Part of writing your apartment address correctly is knowing which word to use for your unit and how to abbreviate it. Some of the most common are apartments, suites, units, and penthouses, and here’s how to shorten them. 
  • Room/Rm: Used to denote a room marked off in an apartment or a room in a hotel or office. 
  • Suite/Ste: Though this is more common among office buildings, it occasionally happens in apartments or “hard lofts.”
  • Apartment/Apt: This is the classic go-to. If you don’t know which abbreviation to use, use this one. 
  • Building/Bldg: This denotes a building. 
  • Unit/Unit: Some buildings call their apartments “units.”
  • Mailbox/Box: If you are assigned a mailbox or use a mailbox number for your mail, you might use the mailbox number instead. 
  • Penthouse/PH: Penthouse typically refers to the top floor(s). 

Be Clear and Concise when Writing an Apartment Address

When writing an apartment address, ensure you are clear and concise when providing the necessary information. Therefore, don’t abbreviate street names or misspell words. This could lead to your package misdelivered or, worse yet, never arriving at its intended destination.

If you are unsure how a particular word should be spelled, consult a dictionary for the correct spelling before writing out the address on your package. Proper punctuation is also essential since it can help ensure delivery service accuracy.

What Happens if You Don’t Put the Apartment Number on the Envelope?

In many cases, not entering your apartment number will result in your package or envelope returned to the sender. Depending on what you want to receive, this cannot be good. For this purpose, put a return address on the back of the envelope.

Sometimes, this might result in a package being received by a doorman or a community mailbox. However, this only happens in a handful of cases, and it’s never guaranteed. To prevent any mishaps or confusion, always write the complete address.

Double-Check Your Work after Writing an Apartment Address

The last step is double-checking your work before sending off your package.

Ensure all the information provided is correct, including special instructions such as “drop off only” or “do not deliver after 5 p.m.” This way, you avoid confusion once your package gets picked up by its intended recipient. Additionally, if possible, it would also be helpful to include contact details outside of your box so that someone can easily reach out for assistance if there are any delivery issues.

Good luck!
