Polska Spółka Gazownictwa sp. z o.o. (PSG) is carrying out a change in the numbering of Output Points (PoDs) to numbering that complies with the GS1 system standard from June 2020. In 2020, the change of the PoD number was first applied to WR customers from all tariff areas and WS customers from the Zabrze and Gdańsk tariff areas, and then to WS customers from the Wrocław tariff area. For the remaining tariff areas, the POD re-numbering will take place in 2021, with PSG informing interested parties in advance of any further changes.

The GS1 System is an international set of identification and communication standards and business solutions developed by the international nonprofit organization GS1, an association of independent domestic organizations. GS1 Poland manages the GS1 System in Poland, supporting the participants in introducing standards in the country. Find out more at: https://www.gs1pl.org.

The PoD number is an example of a Global Service Relation Number ( GSRN). The identifier consists of 22 digits and is composed of the GS1 Company Prefix, the service relationship number, and the check digit. It constitutes a unique, unambiguous ID number for the service provider to store data related to the service or services provided to the customer.

Thanks to the introduction of GS1 numbering, the PoD identification system will be unified and the check digit will enable the number to be validated in IT systems upon entry, which will result in much more efficient detection and elimination of errors and mistakes. Meanwhile, by introducing identification based on a widely recognized international standard, IT systems will more easily be integrated with the use of standard mechanisms and tools, which means greater reliability and lower expenditure."

The change applies to the SAP system, which currently supports the all tariff areas and all WR and WS customers.

PSG will inform DSCs in advance about renumbering in the next tariff area, and then in the following message it will provide files with the old–new POD number mapping. The mapping files will be sent to each DSC individually and will contain data only for the renumbered PoD of a given DSC.

For technical reasons, after the migration date of a given tariff area, in the case of messages sent from and received by PSG, the POD number in the GS1 standard will the correct one. Therefore, adjustments to the meter readings from the period before the PoD renumbering will contain information about the PoD number in the GS1 standard.
