As far as i understood your question :

function Is-Numeric ($Value)
{
    return $Value -match "^[\d\.]+$"
}

$birds = "owl","crow","robin","wren","jay","123"
foreach ($bird in $birds) { if($bird.length -eq 3 -and (Is-Numeric $bird)) {"$bird"} }

just switch it to your case :)

One solution is while looping through the array names check if the two conditions are met like so:

foreach ($name in "test", "1234567", "test02", "001") {
    if ($name.Length -eq 7 -and $name -match '^\d+$'){
        Write-Host $name
    }
}
