Hello @Rajyalakshmi, navigate to Service Catalog > Catalog Variables > Variable Validation Regex and define following as regular expression. Then, attach the same to variable in the item

^0\d{2}$

please use this onChange catalog client script on your variable

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue === '') {
        return;
    }

    var variableName = 'your_variable_name';

    var regex = /^0\d{2}$/;
    if (!regex.test(newValue)) {
        g_form.showFieldMsg(variableName, 'Value must start with 0 and be exactly 3 digits', 'error');
        g_form.clearValue(variableName);
    } else {
        g_form.hideFieldMsg(variableName, true);
    }
}
