How to redact your utility bill for opening a bank account
Sending a utility bill to the bank? Here's exactly what to black out, what to keep, and how to redact it in under a minute — fully offline on your iPhone.
Black out the account number and any card or bank payment details on your utility bill, and keep your name visible so the bank can still verify you. Stamp the copy "For this account application only", then export a flattened PDF — all on your iPhone, nothing uploaded.
Why the bank asks for your utility bill
Banks must verify your identity and address (KYC) before opening an account. A utility bill is a common proof of address; it shows your name, service address, account number, and amount due.
The bank needs your identity and address confirmed; for remote sign-ups, send redacted copies and finish verification through the bank’s secure channel. The catch: the account number with your name and address supports account-takeover and address fraud. That's why you should hand over a redacted copy — see the full utility bill redaction guide or what to redact for opening a bank account.
What to redact on your utility bill
- Account number It can be used to social-engineer the utility and take over the account.
- Any card or bank payment details Printed payment info enables direct fraud.
- Usage and personal details you don't need to show Minimize to just what proves your address.
What to keep visible (so it's still accepted)
- Your name
- Your service address
- The issue date, to prove the bill is recent
The watermark to add
Stamp a purpose watermark so the copy can't be reused beyond opening a bank account:
Redact your utility bill in 4 steps
- Pick the photo. Open Cachera and choose the photo of your utility bill with the system picker — only that photo is read, never your whole library.
- Black out the sensitive fields. Drag a black block over the account number and any card or bank payment details. On export those pixels are destroyed — there's no hidden layer to recover underneath.
- Add a purpose watermark. Stamp "For this account application only" so the copy can't be reused beyond opening a bank account.
- Export and send. Lay it out on A4, export a PDF, and share it with the bank. Everything happened on your iPhone — nothing was uploaded.
Is this OK to do?
FAQ
Will the bank still accept a redacted utility bill?
Yes. Keep your name and your service address visible so they can confirm what they need, redact only the sensitive fields, and add a clear "For this account application only" watermark. A watermarked, partially-redacted copy is normal, accepted practice.
What should I never show on a utility bill?
Hide account number, any card or bank payment details, usage and personal details you don't need to show. The account number with your name and address supports account-takeover and address fraud.
Can the black bars be removed from the copy later?
No. Cachera flattens the redaction into the image on export — there is no hidden layer beneath the black blocks, so the covered text cannot be recovered from the PDF.
Should I send the original utility bill instead?
Upload only through the bank’s official secure portal — never by email. Redact anything the form does not explicitly require. A redacted copy with a purpose watermark is usually the safer choice.
