FBR invoice number checker
Every invoice successfully transmitted under the digital invoicing regime is assigned a unique 22-digit FBR invoice number, printed on the invoice with a QR code. Paste a number to check it matches the format.
A valid format does not by itself prove the invoice exists on FBR record — it only confirms the number is well-formed. To verify authenticity, scan the invoice QR code with the FBR Tax Asaan app.
Muhasib returns this number automatically every time you transmit an invoice.
