ETSI algorithms & codes service assigns and manages codes for various technologies. These codes are used by the communications industry to convey information about systems and equipment.

The administrative cost for each single code is €150 (VAT excluded / administrative fees included).

Customers wishing to purchase codes must sign a Confidentiality Usage Undertaking form (CRUU) and demonstrate they fulfil the specified approval conditions.

ETSI’s Centre for Testing and Interoperability (CTI) also assigns and registers codes for ETSI Technical Bodies. These specific codes do not require any of the specific approval conditions of the CRUU, nor do they involve any payment.

How to order a code

This is a two step process. The order is separate from the payment.

Protocol Naming and Numbering Service

ETSI’s Centre for Testing and Interoperability (CTI) assigns and registers ASN.1 object identifiers, protocol numbers, XML and URI namespaces, etc. for all ETSI Technical Bodies (TBs). ETSI CTI also allocates CNI codes for the broadcast industry.

Many protocols require the allocation of globally unique names or numbers in order to interoperate successfully. Ranges of names or numbers are often allocated to standards bodies in order to distribute the task of allocation, while still maintaining global uniqueness. 

In addition, ETSI CTI can manage, on behalf of an ETSI TB, a request for a protocol name or number allocation from another issuing authority. For example, allocations of Network Management Parameters or allocations for Diameter, XCAP, H.248 protocols can be managed.

All details related to these codes can be found on the Protocol Naming and Numbering page on the ETSI Portal.

To request one of these codes, please contact CTI_Support@etsi.org
