AT&T POTS Line Shutdown: When the Copper Landline Phase-Out Hits You (2026 Timeline)
The AT&T POTS line shutdown has already begun. AT&T stopped accepting new copper landline orders on October 15, 2025, begins permanently decommissioning copper in roughly 500 wire centers in June 2026, and plans to retire the large majority of its copper network by the end of 2029. Existing customers are being moved to fiber, wireless, or VoIP — usually with about 12 months’ notice and the option to keep their number.
TL;DR — the AT&T copper landline phase-out at a glance
- Oct 15, 2025 — AT&T stopped taking new copper (POTS) orders and stopped processing moves, adds, and changes in affected areas.
- June 2026 — Physical decommissioning of copper begins in ~500 wire centers (about 10% of AT&T’s footprint).
- On/after March 15, 2027 — State-level discontinuance notices (e.g., Illinois) set hard end dates for legacy residential copper.
- End of 2029 — AT&T plans to retire the large majority of its copper network (California is excluded and contested).
- What to do — Inventory every device on the line, expect a notice letter (~12 months), choose a replacement, and port your number before your area is cut over.
What is POTS, and why is AT&T shutting it down?
POTS (Plain Old Telephone Service) is the traditional analog landline that runs over AT&T’s copper wires. AT&T is retiring it because the copper network is aging, expensive to maintain, and serves a shrinking base of customers while the company shifts investment to fiber and 5G wireless.
Definition: POTS / copper landline. POTS is the standard analog voice line that has powered home and business phones for over a century. It draws power from the phone company’s copper line, so it keeps working during a power outage. Many non-phone systems — fire alarm panels, elevator emergency phones, security and medical-alert devices, fax machines, and some point-of-sale and SCADA equipment — were built to run on a POTS line, which is why the shutdown reaches far beyond home phones.
Three things are driving the AT&T copper retirement: cost (century-old copper is far more expensive per line than fiber or wireless), strategy (AT&T is concentrating capital on higher-margin fiber and 5G), and regulation — in March 2026 the FCC streamlined the rules for retiring copper, clearing the runway for the 2026–2029 shutdown.
AT&T POTS line shutdown timeline: the key dates
It is not a single switch-off date — it rolls out region by region in phases. Here is the national timeline:
- October 15, 2025 — Orders frozen. AT&T stopped accepting new POTS orders and stopped processing moves, adds, or changes across thousands of wire centers in roughly 19 states.
- December 2025 — First approvals. The FCC approved AT&T to discontinue service at wire centers covering about 90,000 customers across 18 states — more than 30% of its copper footprint outside California.
- June 2026 — Decommissioning begins. AT&T starts physically dismantling copper in roughly 500 wire centers nationwide (about 10% of its footprint). Once a wire center is decommissioned, copper service there ends permanently.
- On/after March 15, 2027 — State end dates. Discontinuance letters in states such as Illinois tell residential copper customers their service will end on or after this date.
- End of 2029 — Large-majority retirement. AT&T plans to retire the large majority of its copper network outside California by the end of 2029. California copper is excluded and is the subject of a separate legal and regulatory fight.
Scale & revenue impact. Industry analysts (Metrigy) estimate AT&T still carries on the order of 600,000 active POTS lines across residential and business customers — a small slice of the 40-million-plus POTS lines the FCC counts nationwide. POTS is a low-revenue service for AT&T (2025 revenue was about $125.6 billion), so copper voice is a minor, declining piece of the business — one reason the retirement is moving quickly.
Who is affected by the AT&T copper retirement?
Anyone in AT&T’s copper footprint who still relies on an analog line — residential or commercial. The risk is not just losing a home phone; it is losing service on any device wired to that line. Affected systems include:
- Home and business fire alarm panels and burglar/security alarms
- Elevator emergency phones (required by code to call out)
- Medical-alert and personal-emergency-response devices
- Fax machines, modems, and analog telemetry
- Point-of-sale terminals, gate/access systems, and some SCADA equipment
How will you know your line is being shut down?
AT&T notifies affected customers by mail. Customers typically receive about 12 months of notice before service in their area ends, and many areas get more than one letter. In Illinois, for example, letters went out in late 2025 and again in March 2026 with a March 15, 2027 end date. If you get one of these letters, it is real — do not ignore it, and do not wait until the final month to switch. Consumer advocates such as the Citizens Utility Board note that AT&T is generally not supposed to strand customers who have no alternative service — but the safest move is to confirm your options early.
What are your replacement options?
You have four realistic paths off copper. The right one depends on whether you mainly need a home phone or you have analog equipment (alarms, elevator, fax) that must keep working.
| Option | Best for | How it works | Keeps your number? |
|---|---|---|---|
| Fiber / AT&T Internet voice | Homes & offices where AT&T Fiber is available | Digital voice carried over your fiber broadband connection | Yes — number porting supported |
| AT&T Phone Advanced (VAB-1 “POTS in a Box”) | Keeping existing analog phones, fax, alarms, elevators | On-site gateway with FXS ports; runs over broadband or LTE with cellular failover and 24-hour battery backup (NFPA 72) | Yes |
| Wireless home phone / cellular | Basic home phone where there’s no fiber | A wireless base unit on AT&T’s cellular network with a standard phone jack | Usually |
| Third-party VoIP / POTS replacement (e.g., POTS Link) | Businesses wanting multi-carrier redundancy | Managed analog-to-IP service; some use tri-carrier SIMs (AT&T, Verizon, T-Mobile) for failover | Yes |
Note on life-safety devices: fire alarm panels and elevator phones have code requirements (such as 24-hour backup power under NFPA 72). If you have these, pick a replacement built for them — AT&T Phone Advanced and dedicated POTS-replacement services are designed for this; a basic consumer wireless phone may not be.
What should you do right now?
Whether you are a homeowner with one landline or a business with a dozen analog circuits, the same five steps apply:
- Inventory every device on each copper line — phones, alarms, elevators, fax, medical alerts, POS, gates.
- Watch your mail for an AT&T discontinuance letter and note the end date for your area.
- Check what’s available at your address — AT&T Fiber, wireless, or a POTS-replacement device.
- Choose a replacement that supports your life-safety and analog equipment, not just voice.
- Schedule the cutover and port your number before the copper end date so you avoid a service gap.
To explore digital voice or wireless replacements for your specific location, start at the AT&T Support Center.

Frequently asked questions about the AT&T POTS line shutdown
Is my AT&T landline being shut off in 2026?
Possibly, if you’re in one of the ~500 wire centers AT&T begins decommissioning in June 2026. Most customers get about 12 months’ written notice before their area’s copper line ends, so check your mail and confirm your end date with AT&T.
Will the AT&T POTS shutdown affect my home alarm or medical-alert device?
Yes, if that device runs on a copper line. Fire alarms, burglar alarms, elevator phones, and many medical-alert units were built for POTS and must be moved to a digital or wireless replacement, or they will stop communicating once copper is retired.
Can I keep my phone number?
In almost all cases, yes. AT&T Phone Advanced, fiber voice, wireless home phone, and third-party POTS-replacement services all support porting your existing number, so you can switch off copper without changing your phone number.
Does the AT&T copper shutdown affect California?
California is excluded from the end-of-2029 target and is being handled separately. AT&T has pursued legal and regulatory action to be allowed to retire California copper, but those lines are not part of the main nationwide phase-out timeline.
What if I have no fiber or cell signal at my address?
Tell AT&T before your end date. Providers generally aren’t supposed to strand customers who have no adequate alternative, and a cellular-based POTS-replacement device with an external antenna or a satellite/VoIP option may be available. Confirm coverage early rather than assuming it exists.
