to the first setting is encoded is displayed, and when the accepted display setting is a second setting, a second two-dimensional code for a second application in which a second parameter set corresponding to the second setting is encoded and which is different from the first two-dimensional code is displayed, and wherein the first two-dimensional code includes a parameter that is not included in the second two-dimensional code.
