Phone validation regex

Question

I m using this pattern to check the validation of a phone number     0-9 -    9 15     It s works for 0771234567 and  0771234567  but I want it to works for 077-1234567 and  077-1234567 and  077-1-23-45-67 and  077-123-45-6-7  What should I change in the pattern

This solution actually validates the numbers and the format  For example  123-456-7890 is a valid format but is NOT a valid US number and this answer bears that out where others here do not      If you do not want the extension capability remove the following including the parenthesis       s      x   ext   extension  s   d   s         edit  addendum  I needed this in a client side only application so I converted it  Here it is for the javascript folks   var myPhoneRegex             1 s      -  s          s   2-9 1 02-9   2-9  02-8 1  2-9  02-8  02-9     s     2-9 1 02-9   2-9  02-8 1  2-9  02-8  02-9    s      -  s      2-9 1 02-9     2-9  02-9 1  2-9  02-9  2   s      -  s     0-9  4   s     s      x    ext    extension  s   d   s     i  if  myPhoneRegex test phoneVar            Successful match   else          Match attempt failed     hth   end edit   This allows extensions or not and works with  NET           1 s      -  s          s   2-9 1 02-9   2-9  02-8 1  2-9  02-8  02-9     s     2-9 1 02-9   2-9  02-8 1  2-9  02-8  02-9    s      -  s      2-9 1 02-9     2-9  02-9 1  2-9  02-9  2   s      -  s     0-9  4      s      x    ext    extension  s   d        To validate with or without trailing spaces  Perhaps when using  NET validators and trimming server side use this slightly different regex            1 s      -  s          s   2-9 1 02-9   2-9  02-8 1  2-9  02-8  02-9     s     2-9 1 02-9   2-9  02-8 1  2-9  02-8  02-9    s      -  s      2-9 1 02-9     2-9  02-9 1  2-9  02-9  2   s      -  s     0-9  4   s     s      x    ext    extension  s   d   s       All valid   1 800 5551212  800 555 1212   8005551212  18005551212   1800 555 1212 extension65432  800 5551212 ext3333  Invalid  s  234-911-5678  314-159-2653  123-234-5678        EDIT  Based on Felipe s comment I have updated this for international    Based on what I could find out from here and here regarding valid global numbers   This is tested as a first line of defense of course  An overarching element of the international number is that it is no longer than 15 characters  I did not write a replace for all the non digits and sum the result  It should be done for completeness  Also  you may notice that I have not combined the North America regex with this one  The reason is that this international regex will match North American numbers  however  it will also accept known invalid   such as  1 234-911-5678  For more accurate results you should separate them as well    Pauses and other dialing instruments are not mentioned and therefore invalid per E 164         0-9  1 3      -  0-9  1 3   -  0-9  3 5   -  0-9  4    -  0-9  3      With 1-10 letter word for extension and 1-6 digit extension         0-9  1 3      -  0-9  1 3   -  0-9  3 5   -  0-9  4    -  0-9  3       w 1 10  s  d 1 6      Valid International  Country name for ref its not a match     55 11 99999-5555 Brazil   593 7 282-3889 Ecuador    44  0848 9123 456 UK   1 284 852 5500 BVI   1 345 9490088 Grand Cayman   32 2 702-9200 Belgium   65 6511 9266 Asia Pacific   86 21 2230 1000 Shanghai   9124 4723300 India   821012345678 South Korea  And for your extension pleasure    55 11 99999-5555 ramal 123 Brazil   55 11 99999-5555 foo786544 Brazil  Enjoy

Consider        0-9  3 -  0-9  6 12     This only allows   at the beginning  it requires 3 digits  followed by an optional dash  followed by 6-12 more digits   Note that the original regex allows  phone numbers  such as 70 12---12 92  which is a bit more liberal than you probably had in mind     The question was amended to add       077-1-23-45-67 and  077-123-45-6-7   You now probably need to be using a regex system that supports alternatives        0-9  3 -   0-9  7   0-9 - 0-9  2 - 0-9  2 - 0-9  2   0-9  3 - 0-9  2 - 0-9 - 0-9      The first alternative is seven digits  the second is 1-23-45-67  the third is 123-45-6-7   These all share the optional plus   followed by 3 digits and an optional dash - prefix   The comment below mentions another pattern       077-12-34-567   It is not at all clear what the general pattern should be - maybe one or more digits separated by dashes  digits at front and back        0-9  3 -  0-9  - 0-9        This will allow the   077-  prefix  followed by any sequence of digits alternating with dashes  with at least one digit between each dash and no dash at the end

I have a more generic regex to allow the user to enter only numbers     -  whitespace and     It respects the parenthesis balance and there is always a number after a symbol           s0-9      d 3       0-9         -    s   0-9      false     false    48 504 203 260    false    48 504 203 260  false    55 123  456-78-90-  false    55 123  - 456-78-90  false   504 203 260  false      false   -  false       false            false    21 7777  false    48  21   false      true     1  true    1  true   555-5555-555  true    48 504 203 260  true    48  12  504 203 260  true    48  12  504-203-260  true    48 12 504203260  true    4812504203260  true   4812504203260
