Every UAE business needs one of these to send or receive an e-invoice on the Peppol network. Here's the exact format and the four steps to get yours.

Every UAE business needs one of these to send or receive an e-invoice on the Peppol network. Here's the exact format and the four steps to get yours.
If you've read the FTA's e-invoicing mandate documents, you've probably seen the term "Peppol Participant ID" or "Peppol Endpoint Identifier" without much explanation of what it actually looks like or how you get one. It's a small technical detail with a big practical consequence: without it, your business cannot be found on the Peppol network at all — no invoice can be routed to you or from you.
This guide covers exactly what the identifier is, why it matters, and the real steps to obtain it — no guesswork.
InvoiceUAE is built by Infotree Computers LLC, a Dubai-based technology firm that has been implementing QuickBooks, Sage 50, Sage 300, Zoho One and Zoho Books for UAE and GCC businesses for 14 years. Infotree is a Certified QuickBooks ProAdvisor, Authorized Zoho Partner, Authorized Sage Partner, and holds Odoo Gold Partner status at the Gold level through an affiliate partnership. The team operates from offices in Dubai (UAE), Saudi Arabia, and Bhubaneswar (India), and InvoiceUAE's ASP partner is TaxStar (FTA-approved).
A Peppol Participant ID is your business's unique routing address on the Peppol network — the international infrastructure the UAE uses to move e-invoices between trading partners and, simultaneously, to the Federal Tax Authority. Think of it the way you'd think of an IBAN for bank transfers: a fixed-format identifier that tells the network exactly where a document needs to go, without either party needing to set up a direct connection first.
In the UAE, the identifier follows a fixed structure:
0235:1234567890
0235 is the ISO 6523 scheme identifier that marks this as a UAE Tax Identification Number. The digits after the colon are your business's 10-digit TIN. Every invoice sent under the UAE's PINT-AE format carries this identifier for both the supplier and the buyer, wrapped inside the document's Sender/Receiver header so the Peppol network — and every Accredited Service Provider (ASP) along the way — knows exactly who is issuing and receiving it.
Under the FTA's phased e-invoicing rollout, structured B2B and B2G invoices must travel through the 5-corner Peppol model rather than as a PDF or email attachment — see our 5-corner model explained for the full mechanics of how a document actually moves from your ERP to the FTA. The Peppol Participant ID is the addressing layer that model depends on: without a published ID, your ASP has nowhere valid to route an outgoing invoice, and no other business can address one to you.
The compliance deadlines that make this urgent, per the current Ministry of Finance timeline (see our full mandate guide for the complete breakdown):
| Business Size | ASP Appointment Deadline | Mandatory Go-Live Date |
|---|---|---|
| Revenue ≥ AED 50 million | October 30, 2026 | January 1, 2027 |
| Revenue < AED 50 million | March 31, 2027 | July 1, 2027 |
There's a second, less obvious reason to get this sorted early even if your own go-live date is further out: from January 2027 onward, larger buyers who have already gone live on Peppol-native purchasing systems will start asking suppliers for their Peppol Participant ID as part of standard vendor onboarding — the same way they'd ask for a TRN or bank details today. Not having one ready can hold up a new vendor relationship even before your own mandatory deadline arrives.
This is the single most common point of confusion, and it's worth being precise about: your TRN (Tax Registration Number) is the full 15-digit number the FTA assigns when you register for VAT. Your TIN (Tax Identification Number), for Peppol addressing purposes, is only the first 10 digits of that same TRN.
So if your TRN is 100041287300003, your Peppol Participant ID uses only 1000412873 — formatted as 0235:1000412873. Using the full 15-digit TRN where the network expects a 10-digit TIN causes an invalid identifier and routing failures. This isn't a rare edge case; it's a mechanical detail that trips up manual PINT-AE XML construction constantly, which is exactly why letting your ASP or e-invoicing platform generate the identifier for you — rather than typing it in by hand — removes the risk entirely.
There's no separate application form or portal specifically for the Peppol ID itself. It's generated as a byproduct of the same process you already need to go through to comply with the mandate:
In practice, steps 3 and 4 happen together, in the background, the moment your entity is created with a valid TRN on file. There's nothing to copy, paste, or format by hand.
InvoiceUAE connects to TaxStar, our FTA-accredited ASP partner, via a standard OAuth entity-registration flow. Once your company profile has a valid 15-digit TRN and address on file in Settings → Company, connecting TaxStar under Settings → ASP / Peppol automatically registers your business as an entity and derives your 0235:TIN Peppol Participant ID from that TRN — you never construct or enter the identifier yourself.
If you've already registered a company entity directly on TaxStar's own developer portal (for example, while testing a different accounting connection), InvoiceUAE also supports linking to that existing entity by ID instead of creating a duplicate one, so your invoice history stays in one place.
Not sure if your ASP connection is set up correctly? InvoiceUAE shows your connected entity status directly in Settings, so you can confirm your Peppol ID is live before you rely on it.
Start Free Trial →The identifier itself carries no government fee — the FTA and Ministry of Finance do not charge for issuing a Peppol Participant ID. Whatever cost is involved comes from your ASP's own service pricing for onboarding, system integration, and ongoing invoice submission volume, which varies by provider. A platform that already bundles ASP connectivity, like InvoiceUAE, includes this entity and ID provisioning as part of the standard setup rather than as a separate line item.
If your mandatory go-live date arrives without a working Peppol Participant ID, you are not able to legally issue or receive structured e-invoices from that date. That triggers the administrative penalties under Cabinet Decision No. 106 of 2025 — a continuous monthly penalty for not having an ASP appointed or the system activated, plus separate per-invoice penalties for late transmission once you do start submitting. See our complete penalties guide for the full fine breakdown and how to avoid triggering them.

Every UAE Peppol Participant ID follows the pattern 0235:<TIN> — the prefix tells every other party on the network which numbering scheme to use when reading the identifier that follows.
Your TRN is the full 15-digit number the FTA assigns when you register for VAT. Your Peppol Participant ID uses only the first 10 digits of that TRN (the TIN), formatted as 0235:<TIN>. They're related but not interchangeable — putting the full 15-digit TRN into a field that expects the 10-digit TIN causes routing failures.
No. There's no separate self-service registration for the identifier itself — an FTA-accredited ASP generates it from your TRN and publishes it to the Peppol Directory as part of connecting your accounting system, which is why choosing an ASP is the real first step.
The government charges no fee for the identifier itself. Any cost comes from your ASP's own service fees for onboarding, system connection, and ongoing invoice submission, which vary by provider.
You won't be able to legally issue or receive structured e-invoices from that date, which triggers the non-compliance penalties under Cabinet Decision No. 106 of 2025 — a monthly penalty for not having the system activated, on top of per-invoice penalties for anything submitted late.
