Invoice format and locale facts for Tanzania

Why these defaults?

The country code comes from ISO 3166. Unicode CLDR supplies presentation-oriented locale, currency, paper, date, language, calendar, numbering, and direction metadata. Defaults reduce setup time; they do not decide what a valid document must contain.

Document vocabulary and checks

Official OAG and TRA sources for fiscal receipt/invoice data, TIN/VRN vocabulary, five-year tax and EFD-record retention, and the EFD fiscalisation boundary are reviewed. Formnivo does not validate identifiers, determine VAT liability, approve or emulate a device, fiscalise, report, or verify a transaction.
