Where do these tools come from?

From our daily work
These are the real checks we run on MRN-closure orders — packaged for self-service.
Official data sources
The ISO 6346 standard, European Commission databases (MRN follow-up, VIES, the EORI register), NBP exchange rates and the German terminal systems.
No sign-up, no trace
No accounts. The numbers you check are not stored in any database — unless you choose to leave us a request to handle.

The tools are free and will stay free. Our real work starts where self-service ends: we close MRNs in the ZAPP/EMP, BHT, WHT, Portbase and APCS port systems — from filing to the CC599C.

Frequently asked questions

Are the tools free?

Yes - all tools are free and will stay free. They are the self-service version of the checks we run on MRN-closure orders.

Do I need an account?

No. None of the tools require registration, and the numbers you check are not archived anywhere - unless you choose to leave us a request to handle.

Where does the data come from?

From official sources: the ISO 6346 standard, European Commission databases (MRN follow-up, VIES, the EORI register), NBP exchange rates and the German terminal systems (EUROGATE, HHLA, NTB).

What does CloseMRN actually do?

We close MRNs: we register declarations in the ZAPP/EMP, BHT, WHT, Portbase and APCS port systems and drive them to the CC599C/IE599 export confirmation. The tools are a taste of that service.

We cover 8 European ports. Average filing time 32 minutes, 2h order acceptance guarantee.
