Understanding and Formatting a "Letter With Thru"
A "letter with thru" signifies a situation where one person is sending a letter via another person. It’s essentially routing the letter through an intermediary, and this fact is noted on the letter itself for clarity. Proper formatting is important for transparency and record-keeping. Let’s break down the components and layout.
Key Elements of a "Letter With Thru"
This type of letter requires specific notations to indicate the routing process. Failure to include these can lead to confusion about the letter’s origin and intended recipient.
- The Sender’s Information: This is the person actually sending the letter. Their full name and address should be included at the top.
- The "Thru" Designation: This clearly indicates who the letter is being routed through.
- The Intermediary’s Information: This is the person facilitating the delivery. Their full name and address must be stated directly after the "Thru" designation.
- The Intended Recipient’s Information: This is the ultimate receiver of the letter. Their full name and address should be placed after the intermediary’s information.
- The Body of the Letter: Contains the actual message being conveyed.
- Closing and Signature: Standard closing remarks followed by the sender’s signature and typed name.
Formatting the Letterhead & Addresses
The placement of the sender, intermediary ("Thru"), and recipient’s addresses is crucial.
Sender’s Address
This goes at the very top, typically aligned to the left or centered.
"Thru" Designation
Immediately following the sender’s address comes the "Thru" designation. It is written on a separate line, either left-aligned or indented slightly. You can use "Thru:", "Via:", or "C/O:" (Care Of:) – all are acceptable.
Intermediary’s Address
This follows directly after the "Thru" designation. Their full name and address should be placed on subsequent lines, properly formatted as a standard address.
Recipient’s Address
The recipient’s address is placed after the intermediary’s address. This follows the same format as a standard address and is vital for the correct delivery path.
Address Placement Example
Here’s an example of how the address section should look:
[Sender's Full Name]
[Sender's Street Address]
[Sender's City, State, Zip Code]
Thru:
[Intermediary's Full Name]
[Intermediary's Street Address]
[Intermediary's City, State, Zip Code]
[Recipient's Full Name]
[Recipient's Street Address]
[Recipient's City, State, Zip Code]
Salutation & Body
The salutation should address the intended recipient, not the intermediary.
Salutation Example
"Dear [Recipient’s Name],"
Body Content
The body of the letter contains the message. It should be clear and concise. While this is still a formal letter, the tone might slightly differ based on your relationship with the intended recipient, or the purpose of the letter.
Formatting the Body
Standard business letter formatting applies:
- Single-spaced within paragraphs.
- Double-spaced between paragraphs.
Closing and Signature
Use a professional closing. "Sincerely," "Respectfully," or "Best regards," are all appropriate.
Signature Block
- Leave several lines for your signature.
- Type your full name below the signature line. This should be the same name used in the sender’s address at the top.

Letter With Thru FAQs
Here are some frequently asked questions about using the "letter with thru" format and our free template to ensure clarity and efficiency in your professional correspondence.
What does "thru" mean in a letter?
"Thru" in a letter indicates who the letter is being routed through or who needs to be aware of its contents beyond the direct recipient. It’s essentially a courtesy notification. This shows others have seen or need to know the context of the letter, particularly when dealing with hierarchical structures.
When should I use "thru" in my business letter?
Use "thru" when your letter needs to be brought to the attention of someone before it reaches the ultimate recipient, or when a person needs to be aware of its contents but is not the direct action-taker. It’s most common when reporting upwards through a management chain.
How is "thru" different from "cc" in a letter?
"Cc" (carbon copy) means the person listed is receiving a copy of the letter for informational purposes. "Thru" implies a more direct path or required approval/awareness within a specific hierarchy. A "letter with thru" indicates a routing process, while "cc" implies a passive copy.
Where does "Thru" go in the letter format?
The "Thru" line typically appears below the salutation and before the body of the letter. It’s clearly distinguished from the main recipient information. This placement ensures the routing information is immediately visible.
