Port Number to Airtel: MNP Process Step-by-Step

Want to switch to Airtel without changing your mobile number? Mobile Number Portability (MNP) allows you to keep your existing number and move to Airtel from any operator — Jio, Vi (Vodafone Idea), BSNL, or others. Here's the complete process.

What is Mobile Number Portability (MNP)?

MNP is a TRAI-mandated facility that lets you switch telecom operators while keeping your mobile number. You can port to Airtel from any operator in India. The process takes approximately 4 working days within the same telecom circle and up to 7 working days for inter-circle porting.

Eligibility for Porting to Airtel

• Your current number must be at least 90 days old with the existing operator
• No pending contractual obligations with your current operator
• There should be no pending request for change of ownership on the number
• Your number should not be under any legal/court order restriction

Documents Required

• Aadhaar card (original for biometric verification + photocopy)
• Passport-size photograph (1 copy)
• UPC (Unique Porting Code) — generated via SMS (see steps below)
• Porting form — filled at the Airtel store

Step-by-Step Porting Process

Step 1: Generate UPC (Unique Porting Code)

From your current mobile number, send the following SMS:

SMS: PORT <space> <your 10-digit mobile number> to 1900

Example: PORT 9876543210 → Send to 1900

You will receive a UPC (Unique Porting Code) via SMS within a few minutes. This code is valid for 4 days — complete the porting process within this time.

Step 2: Visit an Airtel Store

1. Find the nearest Airtel store at airtel.in
2. Carry the following:
   • Your UPC code (received via SMS)
   • Aadhaar card (original + photocopy)
   • Passport-size photo (1 copy)
   • Your current SIM card (keep it active)

Step 3: Fill the Porting Form

1. At the Airtel store, fill the Customer Acquisition Form (CAF) for porting
2. Provide your UPC code
3. Select your preferred Airtel plan (prepaid or postpaid)
4. Complete Aadhaar biometric verification (fingerprint)

Step 4: Receive Your Airtel SIM

1. You will receive a new Airtel SIM card at the store
2. Do not insert it yet — wait for the porting to complete
3. You'll receive an SMS from Airtel confirming the scheduled porting date and time

Step 5: Activation

1. On the scheduled porting date, your old SIM will stop working (usually between 10 PM and 6 AM)
2. Insert the new Airtel SIM into your phone
3. Restart your phone
4. Your number is now active on Airtel's network
5. You should receive a welcome SMS from Airtel

Porting Timeline

Port to Airtel eSIM

You can port your number directly to an Airtel eSIM instead of a physical SIM:

1. Generate UPC by sending PORT <your number> to 1900
2. Visit an Airtel store with Aadhaar and UPC
3. Request eSIM porting instead of physical SIM
4. After porting is processed, you'll receive an eSIM QR code via email
5. Scan the QR code on your eSIM-compatible phone:
   • iPhone: Settings → Cellular → Add eSIM → Use QR Code
   • Android: Settings → Network & Internet → SIMs → Add eSIM → Scan QR
6. Your number will activate on Airtel eSIM after the porting window

Note: Ensure your phone supports eSIM before requesting this option. See our Airtel eSIM guide for compatible devices.

Porting Charges

Reasons Porting May Be Rejected

Your porting request can be rejected if:

1. Number is less than 90 days old with current operator
2. UPC has expired (valid for only 4 days)
3. Outstanding dues on postpaid number with current operator
4. Incorrect documents or failed biometric verification
5. Active contractual obligation with current operator
6. Sub-judice number — number involved in legal proceedings

If rejected, you'll receive an SMS with the reason. Fix the issue and generate a new UPC to try again.

Important Tips

1. Clear postpaid dues first — if porting from a postpaid number, pay all outstanding bills before initiating the port.
2. Port during weekdays — requests made on weekends may take longer as working days are counted.
3. Keep your old SIM active — do not deactivate or remove your old SIM until porting is complete.
4. Inform your bank — update your mobile number with banks and services that use your number for OTPs, as there may be a brief gap during the switch.
5. Choose your plan before visiting — browse Airtel plans online to save time at the store.

Frequently Asked Questions

TRAI charges a nominal porting fee of ₹4, which is deducted from your Airtel balance after porting. The Airtel SIM card itself is free.

Can I port from Jio to Airtel?

Yes. The process is the same — send PORT <your Jio number> to 1900, get the UPC, and visit an Airtel store with Aadhaar and the UPC code.

What happens to my balance when I port?

Any remaining balance, validity, or active plans with your previous operator are forfeited. Airtel starts fresh — you'll need to recharge with an Airtel plan.

Yes. You can port from any operator's postpaid to Airtel prepaid (or postpaid). Clear all outstanding bills with your current operator first.

Can I port my number to Airtel online without visiting a store?

Currently, you need to visit an Airtel store for porting as Aadhaar biometric verification is mandatory. You can generate the UPC online, but the SIM collection and verification must be done in person.

What if my porting request is rejected?

You will receive an SMS with the rejection reason. Common reasons include expired UPC, outstanding dues, or the number being less than 90 days old. Fix the issue and generate a new UPC to re-apply.
