The seller city is missing
The `Seller city` element (BT-37) must be provided.
Only the issuer holds this value: Factlint reports it and never fabricates it. Test your invoice to find out whether it is affected.
The message your validator prints
Copied verbatim from the sealed artefact: this is the exact sentence the check prints when this rule fails.

Common searches around this code
These phrases mirror what an integrator searches for: code, syntax, rule, business field and correction.
Test your file with this error in mind
Upload the invoice involved: the report will say whether this code appears, where it appears in the document, and whether Factlint can only report it or also fix it.
To automate this check in an ERP flow, call the validation API and link every returned code to its public page.
Why this error happens
EN 16931 reduces the seller's postal address to the country; XRechnung adds the city and the post code. A truncated address therefore passes European validation and fails here, with nothing having changed in the document.
How to fix it
Complete the seller's address in your master data. The city does not follow from the post code: several towns share one.
