Posted on by Jake_Loeb

I'm starting to transition our forms to RTM, and when i tried to use the default phone number validation I'm not able to actually submit a valild phone number. Below is the regular expression value I pulled from the html. Does anyone know what phone number format this is trying to get as 555-555-5555 didn't work.
^(//+[(]?[0-9]{1,4}|[(]?00[0-9]{0,2}|[(]?011[0-9]?|[(]?010[0-9]?)[)]?([ //-()]*[0-9][ //-()]*){3,16}$

Hi,

This regular expression corresponds to a phone number in the format:
The phone number is spliced from two sets of digits.
The first set of digits has four cases:
Case 1:
+(1 to 4 digits) ,'(' and ')' are optional.
Example: +1, +(1234)
Case 2:
00(0 to 2 digits) ,'('and')' are optional.
Example: 00, 00(), 00(1)

Case 3:
(011 One digit optional), '('and')' are optional.
Example: 011, 0111, (011), (0111)

Case 4:
(010 One digit optional), '('and')' are optional.
Example: 010, 0101, (010), (0101)

Spaces, dashes, and parentheses can be inserted between the second set of digits. The quantity of these three types of characters to be inserted: 0 or more. The second group has no less than 3 and no more than 16 digits.
For example: 555, 555-555-5555, 555 555 5555, 555-555 5555

Therefore, the complete example of a phone number is as follows:
+(1234)555-555-5555, 00555-555-5555, 011 555-555-5555, 010-555-555-5555
