The copper shutoff, explained
Traditional phone lines are being retired, and anything still on one needs a plan.
What is actually being switched off?
The copper network that carries traditional phone lines — the ones often called POTS. Providers are retiring it region by region as the equipment reaches end of life. There is no single national switch-off date, and no federal deadline that applies to you as the customer. Instead, lines are withdrawn area by area, on notice, and prices on what remains keep climbing. Retiring copper is a regulated step: the incumbent provider generally needs FCC authorization to discontinue the service and has to give advance notice, and the FCC streamlined parts of that process in 2026. So the practical warning you get depends on your provider and your area rather than on one fixed rule.
How it reaches you
Prices rise first
Line rental on remaining copper has been increasing for years. This is usually the first signal a business notices.
Repairs get slower
Spares and technicians for a retiring network thin out. A fault that once took a day can take a week.
New lines stop being sold
In many areas you can no longer order copper at all, even where existing lines still work.
A notice arrives
Your provider writes with a date after which the line stops. The FCC’s rules have generally required at least 90 days’ notice to residential customers and at least 180 days to business customers before a copper retirement. The date and the window in your own letter are the ones that govern.
The line is disconnected
Anything still depending on it stops working at that point.
What is usually still on copper
| What | Why it matters | Typical replacement |
|---|---|---|
| Elevator emergency phone | Required by code, and people get trapped | A cellular unit approved by your elevator company |
| Fire alarm panel | Governed by code and by your insurer | Cellular or dual-path reporting, specified by the fire contractor |
| Burglar alarm | Downgrades to local-only if the line dies | Internet or cellular reporting on the existing panel |
| Fax | Still required by some trades and clients | A digital fax service that emails the pages |
| Gate, door and intercom | Access stops working | An IP intercom, or a cellular adapter on the old one |
| Modems, dial-up terminals, old alarms | Often forgotten entirely | Usually a network replacement, sometimes nothing |
| Backup line for the office | Rarely used and rarely missed | Mobile, or nothing |
What to do now
- Find every copper line on your bills, including ones with no calls on them
- Walk the building and identify what is physically connected to each
- Ask your elevator, fire and alarm companies what they support and what your code requires — this is their decision, not yours
- Replace the easy ones early: fax, unused lines, spare handsets
- Keep the numbers. A copper line being retired does not mean the number has to go with it — see keeping your phone numbers
- Do the whole audit at once, using analog lines
A note on analog adapters
An adapter that puts a copper handset onto your internet connection is a genuine answer for a spare phone or a fax machine. It is generally not an answer for an elevator phone or a fire panel: those need to work when your network and your power do not, and what is acceptable is set by code and by the company that maintains the equipment, not by what happens to work on a test call.
What waiting costs you
Every part of a copper replacement gets harder under a deadline. Technicians get booked, inspections take time, and a rushed decision on a fire panel is the wrong kind of saving. Businesses that plan the change get to choose the replacement; businesses that wait get whatever is available in the window they have left.
