So, you’ve been an AT&T user for a longer period and are looking to make a switch. The good news is that the process is straightforward, and you can do it without changing your current phone number.
Many telecom providers now offer number porting, allowing you to switch carriers while keeping your current phone number. All you need is your AT&T transfer PIN, a new carrier like Verizon, T-Mobile, Mint, or Calilio, and a few account details. From there, the new provider takes care of the process. In this blog, we’ll guide you through each step to transfer your AT&T number easily.

When You Might Need to Port Your AT&T Number?
In several situations, you may want to switch to a new service provider from AT&T. For instance, let’s say you’re moving to a new location with a different area code. But you still want to retain your phone number, even if you’re changing your address.
In some cases, you may also want to port a number from ATT when its service doesn’t meet your requirements. It may be due to poor signal quality, lack of features, or other limitations. By porting your number, you can upgrade to a better service without losing your current number.
How to Port Your Phone Number From ATT?
To port number from ATT, obtain your transfer pin, contact the new service provider, and provide them with the necessary documents, including the transfer pin.
Once they verify the document, they’ll start the porting process. Let’s explore the process in the detail here:

1. Verify Eligibility
Before starting the process, ensure that your number is transferable. To do this, make sure that there are no outstanding bills or contract obligations. Also, ensure that your number is still active or has not been suspended.
Additionally, the number should be registered under your name, or you must be able to verify ownership to authorize the transfer. You can verify AT&T number port eligibility by contacting its customer support.
2. Get AT&T Transfer PIN
The transfer pin is a key that permits the new provider to access your number and begin the porting process. So, get your AT&T transfer pin before requesting a new carrier to transfer your number. Without this pin, they are not authorized to port your number.
3. Choose the Service Provider
Now, once you have an ATT number port pin, choose the service provider to which you’re looking to make the switch. When selecting, make sure that it has all the additional features you’re looking for. Do not forget to check its coverage area and pricing, too.
4. Contact the Service Provider
As you’ve decided on your new provider, contact them to initiate the porting. They’ll ask for some necessary documents such as your AT&T account number, the AT&T Transfer PIN, and any identification they may require. Provide them all the necessary documents.
5. Confirm the Number Porting
Finally, you’ll receive a confirmation from your new provider. Generally, they’ll inform you via email or text once the process is complete.

Things to Consider Before Porting Your Phone Number From ATT
Before you begin ATT number porting, back up all the important data and information to ensure that you don’t lose anything important during the transition process.
Here are some other factors to consider:
New Provider’s Compatibility
Not all providers accept every type of number, especially when you’re moving to VoIP. So, before you choose your new service provider, contact them to confirm whether they allow you to port from AT&T numbers or not.
Your Number is Still Active
Your number must remain active during the transition process. If your number has been disconnected or suspended, you won’t be able to port it. So, make sure that your AT&T number is in good condition even before initiating the porting process.
Contract Obligation
AT&T generally allows you to port your number to other carriers. However, it’s always a good idea to check your current contract and see if there are any obligations or penalties regarding porting your number. If you’re under a contract, termination fees or other charges may apply. So, check them properly before you decide to port your AT&T phone number.
Plan for Potential Downtime
During the porting process, you may encounter a few periods of downtime where your number may not be active. While it usually only lasts for a short time, it’s a good plan to keep an alternative communication method ready for the transition period.
How Long Does It Take To Port A Number From AT&T?
The exact time it takes to port a number from AT&T depends on several factors. Usually, it can take anywhere from a few hours to a couple of weeks.
For mobile numbers, the process is quicker compared to landline numbers. While cell phones are typically ported in one day, landline numbers can take up to three to five business days. The reason for landlines to take more time is that they involve more complex processes. The service providers may be required to verify the physical address associated with the landline number. Sometimes, they even require a physical visit for verification.
Wrapping Up
If you’re not happy with AT&T’s service or features, you can easily transfer to another carrier. Simply get your transfer PIN and provide it to the new service provider alongside other documents. However, be sure that you’re choosing the right provider to port number from ATT. If you’re looking for advanced communication features, consider porting to Calilio. By doing so, you can have access to exclusive VoIP features on your existing phone number. Plus, porting time is also very short, usually within a couple of days. Port your number on Calilio now.
