The Polish Driving Licence (PL-DL) is an official document that has undergone a series of transformations to harmonize with European standards, in line with the requirements of the European Union Directive 2006/126/EC. The document confirms the holder's authorization to drive specific categories of vehicles within the European Economic Area (EEA) and beyond.
A crucial element of the PL-DL is the Driving Licence Number (NPJ) (Numer Prawa Jazdy). Understanding where the driving licence number is and what its function is, is of fundamental importance to every driver. We must distinguish between the NPJ, which is the driver's permanent legal identifier within the system, and the Document Number (ND) (Numer Druku), which identifies only the physical carrier.
It is worth noting that an amendment introduced on March 4, 2019, removed the residential address information from the physical document. This change significantly simplified formalities, eliminating the need to exchange the driving licence upon every change of residence or address, thereby reducing bureaucratic burdens.
Location and Identification Structure of the Polish Driving Licence (PL-DL)
The Polish driving licence follows a unified credit card format. The structure of the document is strictly defined, and specific fields on the obverse (front side) and reverse (back side) contain detailed information about the driver and their entitlements.
Physical Structure and Obverse Elements
The obverse of the document contains personal and administrative data necessary for identification:
- Positions 1, 2, 3: Surname, First Name(s), and Date and place of birth of the holder.
- Positions 4a, 4b, 4c: Detailed dates, including the date of issue of the driving licence (4a), the date of expiry of the document (4b), and the name of the public administration authority that issued the document (4c), which is usually the Starosta (District Governor) or City President.
- Position 4d: PESEL number, which is the national digital identifier of the physical person.
- Position 6 and 7: Photograph and signature of the document holder.
Answer to the Main Question: Where Is the Driving Licence Number (NPJ)?
The primary identifier of the driver's entitlements and record - this is the Driving Licence Number.
The Driving Licence Number (NPJ), which is the essential identifier for entitlements and the driver's record, is located on the obverse of the document, in the section marked with the digit 5. It is geographically located directly next to the holder's photograph. This driving licence number serves to uniquely identify the driver in the context of their driving history, penalty points, and entitlements in the Central Register of Drivers (CEK).

If you are asking yourself where can I find the driving licence number or DL number, look for the digit 5 - that is where your unique number on the driving licence is located. Knowing this is necessary for many formalities.
NPJ (Pos. 5) vs. Document Number (ND): Key Distinction and Functions
The distinction between the Driving Licence Number (NPJ, Pos. 5) and the Document Number (ND) is crucial for understanding the architectural structure of the document and the administrative systems that support it. These are two separate elements with completely different functions.
Function of the Driving Licence Number (NPJ)
The Driving Licence Number (Pos. 5) is the primary, unique key that identifies the specific driver's record in the Central Register of Drivers (CEK).
- Identity and Entitlement Verification: It is used for identity verification during online transactions and administrative formalities, such as vehicle registration, insurance, and verification of entitlements for various legal purposes.
- System Applications: Insurance companies use it to assess the driver's experience and history for risk calculation. It is the core identifying key of the driver in the Central Register of Drivers.
Function of the Document/Blank Number (ND)
The Document Number, also referred to as the Blank Number, performs primarily an administrative and security function. Its task is to ensure the uniqueness of the physical document blank and enable the issuing authority (i.e., the Polish Security Printing Works and Communication Departments) to track the series of physical cards issued.
- ND Location on PL-DL: It is located on the reverse (back side) of the document, usually placed under the barcode.
- This number is not used to identify the driver during roadside checks or to check for penalty points. It has a logistical and security significance.
Critical Legal Implication: Change upon Duplicate Issue
The fundamental distinction is that the NPJ identifies the person and their entitlements, while the ND identifies the physical carrier of those entitlements.
This separation has critical implications in managing the driver's history, especially in case of document loss. When a duplicate (wtórnik) is issued:
- The Driving Licence Number (NPJ) usually remains unchanged, to maintain the historical continuity of the driver's record in the CEK.
- The Document Number (ND) must change, as a new physical document blank is being issued.
This architecture of data security ensures that the loss of the physical document does not compromise the stability of the driver's main identifier.
| Feature | Driving Licence Number (NPJ, Pos. 5) | Document/Blank Number (ND) |
| Location on Document | Obverse, next to the photo | Reverse, under the barcode |
| Main Function | Identification of driver and their entitlements in CEK | Identification and security of the physical blank |
| Practical Use | Insurance, online identity verification, CEK | Logistics of document issuance by PWPW |
| Change upon Duplicate | Usually remains the same (permanent identifier) | Changes (new physical carrier) |
| Required for Check | YES (identification of driver's entitlements) | NO (not used for roadside checks) |
Systemic Application of NPJ: Entitlement Verification and Administrative Simplifications
In a driver's daily life, the Driving Licence Number is used much more frequently and for more important purposes. Knowing the answer to the question where the driving licence number is located is crucial.
Historical Verification: Central Register of Drivers (CEK)
The Driving Licence Number is the primary, unique key identifying the specific driver's record in the Central Register of Drivers (CEK). Through the CEK system, a driver can check their own legal status and history.
Access to online services on the Gov.pl portal requires authentication using a Trusted Profile (Profil Zaufany). This service is free of charge and allows for the immediate display of the current number of penalty points, although it is only accessible to the account holder. It is also possible to check one's own driving entitlements.
Access to NPJ without the "Plastic": mObywatel
The loss of the physical document does not mean the driver loses access to their unique Driving Licence Number (DL number, Pos. 5). Thanks to the digitization of public services, the NPJ can be easily recovered without the need for a visit to an office.
The entitlement holder can verify their NPJ online free of charge by logging into government systems, such as mObywatel, using a Trusted Profile. The mObywatel mobile application offers mPrawo Jazdy (mobile driving licence), which in Poland is equivalent to the physical document. It displays all key data, including the driving licence number and entitlement categories.
An important element is the introduced temporary driving licence, which is a digital document valid for 30 days from the moment of passing the state driving exam (for selected categories, including A, B, B+E). This is an innovative solution that drastically shortens the waiting time for the issuance of the physical "plastic."
Comprehensive Overview of Categories, Validity Periods, and Restrictions (EU Codes)
Overview of Key Categories and Minimum Ages

Categories are divided into non-professional and professional:
- Category A: Entitles the holder to drive all motorcycles. The standard age for obtaining it is 24 years, but it can be lowered to 20 years if the driver has held Category A2 for at least two years.
- Category B: Entitles the holder to drive passenger cars with a permissible total weight (DMC) of up to 3.5 tonnes. The minimum age is 18 years. Category B also allows driving vehicles up to 4.25 tonnes, provided they are powered by alternative fuels.
- Categories C and D (Professional): Category C (trucks > 3.5t) and D (buses) generally require a minimum age of 21 years. However, there is a possibility of lowering the minimum age to 18 years for Category C and C1 and to 21 years for D1, if the candidate has completed the so-called initial qualification.
- Category T: Entitles the holder to drive agricultural tractors and slow-moving vehicles. It can be obtained as early as 16 years of age.
Validity Policy and Entitlement Duration (Pos. 4b)
The maximum validity period for a driving licence varies:
- Maximum 15 years: Applies to all non-professional categories (AM, A, A1, A2, B, B1, B+E, T).
- Maximum 5 years: Applies to all professional categories, including C, C1, C+E, C1+E, D, D1, D+E, D1+E.
The shortened, five-year validity period for professional categories directly results from the greater responsibility and risk associated with heavy goods and passenger transport. The shortening of the validity period is a deliberate public safety mechanism that requires professional drivers to undergo regular (every 5 years) specialized medical and psychological examinations.
Restriction and Requirement Codes (Pos. 12)
Field 12 on the driving licence document contains harmonized European Union codes that specify restrictions or requirements that the driver must meet. These codes constitute legally binding licence conditions.
Examples of codes:
- 01.01: Glasses required.
- 01.02: Contact lenses required.
- 01.06: Glasses or lenses required.
- 71: Duplicate (Wtórnik).
Violation of these codes is equivalent to driving a vehicle without valid entitlements, which in the event of a check or accident can result in severe legal sanctions, including fines of at least 1500 zł, with the possibility of increasing to 30 thousand zł in court proceedings, and an order prohibiting the driving of vehicles.
Administrative Procedures: Loss, Duplicate, and International Requirements
National Procedure: Obtaining a Duplicate (Wtórnik)
The procedure for exchanging a driving licence or obtaining a duplicate due to loss is unified. The application must be submitted to the Communication Department (Wydział Komunikacji) relevant to the driver's place of residence.
- Fee: Payment of the fee for issuing the document, which standardly amounts to 100 zł.
- Required steps: Completion of the formal application, attaching a color photograph of 35x45 cm, and the ID card for inspection.
- The matter can be handled in person or online, using a Trusted Profile.
In case of losing the driving licence, reporting the loss to the police is not mandatory unless there is certainty or suspicion that the document was stolen.
Procedure for Loss/Theft Abroad
In case of document loss abroad, it is necessary to immediately report the matter to the nearest police station in that country to obtain a certificate confirming the loss. Then, if necessary, contact with the Polish consulate or embassy is advisable. Upon returning to Poland, the driver submits an application for a duplicate to their Communication Department, following the national procedure.
International Application of the Driving Licence (MPJ)
When traveling outside the EEA, possession of an International Driving Permit (MPJ) is usually required, which must be used together with the original Polish driving licence.
- Vienna Convention (1968): The MPJ issued under it is recognized in numerous states, including Austria, France, Germany, the Czech Republic, and Brazil.
- Geneva Convention (1949): In countries that are parties to this convention and have not adopted the Vienna standards, an MPJ issued in a different, specific format is required.
Knowledge of this duality of formats is necessary to ensure the full legality of driving in different jurisdictions. The Republic of Poland has also concluded bilateral agreements on the mutual recognition of driving licences with selected countries, such as the Empire of Japan and the Republic of Korea. For information about the document and how to obtain it, please refer to the appropriate source for obtaining a new document.
Expert Conclusions: Document Management and NPJ
The analysis of the Polish driving licence indicates an advanced documentation and administration system that effectively separates the identification of the driver from the identification of the document carrier. The Driving Licence Number (NPJ) is the permanent legal and systemic key, critical for the driver's history in the CEK, while the Document Number (ND) performs logistical and security functions.
Monitoring the entitlement expiry date (Pos. 4b) is of fundamental importance. This is particularly critical for professional categories (C, D, C+E, D+E), where the maximum validity period is only 5 years. Regular renewal of entitlements, linked to required medical examinations, is crucial for the continuity of professional and legal mobility.
Entities relying on entitlement verification should always use the Driving Licence Number (NPJ) as the primary identification key to verify the driver's status in the CEK/mObywatel system, adhering to detailed legal regulations.
Finally, it must be emphasized that the restriction codes in Pos. 12 are legal conditions. The driver must strictly comply with these codes, as their violation constitutes a breach of the licence conditions, leading to serious financial and legal consequences.
