Application Programming Interface (API) Used to Validate a QST Registration Number
|Purpose of the service||
To validate a business's QST registration number using an application programming interface (API).
The service provides the following information:
|Users||Businesses, individuals in business, corporations and suppliers outside Québec|
|Required information||The registration number (ten digits followed by the letters TQ and four more digits).|
If the QST registration number you wish to validate has only nine digits, does not include the letters TQ and is identical to the GST/HST registration number, the business is a selected listed financial institution. Revenu Québec has mandated the Canada Revenue Agency to administer the QST collected by such businesses.
To validate such a number, use the GST/HST Registry, available on the Governement of Canada website.
|Important||You can also use the Validate a QST Registration Number online service to validate a QST registration number.|
To use this API, you must:
- have abilities in application programming;
- refer to the User Guide: Application Programming Interface Used to Validate a QST Registration Number (SW-340-V);
- connect your tools to the API.
