Each company that takes out an DDEX Implementation Licence will be allocated a DDEX Party Identifier DPID in accordance with the DPID standard. Therefore each company that sends or receives DDEX messages will have been allocated a DPID. Therefore it is always possible to identify sender and recipient of a DDEX message through their DPID.
Companies that do not send or receive DDEX messages themselves may also be allocated DPIDs if they work with a technical service provider that does the DDEX messaging on their behalf. Therefore it is also possible to identify the "endpoints" of any data flow facilitated by a DDEX Message.
Some companies may even "own" more than one DPID. More information on this can be found here.
DPIDs, when used in a DDEX Message, do not have hyphens. The hyphens are solely for human readability. More information on the DPID syntax can be found here.
The allocation of DPIDs is done through an automated system at dpid.ddex.net. Upon filling in the form and submitting (wich includes accepting DDEX's Implementation Licence), the system will automatically send the applicant its DPID and credentials to allow look-up access to the DPID Registry.
When logging into dpid.ddex.net with the username and password provided, the user can view the complete DPID registry or search for a specific company or DPID. It is also possible to export the complete registry in PDF or XML format. The only information shown to users are: DPID, company name and company's street address.
Alternatively a user can call the DPID web server at the following address:
http://dpid.ddex.net/extractXML.php?u=UUUU&p=PPPP with UUUU and PPPP being the username and password provided to each DPID "owner". The system replies automatically with the XML formatted DPID registry.
All "owners" of DPIDs can – and should – keep their record up to date by logging into the system and changing any relevant information.
All "owners" of DPIDs can request additional DPIDs. Please note that when doing so, you must choose a different "company name" to indicate the difference between the various DPIDs to be allocated to your company. For example:
