Frequently Asked Questions
Polish phone numbers are 9 digits long, excluding the +48 country code for international calls. They follow specific formats depending on whether they are landlines, mobile, toll-free, premium rate, shared cost, or VoIP numbers. For example, landlines use the format xx xxx xx xx within Poland and +48 xx xxx xx xx internationally.
You can validate Polish mobile numbers using regular expressions that check for the correct 9-digit format and prefixes. The article provides examples in TypeScript and Python. Remember to remove spaces and special characters before validation.
The Office of Electronic Communications (UKE) regulates Poland's telecommunications sector, enforcing regulations, ensuring compliance, and promoting competition among providers. They oversee everything from number portability to consumer protection, as well as technical implementations involving Polish phone numbers.
To call a Polish landline from the US, dial 011 followed by 48 (Poland's country code), the 2-digit area code, and the 7-digit subscriber number. For example, to call Warsaw (area code 22), you would dial 011 48 22 xxx xx xx.
Premium rate numbers are subject to regulations regarding pricing transparency, maximum call duration, and mandatory cost disclosures to protect consumers from unexpected charges. These regulations are defined in the Telecommunications Act overseen by the UKE.
Poland has several phone number categories, including geographic (landlines), mobile, toll-free, premium rate, shared cost, and VoIP. Each type has a specific format and prefix, which are detailed in the article with examples.
Number portability in Poland allows users to keep their phone number when changing service providers. Managed by the UKE, the process typically takes one working day with minimal service interruption. The country has a high porting success rate of over 98%.
The article provides a table of common area codes including 22 for Warsaw, 12 for Kraków, 71 for Wrocław, 58 for Gdańsk, 61 for Poznań, 42 for Łódź, 32 for Katowice, and 81 for Lublin.
Dial 00 48 followed by the 9-digit mobile number. For instance, to call the number 601 123 456 you would dial 00 48 601 123 456.
Regularly update your validation rules to reflect changes in numbering plans and regulations. Also, make sure your validation process can handle various formats, including those with and without the country code (+48).
When implementing systems interacting with Polish phone numbers, consider infrastructure like network capacity and redundancy, reliability measures like high uptime and failover systems, and security measures like DDoS protection and call encryption.
Poland's Electronic Communications Law (ECL) and other regulations focus on consumer protection, mandating cost transparency, simplified contract summaries, easier termination rights, complaint resolution procedures, and strict data protection aligned with GDPR.
Yes, VoIP numbers are available in Poland, starting with the prefix 39. Implementations must adhere to UKE-defined technical standards like SIP protocol usage, QoS monitoring, failover support, and emergency service routing.

Poland Phone Numbers: Format, Area Code & Validation Guide
This guide provides a comprehensive overview of Poland's phone number system, including formatting, area codes, validation, and the regulatory framework overseen by the Office of Electronic Communications (UKE). Whether you're a telecommunications professional, system administrator, or developer integrating with Polish systems, understanding these details is crucial for successful communication.
Regulatory Framework
Poland's telecommunications sector is governed by the Telecommunications Act of 2004, which outlines the principles for conducting telecommunications activities, rights and obligations of operators and users, market regulation, universal service provision, consumer protection (including privacy and confidentiality), and resource management (numbering, frequencies, and orbital resources). This framework aims to foster competition, promote infrastructure development, and ensure user benefits in terms of choice, price, and quality of services. The UKE plays a central role in enforcing these regulations and ensuring compliance. Recent amendments, such as the Electronic Communications Law (ECL) effective November 10, 2025, further modernize the framework, extending its scope to online communication services and strengthening consumer protection measures.
Number Formatting and Categories
Polish phone numbers are 9 digits long, excluding the country code (+48) for international calls. They are categorized into several types:
1. Geographic Numbers (Landlines)
xx xxx xx xx
(within Poland),+48 xx xxx xx xx
(international)22 123 45 67
. To call this number from the US, you would dial011 48 22 123 45 67
.Here's a table of common area codes:
2. Mobile Numbers
xxx xxx xxx
(within Poland),+48 xxx xxx xxx
(international)601 123 456
. To call this number from the UK, you would dial00 48 601 123 456
.3. Toll-Free Numbers
800 xxx xxx
(within Poland),+48 800 xxx xxx
(international)800
, followed by a 6-digit subscriber number.800 123 456
4. Premium Rate Numbers
70x xxx xx xx
(within Poland),+48 70x xxx xx xx
(international)70
, followed by a digit indicating the rate tier (1-3: standard, 4-6: enhanced, 7-9: premium), and then a 7-digit subscriber number.703 123 45 67
5. Shared Cost Numbers
801 xxx xxx
(within Poland),+48 801 xxx xxx
(international)801
, followed by a 6-digit subscriber number.801 123 456
6. VoIP Numbers
39x xxx xxx
(within Poland),+48 39x xxx xxx
(international)39
, followed by a 7-digit subscriber number.391 123 456
Number Validation
Validating Polish phone numbers is essential for ensuring data integrity and preventing communication errors. Here are some examples using regular expressions and code:
Best Practice: Regularly update validation rules to reflect changes in numbering plans and regulations.
Number Portability
Number portability, managed by the UKE, allows consumers to retain their phone numbers when switching service providers. This process typically takes one working day with minimal service interruption (up to 3 hours). Poland boasts a high porting success rate (over 98%), fostering competition among operators. The system relies on a centralized database with real-time synchronization and standardized APIs for seamless transfer between providers.
Consumer Protection
The ECL and other regulations prioritize consumer protection. Key measures include:
Non-compliance with these regulations can lead to penalties and service suspension.
Technical Implementation Guidelines
Implementing systems that interact with Polish phone numbers requires attention to infrastructure, reliability, and security:
This guide provides a solid foundation for understanding and working with Polish phone numbers. Always refer to the official UKE website and the latest regulations for the most up-to-date information.
