Question

when I tried to print an envelope error message word needs numbers between 1 and 31

Answer 1

Hi, I'm John! I will help you with this.

To help narrow down the issue:

1. What is the exact error message you see?
2. Does it happen only when printing envelopes, or also when opening Word documents?
3. What version of Word are you using (Microsoft 365, Word 2021, etc.)?
4. Have you recently changed your Windows regional date format or language settings?

The error "Word needs numbers between 1 and 31" often points to Word reading an invalid date value from Windows regional settings, a mail merge field, or the envelope template itself.
