Replacing letters with numbers is commonly referred to as "alphanumeric substitution." This technique is often used in various contexts, such as creating passwords, coding messages, or in certain forms of digital communication. A specific example of this is "leet speak," where letters are replaced with similar-looking numbers or symbols (e.g., "A" becomes "4" or "E" becomes "3").
