Terms of use

BazaKodow.pl (the “Service”) is operated by Jakub Piotrowski, contact: kontakt@jpconcept.pl.

These terms govern use of the website, including the postal code search, maps and AI assistant.

The data displayed in the Service is for information purposes only and is not an official directory issued by Poczta Polska. Postal codes and address boundaries change. Before posting an item, we recommend confirming the code on your postal operator’s website.

Database as of: 12 November 2026.

The Service is free to use and does not require registration.

The following are prohibited:

• bulk downloading and copying of the database (scraping) to build competing services;
• overloading the server with automated requests in a way that disrupts the website;
• bypassing AI assistant limits or other security measures;
• misrepresenting authorship of content or publishing unlawful content.

The AI assistant responds to address descriptions, but always retrieves postal codes from the Service’s database. Requests are subject to limits per network address and per day. Identical descriptions are answered from the cache.

The website’s design, logo, layout and original content belong to the Service operator. Address data comes from public registers (including TERYT/GUS and GUGiK’s State Register of Boundaries and Names of Geodetic Obstacles); maps are provided by OpenStreetMap under the ODbL licence.

You may link to pages within the Service and quote individual pieces of information with attribution.

We make every effort to ensure the data is accurate, but cannot guarantee that it matches the official PNA register in full at all times. The Service accepts no liability for the consequences of decisions made on the basis of the information displayed, including undelivered mail.

We reserve the right to temporarily interrupt the website’s operation for maintenance or data updates.

We may update these terms. The latest version is always available at this address.
