The fastest way to pay is through the Mississippi Power website or mobile app
You can pay your Mississippi Power bill online at mississippipower.com by logging into your account and selecting the payment option. The website lets you pay immediately with a bank account or debit card, and you'll see your payment processed within one business day. If you prefer not to create an online account, you can also pay as a guest without logging in — the process takes about five minutes.
Mississippi Power also has a mobile app available on iOS and Android that works the same way. Download it, enter your account number (found on your bill), and pay directly from the app. Both the website and app show your current balance, due date, and payment history, so you can track what you owe before you pay.
If you want to avoid a fee, pay from your checking or savings account rather than a credit or debit card. Mississippi Power does not charge a fee for bank account payments, but credit and debit card payments typically include a processing fee of 2 to 3 percent.

Paying by mail or phone if you prefer not to go online
If you do not have internet access or prefer to mail a check, send your payment to the address printed on your bill. Include your account number and the payment stub with your check. Mail payments typically take 7 to 10 business days to reach Mississippi Power, so send it well before your due date to avoid a late fee.
You can also pay by phone by calling Mississippi Power's customer service line. The phone number is on your bill. Have your account number ready, and a representative will walk you through the payment over the phone using your bank account or debit card. Phone payments process the same day you call.
Setting up automatic payments so you never miss a due date
Automatic payments are one of the easiest ways to stay on top of your bill. Log into your account at mississippipower.com, go to the payment settings, and choose to pay the full balance or a set amount each month on a date you pick. Mississippi Power will pull the payment from your bank account automatically on that date.
You can change or cancel automatic payments anytime through your online account. If you want to pause a payment because of a billing dispute or a change in your situation, you can do that without penalty. Just remember to turn it back on once the issue is resolved, or you may miss a payment.
What to do if you cannot pay your full bill on time
If you are struggling to pay, contact Mississippi Power before your due date. The company offers payment arrangements that let you split what you owe into smaller payments over time. Call customer service or log into your account to request an arrangement — most are set up for 30 to 90 days.
Mississippi Power also has programs for customers with low income or those facing hardship. Ask about budget billing, which spreads your annual costs evenly across 12 months so your bill is the same each month. This can help you plan ahead and avoid surprise high bills in summer or winter.
Understanding your bill before you pay
Before you pay, take a moment to check what you are being charged for. Your Mississippi Power bill shows your meter reading, the kilowatt-hours you used, the rate per kilowatt-hour, and any taxes or fees. If the usage seems too high, check whether you have been home more than usual or whether the bill covers a longer period than normal (some bills cover 32 or 33 days instead of 30).
If you spot an error or have questions about a charge, contact Mississippi Power before you pay. A representative can explain the charges or investigate if something looks wrong. Paying first and disputing later can complicate the process.
Keeping your account secure when you pay online
When you create an account at mississippipower.com, use a strong password that you do not use for other websites. If you pay as a guest without logging in, you will not need a password, but you will need to enter your account number and personal information. Either way, make sure you are on the official Mississippi Power website — check that the web address starts with "https://" and includes "mississippipower.com".
Do not share your account number or password with anyone, and do not pay through links in emails or texts unless you initiated the contact yourself. If you receive an email claiming to be from Mississippi Power asking you to verify your account, go directly to the website instead of clicking the link in the email.
Payment deadlines and late fees
Your due date is printed on your bill. If you pay after that date, Mississippi Power charges a late fee. The amount varies, but it is typically a percentage of your bill or a flat fee — check your bill or account for the exact amount. Paying online or by phone on the due date itself usually counts as on-time, but mail payments need extra time, so send them several days early.
If you miss a payment and receive a notice, contact Mississippi Power right away. The company may offer a grace period or a way to catch up before they disconnect your service. Staying in touch is important — ignoring notices makes it harder to work out a solution.
