Our Experience?

Many satisfied customers

Banks, insurance companies, telephone operators, state secure and rescue services and others.


Our specialists have participated in the development from the very beginning. We have extensive knowledge of the register.

We developed the UIR-ADR Register

We have many years of experience in territorial identification and addresses. We have developed UIR-ADR (Territorial Identification Register of Addresses) which had been used by the Ministry of Labour and Social Affairs before the new register (RUIAN) was developed. UIR-ADR was one of the key systems RUIAN was based on.

What are our customers interested in?

Is the register always up-to-date?

Yes. Updates are automatically downloaded every day. You can choose the time of the download – e.g. at night, so that in the morning the data is up-to-date.

Do you offer customer support if needed?

Yes. Over the phone, in writing or in person. We guarantee to make changes in the register quickly.

We use the old register (UIR-ADR) which is not supported anymore. What should we do?

We can provide you with an extension pack which has the same interface as the UIR-ADR. You can easily migrate to the new register with minimal impact on your application. The codes of the individual elements stay the same.

Can I use OKadresy for my own project?

Yes, you can. With our solution, you can easily enter and search addresses, incorporate RUIAN into maps, connect it with flood zones detection application and other individual adjustments. The register support facilitates addresses entering. The user can enter the address only partially or inaccurately and the program offers generated suggestions. You avoid pasting a non-existent address or duplications. Your data will be accurate and your shipments will always find their recipients.

Do I need to be online when working with the database?

No. Once you have up-to-date data, you can work with the database completely offline. This will greatly increase speed and efficiency.

What do I need for working with RUIAN?

You need only a PC with JAVA installations. We support Oracle databases, Microsoft SQL server, MySQL (or others which can be discussed individually). Internet access is required to download updates.

What kind of information does OKadresy contain?

Addresses, urban areas, parts of municipalities, streets... The basic data range is identical to the old UIR-ADR system. In addition, we offer other extension packs such as definition points, element boundaries, plots and conversion to GPS coordinates. You can instantly view an address on the map in your preferred app.

Do you help me implement OKadresy into my project?

Yes. We will clean your existing databases from multiple entries and unify your addresses with the RUIAN register. We will provide links to third-party applications.
