Letterhead Format: Designing a Business Letterhead That Looks Official

An official-looking letterhead shows your full legal name, logo, registered address and contact details at the top, with statutory identifiers such as GSTIN and, for companies and LLPs, the registration number placed neatly in the header or footer. The test is simple: a bank officer or foreign client should be able to identify exactly which legal entity sent the letter without reading the body. Clean layout, one or two fonts and generous margins do the rest.

Key takeaways

• Lead with the exact legal name as registered, not just a brand name.
• Include registered address, phone, email and website; add GSTIN and, for companies and LLPs, CIN or LLPIN.
• Keep the header compact so the letter body has room; put secondary details in the footer.
• Use a high-resolution logo, one or two fonts and a restrained colour palette.
• Ask your company secretary or CA what your entity type must show on business letters.

Why letterheads still matter for exporters

Service exporters send more formal letters than they expect: EDF covering letters, FIRC requests, purpose code corrections, realisation extension requests, AD code requests and KYC updates. Banks often ask for these on letterhead because it ties the request to the account holder.

Foreign clients see your letterhead too, on engagement letters, quotations and confirmations. A tidy one signals an established business.

What to put on the letterhead

Company law sets out certain particulars companies must show on business letters and documents. Rather than quote it here, ask your company secretary or CA what applies to your entity. LLPs and partnership firms have their own conventions.

Layout and typography that look professional

Header height. Keep it to roughly the top 15–20% of the page. Oversized headers squeeze the content and look dated.

Alignment. Left-aligned or centred headers both work. Align the header with the body text margin so the page feels deliberate.

Fonts. Use one typeface for the name and another, or the same, for details. Readable sans-serif fonts look modern; classic serifs feel traditional. Avoid decorative scripts for anything you need people to read.

Colour. One brand colour plus black or dark grey is enough. Remember many letters are printed in black and white or scanned; check that the logo still reads in greyscale.

Footer. Put statutory identifiers and secondary addresses here in a smaller size, separated by thin dividers or middle dots.

Margins. Leave at least 2 cm on the sides so printed letters do not lose edges and scanned copies stay legible.

Two worked examples

Company letterhead. Harbourline Software Private Limited, an IT exporter in Kochi, uses:

• header: logo on the left; "Harbourline Software Private Limited" in bold; "Registered Office: [address], Kochi, Kerala" in smaller text below;
• right side of header: phone, email;
• footer: "CIN: [number] · GSTIN: [number] · www.[domain]".

When Harbourline writes to its bank asking for a FIRC, the officer immediately sees the legal entity, matching the account name.

Proprietorship letterhead. Asha Menon runs "Pebble & Pine Illustration" as a proprietorship. Her letterhead shows "Pebble & Pine Illustration" prominently, "Proprietor: Asha Menon" below it, the business address, phone and email, and GSTIN in the footer. Showing the proprietor's name helps the bank, since the account is in her name trading as Pebble & Pine.

Mistakes that look amateur

1. Brand name only. If your account is in the name of "Harbourline Software Private Limited", a letterhead saying "Harbourline" alone invites questions.
2. Outdated address. After moving office, update the letterhead and inform the bank using an address change letter.
3. Low-resolution logo. Pixelated logos look careless in print.
4. Too many colours or fonts. Restraint looks confident.
5. Personal email addresses. Use a domain address if you have one.
6. Overcrowded footer. Include what is needed, not everything you know.

Using the letterhead for bank letters

Once your letterhead is ready, our bank letters library lets you generate common requests, such as FIRC requests, EDF covering letters and KYC updates, and place them on your letterhead. For guidance on tone and structure, see how to write a formal letter to a bank manager.

Frequently asked questions

What should a business letterhead include in India?

At minimum, your full legal name, logo if you have one, registered address, phone and email. GST-registered businesses commonly add GSTIN, and companies and LLPs usually show their CIN or LLPIN; your company secretary or CA can confirm what your entity must display.

Is a letterhead mandatory for letters to the bank?

Not always, but banks often expect business requests on letterhead because it identifies the account holder clearly. For individual accounts, a plain signed letter is usually fine.

Should a sole proprietor show their own name on the letterhead?

It helps. Showing "Proprietor: [Name]" alongside the trade name links the business to the account holder, which makes bank correspondence smoother since the account is in the proprietor's name.

What is the best size and margin for a letterhead?

A4 is the standard in India. Keep the header to about the top 15–20% of the page and leave at least 2 cm side margins so printed and scanned letters remain clean and legible.

Can I use the same letterhead for invoices?

You can use the same header design for consistency, but invoices have their own mandatory fields under GST. Use a proper invoice template that includes those fields rather than simply typing an invoice on letterhead.

Bottom line

A good letterhead is mostly about accuracy and restraint: the right legal details, a clean layout and nothing extra. Create yours in minutes with the free letterhead tool and use it for every bank and client letter.
