Lost something at Miami International Airport (MIA)? Where you report it depends on where you lost it. Items left in the terminal or a public area go to the Miami-Dade Aviation Department Lost & Found; anything left at a security checkpoint is held by the TSA; and something left on the aircraft or at the gate is handled by your airline. Acting fast and knowing the right office to call makes a real difference.
At a glance: who to contact for what
| Where you lost it | Who has it | How to reach them |
|---|---|---|
| In a terminal, concourse or public area | Miami-Dade Aviation Dept — MIA Lost & Found | North Terminal D, Level 4 — open daily 8:00–18:00. Report via the official online Lost Item Claim form (general info 305-876-7000) |
| At a TSA security checkpoint | TSA Lost & Found at MIA | TSA at MIA (details on mia.gov / tsa.gov) |
| On the aircraft or at the gate | Your airline's baggage service office | The airline's lost-item form or baggage desk |
| In a taxi or rideshare | The taxi operator or Uber/Lyft | In-app "lost item" report or the operator's line |
| In a rental car or hotel shuttle | The rental agency or shuttle operator | The company's desk at MIA |
| In a parking garage or on the MIA Mover | Miami-Dade Aviation Dept Lost & Found | Same as the terminal office above |
Step one: work out who has your item
The most common mistake is calling the wrong office and waiting on a queue that was never going to have your bag. Retrace the last place you had the item. If it was past security inside the terminal — a food court, a restroom, a seating area, a shop — it falls under the airport's own lost and found. If you set it down at the screening checkpoint, the TSA holds it separately. If you realise only after landing that it is still on the plane, that is the airline's responsibility, not the airport's.
Items lost in the terminal (Miami-Dade Aviation Lost & Found)
Miami International Airport is run by the Miami-Dade Aviation Department, and it operates a central Lost & Found for items handed in from the terminals, concourses, parking garages and the MIA Mover. Report your item as soon as you can and be ready to describe it in detail: brand, colour, distinguishing marks, and roughly where and when you lost it. The more specific you are, the faster staff can match it. The office is on Level 4 of North Terminal D and is open daily from 8:00 to 18:00, year-round. The quickest way to start a claim is the airport's official online Lost Item Claim form; if you have already left the airport you can file remotely rather than travelling back. For general enquiries the airport information line is 305-876-7000 (or 1-800-825-5642).
Items left at a TSA checkpoint
Anything you leave behind at the security screening area — a laptop, a phone, a belt, a jacket — is collected by the Transportation Security Administration (TSA), not the airport, and held in a separate TSA lost and found at MIA. Electronics and IDs are logged carefully, so report a missing item quickly and mention it was left at the checkpoint so you are routed to the right team.
Items left on the plane or at the gate
If your item is still on the aircraft or was left at the gate, contact your airline directly rather than the airport. Most carriers have an online lost-item form and a baggage service office near the arrivals level. Have your flight number, seat and travel date ready. For items that were checked or went missing from luggage, that is a baggage claim matter handled by the airline as well.
Taxis, rideshare, rental cars and shuttles
Left something in the car? For Uber or Lyft, use the app's "I lost an item" flow, which connects you to your driver. For a taxi, contact the taxi operator with the trip details. For a rental car or a hotel shuttle, call the company's desk at MIA. These are private operators, so the airport's lost and found will not have these items.
How long is a lost item kept?
Unclaimed items at MIA are held for 30 days, after which they are donated, disposed of or sent to state unclaimed-property processes — so speed matters. Start your claim as soon as you realise something is missing.
Tips to recover a lost item faster
- Report the same day if you can. Fresh reports are easier to match against items just handed in.
- Be specific. Serial numbers, phone lock screens, bag tags and unique marks help staff confirm the item is yours.
- Use "find my" apps. If a phone, tablet or tracker is involved, a live location tells you whether it is airside, in a vehicle or already off-site.
- Keep your reference. Note any case or report number so follow-up calls are quick.
