Is it okay to write a novel without using a real ID number?

Of course, one could write a novel without using a real ID number. It all depended on the plot and background of the novel. In some cases, it may be necessary to use the ID number for identity verification or in some cases to obtain certain information, but this does not necessarily mean that a real ID number must be used. In a fictional world, ID numbers can be presented in any way, such as using fictional numbers or symbols to replace real numbers. If the novel needed some information related to the ID card number, it could be presented through imagination or fiction instead of using the real ID card number. It is important to note that using a real ID number in a fictional world may cause legal problems, so it is necessary to ensure that the plot of the novel is legal and does not violate the rights of others.
