The barcode is an integral part of the label and must be designed to meet Canada Post's requirements for both content and physical appearance. The label is typically printed on envelopes, packages, or items that are being mailed, and it is designed to be read by Canada Post's automated sorting equipment. |

|
2. Understanding the Components of a PostBar Label |
Before beginning the design process, it is crucial to understand the key components of a PostBar barcode label. These elements will guide the overall design and layout of the label, ensuring that it meets all necessary specifications. |
2.1 Barcode Area |
The PostBar itself is typically a 2D barcode, which means it is capable of storing a significant amount of information in both the horizontal and vertical dimensions. The barcode typically includes several data fields: |
Postal Code: The most critical element of the address, allowing Canada Post to determine the destination sorting facility. |
Tracking Number: A unique identifier assigned to each package or item, used for tracking the status and location of the mail item. |
Service Information: Specific details about the type of service being used (e.g., express mail, insured, registered). |
Sender and Recipient Addresses: These are encoded in a compressed format to make the most efficient use of space within the barcode. |
2.2 Human-Readable Information |
In addition to the barcode, the label also contains human-readable information that corresponds to the encoded data. This includes: |
Sender's Address: The full address of the sender, including name, street address, city, province, and postal code. |
Recipient's Address: The same details for the recipient, which may include name, address, city, province, and postal code. |
Tracking Number: The number displayed in text form, so customers and postal employees can easily refer to the specific item being tracked. |
2.3 Label Layout |
The layout of a PostBar label must be organized in a way that prioritizes the readability of the barcode, human-readable information, and the overall organization of the elements. The design should allow for easy scanning, whether through automated systems or manual handling by postal workers. The layout should also ensure that the label fits the typical sizes of envelopes or packages. |
2.4 Additional Information |
Depending on the service and the type of mail being sent, the label may include additional elements such as: |
Return Address: A section for the sender's return address. |
Postage Information: Stamps, postage meters, or labels indicating the postage paid. |
Handling Instructions: Special instructions or classifications, such as 'fragile' or 'do not bend,' may be added to the label. |

|
3. Step-by-Step Process for Designing a PostBar Barcode Label |
Designing a PostBar label involves several key steps. Below is a detailed guide on how to approach each of these steps to ensure a successful design. |
3.1 Step 1: Gather Information |
Before you begin the design, it is essential to gather all the relevant information that will be included in the label. This includes: |
The sender's and recipient's address details. |
The tracking number (which should be unique for each package or mail item). |
The service type being used (e.g., regular, express, insured). |
Any additional instructions or postage information. |
Once all this data is collected, you can begin to plan the structure of the barcode and the label. |
3.2 Step 2: Barcode Design |
The PostBar is a 2D barcode, which means it stores data in both dimensions-horizontally and vertically. To design the barcode, follow these steps: |
Choose a Barcode Symbology: PostBar utilizes a two-dimensional barcode format that can be read by Canada Post's automated systems. The most common type is a matrix barcode, which allows for the efficient encoding of a variety of data fields. |
Encode the Data: Using specialized barcode generation software, encode the data into the appropriate format. The following information should be included: |
Postal code |
Tracking number |
Service information (e.g., express, insured, registered) |
Sender and recipient address (in compressed format) |
Verify the Barcode: It is critical to verify that the barcode can be read accurately by barcode scanners and sorting systems. Use a barcode verification tool to test the clarity and quality of the barcode image before printing it. |
3.3 Step 3: Label Design |
With the barcode ready, you can now focus on designing the rest of the label. This step involves arranging the elements of the label in a clean, organized, and readable manner. |
Label Dimensions: Ensure that the dimensions of the label match the typical sizes for mailing in Canada. Labels can vary in size, but the most common are 4' x 6' or 6' x 4'. |
Positioning of Elements: The barcode should be placed in a central location on the label, with enough white space around it to avoid clutter. Ensure that the human-readable text (sender and recipient addresses, tracking number, etc.) is placed below or next to the barcode. |
Fonts and Readability: Use a standard font for the human-readable text (such as Arial or Times New Roman) to ensure clarity. Ensure that the font size is large enough to be legible, typically around 8-10 point. |
Include Mandatory Information: The following fields must be included on the label: |
Sender's name and address |
Recipient's name and address |
Tracking number |
Postal code |
Any handling instructions or service type |
3.4 Step 4: Testing and Prototyping |
After the initial design is complete, it is important to conduct thorough testing to ensure the label meets all functional requirements. This includes: |
Barcode Scanning: Test the label with a barcode scanner to ensure the encoded data is correctly read. This is essential for ensuring the success of the sorting and tracking process. |
