A note on which company this is

CenturyLink's residential fiber service now operates under the Quantum Fiber brand, which is owned by AT&T (acquired from Lumen Technologies). The current subscriber agreement is titled "Quantum Fiber From AT&T Internet Subscriber Agreement." The figures below describe Quantum Fiber Internet specifically. If you have legacy CenturyLink copper/DSL or regulated landline phone service, different, older terms and state utility protections may apply. See the landline section below.

Late fee

Quantum Fiber Internet does not publish a late-fee dollar amount, a grace period, or a day count for a late fee. Its current subscriber agreement never uses the words "late fee," "late charge," "past due," or "delinquent." Quantum Fiber Internet is a prepaid service. You set up automatic monthly payments in advance rather than being billed and given time to pay afterward.

What the agreement does publish is a rule for a declined payment, not a late fee:

"If your payment method is declined, your Service will be suspended after 3 days. Once you update your payment method with us, we will reactivate your Service. The day we reactivate your Service will be your new payment date going forward."

Suspension timeline

Quantum Fiber Internet's subscriber agreement publishes one concrete timing rule for non-payment:

  1. Payment method declined: Service is suspended after 3 days
    • Quantum Fiber's account FAQ gives the notices along the way: "If your payment fails for any reason, you will get an email on the day your payment is due. If payment is not received, a follow-up email will be sent after 24 hours." Then: "If no action is taken within 48 hours from the payment due date, you'll receive a notice of service suspension for nonpayment."[2]
  2. Payment method updated and charge succeeds: Service is reactivated, and that day becomes your new monthly payment date going forward

No other suspension, disconnection, or collections day count is published in the agreement. Because Quantum Fiber Internet is prepaid, this 3-day window is much shorter than the ~25–45 day figures this page previously published, which came from CenturyLink's legacy postpaid billing and do not apply to the current Quantum Fiber product.

Reconnection fee

Quantum Fiber's agreement does not name a reconnection fee. Suspended service is restored automatically once you update your payment method and the payment succeeds. See Suspension timeline above.

Credit reporting

What CenturyLink (Quantum Fiber) says: Quantum Fiber's Internet Subscriber Agreement covers collection costs ("If we use a collection agency or initiate any legal action to recover amounts due, you agree to reimburse us") but doesn't say whether it reports accounts to credit bureaus.[1]

What federal law actually sets

Reporting to the credit bureaus is optional. The CFPB puts it plainly: "Reporting to credit bureaus and other consumer reporting agencies by creditors is voluntary and historically has been. Not all creditors report information about their borrowers."[3]: p. 15 The Fair Credit Reporting Act's rules for the companies that do report cover accuracy, disputes and dates. They don't set a minimum number of days late before an account can be reported.[4]: (a)

The "30 days late" figure you see everywhere comes from the data format, not from a law. Most furnishers send data to the bureaus in Metro 2, which reports "the level of delinquency such as 30-59 days past due, 60-89 days past due, and up to 180 days or more past due."[3]: pp. 3, 16 Experian's list of payment-status codes has no code for anything less than 30 days late: the late codes start at "Account 30 days past due date" and go up in 30-day steps to 180.[5] So a payment 10 or 20 days late has no late code to be reported under, though a late fee can still apply.

A third-party debt collector can't report a debt until it has either spoken to you about it in person or by phone, or mailed or electronically sent you a message about it and waited "a reasonable period of time to receive a notice of undeliverability."[6]: (a)(1)

Charge-off

A charge-off is the lender writing the balance off its books as a loss. It isn't the lender giving up: the federal bank policy that sets charge-off timing says the write-off "does not mean that the asset has absolutely no recovery or salvage value."[7] That policy also sets the timing, for banks and thrifts only: "Closed-end retail loans that become past due 120 cumulative days and open-end retail loans that become past due 180 cumulative days from the contractual due date should be classified loss and charged off." Closed-end means a loan with a fixed schedule, such as an installment loan; open-end means a revolving line, such as a credit card. Credit unions are outside it. Their regulator, the NCUA, "does not plan to adopt the Uniform Policy at this time."[8] It doesn't apply to phone, cable, streaming, insurance or utility companies either, because none of them is a bank. When one of those companies writes off a balance, the timing is its own.

How long it can stay on a report

For an account placed for collection or charged off, the Fair Credit Reporting Act's seven-year limit doesn't start on the day you fell behind. It starts 180 days later: the seven years begin "upon the expiration of the 180-day period beginning on the date of the commencement of the delinquency which immediately preceded the collection activity, charge to profit and loss, or similar action."[9]: (c)(1) That makes it about seven and a half years from the first missed payment. Paying the balance later doesn't restart or shorten that clock. Whoever reports a collection or charge-off must also tell the bureau "the month and year of the commencement of the delinquency", within 90 days of reporting it, and a collector who later reports the same account complies by reporting "the same date of delinquency as that provided by the creditor".[4]: (a)(5) A late payment that never goes to collection or charge-off falls under a separate catch-all, "any other adverse item of information", which also runs seven years but names no start date.[9]: (a)(5)

Direct reporting vs. collections

A company can report an account it still owns, or it can hand or sell the account to a collection agency, which then reports under its own name. The two can show up as separate items on your report for the same bill, and "consumers generally are not required to be notified when debt is sold or assigned to a collection agency."[3]: p. 30 Which of the two you're dealing with decides which rights apply. The Fair Debt Collection Practices Act covers people collecting debts owed to someone else, and it excludes a creditor's own staff "while, in the name of the creditor, collecting debts for such creditor." A creditor that collects under a different name is covered, though: the law "includes any creditor who, in the process of collecting his own debts, uses any name other than his own which would indicate that a third person is collecting or attempting to collect such debts."[10]: (6)

If the account reaches collections

A debt collector must send you validation information (what you owe, to whom, and how to dispute it) in its first communication or "within five days of that initial communication".[11]: (a)(1) If you dispute the debt in writing within 30 days, the collector "shall cease collection of the debt, or any disputed portion thereof, until the debt collector obtains verification of the debt" and mails it to you.[12]: (b) Disputing the credit report itself is a separate process. A bureau that gets your dispute must, "free of charge, conduct a reasonable reinvestigation" within 30 days (up to 45 if you send more information during that time),[13]: (a)(1) and the company that reported the item must investigate and then modify, delete or block anything it finds inaccurate, incomplete or unverifiable.[4]: (b)

Phone, cable and utility accounts

Phone, pay-TV and utility companies can also share your account history with a separate reporting company, the National Consumer Telecom & Utilities Exchange (NCTUE). According to the CFPB, it "collects and shares information on new telecom and utility connect requests, paid-as-agreed and past-due account and payment histories including delinquencies and charge-offs." Equifax runs the database for its members, but "Equifax is not a member of the NCTUE," and you can ask the NCTUE for a free copy of your report every 12 months.[14] Whether a particular provider reports to the NCTUE, to the three big bureaus, to both or to neither is up to that provider.

This section describes federal law and industry practice in general terms. It doesn't cover state law, which can add protections, and it isn't legal advice. It describes a company's own policy only where that company is quoted above. See the disclaimer.

Landline phone service protections

If you have CenturyLink's regulated landline service, some states require utility-style notices and longer grace periods before disconnection, especially for households with elderly or medically vulnerable members. Check your state's public utilities commission for specific protections.

Frequently asked questions

Will my Quantum Fiber service be disconnected the same way as CenturyLink DSL? No. Quantum Fiber Internet is prepaid and, per its subscriber agreement, suspends 3 days after a declined payment. Legacy CenturyLink DSL and landline service is billed differently and is regulated as a utility in some states, with longer notice periods. Check your specific service agreement.

Does CenturyLink offer a payment arrangement? Yes. CenturyLink customer service can set up a payment arrangement that splits a past-due balance into smaller installments and may delay disconnection.

Can my CenturyLink landline be disconnected in winter? Some states protect telephone service from disconnection during winter months, particularly for vulnerable households. Check your state's public utilities commission for state-specific rules.
