Is CenturyLink Going Out of Business? What Business Customers Need to Know

For many businesses, CenturyLink is still the name on the phone bill, even though the headlines now say Lumen. Between Lumen’s voice end of sale and AT&T’s purchase of Lumen’s consumer fiber business, it’s easy to see why so many customers are asking: is CenturyLink going out of business? It isn’t. This guide is written for business voice customers, and it answers the questions we hear most: Is CenturyLink still in business? Is CenturyLink now Lumen? Did AT&T buy CenturyLink? Is Lumen getting out of voice?

Quick Answer

Is CenturyLink going out of business? No.

CenturyLink remains a brand and a set of legal entities, including CenturyLink Communications LLC and CenturyLink QC, under Lumen Technologies, the name CenturyLink adopted in 2020.

Did AT&T buy CenturyLink? No.

In February 2026, AT&T bought Lumen’s consumer fiber business, not the business services companies contract for. Is Lumen getting out of voice? Partly: as of August 1, 2026, Lumen stopped selling and renewing business voice, but existing service keeps running and stays supported, and no shutdown date has been announced.

Why People Are Asking If CenturyLink Is Going Out of Business

Three things happened close together, and each one sounds more final than it is.

First, the name changed. CenturyLink became a part of Lumen Technologies in 2020, so the CenturyLink brand many businesses know is now rarely in the news. Second, Lumen sold its consumer fiber business to AT&T, which made headlines about Lumen customers moving to another carrier. Third, Lumen put its business voice services, including CenturyLink voice, into end of sale, which left many customers asking: is Lumen getting out of voice, and is CenturyLink going with it?

On top of that, carriers across the industry are retiring copper phone lines. A copper retirement notice in your area can easily read like CenturyLink closing up shop, when it’s really a change in the underlying technology. So is CenturyLink still in business? Yes, and the sections below explain why.

Is CenturyLink Still in Business?

Yes. CenturyLink continues as a brand and as legal entities, including CenturyLink Communications LLC and CenturyLink QC, operating under Lumen. Those are the names you’ll still see on invoices and service agreements. Your CenturyLink service hasn’t been shut off, and customers with a CenturyLink agreement receive full support today.

Is CenturyLink Now Lumen?

Yes. CenturyLink is the brand; Lumen Technologies is the parent company. CenturyLink grew over roughly two decades by acquiring regional phone companies, and the CenturyLink legal entities from those deals carried forward rather than being retired. Here’s the whole chain:

So is CenturyLink now Lumen? For your contract, yes. That history is also why one business can see Lumen, CenturyLink Communications, Qwest Corporation, or Level 3 Communications on different paperwork. Our guides to Qwest Corporation and Level 3 Communications cover those branches.

Did AT&T Buy CenturyLink?

No, but the confusion is understandable, and it’s a big part of why “did AT&T buy CenturyLink” has become one of the most searched questions about the company. On February 2, 2026, AT&T completed a $5.75 billion purchase of Lumen’s Mass Markets fiber business, the consumer side that included the Quantum Fiber brand and about a million home internet subscribers.

What AT&T bought was residential fiber. CenturyLink as a company, and the business services Lumen sells to companies, including voice, stayed with Lumen. If you’re a business customer with a CenturyLink contract, your agreement is still with a CenturyLink or Lumen entity, exactly as before.

Is Lumen Getting Out of Voice?

For new sales, yes. As of August 1, 2026, Lumen stopped selling and renewing business voice services, including for accounts under CenturyLink Communications LLC, CenturyLink QC, and other CenturyLink entities. This is the CenturyLink voice end of sale, and it covers SIP trunking, Voice Complete, Microsoft Teams voice services, and Zoom voice services sold through Lumen.

For existing customers, not today. End of sale isn’t end of service. Your current agreement keeps running under its existing terms, support continues, and no shutdown date has been announced. Our Lumen voice end of sale guide covers the full detail.

How to Verify Service Status and Official Announcements

When a headline worries you, go to the source:

1. Check Lumen’s newsroom and investor relations pages for official announcements, and its SEC filings for anything material.
2. Look for FCC discontinuance or copper retirement notices in your area, which carriers are required to file publicly.
3. Review your own account. Your invoice and master service agreement show which entity you contract with, often CenturyLink Communications LLC or CenturyLink QC, and your term end date. Our Is my voice contract affected? check walks you through it.
4. Ask for it in writing. If you’re unsure, ask your account team to confirm any change to your service in writing, and keep every notice you receive.

What This Means for Business Voice Customers

If CenturyLink Communications LLC, CenturyLink QC, or simply CenturyLink is the name on your bill, the CenturyLink voice end of sale affects you, but nothing is urgent. Your service is running today and isn’t scheduled to stop. What changes is what happens at the end of your term: there’s no new voice contract to renew into, so service typically converts to month-to-month, which usually costs more.

The useful next step is finding your term end date and deciding, on your own schedule, what comes next. Common paths include another carrier’s SIP trunking (see our PRI to SIP migration guide), a cloud platform like Microsoft Teams Phone or Zoom Phone, or replacing any remaining analog lines (see our POTS line replacement guide).
