The Final Name for Landline Telephony? Not But.


What number of landlines are in service in 2025?

It is true that landline utilization has been lowering in favor of VoIP and different applied sciences—however landline telephony shouldn’t be going away anytime quickly.

This is the information on landline utilization and the speed at which it is being changed across the globe.

The Present State of Landline Utilization

The general public switched phone community (PSTN) reached its peak in 2006 when there was a worldwide complete of 1.22 billion traces in service.

Since then, a median decline of 6% every year has set in. There was no respite in 2024, with the PSTN subscription complete dropping by 16% in 12 months to finish the yr at 407 million.

Of the 225 nations and territories lined by TeleGeography’s GlobalComms Database, solely 17 had larger PSTN penetration charges on the finish of 2024 than they did again in 2005. Of the 208 others, 161 skilled double-digit proportion level reductions over that interval.

Wanting forward, by 2031, the PSTN is forecast to shrink to fewer than 250 million traces in service globally, about one-fifth of its 2006 peak.

VoIP Passes PSTN

Whereas cellular substitution has curtailed alternatives for progress within the mounted voice market, a further cause for the waning of PSTN voice telephony is the comparatively sturdy take-up in voice-over-IP (VoIP) subscriptions.

The entire variety of IP-based voice subscriptions surpassed these related by way of the PSTN for the primary time in 2024, growing 9% year-over-year to roughly 447 million.

TeleGeography forecasts that by end-2031, VoIP traces will outnumber PSTN traces by nearly 300 million. World VoIP family penetration will stand at 21% by that date, whereas solely 10% of households will nonetheless have PSTN phone connections.

France, Japan, Germany, and Portugal have been among the many nations on the vanguard of VoIP take-up. In the beginning of 2025, all 4 had VoIP penetration charges exceeding 75%, and every is anticipated to succeed in a VoIP penetration fee of greater than 90% by the top of 2031.

By that date, VoIP penetration will surpass PSTN penetration in 145 nations and territories.

Total Strains Down 2%

Regardless of the expansion in VoIP, the mixed PSTN and VoIP subscriptions complete declined by 2% in 2024 to 854 million, and is forecast to drop by an annual common of 1.1% per yr between now and 2031.

Mounted voice penetration is declining throughout all areas, besides Africa, the place it is remained steady at round 9%-10% for a number of years. Particular person pockets of progress stay; North African nations, equivalent to Algeria and Egypt, each registered annual progress of 6% in 2024, whereas different notable will increase have been seen in Gabon (up 23%) and Mali (up 15%).

However, family penetration in Africa seems to have already peaked at simply 16% in 2008.

The Transfer to All-IP

It is going to be a long time earlier than the PSTN disappears from all corners of the world, however the pattern towards VoIP is inexorable.

Within the U.S., for instance, in January 2025, AT&T confirmed plans to start the method of discontinuing legacy mounted voice providers in round 25% of its wire facilities. The telco now plans to close all copper-based providers nationwide (apart from California) by the top of 2029.

Though cautious of cannibalizing an current income stream, telcos are rising more and more eager to dismantle the PSTN and embrace all-IP networks.

IP networks are cheaper to keep up, they permit a greater variety of providers equivalent to IPTV, and infrastructure distributors are starting to discontinue help for legacy tools.
