How to add a VAT registration number

If your organization has a valid UK VAT registration number, you can add it to your billing profile in the Certn client portal.

Your VAT registration number is used to determine how VAT is applied to invoices associated with that billing profile.

Add your VAT registration number

1. Log in to the Certn client portal.
2. Go to Billing Profiles.
3. Select the billing profile you want to update. If you do not have a billing profile yet, create a new one.
4. Enter your organization's VAT registration number in the Tax registration number field.
5. Select Save.

Before you add your VAT number

Make sure you enter your organization's VAT registration number exactly as it was issued by the applicable tax authority.

UK VAT registration numbers generally begin with GB, followed by the applicable registration digits or government identifier.

If your organization has multiple billing profiles, make sure the VAT registration number is added to each applicable profile.

VAT registration numbers cannot be added to applicant-pay billing profiles.

Changes to existing invoices

Your VAT registration information is recorded when an invoice is generated. Adding or changing a VAT registration number does not automatically update invoices that have already been issued.

If you have updated your VAT registration number and believe an existing invoice needs to be corrected, please contact Certn Support for assistance.

Where the VAT registration number will appear

Future invoices will have the VAT number noted on the upper right of the invoice, on the second line. Please see a sample invoice with a VAT registration number below:
