Postman: How to Generate Random Phone Numbers Starting with 09/07/01
Struggling to test phone number functionalities? Postman's here to help! Generate random phone numbers starting with 09/07/01 for seamless testing. This guide unveils the code to create these numbers and integrate them into your Postman requests.
When testing APIs, there is often a need to pass phone numbers to the server-side. So, how can we generate random phone numbers and pass them to the API server-side using Postman, a tool for API testing? In this article, we will provide a detailed explanation of the process.
With easy random data generation, find out just what other features Apidog has to offer by clicking the button below.
If you want a more convenient way to generate phone numbers and test APIs, Apidog offers a built-in "Data Generator" tool that allows you to easily generate various types of data, including phone numbers, randomly. Apidog makes it easier to generate random data without writing scripts, making it more convenient than Postman.
Why Pass Random Phone Numbers in API Testing?
There are several typical use cases where phone numbers need to be passed to an API during testing:
- User Registration/Profile Creation
When users register on a website or mobile app, they are often required to provide a phone number as a mandatory field. In this case, the phone number needs to be sent to the server and stored in the user's profile. - Identity Verification/Two-Factor Authentication
For financial services or important transactions, phone numbers may be used for identity verification. One-time passwords can be sent via SMS, or voice guidance authentication can be conducted over the phone. - Shipping/Delivery Address Confirmation
When purchasing products on e-commerce sites, customers may be asked to provide a phone number along with the delivery address. This is used by the shipping carrier to contact the recipient if necessary during delivery. - Marketing and Promotions
Some companies collect customer phone numbers for marketing purposes, such as sending promotional SMS messages, conducting phone surveys, or making sales calls. - Emergency Contact Registration
Phone numbers may be required in various situations, such as registering emergency contacts during job applications or online events.
By using random phone numbers during API testing, you can simulate real-world use cases and conduct more realistic tests.
How to Generate Random Phone Numbers in Postman?
Postman is a popular tool for API development and testing. It allows developers to create HTTP requests and send them to API endpoints, testing the API's behavior and inspecting the request and response data.
To generate random phone numbers in Postman when testing APIs, you can use test scripts.

Step-by-Step Guide to Generating Random Phone Numbers in Postman
Postman has a "Pre-request Script" feature that runs before sending a request. Here, you can use JavaScript to generate a random phone number and store it in an environment variable.
Step 1: Open Postman and create a new HTTP request.
Step 2: Enter the required endpoint URL and parameters for the request, then switch to the "Pre-request Script" and paste the following script:
// Define the phone number format
const phoneNumberFormat = '090-####-####';
// Function to generate random digits, also defining how many digits to generate
function getRandomDigit() {
return Math.floor(Math.random() * 11);
}
// Function to generate a phone number
function generatePhoneNumber(format) {
let phoneNumber = '';
for (let i = 0; i < format.length; i++) {
const char = format[i];
if (char === '#') {
phoneNumber += getRandomDigit();
} else {
phoneNumber += char;
}
}
return phoneNumber;
}
// Set the random phone number as an environment variable
pm.environment.set('randomPhoneNumber', generatePhoneNumber(phoneNumberFormat));
This script generates a random 11-digit phone number starting with 090. The generated phone number is stored in the {{randomPhoneNumber}} variable.
Step 3: In the request parameters, you can reference the {{randomPhoneNumber}} variable to pass the generated phone number to the API server-side.
Open the Postman "Console" to confirm that the generated phone number has been passed.
A More Convenient Way to Pass Random Phone Numbers with Apidog
Instead of manually writing test scripts in Postman to generate and pass random phone numbers, Apidog provides a more convenient solution with its built-in Data Generator tool.
With Apidog's Data Generator tool, you can easily generate data, including phone numbers, based on your needs when testing APIs.
Step 1: Open Apidog and create a new HTTP request.
Step 2: When entering parameter values, click the "magic wand" icon to open the Data Generator tool. Select "Phone Number" as the data type to generate.
Step 3: Click the "Send" button, and you can confirm that a random phone number has been successfully generated and passed by switching to the "Actual Request" tab.
By utilizing Apidog's Data Generator tool, you can easily generate and pass random phone numbers without manually writing test scripts, making it more convenient than Postman for testing APIs. Consider using Apidog as a tool for more efficient API testing.
Additionally, Apidog also supports the custom script, if this data generator tool of Apidog can not meet your requirements. You can add custom scripts in the "Post-processor" tab, and then fill in the same test script as Postman, then you can use variables to send the random phone number.
Conclusion
We have explained how to generate random phone numbers and pass them to the API server-side using Postman. In Postman, you can use JavaScript in the "Pre-request Script" to generate a random phone number and store it in an environment variable. Then, you can reference the generated phone number using the {{randomPhoneNumber}} format and include it in the request parameters.
Additionally, if you want a more convenient way to generate phone numbers and test APIs, Apidog offers a built-in "Data Generator" tool that allows you to randomly generate various types of data, including phone numbers. Apidog makes it easier to generate random data without writing scripts, making it more convenient than Postman.
Preparing appropriate test data is crucial for API testing. By generating and using random phone numbers, you can simulate real-world scenarios and conduct more realistic tests. Utilize tools like Postman and Apidog to perform efficient and comprehensive API testing.
