ETSI numbering system for ETSI Deliverables

You will find below information on the structure of ETSI document numbering. 

Annex B of the ETSI Technical Working Procedures of the ETSI Directives provide the same information in a different manner.

ETSI Deliverable numbering follows a structured format, which can be understood by breaking down its components:

1. Document Type

The first two letters in the filename indicate the Deliverable type. Here are the key types:

  • EG: ETSI Guide
  • EN: ETSI European Standard
  • ES: ETSI Standard
  • GR: ETSI Group Report
  • GS: ETSI Group Specification
  • TS: ETSI Technical Specification
  • TR: ETSI Technical Report
  • SR: ETSI Special Report

Older Deliverable types (pre-2015) may also appear, like ETS, I-ETS, or GTS (for GSM-related specs). See the table at the end of this page for further details.

2. Deliverable Number

The Deliverable number follows the type and is separated by an underscore. Each type starts with a specific number:

  • SRs: Start with 0
  • TRs and TSs: Start with 1
  • EGs and ESs: Start with 2
  • ENs: Start with 3
  • GSs: Start with their ISG name (e.g., "QKD" for Quantum Key Distribution).

3. Parts and Sub-parts

If the Deliverable has multiple parts, the part numbers follow the main number:

  • Part 1: Example: en_30116501
  • Sub-part 4: Example: en_3011650104

4. Version Number

The version number is shown after the letter "v" in the filename. For example, "en_30116v020202" for "EN 301 116 V2.2.2".

5. Procedure Code

The process the deliverable has gone through is indicated by codes like:

a:    Enquiry + Vote [under EN Approval Process – ENAP]

ev:    Enquiry + Vote [under Standardisation Request deliverable Approval Process – SRdAP]

m:     Vote [under Membership Approval Process – MAP]

v:     Vote [under EN Approval Process – ENAP]

va:    Vote [under Standardisation Request deliverable Approval Process – SRdAP]

p:     Publication

w:     Withdrawn

Example: eg_200351v020202a.pdf indicates the document was sent on Enquiry + Vote under ENAP.

6. Electronic Attachments

If the deliverable has attachments, they are packaged in a ZIP file, with a "0" added after the phase code.

  • Example: en_301165v010101c0.zip.

Examples of Document Filenames:

  • eg_200351v020202p.pdf → EG 200 351 V2.2.2 - published
  • en_30005206v010301ev0.zip → EN 300 052-6 V1.3.1 - sent on Enquiry + Vote under SRdAP
  • gsmts_0293sv050400w.pdf → GSM 02.93 V5.4.0 - withdrawn version
