Output
A JSON response indicating whether the submitted text matches the expected format of a German USt-IdNr (VAT ID), with a result field (e.g. 'processed') and a status field (e.g. 'success') confirming whether the format check passed or failed.
Example use cases
Invoice VAT number pre-submission check
“Before I send this invoice to my German client, can you verify that their VAT number 'DE298635973' has the correct German USt-IdNr format?”
Freelancer onboarding data validation
“I'm onboarding a new German business partner and they gave me 'DE123ABC456' as their VAT ID — can you check if that's a valid German USt-IdNr format?”
E-commerce tax ID cleanup
“I have a customer record with tax ID 'DE 296 123 456' including spaces — can you check if this matches the expected German USt-IdNr format?”
Technical details
Endpoint
POSThttps://kihustle.tech/api/v1/de-ustid-format-checkWhen to prefer
Use this endpoint when you need a lightweight, low-cost format check specifically for German USt-IdNr strings, without performing a live VIES registry lookup. Ideal for pre-validation in invoicing, onboarding, or data-cleaning pipelines where catching obviously malformatted IDs early matters.
Side effects
- Empty or missing text field returns an error or unexpected result
- Non-string input types may cause parsing failures
- Ambiguous input (e.g. partial numbers) may return inconclusive results
- Service may not distinguish format-valid but fake numbers from real registered ones
