# Switzerland

> What Coverbase asks a supplier in Switzerland 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 Switzerland 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      | Optional    | 3 to 5 characters, digits only             |                                                                   |
| Branch code    | Optional    | 3 to 9 characters, digits only             |                                                                   |
| Account number | Required    | up to 17 characters, digits only           |                                                                   |
| 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 required for Switzerland. It is 21 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                     |
| ------------ | ----------- | -------------------------------------------------- | ------------------------- |
| UID          | Required    | 12 characters, letters and digits, UID check digit | CHE followed by 9 digits. |

After a registration is saved, Coverbase checks it against the Swiss UID register 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 CH validations; BFS UID 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.
