Executive Summary
ParkMobile, one of the largest parking payment platforms in the United States, suffered a data breach in March 2021 after attackers exploited a vulnerability in a third-party software the company used. The misconfiguration allowed unauthorized access to records for approximately 20.9 million customers. Within weeks of the breach, the stolen dataset was posted to a public hacking forum and widely redistributed. The exposed data included names, email addresses, phone numbers, vehicle license plate numbers, and passwords stored as bcrypt hashes. While the password hashing provides some protection, the license plate data is the most consequential element. Combined with parking history, plate numbers can be used to track a person's vehicle movements, identify routines, and infer home or work locations. This creates a risk profile that extends well beyond typical credential breaches. ParkMobile notified affected users, reported the incident to law enforcement, and patched the third-party vulnerability. A class-action lawsuit followed, alleging the company failed to implement adequate security practices. In December 2024, ParkMobile agreed to a $32.8 million settlement. Affected individuals should monitor for phishing attempts using their personal details, consider changing any reused passwords, and be aware that their vehicle and parking history may have been exposed to bad actors.
ObscureIQ assessment: High risk of fraud, account takeover, and physical-world targeting. Parking and vehicle data can reveal routines, commuting patterns, and likely vehicle ownership.
Breach Impact
In March 2021 ParkMobile disclosed a cybersecurity incident linked to a vulnerability in a third-party software it used, resulting in unauthorized access to data for approximately 21 million customers. Exposed data included license plate numbers, email addresses, phone numbers, and bcrypt password hashes. Within weeks the full dataset appeared on a public hacking forum. ParkMobile notified affected users, reported to law enforcement, and eliminated the third-party vulnerability. A class-action lawsuit alleged failure to implement reasonable cybersecurity measures and inadequate encryption practices. In December 2024 ParkMobile agreed to a $32.8 million settlement — one of the larger parking industry breach settlements on record. Class members received $1 in-app credit or up to $25 in cash, reflecting the relatively limited financial harm profile of the exposed data.
About ParkMobile

The company is headquartered in Atlanta and serves municipal parking systems, universities, airports, and commercial parking operators across the United States.

Why They Hold Your Data
Parking-payment platforms collect user identity, phone numbers, vehicle information, payment-adjacent data, location-linked parking records, and reservation history across urban mobility workflows.
Recent Developments
ParkMobile was acquired by EasyPark Group in 2021, the same year as the breach. It has continued expanding its municipal and campus parking partnerships under that ownership. The $32.8 million class-action settlement resolved the primary legal consequence of the 2021 incident.
