My mail rewards enter numbers

It sounds like you're trying to enter numbers for a mail rewards program. Can you please provide more context or details about the program and what you're trying to do? For example:

• What is the name of the rewards program?
• What kind of rewards are you trying to earn (e.g. points, cash, gift cards)?
• What are the numbers you're trying to enter (e.g. a code, a PIN, a tracking number)?
• Have you tried entering the numbers already, and if so, what happened?

The more information you can provide, the better I'll be able to assist you!
