Hi all, I need to create a lot of unique codes for a client (into the tens of thousands). Does anyone know of a website where you can specify the format for the code and then it just outputs this for you?

Thanks

EDIT: I found one after I posted this that does up to 20,000. Nevermind.

I was gonna say Excel

=RANDBETWEEN(10000,99999)

copy it down, copy and paste the whole lot as 'values' then do a 'remove duplicates'

Why bother with random?
A consecutive list from 10000-99999 would be pretty much the same.

And they'd be easily guessable if he's using "ten of thousands" of codes from that select list.

I think non-sequential alpha-numeric codes might be a bit more secure...

Yes, sorry, i wasnt suggesting that way was a good idea. Just that randomising it then removing duplicates is not a particularly efficient way of producing that list.

He said he wanted the numbers to 'random'

I misread, I thought the 'codes' he wanted had to be 5 figures long.

It'd take me less than a minute, how much more efficient do you want, It's certainly quicker than typing up a thread on here about it.

Your method would eventually give every number between 10000-99999. It doesnt matter what order they are in if you include every number.

He said he wants a lot of codes. Once he starts to get towards the end of the possible numbers that your method creates, it would start to take a long time.
...produce random number
...remove duplicates (random number gets removed because it's a duplicate)
...repeat until a non duplicate is produced.

http://www.techzoom.net/tools/password-generator.en

Use that, specify your options, select 10,000 if it can and hit go!

Edit: Fail it can only do 32 at a go! Well google for online random password generator

Edit2: http://www.createpasswords.com/Secure/10/1000/index.html Here you go, do this 10 times

Wolfram Alpha can do this but I'd imagine it'd be pretty painful one at a time unless there's some form of api you can use to get the functionality.

From a linux shell:

pwgen 10 -N 20000 -s -1 > codes.txt

Change the 10 for the length of chars and change the 20000 to the number of codes you want to generate.

As I already said, I misread. I thought he wanted an unspecified number of random numbers in the tens of thousands (5 digits). So I wasn't advising taking 10 thousand random numbers between 10000 & 99999.

My mistake.
