Received a POTS line price increase notice? Here’s what it means.

Publish Date: September 17, 2026

Key Points:

  • POTS line price increases reflect the broader transition away from aging copper telephone networks.
  • Before replacing a line, identify the equipment it supports.
  • Auditing affected lines now can uncover unused services, control rising costs, and support a planned migration.

If you’ve received a letter from your telephone carrier announcing a price increase for your POTS lines, you’re not alone.

Businesses across the country are seeing substantial increases on legacy copper telephone service. While the amount varies by carrier and market, the message is the same: the cost of maintaining copper lines is rising, and carriers are increasingly passing those costs on to the customers who remain.

If you received one of these notices, here are the five questions you should be asking.

Why did I get this notice?

You’re receiving this notice because your carrier has increased the price of your legacy copper telephone service.

For decades, regulators oversaw POTS line pricing. Today, carriers have more flexibility to price legacy copper services, and many have raised rates as they retire aging copper infrastructure and support a shrinking customer base.

The notice isn’t a billing error or an account-specific issue. It’s part of a broader industry transition away from copper networks.

Can I negotiate or appeal it?

In most cases, no.

Price increase notices generally apply to entire service offerings, not individual customer accounts. While it’s always worth discussing your options with your carrier, most organizations find that the new pricing applies across their market or service area.

Rather than focusing on negotiating the increase, it’s usually more productive to evaluate whether the affected lines are still necessary and whether more cost-effective alternatives exist.

Will my rates keep increasing?

They may.

Many businesses have experienced multiple increases over the past several years as carriers continue reducing investment in legacy copper networks.

The exact timing and amount of future increases will vary, but organizations should plan with the expectation that copper service is unlikely to become less expensive over time.

Should I keep paying or replace the line?

That depends on what the line supports.

If the line serves an active business phone, replacement may be straightforward.

If it supports a fire alarm panel, elevator emergency phone, security system, building entry system, fax machine, or other critical equipment, replacing it requires more planning.

The first step isn’t choosing a replacement service.

It’s understanding exactly what each line is connected to.

Many organizations discover that copper lines installed years ago still support critical systems they didn’t realize were dependent on traditional telephone service.

What should I do today?

Don’t wait for the next increase.

Start by reviewing every line identified in the notice.

Ask yourself:

  • Which phone numbers are affected?
  • What device or system does each line support?
  • Are any lines no longer being used?
  • Which systems have compliance or life-safety requirements?
  • What will these lines cost over the next 12 to 24 months if we do nothing?

Once you understand what each line supports, you can build a migration plan based on business priority instead of reacting under pressure later.

The bottom line

A POTS price increase notice isn’t just telling you your monthly bill is going up.

It’s telling you that legacy copper service is becoming increasingly expensive to maintain.

Organizations that use the notice to audit their lines and plan often avoid years of escalating costs and can migrate on their own schedule, rather than waiting until circumstances force a decision.

If you’re not sure what your copper lines support, a POTS Readiness Assessment can help identify every active line, map it to the systems it serves, and prioritize the best path forward.
