UK SIC Codes Guide: How Your Activity Affects Banking and VAT in 2026
When filling out your UK company formation application, you will encounter the SIC Code field. For many Arab entrepreneurs, this seems like a minor technical detail, but the truth is that these five digits are your business's "identity card" for UK banks and HMRC. Choosing the wrong code can lead to your Wise or Stripe account being rejected immediately.
In 2026, with updated digital activity classifications, accuracy is paramount. In this guide from Eteform.com, we explain the most important codes for Arab founders and how to choose them.
Top 5 SIC Codes Used by Arab Entrepreneurs
- 47910 - Retail sale via mail order houses or via Internet: The most popular code for Shopify, Amazon, and eBay store owners.
- 62020 - Information technology consultancy activities: Ideal for programmers and software development firms.
- 70229 - Management consultancy activities other than financial: Suitable for trainers and marketing consultants.
- 73110 - Advertising agencies: Dedicated to digital marketing and ad management agencies.
- 82990 - Other business support service activities n.e.c.: A "joker" code used for activities that don't fit a specific category, but not recommended as a first choice for banks.
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.
Steps to Choosing and Changing Your SIC Code (How-To)
Step 1: Research the Activity
Use the official code search tool or consult our Full SIC Code List for Arab Founders.
Step 2: Add More Than One Code
UK law allows you to add up to 4 codes for a single company. If you have an e-commerce store and also provide consulting, you can add both codes.
Step 3: Change When Needed
If you decide to pivot your business, you can update your code at any time via your Confirmation Statement (CS01) filing.
