The CAF Number (Customer Application Form Number) in the telecom sector is a unique identification number assigned to every new mobile connection request in India. When you apply for a new SIM card (Prepaid or Postpaid) or port your number to a new operator, you are required to fill out a Customer Application Form (CAF), either physically or digitally via e-KYC.
This form acts as a contract between you and the Telecom Service Provider (TSP). The CAF Number is the reference ID for this specific contract. In the age of digital Aadhaar verification, while physical forms are less common, the digital record created still generates a CAF Number. It is critical for regulatory compliance with the Department of Telecommunications (DoT).
What Does CAF Number Telecom Mean
CAF stands for Customer Application Form. The number associated with it tracks your identity proofs (POI) and address proofs (POA) linked to a specific mobile number.
For example, if you buy a Jio or Airtel SIM, your biometric or Aadhaar data is captured. This data is packaged into a digital application labeled with a CAF Number. This number allows the telecom operator and government audit agencies (like TERM Cells) to verify that the SIM was issued to a real, verified person.
Why CAF Number is Important
The CAF Number is vital for safety and service management:
- Verification Audit: The DoT randomly checks CAF numbers to ensure telecom operators are not issuing SIMs to fake identities.
- SIM Activation: The activation process relies on the approval of the CAF. If the CAF is rejected due to blurry documents, the SIM will not activate.
- Disconnection: If you want to permanently disconnect a number, referencing the CAF details ensures the correct account is closed.
- TAFCOP Portal: On the TAFCOP (Telecom Analytics for Fraud Management) portal, your active connections are essentially a list of valid CAFs linked to your Aadhaar.
Where is CAF Number Used
You encounter this number in:
- New SIM Purchase Receipts: Printed on the acknowledgment slip.
- Tele-verification: Sometimes mentioned during the address verification call.
- Operator Database: Used by customer care to pull up your original submitted documents.
How to Find or Check CAF Number
As a consumer, you rarely need to memorize this, but you can find it if needed:
- Check the Receipt: When you buy a SIM, the store gives a receipt. The CAF Number is usually at the top.
- MyJio / Airtel Thanks Apps: In the profile or settings section under “Registered Details,” you might see a Reference or Application Number, which is the CAF ID.
- Customer Care: You can call 198 and ask the agent for your CAF number for verification purposes.
Example of CAF Number
It is typically a long alphanumeric string, varying by operator:
CAF No: KA01-987654321
Or simply a numeric string like Application ID: 1000556677.
Common Problems or Errors
- CAF Rejected: This means your photo or ID proof was not clear. You must visit the store to re-do the KYC.
- Multiple CAFs: If you have more than 9 SIMs (the limit in India), new CAFs will be rejected automatically. You must disconnect old numbers via TAFCOP.
Important Things to Remember
- Never sign a blank CAF (physical form).
- Ensure the retailer uploads your photo, not someone else’s, to the digital CAF.
- Check SIM Activation Reference for the next step.
- Understand CEIR Request ID if your phone is lost.
- Get Lost Report Number for lost SIMs.

Frequently Asked Questions
1. Is CAF Number different from Mobile Number?
Yes. The Mobile Number is the 10-digit number you use to call. The CAF Number is the administrative ID for the application form you submitted to get that mobile number.
2. Can I view my CAF form online?
Generally, operators do not allow you to download the full CAF form online for privacy reasons. However, you can verify the details (Name, Address) linked to it via the operator’s official app.
3. What happens if my CAF is rejected?
If your CAF is rejected by the auditor, your SIM card will be deactivated immediately, even if it was working for a few days. You will need to submit fresh KYC documents.
4. How many CAFs can exist under my name?
According to DoT regulations, one citizen can have up to 9 mobile connections (CAFs) in their name across all operators (6 in J&K, Northeast, and Assam).
5. Where can I check all CAFs linked to my Aadhaar?
You can visit the TAFCOP Portal, enter your mobile number, and see all connections active under your name.
