How to use Invoice Number Generator

Set a prefix, starting year, and counter width, and the tool generates zero-padded sequential invoice numbers, e.g. INV-2026-0001.

Frequently asked questions

Does numbering reset each year?

You control the year segment directly — set it in the pattern, and start the counter at 0001 whenever you want a new year's sequence to begin.

Is this tool free to use?

Yes. This tool is completely free to use with no daily limits and no signup required.

Can I generate more than one at a time?

Most ID generators here support a bulk mode — set the count and copy the whole list at once.
