Tracking packages with stationary bar code reader in a warehouse sorting operation

Package tracking or package logging is the process of localizing shipping containers, mail and parcel post at different points of time during sorting, warehousing, and package delivery to verify their provenance and to predict and aid delivery.

Package tracking developed historically because it provided customers information about the route of a package and the anticipated date and time of delivery.[1] This was important because mail delivery often included multiple carriers in varying environmental circumstances, which made it possible for a mail to get lost.[2][3]

Identification

[edit]

Mail tracking is made possible through certified mail and registered mail, additional postal services that require the identity of a piece of mail to be recorded during various points of delivery, so that the sender can obtain a proof of delivery and the receiver can predict the time of delivery.[2] The service is provided for an additional charge[4][5] but recently free service has been introduced as the cost of the associated technology has been decreasing.[6]

Initially, a piece of mail was identified by the sending date and the addresses of the sender and the recipient; later tracking numbers came to be used for identification.[7] Traceability has been improved even further by barcoding: by non-specific 1D linear barcodes and 2D matrix barcodes and specialized augmented postal codes such as Postal Alpha Numeric Encoding Technique (PLANET), Postal Numeric Encoding Technique (POSTNET) and Intelligent Mail barcode, and other electronic product codes (EPC-s).

Methods

[edit]

To identify the location of the mail, two methods have been used. One approach involves reporting the arrival or departure of the package and recording the identity of the package, the location, the time, and the status. This approach has been used for package tracking provided by the delivery companies, such as Deutsche Post, United Parcel Service, AirRoad, or FedEx. Another approach is to use a GPS-based vehicle tracking system and nowadays Beacons to locate the vehicle that contains the package and record it in a real-time database.[8]

As package tracking technologies have evolved, it has also become possible to increase the amount of information and metrics returned about a package and to report beside its location also temperature, humidity, pressure, acceleration, elevation and exposure to light at different time points—factors that are important for delicate or perishable contents.[1]

Querying and reporting

[edit]

Web-based package tracking has been used from the early days of the Internet[9] to automate customer service and as a cheaper alternative to phone-based call centers, providing the ability to track the status of a package "within minutes".[9] The service became quickly popular: for UPS the number of packages tracked on the web increased from 600 a day in 1995[9] to 3.3 million a day in 1999.[10] On-line package tracking became available for all major carrier companies, and was improved by the emergence of websites that offered consolidated tracking for different mail carriers.[11] With the rise of smart phones, package tracking mobile apps were able to send tracking info to customers' cell phones. With improved data processing, e-mail programs were able to automatically detect tracking numbers in messages[12] and receipts and print the real time location of the package.[13]

Internal package tracking

[edit]

Most traditional package tracking systems do not track packages after a package is dropped off at a centralized mail services center with single-point delivery, such as the ones used at apartment complexes, college residence halls, corporate mailrooms, post-office box stores and mail and parcel centers. These mail services centers receive all incoming mail and sort it; the mail may then be delivered to individual recipients or the recipients may have to pick up the mail themselves. To cover that gap and track a package at different points within the internal delivery process, specialized internal or "inbound" package tracking systems have been developed.

These systems log in the packages that arrive by recording the items from different carrier companies, the time the delivery is made, the name of the recipient, tracking number and other data. The recipients are notified of the packages or sent reminders. Once the package is received by the end recipient, the systems record the timestamp, the recipient signature and method of authentication and the package is logged out.

Several technologies have evolved with slightly different features (Winn Solutions or WITS, PackageLog, PakLog, SCLogic, TekTrack, Oden Industries, Inc. (PacTrac), WTS by Quadient and others), including patented solutions.[14]

For carriers, it delivers key benefits including substantial cost savings through reduced instances of lost parcels—potentially lowering losses by up to 30%—and minimized operational inefficiencies. Additionally, by facilitating route optimization, tracking contributes to environmental , decreasing fuel consumption and carbon emissions associated with inefficient deliveries.

Historical Development

Package tracking originated in the 19th-century postal services, where manual logging and record-keeping were employed to monitor mail and parcels across expanding networks. In the United States, the , operational from April 1860 to October 1861, represented an early milestone in expedited delivery, using a relay system of horse-mounted riders to transport mail over 1,900 miles from to in about 10 days, with rudimentary documentation such as waybills to record shipments at relay stations. This service, though short-lived due to the completion of the transcontinental telegraph, highlighted the need for faster and more reliable tracking methods in remote areas. Advancements in the shifted toward mechanized and computerized systems. In 1979, Federal Express (now ) introduced the (Customer, Operations, and Service Master Operating System), a centralized computer system that enabled real-time tracking of packages, vehicles, and weather conditions, revolutionizing logistics by providing updates accessible to customers. During the 1980s, major carriers like (UPS) adopted technology for package identification and sorting, allowing drivers to scan labels with handheld devices to update shipment status electronically, marking a transition from manual to automated processes. The digital era began in the mid-1990s with the launch of web-based tracking platforms. UPS debuted its website in 1994, followed by online tracking capabilities in 1996, initially handling modest volumes that scaled dramatically as adoption grew, reaching tens of millions of queries daily by the early . By the 2010s, mobile applications further enhanced accessibility; for instance, UPS released its app in 2009, enabling users to track shipments, locate stores, and manage deliveries on the go.

A notable development in this was Tive's $54 million Series B in 2022, which accelerated advancements in sensor-based visibility solutions for supply chains.

Identification Systems

Tracking Identifiers

Tracking identifiers are unique alphanumeric codes assigned to individual packages to enable their monitoring throughout the shipping process. These identifiers, often referred to as tracking numbers, serve as the primary means of distinguishing one package from another in vast logistics networks operated by carriers worldwide. The most common types of tracking identifiers consist of 10 to 34 digits or characters, varying by carrier and international standards. For instance, the United States Postal Service (USPS) typically uses a 22-digit numeric format for services like Priority Mail (e.g., starting with 9400), with variations for other mail types. Internationally, the S10 format for freight containers is specified by ISO 6346, a 10-character code using uppercase letters A-Z (excluding I, O) and digits 0-9, consisting of a 3-letter owner code, 6-character serial number, and 1 check digit. For parcels, standards like the GS1 Serial Shipping Container Code (SSCC), an 18-digit numeric identifier, enable unique tracking in supply chains. The structure of these identifiers is meticulously designed to encode essential information while incorporating error-detection mechanisms. Key components often include a carrier-specific prefix (e.g., indicating the shipping service or origin), a serial number for uniqueness, and a checksum digit calculated via algorithms such as the modulo-10 method, which validates the code's integrity by verifying that the weighted sum of digits modulo 10 equals zero. This structure allows carriers to embed details like service type and point of origin without compromising the code's brevity or scannability. Tracking identifiers are generated automatically during the shipment creation process, typically by the carrier's or shipping software, ensuring each package receives a globally unique code to avoid duplicates across interconnected networks. This begins at the point of printing or manifest entry, integrating with the carrier's database to link the identifier to package details like weight, dimensions, and destination. Prominent examples illustrate these conventions: UPS tracking numbers often start with the "1Z" prefix to denote ground or air services, followed by the shipper's six-digit account number, a three-digit service code, and an eight-digit package identifier, culminating in a —resulting in an 18-character string. Similarly, uses a 10- or 11-digit numeric code that incorporates shipper account information and a , facilitating seamless tracking across its international operations. These identifiers are ultimately scanned at key points in the to update status information, as detailed in subsequent tracking methods.

Labeling Technologies

Labeling technologies for package tracking encompass a range of physical and digital methods designed to affix machine-readable identifiers to parcels, enabling efficient identification and data capture throughout the . These technologies include traditional systems, (RFID) tags, and emerging (NFC) and smart labels, each offering varying levels of data capacity, readability, and environmental resilience. Barcode systems remain a foundational labeling approach, with one-dimensional (1D) barcodes such as and (UPC) used for encoding basic identification information like product or shipment numbers. , standardized under ISO/IEC 16388, supports alphanumeric characters and is widely applied in for its simplicity and compatibility with linear scanners. In contrast, two-dimensional (2D) barcodes, including QR codes and , provide higher data density, accommodating additional details such as timestamps or serial numbers in a compact format. These 2D symbologies, governed by standards like ISO/IEC 15415, allow for error correction and are particularly useful in space-constrained packaging environments. RFID tags represent an advancement over optical barcodes by enabling wireless, non-line-of-sight reading, which facilitates bulk scanning in warehouses and distribution centers. Passive RFID tags, which lack an internal power source and are powered by the reader's , offer short read ranges of 1 to 10 meters and low costs ranging from $0.08 to $0.50 per tag, making them suitable for high-volume applications. Active RFID tags, powered by batteries, provide extended ranges up to 100 meters and support real-time data transmission but at higher costs of $12 to $45 per tag, ideal for tracking high-value or time-sensitive shipments. NFC and smart labels build on RFID principles with contactless chips that enable quick, proximity-based reads, often integrating sensors for enhanced functionality. These labels, compliant with ISO/IEC 14443 for NFC, allow users to tap a for instant data access and are increasingly combined with IoT sensors to monitor package conditions, such as fluctuations via embedded thermistors. In the 2020s, such smart labels have gained traction in logistics, where NFC-enabled sensors provide real-time alerts to prevent spoilage of perishables. These labeling technologies are applied through printed labels, adhesive stickers, or embedded tags directly integrated into packaging materials, ensuring seamless attachment during manufacturing or fulfillment. Durability is a key consideration, with standards requiring labels to withstand extreme conditions, including temperatures from -40°C to 60°C, as well as and mechanical stress common in global transit. Adoption of advanced labeling, particularly RFID, has surged in , with the global RFID market growing from approximately $6.5 billion in 2010 to USD 12.61 billion in 2025, reflecting increased integration for automated inventory and tracking efficiency. This expansion, driven by cost reductions and standardization, has elevated RFID usage in supply chains from niche applications, with ongoing growth in major operations as of 2025.

Tracking Methods

Manual and Barcode-Based Methods

Manual and barcode-based methods represent the foundational approach to package tracking, relying on human operators to scan visual barcodes at predefined checkpoints using handheld devices. These scanners, typically or image-based, capture the encoded from labels affixed to packages, which is then transmitted wirelessly or via cable to a central database for logging status updates such as location and handling events. This process occurs at key facilities including sorting hubs, transportation vehicles, and final delivery points, enabling sequential tracking without continuous monitoring. The workflow involves multiple discrete scans per package to record its progression through the . Operators scan barcodes upon receipt at the origin facility to confirm intake, during transit points such as customs clearance at airports for international shipments, and at the destination for sorting and delivery confirmation. Depending on the route complexity, a package may undergo several scans—commonly between five and fifteen—to provide a trail of custody, with each scan updating the database in near real-time to reflect the package's current status. These methods achieve high accuracy, often exceeding 99% success rates when using error-checking algorithms inherent to symbologies, which detect and correct read errors through in the code structure. However, limitations arise from the need for direct line-of-sight between the scanner and , as well as potential human factors like or misalignment, leading to misread rates of approximately 1-2% in practical environments. Such errors can result in delayed updates or rerouting but are mitigated by rescanning protocols. A prominent example is the United States Postal Service's (IMb), implemented in 2006 to enhance tracking for domestic mail by encoding routing, tracking, and service data into a single 65-bar code. The IMb allows automated sorting and piece-level visibility, replacing earlier POSTNET and barcodes, and has become mandatory for certain mail classes to support detailed deliverability reporting. Globally, barcode-based tracking is integral to parcel delivery, forming the basis for over 130 billion annual shipments by 2020 across major markets, with widespread adoption in express for status updates and bottleneck identification. The cost-effectiveness of these methods stems from their simplicity, primarily driven by low hardware requirements like handheld scanners priced between $100 and $300 each. Nonetheless, the approach remains labor-intensive, as it depends on manual intervention at each scan point, increasing personnel costs in high-volume operations despite the inexpensive technology.
