Limit the length of phone number

1

I want to limit phone number with only 10 digit. How it is done in regex part?

To limit a phone number to exactly 10 digits using regular expressions (regex), you can use the following pattern:

^\d{10}$

Explanation of the pattern:

  • ^: Asserts the start of the string.
  • \d: Matches any digit (0-9).
  • {10}: Specifies that exactly 10 occurrences of the preceding \d should be matched.
  • $: Asserts the end of the string.

Combined, the pattern ^\d{10}$ ensures that the entire string contains exactly 10 digits and nothing else.

Unfortunately, this isn’t feasible, as displaying the regex format is essential. Otherwise, users would be uncertain about the required pattern to match in case an error occurs.
