A letter with insufficient postage or a wrong address will not be delivered. Neither will one with an incorrect ZIP code. Follow the basic rules when you address and stamp a letter. Write the address with a non-drip ink pen to ensure ink does not run if it is exposed to inclement weather. Always include your return address in case the U.S. Postal Service needs to return an undeliverable letter to you. Add the proper ZIP code to the letter to ensure delivery.
