ELECTRONIC INVOICING
API Verify ID
Check the existence and accuracy of tax codes and VAT numbers, retrieve tax information and avoid errors by ensuring tax compliance
in your workflows.
Correct mistakes
before it's too late.
Three APIs to validate tax data and retrieve company information before issuing the invoice. This service enables the verification of identity of customers and suppliers, reducing the risk of errors, fraud or the use of invalid data and ensuring that every transaction takes place with entities that genuinely exist and are recognized by the tax authorities.

Tax Code Verification
Reliably check the validity of an Italian tax code, making sure it is not only formally correct, but also actually registered with the Revenue Agency.
VAT number verification
Check and retrieve the details of any Italian company using the VAT number:
- Company name
- Company details
- Type of activity (ATECO, REA codes…)
- Financial data (turnover, profits, shareholders, number of employees, share capital…)
Split Payment Verification
Allows you to verify whether a particular organisation or company is subject to Split Payment, that is, that particular tax regime where the debtor of VAT is the client rather than, as normally happens, the contractor.
Using the VAT number or tax code, A-Cube's API obtains:
- Company name
- Type of activity
- SP registration date
