How to Call a Landline in 2026: From Cell Phone, Internationally & More
Learn how to call a landline from a cell phone, internationally, and via VoIP. Covers 10-digit dialing rules, trunk prefix, landline vs mobile differences, and the AT&T copper shutdown timeline.

To call a landline from a cell phone, just dial the full 10-digit number — area code + local number. No special prefix needed. For international landlines, dial + country code + area code (drop the 0) + number. That's it.
This guide covers how to call landlines domestically and internationally, the difference between landline and mobile calls, why landline rates are cheaper for international calls, the current state of landlines in 2026 (hint: 78% of Americans are wireless-only), and the AT&T copper network shutdown that's changing everything.
Quick Guide: Calling a Landline
From a Cell Phone (US domestic)
Area code + 7-digit number
Example: 212-555-1234
From Another Landline (US domestic)
1 + Area code + 7-digit number
Example: 1-212-555-1234 (the "1" is the long-distance prefix)
From US to International Landline
+ Country code + Area code (no 0) + Number
Example: +44 20 7946 0958 (UK) or from landline: 011-44-20-7946-0958
10-Digit Dialing Is Now Mandatory
Since October 24, 2021, 10-digit dialing (area code + number) is mandatory in most US area codes. This change was required for the launch of 988 — the Suicide & Crisis Lifeline — which needed to ensure calls to 988 wouldn't conflict with 7-digit numbers starting with 988.
What this means: Even if you're calling a landline across the street, you must dial the full area code + number. The few areas that still allowed 7-digit dialing (parts of Massachusetts, Nebraska, Oklahoma, South Carolina, Utah) are being phased to 10-digit as well.
How to Call International Landlines
International landline calls follow a simple formula: exit code + country code + area code + local number. The key is dropping the trunk prefix — the leading 0 that locals use for domestic calls.
| Calling To | Local Format | From US Mobile | From US Landline |
|---|---|---|---|
| UK (London) | 020 7946 0958 | +44 20 7946 0958 | 011-44-20-7946-0958 |
| India (Delhi) | 011 2345 6789 | +91 11 2345 6789 | 011-91-11-2345-6789 |
| Germany (Berlin) | 030 1234567 | +49 30 1234567 | 011-49-30-1234567 |
| Japan (Tokyo) | 03 1234 5678 | +81 3 1234 5678 | 011-81-3-1234-5678 |
| Australia (Sydney) | 02 1234 5678 | +61 2 1234 5678 | 011-61-2-1234-5678 |
Trunk prefix reminder: Always drop the 0 before the area code. UK 020 → +44 20. India 011 → +91 11. Germany 030 → +49 30.
Landline vs. Mobile: Key Differences
| Feature | Landline | Mobile |
|---|---|---|
| Location | Fixed to one address | Portable anywhere |
| Area Code | Geographic (tied to region) | Can keep any area code |
| Power Outage | Corded phones work (copper only) | Needs battery + cell towers |
| Simultaneous Calls | One at a time (busy signal) | Call waiting standard |
| International Rates | Often cheaper | Higher (mobile termination fees) |
| Sound Quality | Consistent, reliable | Varies by signal strength |
The State of Landlines in 2026
78%
of US adults are wireless-only
~55M
Americans still have a landline
90%→20%
landline usage: 2004 → 2026
The Northeast has the highest landline rate (33% of adults), while states like Idaho, Utah, and Oklahoma have cut cords fastest. The 65+ age group is most likely to keep a landline (40.7%). In the last year alone, 6.5 million US households dropped their landlines.
Why People Still Keep Landlines
The AT&T Copper Network Shutdown
AT&T spends ~$6 billion annually maintaining its legacy copper network, but less than 3% of customers still use it. The FCC streamlined copper retirement rules in March 2025, and the shutdown is now underway:
Customers will be migrated to fiber-optic or VoIP alternatives. This means the unique advantage of copper landlines — working during power outages — will disappear for most users.
