Quick Answer — How to Register for a Peppol ID in Singapore
A Peppol ID is your unique identifier on Singapore's InvoiceNow e-invoicing network. To register, you need to select an IMDA-accredited InvoiceNow-ready solution or Access Point Provider, which will assign you a Peppol ID linked to your UEN. Registration is typically completed within the software setup process at no additional cost, and you will be listed in the SG Peppol Directory.
What Is a Peppol ID and Why Do You Need One?
Peppol (Pan-European Public Procurement Online) is the international e-invoicing standard adopted by Singapore's Infocomm Media Development Authority (IMDA) for the InvoiceNow network. A Peppol ID is your business's unique identifier on this network — similar to an email address but specifically for sending and receiving structured e-invoices.
According to IRAS, your Peppol ID is linked to your Unique Entity Number (UEN). When you send an invoice via InvoiceNow, the network uses your Peppol ID and your customer's Peppol ID to route the structured invoice data directly between your accounting systems.

For the GST InvoiceNow requirement, having a valid Peppol ID is mandatory for new voluntary GST registrants from 1 April 2026. Without one, IRAS will not approve your GST registration application.
Understanding the InvoiceNow "5-Corner" Model
According to the InvoiceNow framework, the network operates on a "5-corner model" with the following participants:
- Sender — Your business issuing the invoice
- Access Point (Sender) — Your InvoiceNow-ready solution or provider
- Receiver Access Point — Your customer's provider
- Receiver — Your customer's accounting system
- IRAS (5th Corner) — Receives a real-time copy of invoice data for tax compliance
Your Peppol ID is what allows all five corners to recognize and route invoices correctly.
