# Is there a way to check phone number format?

If I try the phone format in the field, it can provide a phone format.However, even I type in character, the system still accept it. If I use the number format, it can restrict users only to type number. However, the outlook of data will become a number format with this sign (","). How can I solve this problem? Thank you.

Hi Alex,
Yes, there is a way to check phone number format.

The below Validation Formula checks the phone number format as 999-999-9999.
1) Create a Validation rule for the PHONE Field.(Validates the Format of Data before saving)
2) Under Error Condition Formula add the syntax : NOT(REGEX(Phone, "[0-9]{3}-[0-9]{3}-[0-9]{4}"))
3) Give a Error message to display.
4) Save.

or

The below Validation Formula that the Phone number is in (999) 999-9999 format.
This works by using the REGEX function to check that the number has ten digits in the (999) 999-9999 format.
Formula: NOT(REGEX(Phone, "\\D*?(\\d\\D*?){10}"))
Error Message:US phone numbers should be in this format: (999) 999-9999.

Let me know if it helps you,

Best Regards,

@Onesh Reddy Sorry for forgetting to tell you that US phone format is not suitable for me. I want a 8-digit number checking. And I need to check them in the apex code level, but not the field setting level.
```if(artist.PhoneNumber__c != null){
Pattern emailPattern = Pattern.compile('d\d?\d?\d?\d?\d?\d?\d?');
