String card_no=driver.findElement(By.xpath("//td[@aria-describedby='CustomerGrid_cardNo']")).getText();
             System.out.println(card_no);

            if(card_no.length()==0){
                System.out.println("Customer is not register and proceeding for registration");
                driver.findElement(By.id("cardNo")).sendKeys("39409297");
                driver.findElement(By.id("Btn")).click();
                Thread.sleep(2500);             

            }else{
                System.out.println("Customer Mobile No is already registered -"+card_no);
            }

<td aria-describedby="CustomerGrid_cardNo" title="7348054" style="text-align:center;" role="gridcell">7348054</td>

Solution

You can try like below,

int card_no=driver.findElements(By.xpath("//td[@aria-describedby='CustomerGrid_cardNo']")).size();
             System.out.println(card_no);

            if(card_no==0){
                System.out.println("Customer is not register and proceeding for registration");
                driver.findElement(By.id("cardNo")).sendKeys("39409297");
                driver.findElement(By.id("Btn")).click();
                Thread.sleep(2500);             

            }else{
                System.out.println("Customer Mobile No is already registered -"+card_no);
            }
