Registering on the Central Digital Platform (CDP) for your Unique Supplier ID / PPON: Step by Step Supplier Guide

The Procurement Act 2023 came into force on 24 February 2025 which has led to a number of changes to how goods and services are procured in the public sector.

A key part of the new system is the Central Digital Platform (CDP), which every supplier will need to use.

In order to tender or provide quotations to the public sector suppliers must:

Register on the CDP / Find a Tender Service (FTS)
Get your unique supplier ID / Public Procurement Organisation Number (PPON)
Add this ID to your Sell2Wales profile (if relevant)

This will allow you to continue tendering or quoting for public contracts.

Suppliers only need to register once to create their supplier ID/PPON.

What you need to do Step‑by‑Step

Step 1: Prepare your core supplier information

Why this step matters

Preparing this information in advance will make your registration on the Central Digital Platform (CDP) much quicker and smoother. Once your details are entered, they can be stored and reused for future tenders, so you won't need to provide the same information again.

You will need:

Basic business information

Organisation name and address
Companies House number or Charity Commission number
VAT number (if applicable)
Relevant qualifications or trade association memberships
Confirmation of whether you are an SME, VCSE, or public service mutual

The following information is also required to fully complete your CDP account, but is not required to initially create an account and receive your unique identifier:

Financial information

Most recent annual accounts

Connected persons

Names, addresses, and details of persons with significant control or influence

Exclusions information

Details of any mandatory or discretionary exclusion grounds
(as set out in Schedules 6 and 7 of the Procurement Act)

Step 2: Register on the Central Digital Platform (CDP) / Find a Tender Service (FTS)

Why this step matters:

You must complete this step to receive your unique supplier ID. This ID is essential, as you will not be able to tender under the new Procurement Act regulations without it.

How to register

Go to Find a Tender: https://www.find-tender.service.gov.uk/
Create an account (or re‑register if you already have one).
Enter your organisation's details following the on‑screen steps.
Once complete, the system will generate your unique supplier ID/PPON, in this format:
PPON ABCD‑1111‑EFGH
Record and keep this information and provide upon request.

Go to Supplier Control Panel
Select Company profile under the heading My Profile.
Scroll to the Central Digital Platform (CDP) section
Enter your unique supplier ID in the Unique Identifier (UI) box
Select Save changes
