Your first order is #2041, the next one #2047. Customers wonder where the others went.
Why numbers jump
WooCommerce uses the order ID, shared with posts, pages, products and drafts, so numbers skip.
Why it matters
- Customers quote a number on the phone.
- Your accountant expects an order.
- A clear prefix tells your shops apart.
A good format
A short prefix, the year and four digits: WP-2026-0042.
Keep the old numbers
Existing orders keep their number; only new ones follow the new format.
Numberly numbers new orders this way. See the demo.
Frequently asked questions
Are WooCommerce order numbers sequential?
No, they use the post ID, which is shared with other content.
Is this the same as an invoice number?
Not always; check your country’s invoicing rules.
Can I restart each year?
Yes, Numberly can restart on 1 January.
