This page provides reference information for check issuance and cancellation, including supported values and limits.

## Currency codes

Currency codes identify the currency of a payment.

The following table includes each country’s supported currency codes:

 
**Currency codes**

| Country | Currency code | 
| --- | --- | 
| Canada | - CAD - USD | 
| United States | - USD | 

## Validation logic

If a check issuance has already been recorded, the API will return a message indicating that the request cannot be processed. When performing a cancellation, the system will verify that there is a corresponding issuance on file before proceeding with the cancellation.

## Value-amount limits

A value-amount limit identifies:  

 
**Value-amount limts**

| Country | Value-amount minimum | Value-amount maximum | 
| --- | --- | --- | 
| - Canada - United States | $0.01 | $99,999,999.99 |
