How to Design Japan Post Barcode Label: A Comprehensive Guide |
Japan Post, the national postal service of Japan, uses specific barcode standards for efficient sorting, tracking, and delivery of parcels and mail items. Designing a Japan Post barcode label requires a clear understanding of the encoding system, label layout, and various technical specifications. This guide will provide a step-by-step overview of the process, from barcode generation to proper placement on labels, along with essential details on the components required to ensure compliance with Japan Post's standards. |

|
1. Introduction to Japan Post Barcode Standards |
Japan Post uses different types of barcodes depending on the service, such as the PostBar barcode and the QR code-based labels. These barcodes help streamline the sorting process and facilitate the tracking of mail and packages. The primary goal of these barcodes is to encode essential information for package delivery, such as sender details, recipient address, and tracking numbers. |
The barcode system in use by Japan Post follows the JAN (Japanese Article Number) standards for encoding information. This standard is compatible with the EAN-13 barcode system, making it interoperable with international shipping and tracking systems. |

|
2. Understanding the PostBar Barcode |
The PostBar barcode is specifically used by Japan Post for its various services, including regular mail, express mail, and packages. This barcode is different from standard linear barcodes and features a more compact design to encode greater amounts of data. The PostBar barcode typically encodes the following information: |
Tracking Number: A unique identifier for each item to be tracked. |
Sender Information: The name, address, and contact details of the sender. |
Recipient Information: The name, address, and contact details of the recipient. |
Service Type: Type of service used (e.g., registered, express, etc.). |
Other Metadata: Depending on the service, additional data such as delivery date or item weight might be encoded. |
This barcode is essential for ensuring that packages are correctly routed through Japan Post's sorting facilities and can be tracked at various stages of delivery. |

|
3. Barcode Format for Japan Post Label |
Japan Post utilizes several types of barcodes on their label designs. The two most commonly used are: |
1D Barcodes: Primarily used for simple encoding of the tracking number and basic sender/recipient information. |
2D Barcodes (QR codes): Used for more complex encoding, such as including the full address, delivery instructions, and tracking information. |
Barcode Size and Dimensions: The barcode's size depends on the type of information encoded and the physical dimensions of the shipping label. Japan Post labels typically have fixed height and width ratios to accommodate the barcode within the label layout. The size of the barcode is crucial for scanning accuracy and ease of processing. |
Height: Typically ranges between 20mm to 50mm. |
Width: Ranges from 100mm to 150mm for 1D barcodes, while 2D barcodes can range up to 40mm in both dimensions. |

|
4. Steps in Designing the Japan Post Barcode Label |
4.1. Gather Necessary Information |
Before starting the design of the barcode label, the following pieces of information need to be gathered: |
1.Sender's Information: Name, address, postal code, and contact number. |
2.Recipient's Information: Name, address, postal code, and contact number. |
3.Tracking Number: A unique alphanumeric string that will be used to track the item. |
4.Service Type: The specific service selected for the shipment, such as standard mail, registered mail, or express delivery. |
5.Delivery Instructions (optional): Special requests or instructions for the delivery process. |
4.2. Choose Barcode Type |
Japan Post allows for the use of 1D and 2D barcodes, depending on the complexity of the information that needs to be encoded. For a more basic design, a 1D barcode might suffice, whereas for more information-heavy shipments, a 2D barcode (QR code) may be necessary. |
For simple shipments: A 1D barcode encoding the tracking number and service type is sufficient. |
For more complex shipments: A QR code should be used to encode both tracking and recipient details, along with any special instructions. |
4.3. Determine Label Dimensions |
The dimensions of the label are a critical aspect of the design, ensuring compatibility with Japan Post's sorting machinery. The typical dimensions for Japan Post barcode labels are: |
Width: 100mm to 150mm |
Height: 60mm to 100mm |
These dimensions are large enough to accommodate both the barcode and textual information, such as sender and recipient details. |
4.4. Design Layout of the Label |
Once the information and barcode type are chosen, the layout can begin. A well-designed Japan Post barcode label generally includes: |
Header: This section should contain the Japan Post logo or the company's branding, as well as the service type (e.g., 'Express', 'Registered'). |
Sender and Recipient Information: These should be printed clearly with address and contact details in a legible font. |
Barcode Placement: The barcode should be placed prominently, typically near the bottom or the center of the label. |
Additional Instructions: If there are any delivery instructions or special notices, they should be placed in a box or highlighted area on the label. |
Tracking Number: This should be clearly visible next to or beneath the barcode. |
4.5. Barcode Encoding and Printing |
To ensure the barcode is generated correctly, the data needs to be encoded in the appropriate format. The tracking number and additional details such as sender and recipient addresses are converted into machine-readable code. |
For 1D Barcodes: Use a symbology such as Code 128 or Code 39, which are commonly used in Japan Post barcodes. |
For QR Codes: A QR code can be generated using an online tool or a specialized software library that converts the relevant data into the QR code format. |
The barcode should then be printed using high-quality printing methods to ensure that it is scannable by Japan Post's sorting equipment. Thermal transfer printers or direct thermal printing methods are commonly used to ensure durability. |
4.6. Quality Control and Testing |
Once the labels are designed and the barcodes printed, it is important to perform quality control checks. This step ensures the printed barcodes are scannable and that the label layout matches Japan Post's requirements. |
Scanning Tests: Use barcode scanners to test if the barcode can be read easily from different angles and distances. |
Print Quality: Check the print for clarity, resolution, and absence of smudges or distortions. Poor print quality can lead to scanning failures, causing delays or misdeliveries. |
Data Verification: Ensure that all data encoded in the barcode corresponds accurately to the shipping details. |

|
5. Barcode Standards and Specifications |
Japan Post barcode labels must adhere to strict formatting and encoding standards. Here are the key points: |
Font Size and Style: Japan Post recommends using easily readable fonts such as Arial or Helvetica for textual information. The font size should be large enough to be legible by both machines and humans, typically around 10pt to 14pt. |
Barcode Size: As mentioned, the barcode should be printed at a size that allows for easy scanning. A minimum height of 20mm and width of 50mm is often suggested for 1D barcodes, while QR codes should have a minimum size of 30mm x 30mm. |
Placement: The barcode must be positioned within a defined space on the label. It should not be too close to the edges or adjacent to other elements like logos or text. |
5.1. Data Encoding Rules |
Tracking Number: Japan Post assigns unique tracking numbers to all parcels and letters. The tracking number must be encoded in the barcode in a standard format that can be interpreted by Japan Post's systems. |
Sender and Recipient Information: This information is typically encoded as plain text or using a non-proportional barcode font. |
Service Type and Metadata: Certain services (e.g., express mail) may require additional metadata in the barcode. This data may be encoded in specific fields within the barcode. |

|
6. Label Printing and Application |
Once the barcode label is designed, printed, and verified for accuracy, it needs to be applied to the item being shipped. Care should be taken to ensure that the label is affixed to the package in a manner that ensures it is visible and scannable. |
Positioning: The label should be placed on the largest flat surface of the package. The barcode must be placed in a way that does not interfere with other shipping information or branding. |
Durability: Since packages are often exposed to harsh conditions during shipping, it is essential to use durable label materials. Thermal transfer labels with protective laminates are ideal for this purpose. |

|
7. Final Steps: Submission and Tracking |
After affixing the label to the parcel or letter, the package can be submitted for delivery. Japan Post's tracking systems will use the barcode to scan and log the package at various checkpoints, ensuring accurate tracking throughout the delivery process. |
Tracking Updates: The barcode will provide updates as the package progresses through the Japan Post network. Both the sender and recipient can check the status of the package using the tracking number encoded in the barcode. |
Compliance with International Shipping: Japan Post barcodes, including PostBar and QR codes, comply with international shipping standards, allowing them to be scanned and processed by global carriers if necessary. |
