Searching the Central Register of Animals and Objects by Microchip Code

The Central Register of Animals and Objects of the Czech Republic is a publicly accessible database (register) where you can:

search for a dog (dogs)
search for a cat (cats)
search for a ferret (ferrets)
search for a bicycle (bicycles)
search for objects

For each record, you can also find the owner of the animal or object marked with a microchip. In the search form field labeled Microchip Code, enter the microchip code of the owner you wish to search for. In the next field, copy the text from the captcha image and click the Search button. The search will be performed and the result will be displayed.

Example of microchip search

Enter the microchip code you are searching for, copy the text from the captcha image, and click the "Search" button. The image below shows an example when searching for a microchip with code 0000622F24. If the captcha text is difficult to read, click the "Another image" button to generate a new captcha.

Microchip codes - ISO, HEXA

In short, the microchip code can be expressed in hexadecimal format (HEXA) or ISO format. The hexadecimal format is not a direct conversion of the ISO representation into the hexadecimal system. Readers used for determining the microchip code usually allow switching between reading the code in ISO format and reading the code in HEXA format. The following images show the result of reading the same microchip with one reader, where the reading mode was switched between the first and second reading.

Which result is correct? Both results are correct and represent the code of a single microchip. You do not need to deal with converting the codes yourself – our server will perform this work automatically for you.

When you enter a microchip code for search, it will be automatically converted into both ISO and HEXA formats, regardless of the format in which the microchip code was recorded in the database.

Search Results

If the searched microchip code is not found in the database, the server will display a message stating that the microchip with the searched code is not included in the registry. Example message:

123456789012345 - microchip is not included in the Central Registry

If the microchip is found in the Central Registry (microchip with code 0000622F24 is included as a test record, you can try searching for this microchip yourself), the server will return information about the microchip – typically in this form:

The search results may not always contain all the information. In the displayed example, there is no information about the recipient and the local register — this means that such information is not listed in the Central Register. The following is an explanation of all the terms that may appear in the search results.

Microchip code	In the result, the entered microchip code is repeated for clarity. If the microchip code can be expressed in both hexadecimal and ISO format, both representations are shown in the result. This is to prevent confusion if the microchip code is found in a different format than the one used for the search. The difference between ISO and HEXA formats is explained earlier on this page.
What is marked	Information about what is marked with the microchip — in the example, this is a test record where the microchip is assigned to a plush teddy bear.
Distributor	The company (or person) that distributed the microchip within the territory of the Czech Republic.
Recipient	The company (or person) that took delivery of the microchip from the distributor.
Local register	Contact details for the local microchip registry, typically the municipal office or a company authorized to maintain the local register.
Collection point	The workplace from which the microchip was entered into the Central Register of Animals and Objects of the Czech Republic. For animals, this usually means a veterinary practice; for bicycles, this may be a service point that installed the microchip, and similar. Under no circumstances does this indicate the location where the lost dog or object is currently located.
Owner	Contact details of the owner of the animal or object marked with the microchip, including the date the record was registered.

Registration in the Central Register of Animals and Objects is a paid service

The registration fee is a one-time fee and covers the costs associated with registration and the publication of the data in the first year when the record is stored in the database. In the following years, there are no additional registration or maintenance fees for the registered record. As part of the registration, it is possible to update the data free of charge (change of address, telephone number, etc.). However, a change of the owner's name or the microchip code is always considered a new registration.

Change of Owner

When changing the owner, the new registration does not cancel the original registration, but data from both registrations are available. The Central Register of Animals and Objects of the Czech Republic handles the data in the manner shown in the following example

The first owner registers information about the dog (cat, bicycle, etc.) in the Central Register. After paying the registration fee, the information registered by the first owner is accessible via the search form. The record also contains the registration date.
The first owner gives (sells) the dog (cat, bicycle, etc.) to the second owner.
The second owner registers the information about the dog (cat, bicycle, etc.) in the Central Register. After paying the registration fee, both the information registered by the second owner and that registered by the first owner are accessible via the search form.
If the first owner cancels the registration, only the information registered by the second owner will remain accessible.
