A VAT registration number (DIČ) is a unique and unambiguous identification of each tax entity, a legal or natural person who is a taxpayer (taxpayer). The tax identification number is assigned only after the entity, natural or legal person, obtains its IČO - its unique identification number. Note that the list [CZ-ICO](/list/CZ-ICO) might therefore provide a better set of identifiers for legal entities.
