☎️ The End of an Era: AT&T’s Landline Service Set to Retire

Listen

The era of the traditional copper-based telephone landline, known as Plain Old Telephone Service (POTS), is rapidly coming to a close for many AT&T customers. The telecommunications giant is actively working to retire the vast majority of its legacy copper network across its service areas in a multi-year transition, with a nationwide target completion date set for the end of 2029.

This shift marks a significant move away from century-old infrastructure. The company has cited the outdated nature of the copper network—its vulnerability to theft, water damage, and high maintenance costs—as the driving forces behind the decision. Company executives have noted that only about 5% of their residential customers still rely on copper landline technology, making its maintenance fiscally unsustainable. Phasing out the copper network is expected to save the company a substantial percentage of its maintenance budget.

The transition process has already begun. As of October 15, 2025, AT&T has stopped accepting new orders or modifications for traditional copper landline service in affected wire centers across many states. Furthermore, specific discontinuation dates are being announced region by region, with some existing customers receiving notices that their service will be terminated on or after March 15, 2027, depending on location and regulatory approval.

Alternatives and Concerns

The phase-out, however, presents a challenge for the remaining customers, especially those in rural areas or those who rely on landlines for essential services. Traditional copper landlines famously remain functional during power outages, as they do not require an external power source. In contrast, the modern replacements—Voice over Internet Protocol (VoIP) and cellular-based alternatives—require battery backup to operate during a power loss.

AT&T is directing customers to modern alternatives such as fiber-optic connections or a wireless solution called AT&T Phone – Advanced (AP-A), which uses a cellular network. This new technology is designed to connect to a customer’s existing in-home wiring, allowing them to keep their current phones, fax machines, and medical devices that rely on the connection.

Regulators in several states have raised concerns about the potential impact on public safety, especially for the elderly, residents in rural areas with spotty cell service, and those who use landlines for medical monitoring or security systems. State utility commissions and attorney general offices are working to ensure that AT&T provides a reliable alternative service and maintains access to 911 for all customers before any permanent disconnection. AT&T is required to obtain approval from the Federal Communications Commission (FCC) before fully discontinuing landline service in an area.

Customers who are still using a traditional copper landline are advised to contact AT&T to discuss their alternative options and the specific timeline for their location. Ignoring the notices could lead to a loss of service for critical communications and essential third-party systems.
