What is what does it mean when a girl asks for your number?

When a girl asks for your number, it generally means that she is interested in getting to know you better outside of the current context or environment. It could also mean that she wants to stay in touch with you and potentially build a romantic or platonic relationship. However, it is important to remember that not all interactions or requests for numbers are romantic in nature, as some may just be for networking or purely friendly purposes. Ultimately, context and communication are key in understanding the intentions behind a girl asking for your number.
