Pakistan NTN Format Checker
Check that a Pakistan National Tax Number (NTN) for a company or AOP has the correct format — 7 digits and a check digit.
What is a Pakistan NTN?
A National Tax Number (NTN) is the income-tax registration number the Federal Board of Revenue (FBR) assigns to taxpayers. For companies and associations of persons it is 7 digits, usually printed with an eighth digit after a hyphen — for example 1521191-6 for TRG Pakistan Ltd. Individuals use their 13-digit CNIC as their NTN.
Pakistan NTN format (companies and AOPs)
Seven digits, usually printed with an eighth digit after a hyphen.
(reported check digit)
Example: 1521191-6 (TRG Pakistan Ltd, as printed on its website).
- 8 digits: Enter all 8 digits, with or without the hyphen.
- Check digit: The eighth digit is reported to be a check digit; FBR has not published a formula.
- Not an NTN: A 13-digit STRN is a separate sales-tax number; a 13-digit CNIC is an individual’s NTN and personal data.
- Format check only: This checker confirms the format. It does not query FBR or show Active Taxpayer List status.
How to check a Pakistan NTN
- 1 Find the NTN on the supplier’s invoice or registration certificate.
- 2 Enter all 8 digits above. The checker confirms the format.
- 3 To confirm registration and ATL status, use FBR’s online ATL check, or SMS “ATL”, a space and the 7-digit NTN (without the digit after the hyphen) to 9966.

Frequently Asked Questions
What is the format of a Pakistan NTN?
FBR issues companies and associations of persons a 7-digit NTN. It is usually printed with an eighth digit after a hyphen, reported to be a check digit — for example 1521191-6 for TRG Pakistan Ltd. Individuals with a CNIC use it as their NTN; non-residents without one use their passport number.
How do I check if a business is on the Active Taxpayer List (ATL)?
The Federal Board of Revenue (FBR) offers three ways: the online ATL check on its e-portal, an SMS to 9966, or downloading the published list. Our checker confirms the NTN’s format only, not ATL status.
What is the difference between NTN and STRN?
The NTN is the income-tax number. The STRN (Sales Tax Registration Number) is a separate 13-digit number for sales-tax registrants, and FBR has stated that quoting the NTN is not a substitute for the STRN.
What happens if a supplier is not on the ATL?
Tax deducted or collected from persons not on the ATL is generally doubled, and further sales tax applies to supplies to unregistered or inactive buyers. Checking ATL status before paying is therefore common practice.
Does the NTN have a check digit?
The eighth digit printed after the hyphen is reported to be a check digit, but FBR has not published how it is calculated, so a format check cannot prove an NTN is registered.
Do individuals have a separate NTN?
No. Since tax year 2015 an individual’s NTN is their 13-digit CNIC. A CNIC is personal data, so this page uses company examples only.
