The UK and Republic of Ireland submitted an expression of interest in staging the European Championships in the year 2028.
A feasibility study was conducted on a potential World Cup bid by the five associations.
They decided to focus on Euro 2028 in February.
It would be one of the greatest sporting events held in the UK and Ireland according to the associations.
In a joint statement, the FAs of England, Northern Ireland, the Republic of Ireland, Scotland and Wales said that submitting an expression of interest to Uefa was an important step.
The governments of the UK, Ireland, Scotland and Wales have confirmed their support for the expression of interest submission and, given the Northern Ireland Executive is currently not meeting formally, officials there continue to observe the process closely.
This unprecedented partnership of five associations offers something special to European football, including the potential for an expanded tournament, and we are passionate about maximizing the benefits for communities across the UK and Ireland.
The joint bid team expects to engage in conversations with potential host cities and stadiums once they receive the Uefa technical specification for bidding for the tournament.
The chair of the Digital, Culture, Media and Sport (DCMS) committee encouraged the focus to be on bidding for Euro 2028 rather than the World Cup.
