The PDR (Punto di Riconsegna, Redelivery Point) is the 14-digit code that identifies the point where the distribution network delivers gas to the customer's installation. For a business it is the key to every operation on the supply: without the correct PDR you cannot request an offer, switch supplier or transfer a contract. And a company with several sites has as many PDRs as it has connected points.
How the code is built
The structure is set by ARERA, the Italian energy regulator (resolution 138/04, article 5): a numerical code, unique at national level.
| Position | Digits | Meaning |
|---|---|---|
| 1-4 | 4 | Code of the distribution company active on the point at the time of coding, assigned by ARERA |
| 5-14 | 10 | Point number, unique for the distribution company that coded it |
The rule does not provide for check digits. The code is assigned by the local distributor, not by the supplier.
What does not change and what does
The PDR identifies the point, not the customer: it stays the same when you switch supplier and when the contract holder changes. It also remains unchanged if another company takes over the management of the network: this is why the first four digits may not match today's distributor. What does change is the supplier, the customer code each supplier assigns and the meter serial number, which identifies the device and is replaced along with it.
PDR and REMI: two different points of the network
Gas reaches the local network from a delivery point: the point where the transmission network hands it over to the distribution system. The REMI code identifies this upstream point; the PDR identifies the downstream point, at the boundary between the distribution network and the customer's installation. Many PDRs in the same area depend on the same REMI.
Resolution 138/04 requires the supplier to show on the invoice both the PDR and the code of the delivery point feeding the system. End customers connected directly to the transmission network, without going through a distributor, are a separate case: at the end of 2025 there were 5,539 of them (ARERA data) and their redelivery point belongs to the transmission operator's network.
The technical data linked to the PDR
On the bill, together with the PDR, the technical characteristics of the supply are shown (ARERA's billing rules require them for points below 200,000 Smc a year; above that threshold it depends on the supplier):
- Meter class: the letter G followed by a number (G6, G10, G25). It indicates the size of the meter and affects what is paid for distribution.
- C coefficient: it converts the cubic metres measured by the meter into standard cubic metres (Smc), the billing unit, referred to 15 °C and 1,013.25 millibar.
- Gross calorific value (P): the energy contained in one Smc of the gas distributed in the locality, in GJ/Smc. It is needed to move from prices in energy to prices in volume (see how the PSV price is formed).
- Customer type: for a business, "non-household uses".
At the end of 2025 electronic metering units numbered about 21.2 million out of 24.3 million (ARERA): where the meter is a traditional one, reading still requires an on-site visit or a self-reading.
For a business: what to look at
- A register of PDRs: for each point, code, address, REMI, distributor, meter class and serial number, annual consumption, supplier and contract expiry. It is what suppliers ask for in order to make an offer and what allows several sites to be put out to tender together.
- In the contract: the list of PDRs must be complete and correct. A forgotten point does not follow the others into the new contract.
- On the invoice: PDR, REMI, meter class, C coefficient and P should be checked at least on the first bill of every new supply and after every meter replacement.
- The decisions it affects: aligning the expiry dates of the different points, closing those no longer in use (an active PDR pays fixed charges even with no consumption), checking that the meter size is consistent with actual consumption.
- Typical mistakes: giving the meter serial number or the customer code instead of the PDR; not updating the register after acquisitions, relocations or department closures; assuming that neighbouring sites depend on the same distributor.
In 2025, 19.9% of "other uses" customers switched supplier (ARERA): switching affects neither the PDR nor the meter. Putting supply points in order is the first step of our gas consulting for businesses; for prices, the references are on the Market indices page.
