Bulk check of counterparty tax codes
Paste a list of supplier or customer tax codes — up to 100 codes per check. The result shows each code's status, province and the date it was recorded; click any number to filter out the codes that need a closer look, then download a CSV that opens in Excel. Free, no sign-up, and your list is not stored.
How to use it
- Paste the list. Copy the tax code column from Excel or your accounting software and paste it into the box above — one code per line is easiest; commas, spaces and dots inside codes are removed automatically. Branch codes may be written
0101234567-001or0101234567001. - Read the summary. Duplicates are merged, invalid codes separated, then codes are counted by status. Click any number to filter the table to exactly those codes — for example click "need a closer look" to list counterparties that are suspended, not operating at their registered address or have no status.
- Read the guidance by status. Each group that needs a closer look comes with steps to take; each row links to the company profile and to an explanation of its status.
- Download CSV. The "Download CSV" button saves exactly the rows shown (after filtering); Excel keeps the leading zero of each tax code.
Example: paste the 60 supplier codes for the quarter; the result might be 55 active, 2 temporarily suspended for a fixed term, 1 not operating at its registered address and 2 not in the database. Click "1" next to not operating at registered address to isolate that code, read the guidance, then check again on the tax authority's page before accepting further invoices. Only need one code? Use the single tax code status check.
Data compiled from public sources; each row shows the date last recorded and may lag behind the official source. It is not a confirmation by a government agency and does not show whether a company owes tax or has done anything wrong. Official status: the tax authority's taxpayer information lookup page. TaxDatum.com is run by a private company and is not a government portal. The list you paste is not stored.
Questions about the bulk check
What is the bulk tax code check for?
For accountants and purchasing teams to review a list of suppliers or customers in one go: which tax codes are active, temporarily suspended, not operating at their registered address or not in the database. Up to 100 codes per check; results can be filtered by status and downloaded as a CSV file that opens in Excel.
Is the list of tax codes I paste stored?
No. The list is only used to run that one check and is then discarded; the system stores neither the list nor the results. The CSV file is created in the browser of the device you are using, from the results table. The usage log records only how many codes were checked, not which ones.
Is the result here the official status?
No. The data is compiled from public sources; each row shows the date last recorded and may lag behind the official source. The official status is on the tax authority's taxpayer information lookup page. TaxDatum is run by a private company and is not a government portal.
A partner shows "not operating at registered address" — does that mean fraud?
That cannot be concluded from one status. A status describes the registration situation; it does not say whether a company owes tax or has done anything wrong. The sensible steps are to check again on the tax authority's page, ask the partner directly, pause accepting new invoices and review invoices already received — each status in the results has specific guidance.
Why are some codes not found in the database?
The aggregated database does not yet cover every company, branch and household business. Not being in the database does not mean the tax code does not exist. Check each digit again (10 digits for a company; a branch adds a hyphen and 3 digits), then look up each code on the tax authority's page.
