US Soccer Divisions Explained: MLS, USL, NPSL, UPSL & More
If you've ever tried to figure out the US soccer division system, you've probably realized pretty quickly that it's confusing.
Is USL Championship the second division?
Where does MLS NEXT Pro fit?
Is UPSL the fourth division?
What about USL League Two and NPSL?
The short answer is that the United States does not have a traditional soccer pyramid like Germany, England or most of Europe.
There is no promotion and relegation connecting every league. Although, there are plans to change this with the USL system in 2028.
Instead, professional soccer is organized into officially sanctioned divisions, while below the professional game there are several large amateur and semi-professional leagues that don't fit neatly into a true "fourth division" or "fifth division."
Here's how it actually works.
US Soccer League System
U.S. Soccer League System
Unlike most European countries, the United States does not have one connected promotion and relegation pyramid. Here is how the professional, pre-professional, semi-pro and amateur levels fit together.
Winning UPSL, NPSL or USL League Two does not automatically promote a club into USL League One, USL Championship or MLS.
Individual players can move between levels through scouting, trials, outreach, college, agents and club relationships.
Below the professional divisions, the individual club often matters more than an unofficial tier label.
How Does the US Soccer Pyramid Work?
Technically, it isn't really a pyramid.
At least not in the European sense.
In Germany, a fifth-division club can theoretically keep winning promotions and eventually reach the Bundesliga.
A UPSL team cannot simply win enough games to get promoted into USL League One and eventually MLS.
The leagues are separate organizations, and clubs generally enter professional leagues through expansion and league approval rather than promotion based purely on results.
That's one of the biggest differences between American and European soccer.
At the professional level, U.S. Soccer sanctions leagues according to professional league standards.
The main men's professional structure is:
Division I — MLS
Division II — USL Championship
Division III — USL League One and MLS NEXT Pro (NISA is also here, but waiting to be reinstated)
Below those leagues, things become much less formal.
You have USL League Two, NPSL, UPSL and other competitions containing players and clubs with very different levels of ambition and resources.
What Is 1st Division Soccer in the United States?
Major League Soccer (MLS) is the 1st Division men's professional league in the United States.
This is the highest level of the American club game.
MLS includes clubs such as Atlanta United, Inter Miami, LAFC, Seattle Sounders and FC Cincinnati.
For players looking to go professional, MLS is the top domestic destination.
But entering MLS directly is extremely difficult.
Players commonly arrive through routes including:
MLS academies
MLS NEXT Pro
College soccer
Other professional leagues
International transfers
For a player currently competing at the amateur or semi-professional level, it generally makes more sense to think about the steps between your current level and MLS rather than simply emailing MLS clubs.
What Is 2nd Division Soccer in the United States?
USL Championship is the Division II professional level.
It sits directly below MLS in the U.S. Soccer professional division structure.
USL Championship clubs employ professional players and compete nationally.
The league has also become an important destination for players coming from college soccer, MLS academies, MLS NEXT Pro, USL League Two and other domestic and international environments.
If your goal is professional soccer in the United States, USL Championship is absolutely professional soccer.
It isn't "semi-pro" because it's below MLS.
What Is 3rd Division Soccer in the United States?
This is where things start getting more confusing because there isn't just one league.
At the Division III professional level, you'll find USL League One and MLS NEXT Pro.
Both operate at the professional level, but they're very different ecosystems.
What Is USL League One?
USL League One is a Division III professional soccer league.
It includes independent professional clubs competing in markets around the country.
For players trying to break into professional soccer, USL League One can be particularly interesting because clubs have professional first-team rosters while operating below USL Championship and MLS.
Players can arrive from college soccer, USL League Two, MLS development environments, other professional leagues and international clubs.
What Is MLS NEXT Pro?
MLS NEXT Pro is also a Division III professional league.
But it serves a different purpose from USL League One.
Many MLS NEXT Pro teams are directly affiliated with MLS organizations and play an important role in developing players between academy soccer and MLS first teams.
That makes MLS NEXT Pro particularly relevant for younger players already inside or close to the MLS development system.
You'll see academy players, young professionals, MLS players getting minutes and outside signings competing in the same league.
So while MLS NEXT Pro and USL League One can both sit at Division III, that doesn't mean the pathway into each league is identical.
Is USL League Two the 4th Division?
You'll often see USL League Two described as the fourth tier of American soccer.
That's useful as shorthand, but it isn't technically the same thing as saying USL League Two is an official U.S. Soccer Division IV professional league.
There currently isn't an official Division IV professional designation underneath Division III in the same way there is Division I, II and III.
USL League Two describes itself as a pre-professional league.
It's particularly important for college players because they can compete during the summer while maintaining college eligibility when applicable.
And it's a legitimate pathway.
Players regularly use USL League Two to get competitive games, build film and put themselves in environments where professional clubs can evaluate them.
Is NPSL the 4th Division?
The National Premier Soccer League (NPSL) is another league commonly placed around the unofficial fourth tier of American soccer.
Again, "fourth tier" is useful for visualizing where it sits in the broader ecosystem.
But NPSL is not an officially sanctioned Division IV professional league.
The league includes clubs from across the country, and the level and structure can vary considerably between teams.
Some clubs are highly ambitious and operate in strong soccer markets.
Others are much smaller.
That's why evaluating the individual club matters just as much as looking at the league name.
What Division Is UPSL?
The United Premier Soccer League (UPSL) is one of the largest adult soccer competitions in the United States.
It's also one of the most misunderstood.
UPSL is frequently called:
"Fourth division"
or:
"Tier 4."
That's not an official professional division designation.
It's better to think of UPSL as part of the large amateur/semi-professional layer sitting underneath America's sanctioned professional leagues.
And UPSL itself contains different levels of teams.
You can find former professional players, college players, academy players, international players and adult amateur players competing within the broader UPSL ecosystem.
The quality can vary significantly from club to club and market to market.
Is UPSL Professional or Semi-Pro?
This is another area where terminology gets messy.
You'll frequently hear UPSL clubs described as semi-professional.
That doesn't mean UPSL itself is a U.S. Soccer-sanctioned professional league.
Individual clubs can operate very differently.
Some organizations are ambitious and structured almost like lower-level professional clubs.
Others are essentially high-level adult amateur teams.
So if somebody tells you:
"I play fourth division professional soccer in America because I play UPSL."
That's not really an accurate description.
A better description would usually be:
"I play UPSL, which is an amateur/semi-professional level below the sanctioned professional divisions."
USL League Two vs NPSL vs UPSL
Players constantly compare these three.
The problem is that there isn't a universal answer saying:
USL2 > NPSL > UPSL
for every team in America.
The quality varies.
A strong USL League Two team with NCAA Division I players and professional academy prospects can be extremely good.
A strong NPSL team can be extremely good.
A strong UPSL club can also have players capable of moving higher.
Instead of evaluating only the league, look at:
The club
The roster
The coaching staff
Where their players came from
Where their players move next
The quality of competition
Whether professional scouts actually have a reason to watch them
That's much more useful than arguing about whether one league should be called "Tier 4" or "Tier 5."
Can You Go Pro From UPSL?
Yes.
But playing UPSL doesn't automatically put you on a conveyor belt to professional soccer.
There is no automatic:
UPSL → USL League One → USL Championship → MLS
promotion pathway.
The player has to move.
That might happen through:
Professional trials
Showcases
Direct outreach
Coach recommendations
Agents
Scouts
Open tryouts
Personal connections
Strong performances and film
This is an important distinction in American soccer.
Your club doesn't necessarily have to move up for you to move up.
Can You Go Pro From USL League Two?
Yes.
USL League Two has historically been an important environment for players trying to move into professional soccer, particularly college players.
Professional clubs can scout the league, and players can use the season to build competitive film and prove themselves against other strong players.
But again, simply being on a USL League Two roster doesn't guarantee professional exposure.
You still need to perform.
And in many cases, you still need to actively put yourself in front of the right people.
What Level Should You Play At?
Don't obsess over finding the league with the highest-sounding name.
Find the highest level where you're actually going to play.
Sitting on the bench for a strong team isn't automatically better for your career than starting every week for a slightly lower-level club.
You need:
Minutes
Film
Development
Good coaching
Strong competition
Connections to the next level
And ideally, you want evidence that players from that club have actually moved somewhere you want to go.
That's one of the first things I'd research before joining any lower-division team.
How Do You Move From Semi-Pro to Professional Soccer?
This is where the American system is very different from Europe.
Your team isn't going to get promoted into USL League One just because you win UPSL.
So if you're ready for a higher level, you have to create opportunities to be evaluated.
That can mean getting introduced to professional staff, attending legitimate trials, working with an agent, performing at events where professional teams are watching or contacting clubs directly.
And if you're contacting clubs yourself, don't just send your highlights to:
Figure out who actually handles players.
That could be the:
Sporting Director
Technical Director
Head Coach
Recruitment staff
General Manager
Then approach that person professionally.
