Company Registration Number
A Company Registration Number (CRN) is a unique identification number issued by the Securities and Exchange Commission of Pakistan (SECP) when a business is incorporated. This number officially represents the legal identity of the company in Pakistan’s corporate ecosystem. It appears on the Certificate of Incorporation, which proves that a company is formed under the Companies Act, 2017.
Just like an individual has a CNIC number, a company’s identity in the legal and business world is its CRN.
Format of the Company Registration Number
The CRN is a numeric or alphanumeric code that is unique for each company. Its structure may differ slightly based on the SECP’s internal classification system, but it typically follows one of these formats:
-
0054321 (7 digits) for older companies
-
CUIN-0123456 for newer companies (CUIN stands for Corporate Unique Identification Number)
Some companies may be assigned a CRN starting with CUIN followed by a digit sequence.
Who Issues the Company Registration Number in Pakistan?
The SECP is the only authority responsible for issuing company registration numbers. It is generated once a company has completed the incorporation process on the SECP eServices portal, and has submitted all legal documents including:
-
Memorandum of Association (MoA)
-
Articles of Association (AoA)
-
CNICs or passports of directors
-
Proof of registered office
-
Name reservation approval
Once approved, SECP issues the Certificate of Incorporation, which includes the company name, registration number, and date of registration.
Where Can You Find Your Company Registration Number?
If you’re a director, shareholder, or the person who registered the company, you can find the CRN in:
-
The SECP Certificate of Incorporation (top section)
-
SECP eServices dashboard, under your company profile
-
Registered email inbox (SECP also sends a copy of the certificate via email)
If you are not part of the company but want to verify another business, you can use SECP’s public search system by company name to find its CRN and legal status.
Why is the Company Registration Number Important?
The CRN is critical for:
-
Legal Recognition: Confirms that the company exists as a separate legal entity
-
Opening a Business Bank Account: Banks require a copy of the incorporation certificate with CRN
-
Registering with FBR: Needed to apply for National Tax Number (NTN) and file tax returns
-
Issuing Invoices and Contracts: Most government departments and corporations require CRN for B2B contracts
-
Import/Export Registration: CRN is required to register with customs or obtain a WEBOC ID
-
Participating in Government Tenders: Public procurement requires a valid CRN
-
Investor and Partner Trust: CRN provides business legitimacy
Company Registration Number vs. NTN vs. STRN
Number Type | Issued By | Purpose |
---|---|---|
Company Registration No | SECP | Legal existence of company |
NTN (National Tax No) | FBR | Tax identity for income tax filing |
STRN (Sales Tax No) | FBR | Identity for sales tax compliance |
All three numbers are important for companies operating in Pakistan, and each serves a different but related purpose.
How to Verify a Company Registration Number in Pakistan
You can check the validity of a company registration number in three ways:
1. SECP Company Search

Use SECP’s online company database. Enter the company name or registration number. You will see the official details, including the date of incorporation, legal status (active, dissolved), and registered office.
2. Company Certificate
Incorporation Certificate Sample
Ask the company to share its Certificate of Incorporation. This document proves their registration with SECP and includes the CRN.
3. Through Professional Services
Law firms and tax consultants in Pakistan often use SECP and FBR portals to validate companies before signing contracts or engaging in transactions.
Can a Company Have More Than One Registration Number?
No. Each company receives only one permanent company registration number upon incorporation. If the company changes its name, address, or ownership, the CRN remains the same. However, if a company is dissolved and re-registered later, it will receive a new CRN.
Can I Use My Company Registration Number as NTN?
No. A company registration number is separate from your NTN (National Tax Number). While both are required, they are issued by different authorities—SECP issues the CRN; FBR issues the NTN.
How Long Does It Take to @Get a Company Registration Number?
Once the incorporation application is submitted on SECP’s eServices platform with all documents, the registration number is usually issued within 1 to 3 working days. The entire process is now digital, making it faster and more efficient than traditional methods.
Is the Company Registration Number Confidential?
No. Company registration numbers are public information and are available on the SECP portal. Anyone can verify a company using its name or CRN to check its legal status. However, financial information, shareholding ratios, and meeting minutes remain confidential.
Conclusion
A Company Registration Number is the backbone of your business identity in Pakistan. It legally proves that your company exists and allows you to operate within the formal economy. Whether you’re starting a new business, verifying a supplier, or applying for government licenses, understanding and correctly using your CRN is essential. Always keep a copy of your Certificate of Incorporation and ensure your CRN is correctly mentioned on contracts, invoices, and bank documents. It is the first step to building trust, credibility, and long-term success.
