For data corrections, privacy requests, partnerships or help with the lookup tools, email us. We aim to reply within two business days.
Support
Email support@postcode.dog for questions about lookup results, batch checks, formats or the guides. Include the country and the post code or place you are checking so we can reproduce the issue.
Data corrections
If a post code, place or region is wrong or missing, send the country, code, place and the result you expected. A link to an official or carrier source helps us verify and update the data faster.
Privacy requests
For access, correction, deletion or other privacy requests, email support@postcode.dog with the subject “Privacy request”. See Privacy Choices for the rights available and the verification process.
Partnerships and press
For data partnerships, integration questions or press enquiries, use the same address and tell us a little about your use case and expected volume.
What we cannot help with
We cannot confirm delivery, customs clearance or carrier acceptance, and we do not provide legal advice. For a shipment, always confirm the address and label format with the carrier.
