Poland Address Generator

What It Is: A Data Tool for Generating Poland-Formatted Test Addresses

When developing an e-commerce website targeting Polish users, you might need to generate 500 correctly formatted dummy addresses to populate your test database. Manually piecing together "ul.", "al.", and "XX-XXX" postal codes is both tedious and prone to formatting errors. Our generator is built exactly for this scenario. Following actual Polish address formatting rules, it automatically outputs structured dummy addresses containing the province (Voivodeship), city, street type, street name, building number (which may include an apartment number), and postal code. It can also generate gender-associated Polish names, ages, and fake credit card numbers that pass the Luhn algorithm, allowing you to get a complete set of test user data with a single click.

How to Use: Step-by-Step Guide

Select Random, Male, or Female from the "Gender" dropdown menu—this determines the name database used for generation.
Enter a number range in the "Min Age" and "Max Age" input fields, such as 25 to 40. Leave them blank for no age limit.
Enter a specific Polish province in the "Province" input field (e.g., Małopolskie). Leave it blank to randomly select from the 16 provinces.
Enter a city name in the "City" input field to filter further, such as Kraków.
Select your preferred card network in "Credit Card Type"—Visa, Mastercard, Amex, or Discover. Leave it as random to let the generator decide.
Click the "Generate" button, and the right card will display the complete dummy data. Click the "Copy" button next to the address to extract the address string in one click.

Complete Practical Example: Generating a Female User Address in Kraków

Suppose we are preparing user test cases for a Polish e-commerce platform and want to generate an address for a female user aged 25–40, living in Kraków, Małopolskie province, who holds a Visa card. Here is how to do it:

Select Female from the "Gender" dropdown menu;
Enter 25 in the "Min Age" input field and 40 in the "Max Age" field;
Enter Małopolskie in the "Province" input field;
Enter Kraków in the "City" input field;
Select Visa for "Credit Card Type";
Click "Generate".

The generator will output a result similar to this: ul. Floriańska 12/4, 31-021 Kraków, Małopolskie—this is a properly formatted Polish address, starting with "ul." for the street, a slash separating the building number and apartment number, followed by a five-digit postal code, the city name in the middle, and the province at the end. You will also see a corresponding female name (e.g., a common Polish name combination starting with Agnieszka) and a dummy Visa card number that passes the Luhn check. Now you can click the "Copy" button next to the address to paste the entire address into your test spreadsheets, automation scripts, or frontend UI prototypes.

Typical Use Cases

Development and Test Data Population: Frontend engineers need to populate registration forms and address management pages with hundreds of Polish addresses to ensure field truncation, regex validation, and international characters (like ę, ś, ł) display correctly. Using our generator is fast and meets formatting expectations, saving you from manually copying from Wikipedia.

Data Anonymization for Demos: When presenting a product roadmap or data analysis visualization, you may need to plot points on a map to show "Polish customer distribution" without using real private addresses. The generated dummy addresses protect privacy while maintaining the visual realism of streets, provinces, cities, and postal codes.

Learning Polish Address Formats: International students or new e-commerce operations staff can repeatedly generate addresses to carefully observe "ul.", "al.", and the comma omission rules between postal codes and cities, quickly familiarizing themselves with Polish envelope writing conventions.

Common Misuses: Pitfalls to Avoid

Using for Actual Mailing: The addresses are random fake combinations. The postal codes do not correspond to any real streets, so packages will definitely be returned.
Using for Real-Name Registration: Using generated names and addresses to verify identity on websites, banks, or government systems will be flagged as false information, potentially leading to account bans or legal risks.
Paying with Fake Credit Card Numbers: The output card numbers only pass the Luhn check. They have no issuing bank, expiration date, or CVV. Using them for online payments constitutes fraud.
Contradictory Province and City Filtering: If you enter a province in the "Province" field but enter a city belonging to a different province in the "City" field, the generator may output unexpected results or empty values, as the tool does not cross-validate data consistency across levels.

Notes and Limitations

The addresses and affiliated information generated by this tool are strictly dummy data and are prohibited from being used for real mailing, legal document registration, or any scenario requiring authenticity verification.
Postal codes strictly follow the Polish XX-XXX format but are not active codes assigned in the actual Poczta Polska delivery system, making them unusable for mail sorting.
The name database is built on common Polish names, and the combined results do not represent any real individuals. Credit card numbers are mathematically synthesized and hold no financial validity.
The entire generation process is completed locally in your browser, with no inputs or outputs transmitted to our servers. However, it is still not recommended to generate and save test credit card numbers on public computers.
This tool relies on a generic address generation component. When both province and city filters are set but do not match, the returned result may be empty or unexpected—this is a current dataset constraint of the component, which we will continue to optimize.

Frequently Asked Questions

Can the generated addresses be printed on envelopes and mailed?
Absolutely not. The addresses are randomly synthesized. The street numbers and postal codes do not correspond to any real buildings, and the post office will return them.

Can I generate 100 addresses at once?
Currently, the interface generates one address per click. If you need bulk data, you can click multiple times or use the browser console to loop the generation logic.

Why doesn't the generated city match after I enter a province?
Because the generator is a generic address component and does not perform logical validation between provinces and cities. If you want an address in Kraków, it is recommended to only fill in the "City" and leave the "Province" blank, or vice versa.

Are the credit card numbers real?
No. They are merely 16-digit strings mathematically validated by the Luhn algorithm. They have no issuing bank, no expiration date, and no security code, making them completely unusable for transactions.

Can I use it to test UI multilingual typography?
Of course, this is what the tool excels at. The generated addresses contain special Polish characters (such as ę, ą, ś, ł), making them perfect for validating font fallbacks, line heights, and input field widths.

Now you can adjust the gender, age range, and city filters in the generator above to try out your first set of dummy Polish data.
