The Facing Identification Mark (FIM) barcode is a unique type of barcode primarily used by postal services for automated mail sorting and processing. |
Here's a detailed exploration of its components and structures: |
|
Components of Facing Identification Mark (FIM) Barcode: |
1.Barcode Type and Standards: The FIM barcode is categorized under the PLANET (Postal Alpha Numeric Encoding Technique) and POSTNET (Postal Numeric Encoding Technique) barcode standards. It is used by postal services globally, including the United States Postal Service (USPS) and other international postal organizations. |
2.Encoding Method: FIM barcodes are typically binary barcodes, meaning they consist of bars and spaces arranged in a specific pattern to encode numeric or alphanumeric information. They encode specific routing and sorting information related to the mail piece. |
3.Orientation and Placement: FIM barcodes are printed in a vertical orientation and are placed in the upper right corner of the mail item, adjacent to the postage stamp or meter imprint. This placement allows automated sorting machines to quickly read and process the barcode information. |

Structure of Facing Identification Mark (FIM) Barcode: |
1.Format and Dimensions: The FIM barcode consists of a series of vertical bars (black) and spaces (white) arranged in specific patterns. It typically spans a height of approximately 0.625 inches (15.875 mm) and can vary slightly in width depending on the encoding scheme. |
2.Encoding Patterns: There are several encoding patterns used within FIM barcodes, denoted as FIM A, FIM B, and FIM C. Each pattern serves a different purpose, such as identifying the class of mail, providing routing information, or indicating special services. |
3.FIM A Pattern: FIM A is the simplest pattern and consists of a single bar followed by a single space. It is used for identifying automation-compatible letters and flats in the mail stream. |
|
Example: |
Pattern: 101 Interpretation: Indicates automation-compatible mail. |
4.FIM B Pattern: FIM B includes two bars followed by two spaces. It is used for identifying non-automation-compatible mail pieces or as an additional service indicator. |
Example: |
Pattern: 11001100 Interpretation: Indicates non-automation-compatible mail or a special service indicator. |
5.FIM C Pattern: FIM C is a combination of bars and spaces that encode more complex information, such as specific ZIP codes or delivery point routing. It is used for higher-level sorting and routing purposes. |
Example: |
Pattern: 1000111000011100 Interpretation: Encodes detailed routing or delivery point information. |
6.Error Detection and Correction: FIM barcodes may include error detection and correction mechanisms to ensure accuracy in reading and processing. This typically involves check digits or parity bits embedded within the barcode data. |
|
Usage and Examples: |
USPS Example: In the United States, the USPS uses FIM barcodes extensively on all classes of mail, including letters, flats, and parcels. The FIM barcode helps in sorting mail by directing it to the correct destination based on ZIP code and other routing information. |
International Application: Many international postal services have adopted variations of FIM barcodes or similar encoding techniques to facilitate automated mail processing and improve efficiency. |
|
Conclusion: |
The Facing Identification Mark (FIM) barcode is a critical component of automated mail sorting systems used by postal services worldwide. Its structured format, consisting of vertical bars and spaces arranged in specific patterns (FIM A, FIM B, FIM C), enables quick and accurate identification of mail types, routing information, and special services. Understanding the components and structures of FIM barcodes is essential for ensuring efficient mail processing and delivery within postal networks. |
This detailed exploration provides insight into how FIM barcodes are designed, encoded, and utilized, showcasing their importance in modern postal operations. |
