DD CEN/TS 15844 — Postal Services AIDA (Automation of Identification of Items) Series (Draft for Development)
Postal services — AIDA (Automation of identification of items) CEN/TS 15844 series (Draft for Development)
📮 DD CEN/TS 15844 is a Draft for Development published by the British Standards Institution (BSI), the UK implementation of the European technical specification CEN/TS 15844 series, which specifies Postal services — AIDA (Automation of identification of items). Prepared under the responsibility of BSI Technical Committee SVS/4 (Postal services), it covers general provisions, print specifications, machine readability, data and coding, and test methods, serving postal automated sorting, address recognition, and item tracking.
⚠️ Note: a DD (Draft for Development) is a provisional publication and is not a formal British Standard. BSI issues it in this form to gather practical application experience, and its status will be decided by CEN after the review period (conversion to an international/European standard, extension, or withdrawal).
1. Series Overview and Background 📌
With the growth of e-commerce and the global postal network, the ability to automate mail handling has become a core competence of postal operators. The CEN/TS 15844 series defines a framework for mail automation identification, and BSI implemented it in the Draft for Development form, creating the DD CEN/TS 15844 series. The series stays aligned with related ISO postal standards (such as mail barcode and identification systems).
The parts are independent yet interlinked: Part 1 specifies general provisions, Part 2 specifies print specifications, Part 3 specifies machine readability aspects, Part 4 specifies data and coding, and Part 5 specifies test methods. Together the parts support automated mail handling from acceptance, sorting, to delivery.
💡 The goal of AIDA (automation of identification of items) is to let identifiers printed on mail (such as barcodes and address codes) be read reliably by automated sorting equipment, reducing manual intervention and improving processing efficiency.
2. Series Structure and Technical Highlights 📋
| Standard | Part Title | Year | Key Technical Content |
|---|---|---|---|
| DD CEN/TS 15844-1:2010 | General provisions | 2010 | Overall framework, terminology, and references; AIDA system structure and interoperability requirements |
| DD CEN/TS 15844-2:2010 | Print specifications | 2010 | Print position, size, contrast, and background constraints of mail identifiers |
| DD CEN/TS 15844-3:2010 | Machine readability aspects | 2010 | Machine-readable identifiers, barcode symbology, and reading-performance requirements |
| DD CEN/TS 15844-4:2010 | Data and coding | 2010 | Format, coding rules, and data structure of identifier-carried data |
| DD CEN/TS 15844-5:2010 | Test methods | 2010 | Test and evaluation methods for identifier print quality and reading performance |
💡 The key to mail automation identification is a “unified identifier language”: consistent print specifications, barcode quality, and data layout let sorting equipment from different vendors read the same information.
3. Key Technical Requirements 🔧
3.1 General Provisions and System Structure
Part 1 specifies the overall framework and interoperability requirements of the AIDA system, clarifying the scope and references of each part and providing a consistent technical basis for mail automation identification.
3.2 Print Specifications and Machine Readability
Parts 2 and 3 set print specification and machine readability requirements for automated identifiers printed on mail, including position, size, print contrast, background constraints, and barcode symbology, ensuring identifiers are captured and recognized stably in high-speed sorting environments.
3.3 Data Encoding and Test Methods
Parts 4 and 5 specify the unified data and coding format for identifier-carried data (address codes, tracking numbers, etc.), and the test methods for identifier print quality and reading performance. Through standardized assessment procedures, print and coding quality is controlled to ensure high reliability and consistency of automated handling.
🚨 Implementation essentials: poor mail print quality (insufficient contrast, soiling, barcode distortion) directly affects sorting read rate; senders and print vendors should control quality per contrast and quiet-zone requirements to avoid delays.
4. Engineering Practice and Applications 🛠️
- 🔍 Postal operators: organize automated mail sorting and tracking per the series, improving processing efficiency.
- 🔧 Print vendors: produce mail identifiers per the print specifications, ensuring barcode and address-coding quality.
- 📊 Equipment makers: develop sorting and identification equipment meeting the identifier-reading requirements.
- 📋 E-commerce and bulk customers: print shipping labels per the unified identifier specification, improving delivery efficiency and trackability.
✅ Following the series significantly improves automated mail read rates, reduces manual and mis-sorting, and supports efficient, reliable postal and express services.
5. Frequently Asked Questions ❓
❓ Q: What type of document is a DD (Draft for Development)?
A: A DD is a provisional BSI development draft used to gather application experience before a formal standard is established; it is not a formal British Standard, and its status is decided by the relevant body after review.

❓ Q: Why do mail identifiers need a unified specification?
A: Unified print specifications and data coding let sorting equipment from different vendors read identifiers stably — the prerequisite for automated mail handling and cross-network exchange.

❓ Q: What is the impact of poor identifier quality?
A: Insufficient contrast, soiling, or barcode distortion makes sorting equipment unable to read the identifier; the item is downgraded to manual handling, increasing delay and cost.

🔍 Q: Who needs to follow these requirements?
A: Postal operators, print vendors, sorting-equipment makers, and bulk customers printing shipping labels should all follow them to guarantee end-to-end machine readability.
