Standard Industrial Classification (SIC) Codes — 2026 Guide

Standard Industrial Classification (SIC) Codes — 2026 Guide

Every UK Limited Company must have at least one **SIC Code** (Standard Industrial Classification). This 5-digit number is the official way the UK government categorizes what your business does. For Arab founders, choosing the right SIC code is not just a formality; it's a critical part of your "Identity" that banks like Wise and Stripe use to assess your risk profile. In 2026, using a code that accurately reflects your digital business model is the foundation of a healthy compliance status.

In this guide from Eteform.com, we simplify the SIC code system and help you choose the best one for your venture.

How SIC Codes Work

The system is hierarchical, dividing the entire economy into sections (like "Retail," "Information," or "Professional Services"). When you form your company with Eteform, you select the code that most closely matches your main source of income.

Top SIC Codes for Digital Entrepreneurs in 2026

1. 47910 — Retail sale via mail order houses or via Internet: The "Holy Grail" code for Dropshippers, Amazon sellers, and e-commerce stores.
2. 62012 — Business and domestic software development: Perfect for SaaS founders and mobile app developers.
3. 70229 — Management consultancy activities (other than financial): The standard code for business consultants, marketing experts, and strategy advisors.
4. 74909 — Other professional, scientific and technical activities n.e.c.: A "Catch-all" code for various digital services like SEO, copy-writing, or virtual assistance.
5. 82990 — Other business support service activities n.e.c.: Often used by holding companies or diverse digital agencies.

How Your SIC Code Affects Your Bank Account

Banks like Wise Business and Revolut perform automated reviews. If you choose a code related to financial services (like 64990) or real estate when you are actually selling clothes, you will be flagged as "High Risk," and you will be asked for impossible documentation or rejected outright.

Golden Rule: Your business description on your website must match the SIC code registered with Companies House.

The Impact of SIC Codes on VAT

When you apply for VAT registration, HMRC looks at the activity code to determine if you qualify for certain tax schemes (like the Flat Rate Scheme). A mismatch between the code and your actual sales invoices raises red flags and may lead to a tax audit.

Why Update Your SIC Code?

1. Banking Accuracy: Banks like Wise or Revolut monitor your activity. If your code says "Education" but your bank statements show "Shoe Sales," your account may be flagged for review.
2. Government Statistics: It helps the UK government track economic trends correctly.
3. Professional Credibility: When partners or investors look up your company on the public register, they should see a description that matches your current business model.

How to Change Your SIC Code (How-To)

Step 1: Find the New Code

There are over 700 codes to choose from. See our Comprehensive SIC Code Guide to find the one that best fits your new activity.

If you need the change to show on the public record immediately (e.g., for a bank application), you can choose to file a Confirmation Statement early. At Eteform, we can handle this "Early Filing" for you.
