If the prefix or suffix of a textbox is deterministic, there is no need to ask the user to remember and type, just display them as labels before and after the textbox, then prepend or append them to the number entered by the user using JavaScript before submission. As for allowing only numbers in the textbox, there are many examples on the Internet, such as this one: http://stackoverflow.com/questions/7295843/allow-only-numbers-to-be-typed-in-a-textbox[^].
