Which customers can already receive an e-invoice?
Paste your customer list and see in one report who is on the Peppol network and who is not. It is the first question before you switch to e-invoicing — and the answer comes straight from the network's own registry.
One customer per line. A VAT number, enterprise number, KVK number or Peppol identifier — with or without the name in front. Pasting straight from a spreadsheet works.
Each number is looked up in public network records, one at a time. The list itself is never sent as a whole and nothing about your customers is stored.
How it works
1. Paste your list
One customer per line, straight from your accounting software or spreadsheet. Names are fine; the scan picks the number out.
2. We look each customer up
In the Peppol network's own registry, not the voluntary directory. Belgian numbers are tried under both registrations.
3. Download the report
Per customer: reachable, not found or unknown, under which number, and through which access point. As CSV, back into your spreadsheet.
Looking up one customer? Use the Peppol check. For the customers who are reachable, make a first invoice right away with the e-invoice generator — or let your accounting software do it through an integration.
Frequently asked questions
Which numbers does the scan recognise?
Belgian enterprise numbers (0123.456.789) and VAT numbers (BE0123456789), Dutch Chamber of Commerce numbers (8 digits) and VAT numbers (NL123456789B01), German, French, Luxembourg and Austrian VAT numbers, GLN codes (13 digits), Dutch government OIN numbers (20 digits) and full Peppol identifiers such as 0208:0123456789. Dots, spaces and quotes from a spreadsheet are fine.
A customer shows 'not found', but they do receive e-invoices.
A company is registered on Peppol under one specific type of number. For Belgian numbers the scan therefore tries both automatically: the enterprise number (0208) and the VAT number (9925). For a Dutch company it depends which number you have: if the customer is registered under their Chamber of Commerce number and you only have the VAT number, the scan will not find them. Put both numbers on the line, or look them up separately with the Peppol check.
What does 'unknown' mean?
That the customer is on the network, but the server holding their details did not answer at that moment — or the lookup itself failed. That is almost always temporary and not a 'no'. Scan those customers again later, or check them individually.
Why does the scan stop after a number of customers?
One address may do 300 lookups an hour; a customer with two possible numbers sometimes counts as two. That comfortably covers a list of a hundred customers. If yours is longer, scan the rest an hour later — the report shows exactly where it stopped.
What happens to my customer list?
It stays in your browser. Each number is looked up individually in public network records — Peppol's DNS layer and the customer's access point — and we store nothing from that except a per-IP counter against abuse. The names on your list never leave your computer: only the number travels with the lookup.
What do I do with the customers who are not reachable?
For now, keep sending them a PDF — and it is worth asking whether they plan to register, especially in Belgium where it has been mandatory since 2026. For the customers who are reachable, the next step is having your invoices leave as e-invoices automatically. That is an integration between your accounting software and an access point; we help with that.
Ready to send to the reachable customers?
We connect your accounting software or web shop to the Peppol network, with this check built in per customer — so every invoice goes the right way on its own.
