TRN (Tax Registration Number) is the identification number given to every person registered under UAE VAT. It is mandatory that only persons having a valid TRN should charge VAT on supplies. In such a scenario, it is helpful for registered businesses to ensure that they receive supplies from a registered person, so that they can recover the input tax on the supply fearlessly.
For unregistered persons and consumers also, it is essential to ensure that only a genuine registered person charges VAT on supplies to them. To assist this, the FTA has given the provision to verify whether the TRN mentioned on an invoice or quoted by a supplier is valid. Any person can use this tool to ensure that the TRN quoted by their supplier is genuine.
Why is it necessary to verify TRN in the UAE?
Verifying a Tax Registration Number (TRN) in the UAE is a critical step for businesses to ensure VAT compliance, accuracy in transactions, and protection against fraud. It helps confirm that the supplier or customer is legitimately registered with the Federal Tax Authority (FTA).
