WhatsApp KYC Documents Risk is becoming a growing concern as many people continue to share PAN cards, Aadhaar cards and bank statements through personal WhatsApp numbers for verification.
While the request may appear genuine, cybersecurity experts warn that such documents can remain stored on personal devices and cloud backups long after they are shared.
Banks, loan agents, property brokers and hotels often ask customers to submit KYC documents. However, sending these files over WhatsApp can reduce your control over how your personal information is stored and used.
WhatsApp KYC Documents Risk
According to Abhinav Parashar, Co-founder and CEO of digital trust platform Digio, people often believe they are sharing documents with an organisation, but the files are actually sent to an individual’s personal device.
Even if there is no misuse, the documents may remain stored on phones, laptops or cloud storage for years. If those devices or accounts are later compromised, sensitive personal information could be exposed.
The expert also warned that collecting KYC documents through personal phone numbers instead of official company systems creates additional copies of the same document and takes the data outside the organisation’s normal cybersecurity controls.
Why official verification is safer
Parashar recommends that businesses use official digital forms or secure verification systems instead of asking customers to send documents over WhatsApp.
He said organisations can verify identity through platforms such as DigiLocker or UIDAI’s Offline Verification Seeking Entity (OVSE) framework. These methods allow identity verification through secure systems rather than personal messaging apps.
What the DPDP framework means
India’s Digital Personal Data Protection (DPDP) framework places greater emphasis on responsible collection and use of personal data.
According to the expert, official business portals provide a clearer record of who is collecting personal information and for what purpose.
In contrast, once a document is downloaded, forwarded or backed up from a personal messaging app, it becomes much harder to track where copies exist.
What you should do before sharing documents
Experts advise asking for an official company portal or secure upload link whenever you are asked to submit PAN, Aadhaar or bank statements.
If sending documents through WhatsApp cannot be avoided, Parashar recommends using a password-protected file and sharing the password separately.
Since PAN cards, Aadhaar cards and bank statements contain highly sensitive personal and financial information, taking these precautions can help reduce the risk of unauthorised access.
