You can use range quantifier  min max  to specify minimum of 1 digit and maximum of 6 digits as     0-9  1 6     Explanation           Start anchor  0-9    Character class to match one of the 10 digits  1 6    Range quantifier  Minimum 1 repetition and maximum 6          End anchor   Why did your regex not work    You were almost close on the regex     0-9  0-9    0-9    0-9    0-9    0-9       Since you had escaped the   by preceding it with the     the   was no more acting as a regex meta-character   for 0 or 1 repetitions  but was being treated literally   To fix it just remove the   and you are there   See it on rubular   The quantifier based regex is shorter  more readable and can easily be extended to any number of digits   Your second regex     0-999999     is equivalent to     0-9     which matches strings with exactly one digit  They are equivalent because a character class  aaaab  is same as  ab
