Which trades register is this number from?
Canadian trades and contractor numbers come from many agencies, and several share a length. Paste a number to see every register it could fit, then open the matching guide or official register.
Important, up front: this is a shape guess. A seven-digit number, for instance, fits both an ECRA/ESA licence and an Alberta AIT ID. It cannot tell you whether a number exists or is current.

- RBQ licence (Quebec): 10 digits, written XXXX-XXXX-XX.
- ECRA/ESA electrical contractor licence (Ontario): 7 digits.
- Alberta certificate number: usually six digits plus a letter; Alberta AIT ID: 4 to 7 digits.
- TSSA registered fuels contractor (Ontario): FS-R- plus five digits, read from registry listings.
- Technical Safety BC: the guide's example is LGA plus seven digits.
- SkilledTradesBC certificate: the form's example K-01-100111 (entered K01100111).
None of these agencies publishes a check-digit algorithm in the sources cited on the individual guides, so none is implemented here.

Frequently asked questions
How do I tell an RBQ number from an ECRA/ESA number?
By length: an RBQ number has 10 digits (XXXX-XXXX-XX); an ECRA/ESA licence number has 7.
Why does a seven-digit number match two registers?
Alberta AIT IDs run 4 to 7 digits and ECRA/ESA licences are 7 digits. Check where the number came from (an electrical contractor's estimate versus an Alberta apprenticeship record).
Does a match mean the licence is real?
No. It means the shape fits. Confirm on the official register.
