User guides / Supplier countries A supplier whose bank account is held in Singapore sees the fields below. The country is chosen on the form, and changing it changes the fields, so a supplier is never asked for a detail their country does not use.

​
Bank details

​
IBAN

An IBAN is optional for Singapore. It is up to 34 characters and is checked against the ISO 7064 MOD-97 algorithm, which catches a mistyped or transposed digit before the details reach your finance system.

​
Tax and company registrations

After a registration is saved, Coverbase checks it against ACRA in Singapore in the background. That check never blocks the supplier: it annotates the record once it completes, and a reviewer can retry it.

​
Where these rules come from

Oracle Fusion Cash Management 26c SG validations. UEN check-digit algorithms are not published by ACRA, so structure only (no checksum). The rules on this page are confirmed against a primary source, so they are enforced strictly. Configuration version 2026.09.1. Your organization can override any of these rules for its own suppliers.

Every country Coverbase validates, side by side.
