Where Does Address Go When Mailing a Letter? 

You may wonder where your address goes when mailing a letter. Automated mail processing machines read addresses from the bottom up, looking for the city, state, ZIP code, and delivery address. If the address is missing, the mail piece will be delayed or misrouted. There are several things you can do to make sure the address is correct before mailing it. These include avoiding address errors and ensuring the address has all the relevant information.

Attention line abbreviation 

When you’re mailing a letter to an employer, you’ll want to include the date, company name, city, state, and ZIP code. Then, write the attention line. Then, add the person’s name, or, if you’re mailing to someone else, write “C/O Leon Smith.” 

The delivery address should run parallel to the longest side of the package. The full name of the recipient should be centered, followed by the street address, city, and zip code. Inside addresses may also be addressed with the attention line, but it appears two lines below the address. This will make the letter easy to read if the envelope becomes unreadable. The attention line abbreviation is a standardized acronym for the department, which the recipient must know. 

City line 

The City Line should be written in all upper case, and the destination postal office must understand it. The City Line is not a substitute for a country name. Regardless of the language of the recipient, it is important to follow postal rules and avoid mistakes. Using the incorrect style of the City Line could delay your mail delivery. For example, a post office in Krakow may handle the street address in an incorrect format. Luckily, there are several ways to make this part of your address legible. 

The Postal Service has strict guidelines for proper address formatting. You should avoid using lower case letters in your mailing address, placing the postal code above the city, and writing a colon in the attention line. You should also avoid using a comma after certain words, and writing the ZIP code on a separate line. In addition, postal codes should not be separated by a period, and they should be written in upper case. 

ZIP code 

If you’re wondering where your address goes when you mail a letter or package, here are a few tips to make it easier to find your destination. First, make sure that the state and ZIP code are in the same format. USPS does not read city lines, but some countries do, so be sure to put them where they belong. You can also look up your zip code on the USPS website to see if it’s in the right place. 

The first line of your address should include the recipient’s name. This should be followed by the city and state of the recipient. You can also include an “attention line” at the top. If you’re mailing internationally, be sure to write the country name in its entirety, using all capital letters. Additionally, if you’re mailing window envelopes, make sure that your address is visible through the window and that you have at least a quarter inch of clearance around the window. 


Incorrectly written directional can disrupt the delivery of your mail. If a post office misspells your address, the mail will go to a different destination. Directions for mailing addresses are often spelled out in the street address line. To avoid this, always double-check your directional information. Missing directional include N, S, E, NE, NW, SE, and SW. Make sure to spell out this directional on your envelope. 

In addition to the name of the person being addressed, you must include the mailing address. You may choose to use your name, or the name of the box or householder. However, it is highly preferred to include the full name of the addressee, especially on printed matter. In addition to the name, you must also include the city and state. For addresses outside the United States, you must also include the country or province. There are some other guidelines for writing a mailing address.
