Last year, we told you the copper line transition was coming. Now it’s no longer a future event. It’s happening.
In October 2025, AT&T stopped accepting new orders and most moves, adds, and changes for copper-based services across 18 states. That was the warning shot. What is happening now is the next phase of the retirement.
The New Deadline You Need to Know
Beginning in June 2026, AT&T started the first phase of retiring its legacy copper network in approximately 500 wire centers nationwide, representing about 10% of its wire center footprint. Businesses served by those wire centers are being migrated to fiber, fixed wireless, or other replacement technologies as copper services are discontinued.
This is more than a pricing change or a policy update. It marks the beginning of AT&T’s retirement of the underlying copper infrastructure in those approved wire centers.
Not every AT&T customer is affected today. Copper retirement is occurring wire center by wire center, so two buildings in the same city may have different timelines. The important question is whether your building is served by one of the approved retirement areas.
A wire center is the physical hub that connects copper lines in each area back to the network. Once a wire center retirement becomes effective for your service, affected copper lines are discontinued unless they have already been migrated to a replacement service. While AT&T offers replacement services such as fiber or wireless, where available, it does not automatically replace specialized life-safety connections such as elevator phones or fire alarm communicators. Those systems require their own migration plan.
AT&T has also received FCC approval to discontinue copper-based services affecting approximately 90,000 additional customers across 18 states beginning in November 2026. The company has publicly stated its goal of retiring nearly all of its legacy copper network by the end of 2029.
Don’t Wait for the Notice
Under current FCC rules, customers may receive as little as 90 days’ notice before certain copper services are discontinued, depending on the type of retirement and service involved. Even when additional notice is provided, organizations responsible for commercial buildings should assume they have far less time than they think once vendor selection, equipment procurement, installation, inspections, and testing are factored in.
Ninety days—or even six months—can disappear quickly. You need time to identify every system still using copper, evaluate replacement options, schedule installation, coordinate inspections, and verify that every life-safety system is operating properly before the retirement date arrives. For a single location, that may be manageable. For a portfolio of buildings, it quickly becomes a complex project.
The FCC has also streamlined the retirement process by reducing some of the regulatory review steps that previously slowed network retirements. That does not eliminate customer notice requirements, but it does mean there are fewer procedural delays once a carrier decides to retire a portion of its copper network. The protection you have is the notice period itself—not a lengthy approval process afterward.
Why This Isn’t Just an IT Problem
The equipment most exposed to copper retirement usually isn’t your business phone system. It’s your fire alarm panel, elevator emergency phone, security system, gate controller, building access system, and sometimes even a legacy fax line supporting business operations.
Elevator emergency phones are governed by ASME A17.1 and require a reliable two-way communication path as part of annual inspections. Many fire alarm panels still rely on a Digital Alarm Communicator Transmitter (DACT) to send signals to a central monitoring station over a copper telephone line. If that line is discontinued and no replacement has been installed, inspections can fail and critical life-safety systems may no longer communicate properly with monitoring services.
Depending on your local authority having jurisdiction, an inspection failure can result in citations, required corrective action, or even an elevator being removed from service until the issue is resolved. A failed fire alarm communication path is not simply an IT issue—it’s a life-safety and compliance issue.
Standard business VoIP service is also generally not an appropriate replacement for these applications. Life-safety equipment typically requires purpose-built communication solutions specifically designed, tested, and certified for elevator emergency phones, fire alarm communicators, and other critical systems.
What You Should Do Now
If your building is located in an area affected by the June 2026 wire center retirements—or if you simply don’t know whether it is—now is the time to find out. Waiting until you receive a discontinuance notice leaves very little time to evaluate options, coordinate vendors, and complete installations.
Start with a simple audit. Review your telecom bills and identify anything listed as analog, POTS, business line, or single-line service. Then walk your property and match those lines to the systems they support, including fire alarm panels, elevator phones, security systems, gate controllers, access control equipment, irrigation controllers, backup systems, and any other device connected to a traditional telephone jack.
Once you know what each line supports, you can determine the right migration strategy. A life-safety circuit deserves a very different replacement than an infrequently used fax line, and treating every copper line the same can lead to unnecessary costs—or unnecessary risk.
Where We Come In
We’re vendor-neutral, which means we’re not limited to recommending a single manufacturer’s solution or a single carrier’s service. We work with many providers to identify the replacement that best fits your building, compliance requirements, existing equipment, and budget.
If you’re not sure whether your property is served by one of the affected wire centers, we can help determine your exposure, identify every copper-dependent system in your building, and recommend the most appropriate migration strategy—all at no cost to you.
