DMS823AA

Official wording from the codebook

MAXIMAAL AANTAL VAN DIT TYPE OVERSCHREDEN

What does the codebook say for this code?

The official wording is: MAXIMAAL AANTAL VAN DIT TYPE OVERSCHREDEN. That text comes straight from the Dutch codebook. We do not translate or shorten it here. The code names the element or the situation. It does not say why that element is wrong on your file. Two consignments with DMS823AA can need a different correction.

Where does this code come from?

DMS823AA sits in table A99 FOUTCD.AANGIFTE of the Codeboek Douane, part UCC declaration handling. That is the list DMS uses when it returns a declaration. AGS or Sagitta numbers from the previous system do not belong here. A German or Belgian code does not either. Source: Codeboek Douane, part UCC declaration handling, table A99 FOUTCD.AANGIFTE, edition 2026-08-29.

Does this error block acceptance?

Table A99 marks DMS823AA as an acceptance-blocking error. The declaration is not accepted for as long as this element is wrong. There is no MRN. Correct the named field and file again.

How do you find the real cause?

Start from the location in the message, not from a list of fixed fixes. Put the named field next to the source document and the master data. Do not guess a cause from DMS823AA alone. The official list changes. This page follows the edition of 2026-08-29. A screenshot from last year can carry different wording. The Nationale Helpdesk Douane points to the codebook, not to a vendor list.
