To transfer number from AT&T to Straight Talk, you must keep your AT&T service active throughout the process and never cancel it beforehand. You will need your AT&T account number, a Number Transfer PIN (NTP), and the exact billing address on file to authorize the port request during activation on Straight Talk.
Before you transfer your number from AT&T to Straight Talk
The golden rule is simple: do not cancel your AT&T service before the number transfer to Straight Talk is fully complete. Canceling early will lock your number and prevent the transfer. Your AT&T phone number must be active with AT&T at the time of the transfer request, and your account must be in good standing with no suspensions, past-due balances, or disconnections.
To check eligibility, confirm that your number is portable and that you have no unresolved contractual obligations. You can confirm number portability by contacting AT&T's customer service or checking your account details online. Gather the following mandatory details from your AT&T account:
- AT&T account number, found on your AT&T bill (9 or 12 digits for postpaid, 2 digits for prepaid).
- Number Transfer PIN (NTP), a temporary authorization code you must generate from AT&T.
- Full name of the account holder and the exact billing address associated with your AT&T account. Mismatches can cause rejections.
- Billing zip code, which is required information to transfer your number.
How to get your AT&T Number Transfer PIN
The AT&T Number Transfer PIN is valid for 4 days after it is generated. For consumer accounts, the NTP is a 6-digit PIN; for prepaid accounts, it is a 4-digit PIN. Use one of these three methods to generate it:
- Dial *PORT (*7678) from your AT&T phone.
- Open the myAT&T app, go to More > Manage Profile > People & Permissions > Transfer phone number > Request a new PIN.
- Log in to your myAT&T profile online and follow the same path to request a new PIN.
Write down the NTP immediately and note its expiration date. You will enter it during the Straight Talk activation process.
What you need from Straight Talk
You will need a new Straight Talk SIM card or an eSIM for the device you plan to use. If you do not already have one, you can get a SIM card from Straight Talk online or at participating retailers. You must also verify that your phone is compatible by checking Straight Talk compatible phone models before proceeding. If you have a device that is locked to the AT&T network, you may need to request an unlock code from AT&T to use the device with your new Straight Talk service.
During activation, you will need the IMEI/ESN of the device you intend to use with Straight Talk. You can find the IMEI by dialing *#06# on most phones or checking in the device settings.
Activate and transfer your number on Straight Talk
To begin the transfer process, go to www.straighttalk.com/activate and follow the on-screen steps. Alternatively, you can text TRANSFER to 611611 from your mobile device to receive instructions for porting your number to Straight Talk. You can also activate your Straight Talk service by calling Straight Talk's customer service.
- Insert your Straight Talk SIM card into your compatible phone, or set up the eSIM if applicable.
- Visit the activation page or text TRANSFER to 611611.
- Enter your device IMEI/ESN when prompted. To activate your Straight Talk service online, you'll need to enter the 15-digit SIM card number and the last four digits of your SIM card's serial number.
- Provide your AT&T account number, your Number Transfer PIN (NTP), and the full account holder name and billing address exactly as they appear on your AT&T account.
- Submit the port request and follow any remaining prompts to complete activation.
Once submitted, Straight Talk will coordinate with AT&T to port your number. Do not make any changes to your AT&T account or your new Straight Talk account during this time.
How long the transfer takes and what to expect
Mobile phone number transfers typically take a few hours, but can take up to 2 business days, and in some cases, up to 7 days to complete. It's advisable to initiate the transfer during the weekdays to minimize potential delays that may occur over weekends. The transfer process is complete when your old AT&T phone stops working. That is your signal that the number is now active on Straight Talk.
Be aware that voicemail messages and call history will not transfer from AT&T to Straight Talk. You should save any important voicemails or contacts before initiating the port. You may experience a brief service interruption during the finalization of the transfer.
If you later need to switch your Straight Talk number to a new phone, you can do so through your Straight Talk account settings. Additionally, you can change Straight Talk phone number online if you ever decide to use a different number with your service.
Frequently Asked Questions
Can I transfer a landline number from AT&T to Straight Talk?
Yes, you can transfer a landline number from AT&T to Straight Talk, provided that Straight Talk offers landline services in your area. The process requires the same account information and details as a mobile number transfer.
What if the account holder name on my AT&T account does not match what I enter during activation?
Mismatched account holder names are a common cause of port rejections. Verify that the full name and billing address you provide to Straight Talk match exactly what is on file with AT&T, including any middle initials or suffixes.
What should I do if the port request is rejected?
If the port is rejected, double-check that your AT&T account is active and in good standing, that your Number Transfer PIN has not expired (it is valid for 4 days), and that all personal details match AT&T records exactly. You can generate a new NTP and retry the activation process on Straight Talk.
