The details the FTA returns at step 2 depend on how your business is registered. All three cases below onboard successfully — but two of them show something that looks wrong at first glance and isn’t.

VAT-registered business

The straightforward case. The FTA returns your legal names, your VAT TRN, and the effective date of registration. Nothing needs explaining.

Corporate Tax only — no VAT TRN

If you’re registered for Corporate Tax but not for VAT, the FTA returns your legal type and legal names, and leaves VAT TRN and Effective Date of Registration empty.
Review and Confirm for a Corporate Tax-only business, with the VAT TRN and effective date fields empty
This is correct — don’t be alarmed by the blank fields. You have no VAT registration, so there is no TRN to show. The form accepts it, and onboarding completes normally. Your e-invoicing identity does not depend on having a TRN.

Member of a VAT group — the TRN won’t be yours

If you’re a member of a VAT group, the FTA returns the group’s TRN, not the one on your own registration. The two are different numbers, and the effective date is the group’s too.

The TRN shown here can differ from the one on your own EmaraTax registration overview. We display exactly what the FTA’s verification returns — the field is non-editable and we do not alter it.

Why your TIN is what matters

Whichever of the three you are, your identity on the e-invoicing network is minted from your TIN:
Never from the TRN. That is what makes the two cases above harmless — a missing TRN or a group TRN changes nothing about how invoices are addressed to you. Your counterparties route to your TIN-based identifier, and so does everyone’s lookup of your business on the network.
If you’re checking your own registration on the network and it doesn’t resolve, look it up as 0235: followed by your TIN. Looking it up by TRN will not find you — that identifier was never created.
