How to set the order numbers

Hello,

Is it possible to change the order numbers? I need to have orders just with numbers without letters.
The format of order number I need is starting at 00000001 and go on with 00000002, 00000003 ...
The other form of order number I need is starting with 900000001 and go on with 900000002, 900000003 ....

How can I set this?

Thanks

Sincerely
Vaclav

You can configure the order number format with the option "order number format" of the main tab of the configuration:

You could use that format for example:
{id size="8"}

Great! Thanks.
