# FTA Linking Overview

> How your business is linked to the Federal Tax Authority for e-invoicing, and the three actions you can take.

Before you can send or receive e-invoices, your business has to be **linked** with
the UAE Federal Tax Authority (FTA) through an Accredited Service Provider (ASP).
Fatorly is an accredited service provider, and this section covers every part of
that relationship — setting it up, refreshing it, and ending it.

<Note>
  **Linking always starts in EmaraTax, never here.** The FTA portal hands you over to
  us with a secure, single-use request. Opening `/onboarding` directly, without that
  request, shows a "missing request" message — that is expected, not a fault.
</Note>

## The three actions

Everything you can do with your FTA link is one of these three. EmaraTax offers
whichever ones apply to your current state.

<CardGroup cols={3}>
  <Card title="Onboarding" href="/en/fta-linking/onboarding">
    Create the link. Available when your TIN is not currently linked to any
    provider.
  </Card>

  <Card title="Reverification" href="/en/fta-linking/reverification">
    Refresh your registration details with us, without changing the link itself.
  </Card>

  <Card title="Offboarding" href="/en/fta-linking/offboarding">
    Remove the link — because you're closing, or moving to another provider.
  </Card>
</CardGroup>

## What you need to hand

| What                                         | Why                                                                                                                                                 |
| -------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- |
| Access to **EmaraTax**                       | Every action begins there.                                                                                                                          |
| Your **TIN** (Tax Identifier Number)         | 10 digits, starting with `1`. EmaraTax shows it on the e-invoicing screen as *"Your TIN for e-invoicing Onboarding"*.                               |
| The **e-mail address the FTA holds for you** | The FTA checks this against its own records. If it doesn't match, verification is refused — see [Troubleshooting](/en/fta-linking/troubleshooting). |

Your registered mobile number is optional.

<Warning>
  **Each linking session lasts 15 minutes.** A countdown runs in the bottom-left
  corner of the wizard. If it reaches zero you don't lose anything permanently — you
  just go back to EmaraTax and start a fresh request.
</Warning>

## Your TIN is your network identity

Once you're linked, your identity on the Peppol e-invoicing network is built from
your **TIN** — as `0235:<your TIN>`. It is never built from your TRN, even when you
have one, and even when the TRN the FTA returns belongs to a VAT group rather than
to you. See [Kinds of taxpayer](/en/fta-linking/taxpayer-types) for why that
distinction matters.

## About the screenshots in this section

The screens below are real, but every identifying value in them has been replaced
with a placeholder: TINs appear as `1XXXXXXXXX`, TRNs as `1XXXXXXXXXXXXXX`,
e-mail addresses as `you@company.com`, and company names as *Your Company*. Your
own screens will show your real details in those places.
