@IsPhoneNumber fails for valid Saudi Arabia (SA) numbers starting with +96657

[Mohamed-Sa2024]

Describe the bug The @IsPhoneNumber('SA') (or with no region specified) decorator fails to validate valid Saudi Arabian mobile numbers that use the 57 prefix (e.g., +96657XXXXXXX). These numbers are primarily assigned to Virgin Mobile or STC in Saudi Arabia and are fully operational.

To Reproduce Steps to reproduce the behavior:

Create a DTO with the @IsPhoneNumber() decorator.

Pass a phone number starting with +96657 (e.g., +966579386956).

Validation fails with: isPhoneNumber: phone must be a valid phone number.

Code Example

TypeScript

import { IsPhoneNumber } from 'class-validator';

export class CreateOtpDto {
  @IsPhoneNumber('SA') // or @IsPhoneNumber()
  phone: string;
}

// Data: { "phone": "+966579386956" }

Expected behavior The validator should return true for valid Saudi numbers starting with 57.

Actual behavior (Error Stack Trace)

JSON

{
  "response": {
    "message": [
      {
        "target": { "phone": "+966579386956" },
        "value": "+966579386956",
        "property": "phone",
        "children": [],
        "constraints": { "isPhoneNumber": "phone must be a valid phone number" }
      }
    ],
    "error": "Bad Request",
    "statusCode": 400
  }
}

Additional context This is likely due to an outdated version of google-libphonenumber or libphonenumber-js in the project dependencies, as the 057 range was added to the Saudi numbering plan more recently than other prefixes like 050, 055, etc.
