BRN vs CRN in Hong Kong 2026:What Tech Founders & E-commerce Entrepreneurs Need to Know
Clear comparison, UBI system update, and practical advice for tech startups and e-commerce businesses on banking, payments, tax filings, and compliance.
Why your BRN is the number that actually matters in 2026
Since Hong Kong fully transitioned to the Unique Business Identifier (UBI) system, the Business Registration Number has quietly become the single most important piece of ID for digital-first companies. Here's why tech founders and e-commerce sellers need to get it right from day one.
One number, everywhere. The BRN/UBI is now the primary identifier for IRD filings, banks, licensing, and marketplaces — replacing the legacy CRN in daily use.
Built for cross-border ops. Non-resident founders use the same BRN as locals. No separate identifier for foreign-owned entities.
Unlocks tax & banking. Required for virtual bank accounts, Stripe, Airwallex, offshore exemption claims, and Profits Tax Return filings.
Platform verification. Amazon Seller Central, Shopify Payments, Lazada, and Shopee all request the BRN/UBI during seller verification.
BRN vs CRN at a glance — 2026 updated comparison
The short version: in 2026, your BRN is the number you'll actually use. Your CRN still exists, but rarely leaves your Certificate of Incorporation.
| Feature | BRN / UBI | CRN |
|---|---|---|
| Issued by | Inland Revenue Department (IRD) | Companies Registry |
| Current status (2026) | Primary identifier — functions as UBI | Historical / legal reference only |
| Format | 8 digits + suffix (e.g. 12345678-000) | 7 digits |
| Main purpose | Tax, banking, payments, licensing, daily operations | Company incorporation record |
| Renewal | Every 1 or 3 years | No renewal required |
| Most used for | Banks, payment gateways, Amazon, IRD, marketplaces | Very rarely needed in 2026 |
What is a BRN (Business Registration Number)?
The BRN is your company's official tax and operational identification number in Hong Kong. It is issued automatically by the Inland Revenue Department within 1–2 working days of successful incorporation.
In the 2026 UBI framework, it functions as your business's universal handle — the number banks, platforms, and government portals will ask for by default.
Key takeaway — If a website, banker, or platform asks for your "Business Registration number," "BR number," "UBI," or "Hong Kong tax ID" — they mean your BRN.
What is a CRN (Company Registration Number)?
The CRN is the number assigned by the Companies Registry at the moment of incorporation. While it still appears on your Certificate of Incorporation, its practical importance has diminished significantly since the introduction of the UBI system.
Today, the CRN is mainly used for specific historical filings with the Companies Registry or certain legal documents. For most tech and e-commerce businesses in 2026, you will rarely (if ever) need to provide your CRN in day-to-day operations.
The 2026 Unique Business Identifier (UBI) system
Since December 2023, Hong Kong has fully transitioned to the Unique Business Identifier (UBI) system. Your BRN now doubles as the UBI and is the single primary identifier for almost all government and commercial interactions.
Practical impact for digital businesses — Banks, fintech platforms, Amazon, Lazada, Shopee, and most government portals now primarily request the BRN/UBI. Your CRN, while still valid, is effectively a background record.
Practical use cases for tech founders & e-commerce entrepreneurs
The BRN touches almost every system you'll plug into as a digital-first company. Here's how it shows up in the two most common founder profiles we serve.

Common pitfalls & practical tips
Most issues we see with new Hong Kong companies come back to one of these three avoidable mistakes.
Confusing BRN with CRN. Giving a bank or marketplace your 7-digit CRN when they asked for the BRN almost always delays verification. Double-check which number the form actually wants.
Missing a renewal window. Unlike the CRN, the BRN must be renewed every 1 or 3 years. Missed renewals can trigger fines, suspended filings, and blocked bank payments.
Skipping the BRN update on key platforms. Banks, payment gateways, and marketplaces don't auto-pull your renewed BRN. Update each system manually after every renewal to keep accounts healthy.
