Are the 4 digits after a zip code unique to one specific address

This answer was rated:

Are the 4 digits after a zip code unique to one specific address in the same way a certain fingerprint is unique to a certain person? Thank you.

Hello there and welcome to JustAnswer! My name is XXXXX XXXXX I am very happy to help you with your question.

Khristopher N. Sines AACJ :

The four additional digits are called an "add-on code," and are used to denote a smaller area inside the main zip code. They are used when a small area receives a large volume of mail, to make sorting and delivery more efficient.

Customer:

So they are not unique to a specific address then; 2 or more different addresses can have the same add-on code?

Customer: XXXXXnumbers for example?
Khristopher N. Sines AACJ :

They are not unique to two different street addresses!

Customer:

In other words, 2 or more different addresses can have the same add-on code, correct?

Khristopher N. Sines AACJ :

Yes!

Khristopher N. Sines AACJ :

If they are in the same area, the zip code add on can be the same.

Customer:

So the add-on code is then unique to a specific AREA then, correct?

Customer:

A specific area in a city or town.

Khristopher N. Sines AACJ :

If a person sends a letter to someone and the street address, city, state, and zip code are all correct, but only the add-on code is wrong, will the letter still be delivered? Thank you.

Using the correct add-on ZIP Code helps to direct your mail more efficiently and accurately. Chances are the mail will still be delivered because the name, city, state, and zip. The add-on helps with sorting and delivery. The mail will reach it's destination. Just sooner with correct information!
