jQuery validator methods matches   function  value  element  params         var re   new RegExp params          window console log re          window console log value          window console log re test  value         return this optional  element      re test  value       rules            input telf                required    true              matches          d   s                  minlength   10              maxlength   20

Your code   rules        phoneNumber            matches    0-9          lt -- no such method called  matches           minlength 10          maxlength 10           There is no such callback function  option  method  or rule called matches anywhere within the jQuery Validate plugin    EDIT   OP failed to mention that matches is his custom method    However  within the additional-methods js file  there are several phone number validation methods you can use   The one called phoneUS should satisfy your pattern   Since the rule already validates the length  minlength and maxlength are redundantly unnecessary   It s also much more comprehensive in that area codes and prefixes can not start with a 1   rules        phoneNumber            phoneUS  true           DEMO   http   jsfiddle net eWhkv     If  for whatever reason  you just need the regex for use in another method  you can take it from here     jQuery validator addMethod  phoneUS   function phone number  element        phone number   phone number replace   s  g           return this optional element     phone number length  gt  9  amp  amp       phone number match       1-       2-9  d 2     2-9  d 2  -  2-9  d 2 -  d 4          Please specify a valid phone number

If you normalize your data first  then you can avoid all the very complex regular expressions required to validate phone numbers  From my experience  complicated regex patterns can have two unwanted side effects   1  they can have unexpected behavior that would be a pain to debug later  and  2  they can be slower than simpler regex patterns  which may become noticeable when you are executing regex in a loop   By keeping your regular expressions as simple as possible  you reduce these risks and your code will be easier for others to follow  partly because it will be more predictable  To use your phone number example  first we can normalize the value by stripping out all non-digits like this   value     trim value  replace   D g        Now your regex pattern for a US phone number  or any other locale  can be much simpler     1  d 10     Not only is the regular expression much simpler  it is also easier to follow what s going on  a value optionally leading with number one  US country code  followed by ten digits  If you want to format the validated value to make it look pretty  then you can use this slightly longer regex pattern     1   d 3    d 3    d 4      This means an optional leading number one followed by three digits  another three digits  and ending with four digits  With each group of numbers memorized  you can output it any way you want  Here s a codepen using jQuery Validation to illustrate this for two locales  Singapore and US    http   codepen io thdoan pen MaMqvZ

This one is work for me -         d 3      -       d 3   -       d 4

Your regex should be something like   0-9 -     s       It matches numbers  dashes  parentheses and space   If you need something more strict  matching just your example  try this     0-9  10       0-9  3    s  0-9  3  - 0-9  4
