hi folks, if you want to validation phone number annotation in MVC.

use this code which is shown below:

```
        <li class="cell last" style="width: 60%;">Phone Number:</li>         <li class="cell last" style="width: 60%;">
            @Html.TextBoxFor(model => model.PhoneNumber, new { @class = "textbox" }) @Html.ValidationMessageFor(model => model.PhoneNumber)
        </li>
```

please check your Models and Views properly:

```
@Html.LabelFor(model => model.PhoneNumber)
@Html.EditorFor(model => model.PhoneNumber)
@Html.ValidationMessageFor(model => model.PhoneNumber)
```

this [Data](https://www.mindstick.com/articles/13050/salesforce-aiming-to-dominate-predictive-analytics-with-data-science) Annotation alone is enough if you need regex for validation. as you want to using data annotation so its helpful for you which is shown below:

Syntax:

```
[RegularExpression(@"^([0]|\+91[\-\s]?)?[789]\d{9}$", ErrorMessage = "Your entered Mobile No is not valid.")]
```

Code:

```
public class PersonModel
{
    [Display(Name = "Mobile Number:")]
    [Required(ErrorMessage = "Mobile Number is required.")]
    [RegularExpression(@"^([0-9]{10})$", ErrorMessage = "Your entered no is Invalid.")]
    public string MobileNumber { get; set; }
}
```

I hope, It will be helpful for you.

Happy Coding :)
