# Generate a random code of 8 numbers

Hi,

For a project I need to generate a code of 8 random numbers. I’m tying to do it with a math function but it’s not working. Little catch it cannot start with the sequence “12xxxxxx”

Hey @Maxkzn. You can generate a random 8-digit number using this
PS: It will never begin with the sequence “12xxxxx”

Thank you so much Is there a way to also remove the 0 of the possible number ?

Yes we can do that as well

just paste this

``````{{floor(random * 9) + 3}}{{floor(random * 9) + 3}}{{floor(random * 9) + 1}}{{floor(random * 9) + 1}}{{floor(random * 9) + 1}}{{floor(random * 9) + 1}}{{floor(random * 9) + 1}}{{floor(random * 9) + 1}}
``````

Thanks but sometime it’s giving results with zero

Try this @Maxkzn
{{floor(random * 7) + 3}}{{floor(random * 7) + 3}}{{floor(random * 9) + 1}}{{floor(random * 9) + 1}}{{floor(random * 9) + 1}}{{floor(random * 9) + 1}}{{floor(random * 9) + 1}}{{floor(random * 9) + 1}}

You can do it this way too,

`{{substring(join(shuffle(split(emptystring + 3456789 + emptystring + 3456789 + emptystring + 3456789; emptystring)); emptystring); 0; 8)}}`
