Quick answer
Use this guide as a starting point, then confirm account-specific rules with the provider listed on your bill.
What to include
Use the payment stub, correct payee, account number in the memo, and official remittance address.
Timing risk
Mail delivery and provider posting can take days. Do not assume a mailed check has posted until the account balance changes.
Past-due accounts
If a shutoff notice is involved, use a faster official method and ask customer service what amount is needed to stop service action.
Keep records
Keep a copy of the check, money order receipt, tracking number, and provider confirmation if available.
