For select accounts, you can sign up to receive a PDF copy of your invoice by email. You can select whether you want a regular PDF (no password) or a secure PDF (password-protected). To help keep your information secure, we recommend you choose the secure option. Your PDF password is the billing zip code for the account. When you enroll an account, you can add up to five email addresses to receive the PDF. Please allow 1–2 billing cycles for us to process your request.
