Ean13
On this page
The 13-digit barcode number on most products outside North America.
Use it to identify a retail product. The US and Canadian form is a UpcA, a book's number is an Isbn, and your own code is a Sku.
Shape
One value, held as text in one set form, with no parts: 6291041500213.
Example
Ean13("4006381333931")Ean13(raw) checks the text, and text that isn't one breaks the format rule.
text.parse(raw, as: Ean13) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as 4006381333932, 036000291452 or 40063813339310.
Good to know
- It checks its own last digit, so a mistyped number is usually refused.
==tells you whether two are the same.<andlist.sort_bydon't take it.
In JSON
A string, in a request, a response or json.write:
"4006381333931""6291041500213"
