I'm still new to regex (hence not posting this as an answer), but could this do it? [0-9\+\s]+ — John Bustos

Do you have correct inputs and just want to extract the number groups or do you want to test if a given input contains a valid phone number according to your specs? — Seimen

Remove spaces and match plus sign with following numbers:

var input   = 'this is a number +17865 8658 u98765',
    outputs = input.replace(/ /g, '').match(/\+?\d+/g);

Output:

["+178658658", "98765"]

Without replacing spaces:

var input   = 'this is a number +17865 8658 u98765',
    outputs = input.match(/\+?\d( *\d+)+/g);

Output:

["+17865 8658", "98765"]

i do not want to remove spaces keep them as they are like if the number is +16786 876 986 it should detect it but if the number is +1234 u89 97 it should detect two number +1234 and 89 97

it should detect this number a whole number +123 456 788 not as three separate numbers
