Validate the number
First format, length and the country-specific check digit, then the VIES lookup. Back come validity, company name and address as far as the member state discloses them, plus a timestamp and a reference as proof.
Risk VAT fraud
VAT ID valid. And the rest?
VIES says valid or invalid. Enough for reverse charge. For the file you still need proof, document and case.
A check with a timestamp, batch runs and tax rates, plus document and case in one place.
No credit card Timestamped proof per check Single or batch
Trusted by leading companies worldwide
OEM PARTNERSHIP
Hardware giants choose PaperOffice exclusively.
How it works
Validity, tax, document.
A valid number says the company exists in the registry. It does not say whether document, order and partner match.
Batch, rates and quote
Customer and supplier master data run through the same check as a batch. The check also returns a risk assessment for the country of registration from three open sources: the EU VAT gap, the Transparency International corruption perceptions index and the investigation density of the European Public Prosecutor's Office. On top of that come standard and reduced tax rates and the tax quote with reverse charge.
Bring in document and case
The IDP agent reads the VAT ID and the remaining invoice data from an invoice, contract or form, entities link it to partner and earlier documents, the Trust Agent inspects the PDF file for manipulation. On any discrepancy the workflow puts the case in front of a person before approval.
Where VAT checking runs
- Manual Check a single number and file the proof with the case.
- Batch Run your customer or supplier base through in one pass.
- Workflow New partners are checked, flagged and escalated when needed.
- Workspace Every newly filed invoice supplies the number for the check.
- REST API At checkout and during onboarding, from the browser as well.
- MCP Look a number up from Claude, ChatGPT or Cursor.
What this solution covers
Validate, calculate, document.
VAT fraud starts with a number and ends with a document. The two belong together.
- VIES check with proof
Validity, company name and address, plus a timestamp and reference for your accounting.
- Format and check digit
Country-specific patterns are validated before the lookup, so obviously wrong numbers surface immediately.
- When the registry stays silent
Some member states disclose no company data. The result says so explicitly.
- Risk assessment for the country
Three open sources: the EU VAT gap, the corruption perceptions index and the investigation density of the EU prosecutor.
- EU tax rates and reverse charge
Standard and reduced rates per member state, tax quote with reverse charge on a valid ID.
- Manipulation check on the document
The Trust Agent inspects the PDF structure, compares the visible content with the text layer and flags findings.
- The number from the document
IDP reads the VAT ID from invoice, contract or form, entities link it to the partner.
- Whole base in one run
Check customer and supplier bases as a batch and file the results with timestamps.
What PaperOffice solves it with
Six building blocks, one assessment.
The number alone does not carry far. Only with document, partner and log does it become a decision.
VAT Validator VAT validation queries VIES and returns validity, master data and timestamped proof. IDP Agents IDP agents read the VAT ID and the remaining fields from the document, with source locations. Entities Entities link number, company and earlier documents and merge different spellings. Trust Agent The Trust Agent checks whether the matching document was altered inside the PDF. Audit Center The audit centre records every check with result and timestamp in an immutable way. Workflow Agents Workflow agents check new partners and put doubtful cases in front of a person.
Security and compliance
Diligence you can show.
In a tax audit intention counts for little. What counts is proof: which number was checked when, and with what result.

Questions about VAT checking
What you should know before you start.
Where does the validity statement come from?
From VIES, the EU system for confirming VAT identification numbers. Beforehand PaperOffice validates format and check digit locally, so obviously wrong numbers are never sent to the registry at all.
Does PaperOffice rate the risk of a business partner?
Only as far as it is provable. What comes back is the EU register entry (valid or invalid, company name and address where the member state discloses them) plus an assessment of the country of registration from three open sources, each with its own scale. That is a country signal, not a verdict on the company: you decide about the business partner, not the software.
Why are company name and address sometimes missing?
Because not every member state discloses that data through VIES. The result therefore distinguishes an invalid number from a valid number without disclosed master data, instead of letting both look the same.
What happens when VIES is unreachable?
The response reports the status of the check. Unchecked cases can be scheduled for a retry in a workflow or put in front of a person, rather than quietly counting as checked.
Can we check our whole base?
Yes. Customer and supplier bases run as a batch, and a workflow checks new partners as they are created. Results are filed with the case, timestamp included.
Does this help against carousel schemes?
It is not an investigative tool and will not uncover a chain behind your partner. What it does: document the check, tie the number to document and case, surface discrepancies on the document, and put doubtful cases in front of a person before approval.
What is left for the tax audit?
Per lookup a check time and a reference, plus the audit trail across checks, findings and decisions. Exportable as PDF, CSV or JSON, by period or by workspace.
