UAE Supplier Registration: Every Detail Vendor Portals Ask For

The Relay Team · 4 November 2026 · 4 min read

Every new client in the UAE seems to have its own vendor portal. Government entities, semi-government groups and big private companies all want you registered as a supplier before they raise a purchase order, and every portal asks for the same company details in a slightly different form.

Here's what they usually ask for, based on published supplier guides from UAE entities, and a faster way to fill them in.

The details almost every portal asks for

Company basics

  • Company name exactly as it appears on your trade licence (some portals also want the Arabic name)
  • Legal entity type, place and year of incorporation
  • Registered address, P.O. Box, official phone and email
  • A point of contact: name, designation, mobile number and email

Licence and tax

  • Trade licence (or commercial licence) number, issue date and expiry date
  • Licence activities, which should match the product and service categories you pick
  • VAT Tax Registration Number (TRN), if you're registered

Bank details

  • Bank name and branch
  • Account name, account number and currency
  • IBAN (a UAE IBAN is 23 characters, and some portals check it against your bank letter)
  • SWIFT code, often asked for alongside the IBAN

Authorised signatory

  • Name of the owner, partners or authorised signatory
  • Their passport and Emirates ID details, plus copies

The documents they ask you to upload

Most portals also want scans or PDFs of:

  • Trade licence or certificate of incorporation
  • VAT (TRN) certificate, if applicable
  • A bank letter showing your IBAN
  • Power of attorney or authorisation letter for the signatory
  • Passport and Emirates ID copies of the authorised signatory
  • Sometimes a company profile, ICV certificate, ISO or HSE certificates and audited financials

Why it takes so long

None of this is hard. It's just the same 20 or so values, typed again on every portal, often from a PDF on one screen into a form on another. One wrong digit in an IBAN or TRN can hold up your registration, and your first payment with it.

Save them once in Relay, then fill each portal in minutes

Relay is a private keyboard that keeps the details people keep asking you for in an encrypted vault on your device. Save your company details once, then insert them into each portal field straight from your keyboard.

  1. Save each value once. Add your trade licence number, TRN, IBAN, SWIFT code, company address and contact details as separate items, so each one goes into its own field. Scan the signatory's passport or Emirates ID and Relay reads the details for you; check them and save.
  2. On your phone, tap the form field, switch to the Relay keyboard and tap the detail you need. It types itself into the field. On iPhone, sensitive items ask for Face ID or Touch ID first.
  3. On your computer, most vendor portals are filled in on a laptop. On Windows, click into the field, press Ctrl + Shift + V, search your vault and press Enter. On Mac, press ⇧⌘V, pick the detail, then paste it with ⌘V.

Your vault is encrypted on your device and we can't read it. No account is required.

A quick checklist before you submit

  • Copy the company name exactly as the trade licence prints it, including "LLC" or "FZ-LLC".
  • Check the trade licence expiry date. Many portals reject an expired or soon-to-expire licence.
  • Make sure the IBAN matches the bank letter you upload, character for character.
  • Pick service categories that match your licence activities, or you may not be invited to the right tenders.
  • Keep the signatory's passport and Emirates ID copies current, and update the portal when they renew.

FAQ

What documents do I need for supplier registration in the UAE?
Most portals ask for a valid trade licence, a VAT (TRN) certificate if you're registered, a bank letter showing your IBAN, an authorisation letter or power of attorney, and passport and Emirates ID copies of the authorised signatory. Some also ask for a company profile, ICV, ISO or HSE certificates and financial statements.

How long is a UAE IBAN?
A UAE IBAN is 23 characters, starting with AE. Saving it once in Relay means you insert the exact same value every time instead of retyping it.

Can I use Relay on my computer for vendor portals?
Yes. Relay has apps for Windows and Mac. On Windows, press Ctrl + Shift + V in a field to search your vault and insert a detail; on Mac, press ⇧⌘V, pick the detail and paste with ⌘V.

Do I need an account to use Relay?
No. Your vault is encrypted on your device and no account is required.
