What is a long code (phone number)?

Long code is a term used in the telecommunications industry to refer to a 10-digit phone number used for two-way communication. It is also known as a dedicated virtual number or a long virtual number. Long codes are used for various purposes, including customer feedback, surveys, notifications, and two-factor authentication (2FA). 

What is an example of long code?

An example of a long code would be a 10-digit number that looks like a regular phone number, such as (555) 123-4567. Long codes are not standardized, and every number is unique. Therefore, businesses can use any 10-digit number as a long code. 

What are the advantages & disadvantages of long code?

Long codes have several advantages and disadvantages. The primary advantage is cost. Since long codes are regular phone numbers, they do not require additional fees to acquire. Long codes also have a high throughput rate, meaning they can handle a large volume of messages. 

A disadvantage of long codes is that some mobile carriers may block messages from long codes, or the messages may be filtered into the spam folder, which could affect the reliability of communication.  

When should I use long code?

Businesses should use long codes when they need to establish a personal connection with their customers. Long codes are an excellent choice for sending notifications, customer feedback, and surveys, as they allow businesses to receive responses from their customers. Additionally, long codes are great for two-factor authentication, which requires a high level of reliability.
