"Belgium NIT Number Problem: Shopify Payments Activation"

Product Development & Sourcing

Topic summary

A Belgian merchant is unable to activate Shopify Payments due to a formatting conflict with their NIT (National Identification Tax) number. Belgian individual businesses receive 10-digit NIT numbers, but Shopify’s system requires 11 digits.

Suggested solutions:

  • Add a leading zero to the 10-digit NIT (e.g., convert 1234567890 to 01234567890)
  • Try entering the VAT number (BTW/TVA) instead, which may be what Shopify expects
  • Verify the correct number format through company registration details

If these don’t work:

  • Contact Shopify Support directly for manual verification and country-specific assistance
  • Consult Belgian tax authorities to confirm which number is required for payment processing

The issue remains unresolved but potential workarounds have been provided.

Hello Shopify Community,

I’m trying to activate Shopify Payments for my store, but I’m facing an issue with entering my NIT (National Identification Tax) number. In Belgium, the issued number for individual businesses is only 10 digits, while Shopify Payments requires an 11-digit number.

I’ve tried various options but haven’t found a solution yet. Has anyone else in Belgium encountered this issue? How did you resolve it?

Any guidance or suggestions would be greatly appreciated!
Thank you in advance.

Best regards,

Hi @Asfour

I’ve gone through your question and completely understand the issue you’re facing with entering your NIT number for Shopify Payments activation in Belgium. It sounds like a formatting mismatch between Shopify’s system and the Belgian tax ID structure.

Why This Happens:

Shopify Payments typically requires an 11-digit tax ID, while Belgian individual businesses (sole proprietors) are issued a 10-digit NIT. Since the system doesn’t accept the shorter format, this causes an issue when trying to activate payments.

Solution:

Many Belgian merchants facing this issue have resolved it by adding a leading zero (0) before their 10-digit NIT. For example, if your NIT is 1234567890, try entering 01234567890 instead. This aligns the number with Shopify’s 11-digit requirement.

If that doesn’t work, Shopify might be expecting your VAT number (BTW/TVA) instead. You can check this by going to your company registration details and verifying if your VAT number is linked to your business registration.

**Next Steps If It Still Doesn’t Work:**1. Double-check the format – Make sure you’re entering the correct NIT or VAT number associated with your business.

  1. Contact Shopify Support – Since this is a country-specific issue, Shopify Support can manually verify and assist with activation. You can reach them via Shopify Support.
  2. Check with Belgian Tax Authorities – If you’re unsure about the correct number to use, your local tax office may clarify what’s required for online payment processing.

Let me know if you need any more help! Happy to assist further.

Best regards,
Daisy.
