Customer Identification Types

The identification_type attribute indicates the legal identity scheme used to identify the buyer in the TRA EFDMS:

Code	Identification Scheme	Description and Format	Scope
`TAX_IDENTIFICATION_NUMBER`	Taxpayer Identification Number (TIN)	9-digit unique numeric identifier issued by TRA (e.g. `123456789`).	Required for B2B transactions where the buyer claims input VAT.
`NATIONAL_IDENTIFICATION_AUTHORITY`	NIDA National ID	20-digit national identity number issued by NIDA for Tanzanian citizens and resident individuals.	B2C transactions with national identification.
`PASSPORT`	Passport Number	International passport number for foreign natural persons and non-residents.	B2C transactions for international visitors/tourists.
`VOTERS_NUMBER`	Voter ID Card Number	Official voter registration number issued by the National Electoral Commission (NEC).	B2C individual identification.
`DRIVING_LICENCE`	Driver's License Number	Valid Tanzanian driver's license number.	B2C individual identification.
`NO_IDENTIFICATION`	No Identification (NIL)	Used when no customer identifier is collected (e.g. walk-in retail sales).	B2C retail transactions.

VAT Registration Number (VRN)

The vat_registration_number (VRN) is assigned by TRA to businesses registered for Value Added Tax. It typically follows the format 40-XXXXXX-X or 50-XXXXXX-X.

For B2B customers who are VAT-registered, include both the identification_number (TIN) and vat_registration_number (VRN) so both values appear on the fiscal invoice.
