Question

I\'m using this pattern to check the validation of a phone number

^[0-9\\-\\+]{9,15}$

It\'s works for 0771234567 and +0

Answer 1

Adding to @Joe Johnston's answer, this will also accept:

+16444444444,,241119933

(Required for Apple's special character support for dial-ins - https://support.apple.com/kb/PH18551?locale=en_US)

\(?\+[0-9]{1,3}\)? ?-?[0-9]{1,3} ?-?[0-9]{3,5} ?-?[0-9]{4}( ?-?[0-9]{3})? ?([\w\,\@\^]{1,10}\s?\d{1,10})?

Note: Accepts upto 10 digits for extension code

Answer 2

Here is the regex for Ethiopian Phone Number. For my fellow Ethiopian developers ;)

phoneExp = /^(^\+251|^251|^0)?9\d{8}$/;

It matches the following (restrict any unwanted character in start and end position)

• +251912345678
• 251912345678
• 0912345678
• 912345678

Answer 3

This regex matches any number with the common format 1-(999)-999-9999 and anything in between. Also, the regex will allow braces or no braces and separations with period, space or dash. "^([01][- .])?(\(\d{3}\)|\d{3})[- .]?\d{3}[- .]\d{4}$"

Answer 4

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.

Answer 5

^(\+\d{1,2}\s)?\(?\d{3}\)?[\s.-]\d{3}[\s.-]\d{4}$

Matches the following cases:

123-456-7890

(123) 456-7890

123 456 7890

123.456.7890

+91 (123) 456-7890

Answer 6

Try this

\+?\(?([0-9]{3})\)?[-.]?\(?([0-9]{3})\)?[-.]?\(?([0-9]{4})\)?

It matches the following cases

• +123-(456)-(7890)
• +123.(456).(7890)
• +(123).(456).(7890)
• +(123)-(456)-(7890)
• +123(456)(7890)
• +(123)(456)(7890)
• 123-(456)-(7890)
• 123.(456).(7890)
• (123).(456).(7890)
• (123)-(456)-(7890)
• 123(456)(7890)
• (123)(456)(7890)
