Hi Narmada , Following rule might help you in validating mobile numbers of 4 different formats. Additional formats can also be added, if needed. 
 
if( 
 isnull( 
 ri!mobileNumber 
 ), 
 null, 
 or( 
 regexmatch( 
 "^(\+\d{1,3}[- ]?)?\d{10}$", 
 ri!mobileNumber 
 ), 
 regexmatch( 
 "^($[0-9]{3}$ |[0-9]{3}-)[0-9]{3}-[0-9]{4}$", 
 ri!mobileNumber 
 ), 
 regexmatch( 
 "^$[0-9]{3}$[0-9]{3}-[0-9]{4}$", 
 ri!mobileNumber 
 ), 
 regexmatch( 
 "^\+[0-9]{10,20}$", 
 ri!mobileNumber 
 ) 
 ), 
 null, 
 { 
 "Invalid mobile number.", 
 "Valid formats (555)555-5555 or 555-555-5555 or 1234567890 or +1234567890" 
 } 
) 
 
Please note that, you need to install this plugin to use this function community.appian.com/.../regular-expression-functions

You can try below code: 
load( 
 local!number:"1234567890", 
 like(local!number,"[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]") 
) 
 
Thanks

Hi, 
Try to use a!integerField(). This will throw a validation message if any non-numerical characters are input. Then you can simply check - variable > 10 to show validation message 
 
If you want to include hyphen or any phone number format then use regexmatch function. You can get the pattern from Google. 
 
If you have to use a text field, you can also use cleanwith or stripwith function to perform validations.

Hi Narmada, 
You can create a rule and write following content inside it:

if( 
 or(fn!isnull(ri!data_anyType),ri!data_anyType=""), 
 true(), 
 length(ri!data_anyType) = 0 
)

Where data_anyType is a rule input of type anytype 
 
Hope this will help you.

Hi Narmada please make sure that, you are performing null check before evaluating length() because length() throws an error if the value is null. 
 
So you can do it in following way: 
 
if( 
rule!APN_isBlank(local!phoneNumber), 
{}, 
if( 
length(local!PhoneNumber) > 10,"Maximum 10 digits are allowed",{} 
) 
) 
 
Hope this will help you

Also, just a quick thought, if your application will be used across indian origin only, then this validation will work fine for you. 
 
But if your application will be used across multiple countries, then this validation won't work for you, because number of digits for a valid mobile number varies from country to country. 
 
Hence, if it's the case,. Your rule must be dynamic and configurable.
