Call Optimum customer service at 1-866-200-9111 to pay your bill over the phone
The fastest way to pay an Optimum bill by phone is to call their automated payment line at 1-866-200-9111. You will need your account number (found on your bill or in the My Optimum app) and a debit card or credit card ready. The system accepts Visa, Mastercard, American Express, and Discover. The call takes about five minutes, and your payment posts within one business day.
If you prefer to speak with a representative instead of using the automated system, you can stay on the line after calling the same number and press the option for a live agent. Wait times vary depending on the time of day and how busy the customer service team is. Calling early in the morning on a weekday typically means shorter waits than calling in the evening or on weekends.
Optimum does not charge a fee to pay by phone with a debit card. If you use a credit card, Optimum treats it as a cash advance, which means your credit card company may charge you a fee — check with your card issuer before paying this way.

What information you need before calling
Gather these details before you dial so the call moves quickly. You will need your Optimum account number, which appears on your paper bill or in the My Optimum app under Account. If you do not have your bill handy, you can look up your account number by logging into My Optimum online or on your phone.
Have your payment card ready — the debit or credit card you want to charge the payment to. The system will ask for the card number, expiration date, and the three-digit security code on the back. If you are paying someone else's bill (a family member or roommate), you will still need that person's account number, but you can use your own card to pay.
Know the amount you want to pay. You can pay your full bill balance, a partial amount, or just the minimum due. The system will tell you what you currently owe before asking how much to pay, so you can decide in the moment.
When your payment will show up in your account
Payments made by phone typically post within one business day. This means if you pay on a Monday, the payment usually shows by Tuesday. If you pay on a Friday evening or over the weekend, expect it to show by Monday or Tuesday. Business days do not include Saturdays, Sundays, or federal holidays.
If you are paying because you are behind on your bill or facing a service suspension, call as early in the day as possible. Optimum processes payments throughout the day, and calling early gives the payment the best chance of posting before any automated suspension occurs. If your service has already been shut off, paying by phone will restart it, but there may be a reconnection fee — ask the representative about this when you call.
Other ways to pay without calling
If you prefer not to call, you can pay online through the My Optimum app or the Optimum website. Log in with your account number and password, go to the billing section, and select "Pay Now." The online system accepts the same cards as the phone line and posts payments just as quickly.
You can also set up automatic payments through the My Optimum app so your bill is paid on the same day each month without you having to remember. This option works with a debit card or bank account. Automatic payments mean you will never miss a due date, though you can pause or cancel them anytime if your situation changes.
Some Optimum customers receive paper bills and prefer to pay by mail. You can send a check to the address on your bill, but mail payments take longer to post — typically one to two weeks depending on mail delivery time and Optimum's processing speed. Paying by phone or online is faster if you need the payment to show quickly.
What to do if the payment line is busy or not working
If you call 1-866-200-9111 and the automated system is not responding or you get a busy signal, try again in a few minutes. Optimum's phone lines occasionally experience high volume, especially on bill due dates or during outages. Calling at an off-peak time — early morning or mid-afternoon on a weekday — usually works better.
If the phone line remains unavailable, use the My Optimum app or website to pay instead. Both are usually available even when phone lines are congested. You can also visit an Optimum retail store in person if one is near you, though this takes more time than calling or paying online.
Fees and things to know about paying by phone
Optimum does not charge you a fee to pay your bill by phone with a debit card. However, if you use a credit card, your credit card company may charge a cash advance fee because Optimum treats credit card payments as cash advances rather than regular purchases. This fee is typically 3 to 5 percent of the payment amount, depending on your card. Check your credit card's terms or call your card issuer before paying with a credit card to avoid a surprise charge.
If you are paying a past-due bill, the representative can tell you whether any late fees have been added to your balance. Late fees vary and depend on how long your account has been overdue. Paying as soon as you can stops additional late fees from accumulating.
Optimum does not offer a discount for paying by phone versus other methods. The payment amount is the same whether you call, pay online, or pay in person.
Frequently Asked Questions
Can I pay someone else's Optimum bill by phone?
Yes. You will need the account number of the person whose bill you are paying, but you can use your own debit or credit card. The payment will post to their account, and they will see it reflected on their next bill or in their online account.
What if I want to pay only part of my bill?
The automated system lets you enter any amount you want to pay, not just the full balance. You can pay the minimum due, a partial amount, or the entire bill. Just tell the system how much when it asks.
Is there a limit to how much I can pay by phone?
Optimum does not publish a specific limit, but most payment systems cap single transactions at $10,000 to $25,000 depending on your card. If your bill is larger than this, ask the representative to split the payment across two transactions or to discuss other payment options.
Do I get a confirmation number when I pay by phone?
Yes. The automated system will give you a confirmation number at the end of the call. Write it down or take a screenshot. Keep this number in case you need to reference the payment later or if there is a dispute about whether the payment went through.
What time can I call to pay my bill?
The automated payment line is available 24 hours a day, 7 days a week. If you want to speak with a live representative, customer service hours are typically Monday through Friday, 8 a.m. to 9 p.m., and Saturday and Sunday, 9 a.m. to 6 p.m., though hours may vary by location.
