Porting Checklist: Xfinity Mobile
Xfinity Mobile is Comcast's MVNO running on the Verizon network, with its own port-out process inside the Xfinity app. Getting your Transfer PIN uses a one-time passcode (OTP) verification, and the PIN is sent via SMS to an active line on your account.
Xfinity Mobile does not charge a port-out fee. Any remaining device-financing balance becomes due on your next bill after the port.
What You Need from Xfinity Mobile
- Your Xfinity Mobile account number (not the Xfinity internet/cable account number — they're often different)
- A Transfer PIN
- The primary account holder's name exactly as on the Xfinity account
- The billing address on file
- Last 4 of the account holder's SSN (often required by the gaining carrier)
Step 1: Find Your Xfinity Mobile Account Number
- Xfinity app or xfinity.com/mobile: Sign in → Account Details
- Monthly Xfinity Mobile bill: Printed near the top
- Confirm it's the Mobile account number, not your Xfinity Internet account
Warning: Giving the Xfinity Internet account number instead of the Mobile account number is the most common rejection cause. If you have both services, double-check.
Step 2: Generate Your Transfer PIN
- Sign in to the Xfinity app or xfinity.com/mobile.
- Go to Devices.
- Select the device/line for the number you want to port.
- Scroll down and tap Transfer your number or cancel this line.
- Request a one-time passcode (OTP) for verification.
- Xfinity texts the PIN to an active line on your account (not necessarily the line you're porting).
Alternatively, call 1-888-936-4968 (Xfinity Mobile) or 1-800-XFINITY and ask an agent.
PIN Validity
24 hours. Initiate the port with Phound the same day you generate the PIN.
Tip: If you only have one line on the account, the OTP goes to that line — retrieve it before or during the port window. If you have multiple lines, check the other line for the code.
Step 3: Verify Account Details
- Full legal name of the primary account holder
- Billing address on file (recent moves can still be lagging — verify)
- Xfinity Mobile accounts are tied to the primary account holder only. If the bill-payer is a spouse or parent, the port must go out in their name, not the user of the phone line.
Warning: Name mismatches (wife vs. husband, missing middle initial) are a top rejection cause for Xfinity Mobile ports.
Step 4: Confirm Account is Active
- Line must be active — not suspended or canceled
- Account must be in good standing
- Numbers ported in or out within the last 30 days may be blocked from another port
Note: Xfinity Mobile requires an active Xfinity Internet, TV, or Home account to start mobile service, but porting out doesn't require those to still be active — the mobile account itself just needs to be in good standing.
Step 5: Submit Your Port Request in Phound
- Open Phound → Settings > Numbers > Port a Number.
- Enter the Xfinity Mobile number.
- Provide the Mobile account number, Transfer PIN, account holder name, and billing address.
- Submit.
Track in Check Your Porting Status.
Timeline
- Typical: 10 minutes to 72 hours (standard wireless port)
Common Rejection Reasons
- Used Xfinity Internet account number instead of the Mobile one
- OTP verification not completed — PIN never arrives
- Name mismatch with primary account holder
- Billing address mismatch after a recent move
- Port attempted within 30 days of a previous port
- Number lock still enabled (rare on Xfinity — disable via Line Settings in the app)
Special Gotchas
- Device financing — if your phone is on a payment plan, the remaining balance becomes due on the next Xfinity Mobile bill after the port. This is billing, not a port block.
- Xfinity Voice (home landline) is different. If you're porting a home-phone number, use the Xfinity Voice process, not the Mobile one.
