Optimum Customer Service: 1-866-218-3259

Call to talk to a real-life person about your Optimum service today. You can also chat online, or find online resources.

Update: As of August 1, 2022, Suddenlink is officially becoming Optimum. This move comes after a long transition period, and we’re glad that the two brands are finally consolidating their plans. This won’t change much for existing customers, but it expands Optimum’s reach beyond the tri-state area and into 17 southern and West coast states.

Optimum customer service hours of operation

Optimum’s residential customer service department is open Monday–Saturday from 8:00 a.m.–6:00 p.m. eastern time.

Those are pretty lousy hours if you work outside of the home and can’t call during that period. Fortunately, there are other ways to contact Optimum support—and its tech support department is open all night. Read on for details.

Optimum outages

Is your internet out? Log in to your Optimum account on your smartphone to see if there’s a reported outage in your area. Optimum may already be working to resolve the issue.

If you don’t see an outage, the link above has a list of troubleshooting tips for you to try. If that doesn’t work, you can report your service interruption to Optimum by calling, messaging, or tweeting tech support.

Before you call Optimum

It never hurts to plan ahead for a customer service call. We humbly offer this checklist of things to have ready before you dial.

  • Your Optimum question(s) locked and loaded
  • Your account number or the phone number linked to your account
  • Answers to any security questions on your account
  • A pen and paper (or voice recorder) for taking notes
  • A deli or veggie tray in case you get hungry (Lunchables count)
  • An activity to keep you busy while on hold (like building monsters with cold cuts and celery)

Optimum customer service FAQ

Can I pay my Optimum bill in person?

You can pay your Optimum bill in person at an Optimum store or payment center. Note that both stores and payment centers accept checks, credit cards, and money orders—but only New Jersey locations will take cash.

Does Optimum have deals or promotions for business customers?

Optimum is offering a Visa prepaid gift card up to $100 on certain new business accounts for a limited time. Click here to learn about more Optimum deals.

How do I speak to an Optimum representative?

You can call the Optimum Customer Care department at 1-888-705-7171. The menu offers prompts in both English and Spanish.

Does Optimum offer discounts for seniors?

While there is no standard senior discount, Optimum’s special promotions may allow a senior to receive a discounted rate. Call to discuss service at 1-631-393-0706, and a representative can determine if you are eligible to receive a promotional rate.

What channel can I see my Optimum bill?

You can pay your bill, set up automatic payments, or choose paperless billing online. Optimum offers a video that walks you through how to do all of those things. You can also watch the video on Explore Optimum channel 900 and Explore Optimum en español on channel 904.

How do I pay my Optimum bill?

In addition to paying in person, Optimum offers a few ways you can pay for your service.

To pay online, sign in at and click Pay Bill at the top right-hand corner of the page. From there, you can view or pay your bill. If you haven’t created an account, this is a good place to start. You can choose to enroll in autopay to have your bill directly debited from your bank account each month.

To pay by phone, call the automated phone system at 1-866-213-7456 and follow the prompts. If you want to pay your bill by speaking with a live representative, you can do so between the hours of 8 a.m. and 8 p.m., but each call will cost you $10.

The Optimum Support App is another way you can pay your bill. Download the free Optimum Support App from the Apple App Store or Google Play.

You can also sign up for paperless billing online. Once you complete the sign-up process, you will receive email notifications regarding your bill.

Will Optimum buy out my contract?

If you are stuck in a contract, Optimum will give you $100 when you make the switch to their service. They won’t require you to sign a contract.
