The main Optimum customer service number is 1-888-652-2666
Call this number to pay your Optimum bill over the phone. A representative will walk you through payment options, take your account number, and process the payment while you're on the line. The call typically takes 5 to 10 minutes. Have your bill or account number ready before you dial.
Optimum's phone lines are open Monday through Friday, 8 a.m. to 8 p.m. Eastern Time, and Saturday and Sunday, 9 a.m. to 5 p.m. Eastern Time. Wait times vary depending on the time of day and how busy the network is. Calling early in the morning or mid-week usually means shorter holds.
If you're calling from outside Canada, you may face long-distance charges. Check your phone plan before calling from a mobile device, or use a landline if available.

What payment methods Optimum accepts over the phone
When you call to pay, have one of these ready: a Visa or Mastercard credit card, a debit card, or your bank account information for a direct debit. Optimum does not accept American Express or Discover cards by phone, though you may be able to use them on the website.
If you're paying from a bank account, the representative will ask for your transit number, institution number, and account number. This information is on the bottom left of your cheques. The payment will be processed as a one-time debit and typically clears within one to three business days.
Alternatives to calling if you want to avoid the phone
You can pay your Optimum bill online through your account on the Optimum website without speaking to anyone. Log in with your email and password, go to the billing section, and choose your payment method. Online payments process the same day and are often faster than calling.
You can also set up automatic payments so your bill is paid on the same date each month without you having to do anything. This removes the step of calling or logging in each time. To set this up, call the same number (1-888-652-2666) and ask a representative to configure automatic payments on your account.
If you receive a paper bill in the mail, you can pay by cheque and mail it to the address printed on the bill. Cheques take longer to process — usually 5 to 10 business days — so use this method only if you're not close to your due date.
What happens if you call after business hours
If you call outside Optimum's customer service hours, you'll reach an automated system. The system can take payment information, but you won't speak to a person. You can leave a message, and a representative will call you back during business hours, though this delays your payment.
For faster service outside regular hours, use the online payment option on the Optimum website. Online payments are available 24 hours a day, 7 days a week, and process immediately.
How to find your account number before you call
Your Optimum account number appears on your bill, usually near the top or in the account information section. If you don't have a recent bill, log into your Optimum account online and look for the account number in your profile or billing details.
If you can't locate your account number, you can still call 1-888-652-2666 and provide your phone number or address instead. The representative will look up your account and confirm your details before processing the payment.
Payment timing and when the money leaves your account
When you pay by phone with a credit or debit card, the charge appears on your card statement immediately, though the actual transfer of funds may take one to three business days depending on your bank. When you pay from a bank account, the debit is processed within one to three business days.
Your Optimum bill is considered paid as soon as the representative confirms the payment over the phone. If you're paying close to your due date, call at least three business days before the deadline to ensure the payment clears in time and you avoid a late fee.
Frequently Asked Questions
Can I pay my Optimum bill without calling?

What if I don't have my account number when I call?
You can provide your phone number or the address on your account instead. The representative will look up your account using this information and confirm your details before taking payment.
Does Optimum charge a fee to pay by phone?
Optimum does not charge a fee for phone payments. However, if you use a credit card, your credit card company may charge a cash advance fee depending on your card agreement. Check with your card issuer before paying with credit.
How long does a phone payment take to show on my bill?
Phone payments are recorded on your account immediately after the representative confirms the transaction. However, the actual funds may take one to three business days to transfer from your bank or card, depending on your financial institution.
Can I pay someone else's Optimum bill by calling this number?
You can pay if you have the account number and the account holder's permission. The representative may ask security questions to verify you're authorized to make the payment. If the account is in someone else's name, it's safer to have them call and authorize the payment themselves.
