help with regex validation for worldwide email, phone numbers and address

Create a short answer question for the phone number. Click on the three dots (⋮) at the bottom right of the question field and select "Response validation." In the dropdown that appears, select "Regular expression." Choose "Matches" from the next dropdown. Paste the regex pattern into the text field. Add a custom error message if desired, such as "Please enter a valid phone number starting with a + followed by the country code and number." ^\+([0-9]{1,4})[-\s]?([0-9]{1,15})$ This regex should cover a wide range of international phone numbers, but keep in mind that certain country-specific formatting might not be fully captured due to the flexibility required for worldwide usage. If you encounter any specific cases where the regex fails, you may need to adjust the pattern slightly. More on reddit.com

Use this regex:

 String PHONE_PATTERN = "^(?:00|\\+)[0-9\\s.\\/-]{6,20}$";

if you have removed spaces, hyphens and whatever from the number, and you want to catch either +xxnnnnnnnn or 00xxnnnnnnnn where xx is the country code of course and n is the 9 digit number OR 0nnnnnnnnn where a non international number starting with a zero is followed by 9 digits then try this regex

regex - Regular expression to match standard 10 digit phone number - Stack Overflow

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

Matches the following

123-456-7890
(123) 456-7890
123 456 7890
123.456.7890
+91 (123) 456-7890

If you do not want a match on non-US numbers use

^(\+0?1\s)?\(?\d{3}\)?[\s.-]\d{3}[\s.-]\d{4}$

Update :
As noticed by user Simon Weaver below, if you are also interested in matching on unformatted numbers just make the separator character class optional as [\s.-]?

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

https://regex101.com/r/j48BZs/2

There are many variations possible for this problem. Here is a regular expression similar to an answer I previously placed on SO.

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

It would match the following examples and much more:

18005551234
1 800 555 1234
+1 800 555-1234
+86 800 555 1234
1-800-555-1234
1 (800) 555-1234
(800)555-1234
(800) 555-1234
(800)5551234
800-555-1234
800.555.1234
800 555 1234x5678
8005551234 x5678
1    800    555-1234
1----800----555-1234

Regardless of the way the phone number is entered, the capture groups can be used to breakdown the phone number so you can process it in your code.

Group1: Country Code (ex: 1 or 86)
Group2: Area Code (ex: 800)
Group3: Exchange (ex: 555)
Group4: Subscriber Number (ex: 1234)
Group5: Extension (ex: 5678)

Here is a breakdown of the expression if you're interested:

^\s*                #Line start, match any whitespaces at the beginning if any.
(?:\+?(\d{1,3}))?   #GROUP 1: The country code. Optional.
[-. (]*             #Allow certain non numeric characters that may appear between the Country Code and the Area Code.
(\d{3})             #GROUP 2: The Area Code. Required.
[-. )]*             #Allow certain non numeric characters that may appear between the Area Code and the Exchange number.
(\d{3})             #GROUP 3: The Exchange number. Required.
[-. ]*              #Allow certain non numeric characters that may appear between the Exchange number and the Subscriber number.
(\d{4})             #Group 4: The Subscriber Number. Required.
(?: *x(\d+))?       #Group 5: The Extension number. Optional.
\s*$                #Match any ending whitespaces if any and the end of string.

To make the Area Code optional, just add a question mark after the (\d{3}) for the area code.

r/GoogleForms on Reddit: help with regex validation for worldwide email, phone numbers and address

July 31, 2024 -

Hello, posting here in case someone can help. I need to add some sort of data validation in google forms for international phone numbers, the rules I have are:

The numbers should start with a plus sign ( + )
It should be followed by Country code and National number 1 to 4 digits between 0 and 9
It may contain white spaces or a hyphen ( – ).
the length of phone numbers may vary from 7 digits to 15 digits.

The form is going to be available to people that are based worldwide so it needs to be flexible enough to cover most countries. I've searched online extensively as this is quite common but my phone numbers keep getting errors, anyone has one that works? Thank you

Create a short answer question for the phone number. Click on the three dots (⋮) at the bottom right of the question field and select "Response validation." In the dropdown that appears, select "Regular expression." Choose "Matches" from the next dropdown. Paste the regex pattern into the text field. Add a custom error message if desired, such as "Please enter a valid phone number starting with a + followed by the country code and number." ^\+([0-9]{1,4})[-\s]?([0-9]{1,15})$ This regex should cover a wide range of international phone numbers, but keep in mind that certain country-specific formatting might not be fully captured due to the flexibility required for worldwide usage.
