99, commonly called 99App and formerly 99Taxis, is a Brazilian mobility platform owned by DiDi. Its mobile application connects riders with private-car drivers, taxis, motorcycles, delivery or other transportation products available in a particular city. Users enter pickup and destination, select a category, review an estimate, receive driver and vehicle details, travel, pay, rate, and contact support. Coverage, prices, insurance, safety tools, worker relationships, and payment methods vary across Brazil and by current service.
A rider should place pickup and destination pins carefully, especially at airports, stations, gated communities, hospitals, and crowded streets. The application shows the assigned driver, vehicle, license plate, and arrival. All identifying details should match before boarding. Riders should ask the driver whom they are collecting rather than volunteer a name first. A request to cancel and continue privately, use a different car, or pay through an external transfer removes important records and should be refused.
Fares can reflect estimated time and distance, vehicle type, demand, tolls, airport charges, waiting, stops, taxes, and promotions. An estimate can change if the route or destination changes under local terms. Riders should review the authenticated receipt and report duplicate charges or unexpected routes through the trip record. A driver does not need a rider’s password, card number, or authentication code. Cash, where supported, should be selected in the official booking and confirmed against the displayed amount.
Safety features can include GPS records, trip sharing, emergency assistance, masked contact, audio tools, driver checks, ratings, and incident reports. These reduce risk but cannot prevent every collision, assault, theft, or harassment event. Riders should verify vehicles, wear seat belts, limit impairment, and retain control of their route home. Drivers should refuse unsafe loads, unlawful stops, abuse, or intoxicated conduct. Immediate danger requires Brazilian emergency services rather than waiting for ordinary platform support.
99Moto or motorcycle products, where offered, involve greater injury exposure. Riders should use a properly fitted helmet and any required protective equipment, avoid loose clothing, mount only the booked vehicle, and refuse unsafe driving. Local law, age rules, luggage limits, and insurance apply. Speed, lane splitting, weather, and road surface materially affect risk. A lower fare or traffic advantage does not justify riding without correct equipment or with an impaired driver.
Drivers onboard under identity, license, vehicle, insurance, and background requirements. Platform access is not guaranteed work or income. Gross receipts must be reduced by fuel or charging, maintenance, depreciation, insurance, taxes, mobile data, cleaning, tolls, waiting, and return mileage. Personal insurance may exclude commercial use. Drivers should verify coverage, retain independent trip and expense records, and stop when fatigued even if incentives or demand maps encourage continued work.
Ratings, acceptance, completion, safety reports, and other metrics can affect driver access under current rules. Drivers should understand definitions and preserve records for appeals. Account sharing, false location, duplicate identities, bots, and manipulated trips can lead to deactivation and danger. Scammers impersonate driver support, request a code, and redirect payouts. Official support does not need passwords, authentication codes, gift cards, cryptocurrency, remote access, or transfers to protect earnings.
99Pay or other financial features, where available, can use separate entities, fees, limits, and regulatory protections. Riders and drivers should identify the provider before storing funds, borrowing, or transferring. A mobility wallet is not automatically an insured bank deposit. Peer transfers can be difficult to reverse. A caller claiming a refund or safety problem does not need a banking code. Credit offers should be judged by total cost, not convenience inside a familiar app.
The platform processes identity, telephone, precise location, routes, payment, vehicle, rating, audio where enabled, and device data. Location history can reveal home, work, health visits, worship, and relationships. Users should review permissions, secure phones and recovery channels, and remove old payment methods. Fake refund or account messages can use real trip information obtained through compromise. The safest response is to end contact and use verified in-app support.
Travelers should confirm that they have the official Brazilian application, local data, a charged phone, and the destination written independently. They should retain the local emergency number and an alternative transport plan. Businesses using 99 for employee travel should define expense, duty-of-care, incident, and privacy processes. A single consumer app should not be the only plan for critical medical, airport, or safety-sensitive journeys.
99App’s value is convenient on-demand Brazilian transport with digital matching, price estimates, payments, route records, and several local vehicle categories. Its limitations include dynamic prices, variable city coverage, road and personal-safety risk, independent-driver economics, financial-feature complexity, account scams, and extensive location collection. Reliable use requires exact driver and vehicle verification, on-platform booking and payment, seat belts or correct helmets, secure accounts, documented incidents, appropriate insurance, realistic driver cost calculations, and emergency escalation matched to actual danger. Critical journeys need a charged phone, offline destination details, and an alternative transport plan.
