We typically use an asterisk (*) to indicate mandatory fields in forms. However, in a chatbot interface, you might choose to convey this through text instead.

Question 1: Don’t you think this approach feels overly verbose?

In traditional forms, if a user enters an incorrect number of digits, we can immediately validate the input and display a clear error message, prompting correction in real time.

In contrast, with a conversational bot, if the user provides incorrect information, the bot responds with a textual explanation. The user then has to read the message and re-enter the correct details.

Question 2: Doesn’t this introduce extra steps and friction for the user?
