How to Write, Label, or Address a Business Envelope or Letter

    If you’re working in an office or need to send a letter to a company, you’re probably wondering how you can write, label, or address a business envelope, folder, or letter.

    These are the big yellow envelopes that typically are mailed to / from businesses and it’s a little different from sending a normal letter.

    We’ve got you covered so your letter ends up in the right location and gets to the person you intended.


    Guidelines and image example

    • Make sure you are writing only on the front of the envelope. The back of the envelope is where it opens to insert the letter.
    • It is recommended to use a pen or print directly on to the envelope as pencil can be erased. Pencil can be used, but beware.envelope

    Step 1 – Add the Return Address

    The return address is needed in case the letter could not be delivered. It will be sent back to you if the mailing address is incorrect. Add this at the top-left of the envelope Include the following in the return address in this order:

    • Your name
    • First line of your address – this is the street address or PO box
    • Second line of your address – this is the city, state, and zip/postal code


    Step 2- Add the mailing address

    The mailing address is the location or business you want to send the letter to. Add this in the middle of the envelope. Include the following in the mailing address in this order:

    • Name of the contact or business you are mailing (if you do not know the contact, you can use ‘To Whom it May Concern’
    • (Optional for business mailings) Attention line – this is if you need to have the letter directed to a specific contact or department. Format with ATTN: or c/o
    • First line of the address you are sending to – this is the street address or PO box
    • Second line of the address you are sending to – this is the city, state, and zip/postal code
    • If you are sending to another country, add the country here. Do not include if the letter is not leaving the country (such as mailing from the USA to the USA).


    Step 3 – Stamp / postage

    Add the correct stamp (also known as postage) to the top right of the envelope.

    • The correct postage is determined by how much your letter weighs. This may be more than the standard price as these envelopes can weigh more.
    • Check with the post office if you are concerned about the correct postage
    • Do not write over the stamp as it will become invalid.
