Random zip code generator

Generate random postal codes that match a country's format: US, UK, Canada, India, Australia, or Germany, one per line, ready to copy as test data.

Pick a country format and the code list appears here.

These codes are format-valid, not real. Nothing checks them against a postal database, so many will not be assigned or deliverable, and UK and Canadian codes point at random places. Keep them as strings everywhere they travel: spreadsheets and JSON consumers that coerce to numbers strip the leading zeros that US, Indian, and German codes legitimately start with.
