Businesses have no legal obligation to inform Revenu Québec of their firm names. Therefore, Revenu Québec does not keep a record of all the firm names used by a business. If no firm name is on file, Revenu Québec will display the name under which the business operates.

Validation process

The QST registration number to be validated has 16 characters: ten digits, followed by the letters TQ (for the law concerned) and four more digits.

Example: 9999999999 TQ 0001

Quick and easy

  1. Enter the number you wish to validate.
  2. View the results: status of the QST registration number, effective date of status and business or firm name.
Note
You can validate a GST/HST registration number by consulting the GST/HST registry on the Canada Revenue Agency website.
