What is the Singapore Peppol Directory and how is a Peppol ID obtained?
The SG Peppol Directory is Singapore's national register of entities that are addressable on the InvoiceNow network. Businesses register using their Singapore Unique Entity Number (UEN) as the basis for their Peppol ID, enabling automated invoice routing between suppliers and buyers. GST-registered businesses subject to the IRAS GST InvoiceNow Requirement must register on the SG Peppol Directory to receive InvoiceNow-compliant invoices.
How is a UEN used to create a Peppol ID?
Singapore Peppol IDs are constructed by combining the Singapore country code scheme identifier with the business's nine-character Unique Entity Number (UEN), which is the national business registration number issued by ACRA (Accounting and Corporate Regulatory Authority). When a supplier issues an InvoiceNow invoice, their Access Point queries the SG Peppol Directory using the buyer's Peppol ID to determine the correct routing path to the buyer's Access Point.
Who must register on the SG Peppol Directory?
GST-registered businesses subject to the IRAS GST InvoiceNow Requirement must register their Peppol ID on the SG Peppol Directory to be reachable for InvoiceNow invoice delivery. Without a Peppol ID registration, automated electronic invoice routing to that buyer is not possible. IRAS encourages all GST-registered businesses, including those not yet under the mandatory phases, to register voluntarily.
Frequently Asked Questions
- Is the SG Peppol Directory the same as the global Peppol directory?
- The SG Peppol Directory is Singapore's national participant registry, federated into the global OpenPeppol directory infrastructure. Peppol IDs registered in Singapore are discoverable by Peppol Access Points in other jurisdictions. However, cross-border invoice routing between Singapore and other Peppol countries requires that both parties' Access Points are members of the international OpenPeppol network.
- How do I register on the SG Peppol Directory?
- Registration is typically completed through an IMDA-accredited Access Point or InvoiceNow-Ready software provider. The provider creates the Peppol ID entry in the SG Peppol Directory linked to the business's UEN. There is no direct self-registration portal for businesses—registration must be facilitated through an accredited network participant.
