A seller's permit is a certificate issued for a small fee by your state (if you live in Canada or the US) that says you are registered to collect sales tax. It is required to buy wholesale and sell retail or sell wholesale, in other words, it is required for retailers who buy or sell tangible, taxable items. If you live outside the US or Canada and your supplier asks for a sales tax ID, usually you just need to provide something equivalent in your country, for example your VAT registration in the EU or the UK, or your ABN or GST registration in Australia and New Zealand.
