A KYC update letter is a short, signed request asking your bank to refresh the identity and address details it holds for your account, with supporting documents attached. Write it on plain paper (individuals) or letterhead (businesses), quote the account number, list exactly what has changed and attach self-attested copies of the proofs. Banks ask for periodic KYC updates and can restrict accounts when they lapse, which for an exporter can mean a foreign payment stuck in limbo.
Key takeaways
- Keep the letter short: who you are, which account, what is being updated, what is attached.
- Individuals usually attach identity and address proof plus PAN; businesses add entity documents and signatory authority.
- Ask your bank for its current KYC document list. Requirements vary by bank and account type.
- Submit through the channel your bank accepts and keep an acknowledged copy.
- Exporters should update KYC proactively: an incomplete KYC can delay inward remittances and trade documents.
When you need a KYC update letter
You might write one because:
- the bank has sent a periodic KYC update reminder;
- your address, name, contact details or constitution has changed;
- a new director, partner or authorised signatory needs to be recorded;
- the bank has restricted the account pending updated documents;
- you are about to start receiving export payments and want your profile complete first.
For exporters, the last point matters more than people expect. A foreign remittance that arrives in an account with pending KYC may be held while the bank completes its checks. Getting KYC current before your first export invoice is a cheap insurance policy. If a remittance is already held, our remittance release request letter is the companion format.
Typical documents: individuals vs businesses
Banks publish their own KYC lists, and they change. Use this as a starting point and confirm with your branch.
| Account holder | Usually requested | Sometimes requested |
|---|---|---|
| Individual | PAN, identity proof, current address proof, recent photograph | Updated contact details form, signature verification |
| Sole proprietorship | Proprietor's KYC, proof of business existence (for example GST registration) | Business address proof, IE code |
| Partnership firm | Partnership deed, firm PAN, KYC of partners and signatories | Registration certificate, authority letter |
| LLP | Incorporation certificate, LLP agreement, LLP PAN, KYC of designated partners | Resolution authorising signatories |
| Private limited company | Certificate of incorporation, MoA and AoA, company PAN, board resolution, KYC of directors and signatories | List of beneficial owners, registered office proof |
For a company or LLP, the bank may also want a fresh board resolution if signatories have changed. Our board resolution format can be adapted.

A worked example
Sunward Localisation LLP, a Pune translation firm, received a KYC reminder from its bank in September 2026, just as it was expecting EUR 6,800 from a client in Lyon. One designated partner had retired in July and a new one had joined.
The firm's manager prepared a business KYC letter on letterhead, attached the updated LLP agreement, a resolution recording the change in designated partners, PAN and KYC of the new partner, and submitted it at the branch. She asked for the acknowledgement on a copy. When the euro payment arrived two weeks later, the account was current and the credit went through normally. Had the update waited, the bank might have held the payment while the signatory records were out of date.
Submitting the letter
- Channel: branch, net banking upload or another method your bank accepts. Ask which applies to your account.
- Self-attest copies: sign each copy and, for businesses, have the authorised signatory sign.
- Originals: carry them if the branch needs to verify.
- Acknowledgement: ask for a stamped copy or reference number and file it.
- Follow up: if you hear nothing in a reasonable time, ask the branch to confirm the update is complete.

Frequently asked questions
What should a KYC update letter to a bank contain?
Your name or business name, account number, a clear statement of what is being updated, a list of enclosed documents and your signature. Businesses should use letterhead and sign as an authorised signatory.
Which documents do I attach for a business KYC update?
Typically entity documents (such as incorporation certificate, partnership deed or LLP agreement), the entity's PAN, signatory authority and KYC of signatories. Ask your bank for its current list, as requirements vary.
Can incomplete KYC hold my foreign remittance?
It can. Banks may hold or restrict transactions while KYC is pending, including inward remittances. Exporters should keep KYC current, especially before expected payments.
Do I need to submit originals with the KYC letter?
Usually you submit self-attested copies and the bank may ask to see originals for verification. Check with your branch before visiting.
