Short version: the NCAA picks the 68 teams, assigns those teams to four regions, can reseed after early results, and separately awards hosting rights to cities through a bid process years in advance. Nothing about how March Madness regional sites are chosen happens on Selection Sunday. That is the part almost every fan gets wrong.
I watched this confuse a table of fans last March. One person was convinced a school had been snubbed because its city was hosting. Another assumed a regional was a ranking tier. Both were working from the same mental model, and it was wrong. Four different decisions get tangled together, and untangling them is the whole answer.

How March Madness Regional Sites Are Chosen
Understanding how March Madness regional sites are chosen means separating four decisions that run on four different clocks.
- The field. Which 68 teams get in, decided by the NCAA Division I Men’s Basketball Committee in mid-March.
- The regions. Which of the four named regions (East, West, South, Midwest) each team lands in, decided at the same meeting.
- Reseeding. Whether early results force teams to move, decided by the committee during the first two rounds.
- The venues. Which cities and arenas host each round, decided years earlier by a separate NCAA awards process.
The committee handles the first three. It has no say in the fourth. Cities don’t bid to host a specific team or a specific region; they bid to host a round of the tournament for a specific year.
That split is why bracketology can change your team’s city every week for months. Projections place teams in regions, regions imply sites, and sites are fixed years in advance. So the cities swing around while the arenas stay put.
What Determines the 68-Team Tournament Field?
The field comes from 31 automatic qualifiers and 37 at-large selections. Automatic bids go to conference tournament champions, which covers roughly 31 spots. At-large bids fill the remainder and are the committee’s call.
The committee works from criteria it publishes in advance, and those criteria lean on a ranking system the NCAA built to be as transparent as a ranking can be. The core pieces include:
- Win-loss record, with a cap on how much a single blowout win can move a team
- Strength of schedule, measured against other Division I competition
- Wins against opponents that themselves rank well, which is why beating a good team matters more than beating a bad one
- Conference tournament performance, with play-in games filling the final open spots
- Continuity of success, including whether a team is returning to the same tournament
Ranking releases run weekly through the regular season, then monthly into February. The February ranking is the one the committee treats as its primary reference when it builds the field.
None of that has anything to do with arenas. The committee selects teams. It does not award regional sites to individual schools, and a school cannot lobby for a better regional site because of the building it owns.
Why field selection and regional site selection are different processes
Because they answer different questions. Field selection asks who has earned a place. Site selection asks who can host games well and cheaply enough to run a national championship round. Mixing them produces the wrong conclusion every time: a team is not passed over for a site, and a city is not denied for a team.
How Are Teams Placed Into the Four Regions?
Placement starts with the seed. The committee ranks all 68 teams from 1 to 68, then distributes those seeds across four regions so that each region has sixteen teams: four 1-seeds, four 2-seeds, and so on down through the 16-seeds.
Raw seed balance is the starting point, not the finish. The committee then weighs factors that a spreadsheet cannot weigh.
Seed-line balance
The committee aims for each region to be competitive at every stage. If one region held five of the top ten teams and another held none, the bracket would be lopsided before a tipoff. The seed distribution exists to prevent that, and the committee can move a team within its seed line to tighten things up.
Conference placement rules
Conference membership heavily influences which teams land where. The general principle is that teams from the same conference should not meet before the Sweet Sixteen when the committee can avoid it, since most fans travel to follow their own league. Exceptions get made when a conference is unusually deep or unusually weak.
The pod system and travel distance
This is the part that confuses people most. First and second round games are not played at all eight regional sites. Each regional site sits inside a pod of first and second round venues grouped by geography, so a team plays its opening games nearby and then travels to the regional site.
The result is a 1-seed playing its first two games roughly 100 miles from campus while a 9-seed crosses the country, because the seeding dictates who has to play whom. Forum discussion on r/CollegeBasketball keeps circling this same complaint every year, and it is a fair one. The pod system minimizes travel for high seeds by design, and the burden lands on the teams the committee expects to lose early.
Geography and proximity
After conference and seed constraints, distance breaks the remaining ties. Reference points fans use when debating a projection are 300 miles, 500 miles and 1,000 miles. A placement inside 300 miles rarely draws complaints. One beyond 1,000 miles draws plenty.
Worked example: two teams ranked 9 and 10 by record. The 9-seed has played most of its schedule against strong opposition, so the committee treats it as the better team and seeds it above the 10-seed. The 10-seed draws from a conference that already has two teams in the East region, so it goes to the South. Same conference strength, different destination, and the difference came down to conference placement rules rather than geography.
A handful of special constraints also exist. BYU does not play on the Sabbath, so no game can be scheduled for that team on Sunday, which reshuffles session times wherever it lands. These are exceptions the committee grants explicitly rather than rules it works around silently.
Does the NCAA Re-seed Teams After Selection Sunday?
Yes, and this is where fans watching a bracket over two days sometimes get confused. The committee reviews results during the first two rounds and can reseed teams as the field changes.
The First Four is the clearest example. Those games are played first, on the Thursday and Friday before the main bracket. When they finish, four winners have to join a field that was already built around teams who lost early-round games. The winners are seeded into those vacated slots.
Reseeding can also move teams between regions, not just up and down seed lines. If a team wins in a way that makes its current placement lopsided, the committee may move it so the later rounds stay competitive.
What reseeding does not do is change the venue. A team that moves from the West regional to the East regional still plays its regional games at the West regional’s arena, with the other teams assigned to that site. The site stays attached to the region, not to the individual team.
What reseeding changes and what it doesn’t
| Event | What reseeds | What stays fixed |
|---|---|---|
| First Four concludes | Four play-in winners seeded into vacated first-round slots | All 16 first and second round venues |
| First round completes | Teams can be moved between seed lines or regions | The four regional arenas and their dates |
| Second round completes | Sweet Sixteen matchups reflect new placement | Regional sites hosting the Sweet Sixteen and Elite Eight |
| Regional semifinals | Nothing, no reseeding remains | Final Four city and arena |
How Are the Regional Hosts and Venues Chosen?
This is a completely separate process, run by NCAA staff with the championships oversight structure, and it starts long before anybody knows which teams are playing. Cities and institutions submit bids through the NCAA’s host bid system. The bids get evaluated, shortlisted, and awarded by committee rather than by any single person.
The NCAA moved from a four-year bid cycle to a two-year cycle, which shortened the runway considerably. Under the shorter cycle, a host can be re-awarded sooner, but it also means a venue that stumbles on hosting gets fewer chances to recover before rotating out.
The eight first and second round sites are assigned to a set of four regional sites ahead of the tournament too. Those pairings are planned years in advance, which is why a first round site can be a short drive from the regional arena rather than across the country.
What the NCAA scores in a city bid
Bids get scored against published specifications. The recurring criteria across rounds are:
- Venue capacity, measured in saleable seats rather than raw seats, with minimums that rise by round
- Neutral-site status, so neither team in a game can claim home-court advantage
- Geographic diversity, spreading sites across regions rather than stacking them in familiar corners
- Fan access and amenities, concourses, concessions, seating sightlines, and general comfort across multiple sessions in one day
- Transportation, proximity to a major commercial airport and workable ground travel between venues and hotels
- Hotel inventory, enough rooms in a tight radius to house teams, staff and traveling fans on short notice
- Financial terms, what the host institution and local partners contribute toward event costs
- Operational readiness, staffing, security planning, accessibility compliance and broadcast infrastructure
Security planning has drawn more scrutiny in recent years, and venues that have hosted repeatedly tend to have existing scaling plans rather than building them from scratch.
Capacity minimums by round
| Round | Minimum saleable seats | Typical pattern |
|---|---|---|
| First Four | 10,000 | One city hosts all four play-in games |
| First and Second Round | 10,000 | Eight sites across four regional pods |
| Sweet Sixteen and Elite Eight | 15,000 | Four regional sites |
| Final Four | 70,000 | One city hosts three rounds plus a championship game |
The Final Four minimum is high enough that it narrows the field sharply. Cities that clear 70,000 saleable seats, run a championship in a neutral venue and can handle championship-week security are a short list.
Local organizing committees handle the on-site work once a site is awarded. They manage ticket allocation, volunteer staffing and city-wide fan programming, and they report through an NCAA championship manager rather than dealing with the selection committee.
What Is the Difference Between a Regional Site, Region, and Bracket?
These four terms get used interchangeably when they mean four different things. Here is the clean version.
| Term | What it is | Who decides it | When you learn about it |
|---|---|---|---|
| Region | A named 16-team section of the field, such as the East or the South | Selection committee on Selection Sunday | Selection Sunday |
| Regional site | The city and arena hosting the Sweet Sixteen and Elite Eight for one region | NCAA host awards process | Years in advance |
| Regional semifinal | The two Sweet Sixteen games played at a regional site | Follows from seeding and results | Selection Sunday, updated daily |
| Regional final | The Elite Eight game at a regional site that sends one team to the Final Four | Follows from regional results | Selection Sunday, updated daily |
Regional names have also shifted conventions over the years, which adds to the confusion. Regions get renamed and reassigned while the venues stay put. Treat the region name as a label on a group of teams, never as a ranking category or a place.
When Are the March Madness Regional Sites Announced?
Host sites are announced years ahead of the tournament they serve. Regional sites for a given tournament are locked well before Selection Sunday, often at the same time the first and second round pairings for that region are established.
The calendar fans actually follow runs like this:
- Bid awards, years ahead. Regional sites and Final Four cities are named for future tournaments, well before any team is known.
- Weekly ranking releases during the regular season. The committee’s ranking updates and reshapes field projections.
- February ranking. The most-cited ranking before Selection Sunday.
- Selection Sunday. The field of 68, the seeds, and the four region assignments are announced together.
- First Four, then the first two rounds. Results come in, reseeding happens, and the Sweet Sixteen picture firms up.
- Regional weekends. Venues are fixed and announced; only the teams playing there are still settling.
The practical takeaway: if you want to plan travel, the city list is reliable now and the team matchups are not. If you want to predict matchups, bracketology is your tool, and you should expect the cities attached to those projections to stay accurate because the arenas were chosen years ago.
Sources worth trusting on the process, in rough order: the NCAA’s own bid specification documents, the selection committee’s published criteria, and data-driven projections from sources like TourneyCast and the Bracket Matrix rather than pundit bracket picks.
Frequently Asked Questions
Are March Madness regional sites chosen by the teams that play there?
No. Cities and institutions submit bids to host a round of the tournament for a given year, and the NCAA awards those bids through a separate process driven by venue capacity, neutrality, geography, amenities and finances. Teams never select the arena they play in. Once a team is picked, the site is already fixed and the team is simply assigned to it.
When does the NCAA announce the four regional host cities?
Years in advance of the tournament itself. Regional sites hosting the Sweet Sixteen and Elite Eight are awarded before any team is known, and the eight first and second round venues are paired to those regionals ahead of time as well. The NCAA moved to a shorter bid cycle, so awards and re-awards now happen on a more frequent rotation than earlier bid rules required.
Can a team change regions after Selection Sunday?
Yes, the committee can reseed, and that can include moving a team between regions. Reseeding most often happens after the First Four, when four winners need slots in a field already built around early losers. The committee also reviews results during the first two rounds and can adjust placement to keep later rounds competitive.
Does reseeding change the regional site where a team plays?
No. The arena stays attached to the region, not to an individual team. A team that moves between regions during reseeding plays its Sweet Sixteen and Elite Eight at the arena assigned to its new region, alongside whichever other teams land there. Venues and dates are fixed well before Selection Sunday and reseeding never relocates games.
How do NCAA tournament committees balance seeding and travel?
Seeding comes first, and travel is applied within the constraints it creates. The committee distributes seeds across regions for balance, respects conference placement rules where possible, then uses geography to break remaining ties. The pod system follows from this, grouping first-round venues near each regional arena so high seeds travel less and low seeds travel further.
Where can fans find the official bracket and regional assignments?
The NCAA publishes the official bracket, the complete seed list and the full set of first and second round site pairings after Selection Sunday, with results updating as games are played. Host city and venue lists for future tournaments are posted separately and much earlier. Checking both is the fastest way to see a real path rather than a projected one.
Conclusion
The cleanest way to hold all of this: team selection and venue selection never touch. The committee picks 68 teams in March, seeds them into four regions, and may reseed after early games. Cities won hosting rights years before any of that, based on arenas and infrastructure rather than basketball.
If you are planning to follow a team, start with the published bracket and seed list, then confirm the host city and arena for the round you care about. Ignore any bracketology projection that implies a site could still be in play. Those venues were settled a long time ago.
