# Singapore

> What Coverbase asks a supplier in Singapore for, and which of those rules block a submission.

[User guides](/user-guides/overview) / [Supplier countries](/user-guides/supplier-countries/overview)

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

| Field          | Requirement | Format                                     | Notes                                                             |
| -------------- | ----------- | ------------------------------------------ | ----------------------------------------------------------------- |
| Bank name      | Optional    | up to 60 characters                        |                                                                   |
| Bank code      | Required    | 4 characters, digits only                  | 4 digits.                                                         |
| Branch code    | Required    | 3 characters, digits only                  | 3 digits.                                                         |
| Account number | Required    | up to 14 characters, letters and digits    |                                                                   |
| Check digit    | Optional    | no length limit, digits only               |                                                                   |
| SWIFT/BIC      | Optional    | 8 to 11 characters, letters and digits     | 8 or 11 characters, e.g. BOFAUS3N. Needed for a payment by wire.  |
| Account type   | Optional    | no length limit, one of: checking, savings | Checking unless the bank issued the account as a savings account. |

### 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

| Registration | Requirement | Format                                 | Notes                                |
| ------------ | ----------- | -------------------------------------- | ------------------------------------ |
| UEN          | Required    | 9 to 10 characters, letters and digits | 9 or 10 characters, e.g. 200312345A. |

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.
