validating 10 digit phone number

I am new to RegEx I am trying to validate a phone number with 10 digit and + and 2 digit country code as optional. Tried with few regex but I'm not able to make + and the country code as optional ^[+]*\d[0-9]{10,12}$. Can anyone tell me where I'm wrong. Thanks in advance.

If I understand your question correctly (it's a bit fuzzy with the optional part), none of the given answers will do what you want. So here's my go at it ;)

^(?:\+\d\d)?\d{10}$

This starts with an optional non capturing group with the + and the country code. Then followed by the 10 digits.

See it here at regex101.

Are you using Html5 pattern? if yes, below could be your answer,

<input type="text" pattern="[\+][\(]\d{2}[\)]\d{10}" required/>

e.g. format: +(91)1234567890

You can try this 

^([0|\+[0-9]{1,5})?([7-9][0-9]{9})$

You need to enclose the first two digits with an optional non-capturing group:

^[+]?(?:[0-9]{2})?[0-9]{10}$
     ^^^^^^^^^^^^^

See the regex demo.

Details:

  • ^ - start of string
  • [+]? - an optional +
  • (?:[0-9]{2})? - an optional sequence of 2 digits
  • [0-9]{10} - 10 digits
  • $ - end of string.
