(123) 456-7890
123 456 7890
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}$

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/regex on Reddit: Extracting 10 digits from phone numbers
January 8, 2025 -
I'm completely new to regular expressions as of this morning.
I'm trying to trim phone numbers to their 10 digit numbers, removing the 1 and +1 variants in my data. I've figured out that I can use (.{10}$) to get the last 10 numbers of a phone number. The problem seems that it's removing the 10 digits and leaving what's left, 1 and +1. I've told it to use $1 but no luck. Can someone help?

How do your input strings look like? If you just want to remove everything except for the last 10 characters, you can replace ^.*(?=.{10}$) with nothing, or replace ^.*(.{10})$ with $1. This doesn't work with punctuation or whitespace or anything else inside the digits. You can use \d or [0-9] instead of "." to make sure you actually match digits on the right hand side.

Maybe something like this abomination? ^.*?(?:\b|\+?\b1)?(?: |\p{P})*(\d)(?: |\p{P})*(\d)(?: |\p{P})*(\d)(?: |\p{P})*(\d)(?: |\p{P})*(\d)(?: |\p{P})*(\d)(?: |\p{P})*(\d)(?: |\p{P})*(\d)(?: |\p{P})*(\d)(?: |\p{P})*(\d)\b.*$ and replacing it with $1$2$3$4$5$6$7$8$9${10} It captures each of the 10 digits (allowing optional space-or-punctuation between them) optionally prefixed by a 1 or +1. For the entire line worth of input it gets replaced with just each of the 10 captured-digits. I tried to create a regex101, but was getting "There was an error trying to save your regex. Please try again later." Here's the sample data I threw at it, so you can copy it into the Substitution view: +18005551212 8005551213 18005551214 (800)555-1215 800.555.1216 (800) 555-1217 800 555 12 18 stuff before +18005551221 stuff after stuff before 8005551222 stuff after stuff before 18005551223 stuff after stuff before (800)555-1224 stuff after stuff before 800.555.1225 stuff after stuff before (800) 555-1226 stuff after stuff before 800 555 12 27 stuff after 5551212

If you want to fetch the phone number including country code(+91) use this:
(?:(?:+91[\s-]?)|(?:0))?[6789]\d{9}

@Nisha_K21
What all formats you get the numbers in…generally the validation would be [6-9]{1}\d{9} as minimum is 10 number and as of now number start with 9,8,7,6
