AT&T copper retirement, market by market.
Has stated it intends to exit copper in the majority of its wireline footprint by the end of 2029, with customer upgrades and legacy-service discontinuation underway in portions of its footprint since summer 2026.
Below is what Critical Line currently tracks from AT&T's own public network-disclosure filings: how many notices, which states they name, when the earliest effective dates fall, and a link to each original document.

What we track for AT&T right now.
Counted from AT&T’s own public network disclosures. Timelines vary by service and location, and a filing can be amended or withdrawn.
What this does, and does not, mean.
Carrier transition activity detected in or relevant to this market.
This does not by itself establish that your specific line will be disconnected. A Critical Line Assessment can verify the service and dependency.
Network-change and copper-retirement filings are not the same thing as a service-discontinuance event. What a filing does establish is that the window to identify your dependencies is closing.
AT&T publishes this activity as filing documents. Where our source terms permit a link but not a restatement, we show the facts and the official document instead of a paraphrase we cannot stand behind.
- 01Which carriers serve each property, and on what services
- 02Whether any notice names your state, market or wire center
- 03Which critical endpoints ride on the affected services
- 04What deadlines, inspections or rate changes are attached
- 05Which migrations need to happen first, and who must be involved
AT&T notices by state.
A state appears here because at least one AT&T filing names it. The date column is the soonest effective date still ahead of us in that state, taken from the filing itself.
A further 1 AT&T filing names a footprint or facility rather than a single state, so it is counted in the totals above but cannot be placed on this table.
Most recent AT&T filings.
Each entry links to the original document on the carrier’s own disclosure site. Where our source terms allow a link but not a restatement, we publish the facts and the link, and nothing else.
