Here’s a quick guide to writing the address for two common types of US postal address: residential and PO Box.

Residential addresses

The format for US residential addresses is very similar to UK addresses, but there are a few important differences to note:

UK address format US address format
Mr James Smith
Flat 7
118 Blackhorse Grove
London
W6 7HB
UK
Ms Alice Smith
Apartment 1c
213 Derrick Street
Boston, MA 02130
USA
 

1. You will need to write the name of the state in which the city, town or village you are sending to is located. Use the two-letter state abbreviation, such as MA for Massachusetts as shown above.

2. You will also need to add a five-digit ZIP code (postal code). There may be an extended code (ZIP+4) where a hyphen and a further four digits (“-1234”) are added to the five-digit code, but this is not usually required.

3. Write the city/town/village name, the state and the ZIP code on the same line, as shown above.

PO Boxes

The format for sending to a PO Box is very similar.

UK address format US address format
Mr James Smith
Transglobal Express
PO Box 1234
Bromborough
CH62 3NX
UK
Ms T. Globelle
Paragon Productions
PO Box 5404
Los Angeles, CA 90210
USA
 

When sending a parcel or letter to a PO Box in the USA:

1. Write the addressee’s name and company name (if applicable) on the first couple of lines. On the next line, write the PO Box number.

2. Underneath the PO Box number, write the city, state and ZIP code.

3. Once again, an extended ZIP+4 code is not required, but for PO Boxes it will usually repeat all or part of your PO Box number.

4. In general, you do not need to include a street address for PO Boxes. However, if you do, put it above the PO Box number, as the US Postal Service sorts from the last lines of your address and the PO Box number is more important!

Please note that many carriers have PO Box restrictions, so please check before trying to send a parcel or letter to a PO Box in the US.

You can send to a private mailbox using the same address format as above, but you must put “PMB” or “#” instead of “PO Box”. If this line of the address also includes a secondary number such as a rural route box or suite number, you must use “PMB” and not “#” to avoid confusion.
