  "account": "In many European countries, a company's VAT number is not a separate secret but rather the company's own identifier in a fixed format. However, there is no rule for the United Kingdom, Ireland, Slovakia, or Estonia. Here are the rules for obtaining a company's EU VAT number from its company number in 10 countries.\n\nFor Spain, the VAT number is the company's NIF, which consists of letters A–W followed by 7 digits. For France, the VAT number is the SIREN, which is a 9-digit number prefixed by the two-digit key calculated as (12 + 3 × (SIREN mod 97)) mod 97. Poland's VAT number, NIP, is a 10-digit number prefixed by PL. Norway's organisasjonsnummer is a 9-digit number prefixed by NO and suffixed by MVA.

Switzerland's UID is a 9-digit number prefixed by CHE and suffixed by MWST.\n\nIt is essential to note that there is no rule to determine whether a derived number is valid or if the company is actually registered for VAT.
