Regex for Mobile Number Validation

by

Satisfies all your requirements if you use the trick told below

Regex: /^(\+\d{1,3}[- ]?)?\d{10}$/

  1. ^ start of line
  2. A + followed by \d+ followed by a or - which are optional.
  3. Whole point two is optional.
  4. Negative lookahead to make sure 0s do not follow.
  5. Match \d+ 10 times.
  6. Line end.

DEMO Added multiline flag in demo to check for all cases

P.S. You really need to specify which language you use so as to use an if condition something like below:

// true if above regex is satisfied and (&&) it does not (`!`) match `0`s `5` or more times

if(number.match(/^(\+\d{1,3}[- ]?)?\d{10}$/) && ! (number.match(/0{5,}/)) )
