ETSI numbering system for documents

You will find below information on the structure of ETSI document numbering. Annex C of the ETSI Technical Working Procedures of the ETSI Directives provide the same information in a different manner.

These are examples of what you will see when downloading an ETSI standard.

Detailed explanation

The first two letters represent the deliverable type:

To distinguish the deliverable type from the deliverable number an underscore "_" is placed between them.

• All the SRs start with the number "0"
• All the TRs and TSs start with the number "1"
• All the EGs and ESs start with the number "2"
• All the ENs start with the number "3"
• All the GSs start with the three letters corresponding to the ISG name e.g. "QKD"

The deliverable might be composed of several parts and sometimes also sub-parts.

In this case the part's number is indicated just after the deliverable number

EXAMPLES:
EN 301 165 Part 1 » en_30116501.

EN 301 165 Part 1 Sub-part 4 » en_3011650104.

The number following "v" is the version number.

EXAMPLE:
eg_200351v020202p.pdf  »  EG 200 351 V2.2.2.

The procedure the deliverable has been sent on is shown by a code:

EXAMPLE:
eg_200351v020202a.pdf  »  sent on approval procedure.

Electronic attachments are contained in a ZIP file. This file has the same number as the deliverable to which it is attached but with a "0" (zero) placed after the phase code.

EXAMPLE:
en_301165v010101c0.zip
