Invoice verification
How to verify an FBR invoice
Every FBR digital invoice carries FBR's own invoice number and a QR code. Here is how to check one in under a minute, by app, by SMS or in IRIS, and how to check PRA and SRB bills too.

What a real FBR invoice shows
Before you scan anything, look at the invoice itself. A business on FBR digital invoicing can't hand you an invoice without these.
When a business sends an invoice to FBR, FBR checks it and gives it a number of its own. That number, and a QR code that carries it, are printed on the invoice. They are what make the invoice verifiable.
- FBR's invoice number, separate from the seller's own invoice number. It starts with the seller's NTN or CNIC.
- A QR code holding that FBR invoice number, so it can be checked with a phone.
- The seller's NTN and STRN, and the buyer's details where the buyer is registered.
- Each line with its tax: what was sold, the quantity, the value, the sales tax and the total.
An invoice from a business that should be on FBR digital invoicing, but with no FBR number or QR code, has not reached FBR. Ask the seller for an FBR-numbered invoice before you pay or claim input tax on it.
Many invoices also print FBR's "Digital Invoicing System" logo beside the QR code. eInvoicePro's FBR digital invoicing system puts the FBR number, the QR code and the logo on every invoice it sends to FBR.
Step by step
Four ways to verify an FBR invoice
Use whichever is quickest for you. The app and SMS work for anyone. IRIS is for businesses registered for sales tax.
1. Tax Asaan app
FBR's own mobile app, free on Android and iPhone.
Open FBR POS, tap Verify Invoice, then scan the QR code on the invoice or type the FBR invoice number. The app tells you whether the invoice is verified.
2. SMS to 9966
No app or internet needed. Send a text to 9966 in this format:
INV (space) your CNIC (space) FBR invoice number
FBR replies to tell you whether it holds the invoice.
3. FBR's website
Since February 2026, FBR's website lets buyers confirm that an invoice or bill from an integrated business has reached FBR's system.
Keep the FBR invoice number from the invoice ready before you start.
4. Your purchases in IRIS
For businesses registered for sales tax. Invoices your suppliers send to FBR are loaded into your purchases (Annex-A) when you create your sales tax return in IRIS.
An invoice that isn't there hasn't reached FBR, and is not safe to claim input tax on.
Punjab and Sindh
Verifying PRA and SRB bills
Services in Punjab and Sindh are invoiced to the provincial authorities, not FBR. Their bills carry their own invoice numbers and QR codes.
PRA invoice verification
Bills from Punjab restaurants, hotels, coffee shops, marriage halls and other services go through PRA's E-IMS and carry PRA's invoice number and QR code.
Install PRA's Sahulat app from the App Store or Google Play and scan the QR code on the bill. The app shows whether the bill is genuine.
SRB invoice verification
Bills from SRB-integrated businesses in Sindh, such as restaurants, salons and gyms, are reported to the Sindh Revenue Board as they are made.
Each one carries SRB's invoice number and QR code. SRB also uses these verified POS invoices for its regular prize draws for customers.

Why it matters
Why every buyer now checks their invoices
Since the Finance Act 2026, a bad supplier invoice costs the buyer money, not only the seller.
If an invoice can't be matched
- Since 1 July 2026, the buyer pays 20% of any input tax that can't be matched to the supplier's invoice, and reverses the claim
- The same 20% applies when a listed fake-invoice issuer's input tax isn't reversed within 60 days
- A business that issues an invoice for a fake supply is fined the full value of the invoice and named on a public register
What a quick check gives you
- Confidence that the input tax you claim is backed by an invoice FBR holds
- Suppliers you can keep buying from without surprises at return time
- A clean record if FBR asks about a purchase later
