Frequently Asked Questions (FAQs)
What is a KYC API?
A KYC API is an endpoint your application calls to verify a customer's identity document against the record that issued it, in real time, and get the result back as JSON. FastKYC's KYC APIs cover PAN, Aadhaar, driving licence, voter ID, passport, bank accounts, GST and more, through one API key.
What services does FastKYC provide?
We offer APIs for identity verification, bank account verification, GST and business (KYB) verification, employment and UAN verification, document OCR, Aadhaar masking and fraud checks, plus WhatsApp KYC and SMS APIs, and a consent-first background verification product for employers.
Is API-based KYC legal and safe in India?
Yes. API-based KYC is how Indian banks, NBFCs, fintechs and marketplaces verify customers at scale. FastKYC returns data from official government and financial records; you collect the customer's consent, apply your regulator's KYC rules and keep the purpose limited, which the DPDP Act expects. Data is encrypted and API access can be locked to your private network.
What is the difference between KYC, eKYC and CKYC?
KYC is the process of verifying who a customer is. eKYC is KYC done electronically, such as verifying PAN against the income-tax record or an Aadhaar offline XML online instead of on paper. CKYC is the Central KYC registry: once a customer has a CKYC record, a regulated entity can search and, with the customer's OTP consent, download it instead of collecting documents again. FastKYC offers APIs for all three.
How fast is the verification process?
All checks are done in real time, giving instant results within seconds.
Which IDs can be verified?
You can verify PAN, Aadhaar (masking & link check), Passport, Driving License, Voter ID, and GSTIN through our APIs.
How much does KYC verification cost?
Pricing is per verification and depends on your monthly volume and the checks you use; a PAN name lookup and a credit report are priced differently. Share your expected monthly volume and the team sends a rate card.
How do you verify a bank account without transferring money?
With the pennyless bank verification API, which validates an Indian bank account and returns the account holder name from real-time banking network data, with no deposit. Penny drop, which deposits one rupee and reads the name back from the bank, remains available when you want that proof, and the hybrid API routes between the two automatically.
Do you connect with official sources?
Yes. We fetch and verify data directly from government databases and trusted financial systems.
Is my customer data secure?
Absolutely. We use end-to-end encryption and follow strict compliance standards to protect sensitive data.
Do you use AI for verification?
No. We don’t use AI. All verification is done using authorized government and financial data sources only.
Can biometric checks be integrated?
Yes. Our APIs support Face Match and Liveliness Detection for secure and fraud-free verification.
Who can integrate FastKYC APIs?
Our APIs are built for banks, NBFCs, fintechs, insurers, marketplaces, and enterprises that need secure, reliable onboarding.
