It’s a move that may signal more frequent returns to the 74,500-capacity arena in the coming years.
The home of Welsh rugby has only rarely been used by the national football side over the past decade.
In fact, since 2011, Wales have played there just once — a 4-1 friendly loss to Spain in October 2018.
Instead, Cardiff City Stadium has become the team’s established base, its 33,280 seats providing the backdrop for memorable qualification campaigns for Euro 2016, Euro 2020 and the 2022 World Cup.
However, with Cardiff set to host six matches at Euro 2028 — including the tournament’s opening fixture and all three of Wales’ group games should they qualify — the Football Association of Wales is keen for Craig Bellamy’s squad to become reacquainted with the larger venue.
An England clash in the Nations League would offer the perfect occasion.
While the switch would be a departure from recent practice, it is one that FAW chief executive Noel Mooney has openly discussed as part of longer-term planning ahead of the European Championship on home soil.
"We've got to sharpen our mind as we're hosting the Euros in the Principality Stadium and think about the right time to play there," Mooney said.

"There's no two ways about it. We're not going to turn up like tourists for the opening match of Euro 2028.
"When we do play there hasn't been decided yet. But logic would tell you that if you've got a very big country, for example England in the Nations League, we'll go there."
Such a decision would be notable given how infrequently the stadium has featured in Wales’ modern football story.
Cardiff City Stadium has provided familiarity and atmosphere in equal measure, becoming something of a stronghold during recent qualification successes.
Yet the scale and spectacle of the Principality Stadium — particularly with a major tournament looming — present a compelling case for change.
The next Nations League fixtures are scheduled across two international windows: September 24 to October 6, 2026, and November 12 to 17.
A November date at the Principality Stadium would appear improbable due to likely clashes with Wales’ autumn rugby internationals, meaning an early-autumn showdown would be the more realistic scenario if England and Wales are drawn together.

Wales enter the Brussels draw as one of League A’s fourth seeds.
England and Belgium sit in Pot 3, while Italy and the Netherlands headline Pot 2. France, Germany, Spain and Portugal are the top-ranked sides in Pot 1.
For Mooney, the Nations League offers a competitive environment distinct from traditional qualifying campaigns, adding further weight to venue considerations.
"There's a different jeopardy to Nations League than there is to qualifiers, because you don't lose your competitive edge around qualifiers," he said.
The FAW intends to consult widely before confirming any shift in venue, mindful of supporters, team staff and commercial stakeholders.
But there is also recognition that decisions cannot be delayed indefinitely if players are to build familiarity with the stadium before Euro 2028 arrives.
"We'll talk to the relevant stakeholders, the management team and the supporters," Mooney added.
"I think that consultation should happen sooner rather than later, so people have a clear vision of what games we're going to play at the Principality Stadium before we go to Euro 2028 because you can't leave it too late either.
"You want the players to be used to the stadium before they go there."
An England tie would not only be a high-profile test but also a symbolic return to the national stadium — potentially the first step towards re-establishing the Principality as a more regular football venue in the build-up to 2028.
