How to port AT&T phone numbers to KrispCall

Do you wish to port AT&T phone numbers to KrispCall but are taking a step behind due to the confusion in the porting process?

Worry not!

In this guide, we will walk you through all the requirements, including the steps you need to follow to port your AT&T mobile number to KrispCall. With this, you can ensure a seamless transition.

Porting Requirements (To Be Considered Before Porting Out Your AT&T Phone Number)

Below is a detailed description of a few things you need to consider before initiating the porting process.

1. The Number Must Be Portable

The most important porting requirement is having a portable phone number. KrispCall generally supports porting of all kinds of AT&T phone numbers, but to be on the safe side, it’s always a great idea to make sure of that.

To check whether the number is portable or not, you can go to our KrispCall’s Number Porting Eligibility Checker tool and test it.

2. The Number Must be Active

Other than being portable, the number must also be active and in use. So, before applying for porting, make sure that the number is active.

In case the AT&T number you wish to port is currently inactive, contact the AT&T service provider and request them to activate your number. Then only proceed with the porting process.

3. Clear Outstanding Payments

Before proceeding with the porting process, you should also check if you have any outstanding bills related to call charges, phone bills, equipment fees, or any other bills with AT&T. It’s because you will have to present clear bills to our team during the porting process.

We can’t proceed with porting your AT&T phone number to KrispCall until and unless you have cleared all the dues with AT&T. Consequently, you will face a delay in the porting process.

Lastly, you need to submit correct, up-to-date, and signed documents and information. These documents include,

  • Customer Service Record (CSR)
  • Letter of Authorization (LOA) less than 30 days old
  • Phone Bill
  • 4-digit Number Transfer PIN/ Port-Out PIN Number

Note: These documents must be in KrispCall’s suggested document format.

Information and Document Requirements (To be submitted to KrispCall)

In order to port your AT&T phone number to KrispCall, you will need to provide the following information and documents:

1. Phone Number

You need to submit the active AT&T phone number to KrispCall. Also, make sure the provided phone number is in E164 format.

E164 number format starts with the (“+”) signs, followed by country code, area code, and phone number. Plus, the phone number must not have more than 15 digits. For example, [+][1] [xxx] [xxxx] [xxxx].

2. Letter of Authorization (LOA)

You also need to submit the signed Letter of Authorization (LOA) to port your AT&T number to KrispCall. The LOA verifies that you are an authorized user of the number and provides essential information to porting representatives to transfer a number successfully.

While issuing the LOA, make sure that all the information included is correct and is signed by you (An authorized user or owner of the number). Also, it must not be issued more than 30 days ago.

Here is the LOA template and AT&T’s account authorization form:

3. Customer Service Record (CSR)

A CSR is a report that shows how your telephone records appear in a telephone company’s database. It contains information about the billing address, billing telephone number, name, account type, new service provider name, and so on.

AT&T and KrispCall will use CSR reports in order to ensure a smooth transfer of your phone number.
