ISO customers often inquire about the inclusion of RFC (Mexican tax ID) details in invoices or purchase documents. Below is a comprehensive explanation of ISO's policies regarding this matter.

ISO adheres to specific invoicing practices that comply with international standards. These practices include policies on the inclusion of tax identification numbers, such as the RFC, and the treatment of value-added tax (VAT).

RFC numbers are generally not included in ISO's final fiscal invoices. This policy applies across all transactions, including those conducted through the DGN webstore. ISO pricing is exclusive of Mexican VAT (IVA), and customers are responsible for applying VAT in Mexico. As a result, RFC details are not included in final invoices and cannot be added or reissued with RFC information.

While RFC numbers are not included in final invoices, they can be added to purchase documents for administrative or reference purposes. This exception is available upon request and is intended solely for internal or administrative use. It does not affect the fiscal nature of the document or its compliance with tax regulations.

For orders placed through the DGN webstore, RFC numbers cannot be added to invoices under any circumstances. These transactions are treated as transfers of tangible or intangible goods, and the invoices are issued without RFC details. Customers should note that this policy is consistent with ISO's general approach to invoicing and VAT exclusions.

ISO pricing does not include Mexican VAT (IVA). Customers are responsible for calculating and applying VAT in accordance with local tax laws. This policy ensures compliance with international invoicing standards and simplifies the pricing structure for global customers.

By understanding these policies, customers can better navigate ISO's invoicing processes and ensure compliance with their own administrative and tax requirements. For further assistance, please contact ISO customer support.
