Just use an auto-incrementing number. Otherwise you’re constantly going to have to check a “random” number doesn’t already exist each time you generate one, as no random number generator is truly random.

@kikismedia Str::random(10)

@martinbean He actually asked for a number, that's alpha-numeric. ;)

In 2 times +
- $rn=rand(0,9).rand(0,9) ... (10 times or better with a loop)
1.1) better with @martinbean solution (Laravel solution versus plain php with rand)
-
Check if this number does not exist for a user
-
redo 1 & 2 if already exists (very low probability)

Here, this is how I generate random 5 digit unique number for each user:
//Generating a random unique candidate_id for each applicant & adding 0 in upfront if id less than 5 digits
$candidatesData = Candidate::get(['candidate_id'])->toArray();
do {
$applicant_id = str_pad(rand(1, 5000), 5, "0", STR_PAD_LEFT);
} while (in_array($applicant_id, $candidatesData));
$candidate = Candidate::create($request->all());
$candidate->candidate_id = $applicant_id;
$candidate->save();
Please consider refactoring the code as per your needs.
