 Note to utf:
The ARES database contains the words with the Czech letters:
á Á č Č ď Ď ě Ě í Í ň Ň ó Ó ř Ř š Š Ť ť ú Ú ů Ů ý Ý ž Ž
as well as the words with the following diacritical marks:
ä Ä ă Ă ą Ą â Â ç Ç ć Ć Ę ę ë Ë î Î ĺ Ĺ ł Ł ľ Ľ ń Ń ô Ô ö Ö ő Ő ŕ Ŕ ś Ś ş Ş ţ Ţ ű Ű ü Ü ź Ź ż Ż

Any other characters with diacritical marks as well as the characters of national alphabets which are out of range A-Z (ASCII 65-90) or a-z (ASCII 97-122) are regarded as invalid in spite of the fact that they are admissible characters in UTF-8. For example, it is not allowed to search by the € symbol (Eurocurrency), use wildcard character * instead of that.

Since ARES as such cannot correct any error data, the ARES database may contain the words with typing errors.

Examples of the correct words in the ARES database: PĂCĂLĂU, TYBETAŃSKA, ĆMIEL, Jäger, Rău, spółka odpowiedzialnością, Bîrcâ, Françoise, Jedność, Pękała, CITROËN, Oĺga, Cieńciała, Kraľ, Truściński, Hlôska, Götzel, Vŕzgna, Şimşir, Műller, Müller, Gwóźdź, Elżbieta.

Examples of the typing errors in the ARES database: BERANOVĂ, BAHŃÁCI, BŔÍZOVÁ, JIĆÍN, Hlaváçková, TOMAŚ KUĆERA, PROTIPOŹÁRNÍ.


The Standard service displays basic information on the entity contained in the ARES core. The data comes from one of the sources defined as a priority source for this entity. The name of the source where the data comes from can be found in the element Typ_registru. The following data is regarded as basic: Reg.No., Business name, Legal form, Date of establishment, Address.

The element Datum_vzniku contains the date the meaning of which may differ in dependence on a type of the register. In the sources RES, RCRS the said element contains the entity's Date of establishment or Date of registration, in CR it means Record date, in TR it means the date of registration of the first trade. The same it is with the element Datum_zaniku when in CR it means the date of entity's deletion from CR.

The element Adresa_ARES contains the address of the entity, which is standardized on the basis of data from RUIAN (i.e. improved names of the streets, completed numbers of houses, postcodes improved on the basis of RUIAN data; if the address of the entity is not assign unambiguously to the address in RUIAN, it would not be standardized). The element Adresa_UIR contains the data from the RUIAN register.

The element Adr_puv (it is written only if the parameter adr_puv=true is used) contains information of address of entity as it is written in the data source (before the process of standardization is used).

Note: The data sources give the address in different ways. Some give it in the text, some in address codes only, some give it structured and some unstructured. The output element Adr_puv contains the address, if possible, structured, text data remains unchanged and any address codes are replaced with texts according to the dials of appropriate source. The address of the element Adr_puv enters into the process of address standardization during data processing in ARES. The address standardization creates the standardized address contained in the element Adresa_ARES.
