ESN Full Form
What is the full form of ESN?
Electronic Serial Number is the full name of the term ESN. The manufacturers of wireless phones insert an ESN, a special identification number, into the microchip. The ESN number is sent automatically to a base station whenever someone dials a number. In order to verify the call's legitimacy, the carrier's mobile switching office first looks for the ESN. By taking this action, fraud can be avoided. The ESN's function is to automatically send data to the base station whenever a call is placed. In order to stop fraud, the carrier's mobile switching office also looks for ESN and verifies the call's legitimacy.

Where is the ESN Written?
Currently, CDMA (Code-division multiple access) phones are the major devices that employ ESNs. Instead, IMEI (International Mobile Equipment Identity) numbers are used by GSM (Global System for Mobile Communications) phones.
ESN is often printed on a label that is placed under the battery of a cell phone. It has a 32-bit serial number, of which 18 bits have a unique serial number, 8 bits reflect the manufacturer code, and 6 bits are reserved for potential usage in the future. Each mobile device is given an ESN code in order to uniquely identify it.
History of ESN
Early in the 1980s, the United States Federal Communications Commission, also known as FCC, assigned ESN.
ESNs were initially implemented for Advance Mobile Phone Services (AMPS), the very first analogue mobile phone technology.
Every time a phone is used, an ESN and a MIN (Mobile Identification Number) are automatically sent to a wireless network. It links that phone to the subscriber's account and number.
In 1997, the Administrations were taken over by the Telecommunications Industry Association.
In 2006, the manufacturers began to run out of distinctive ESNs. The shift to a new Mobile Equipment IDentifier (MEID) standard that could take the place of ESN was ultimately necessary.
Based on applications submitted before June 30, 2010, there might be a future occurrence. However, current research indicates that no more assignments of this nature were made after December 31, 2010.
The Main Objective of ESN
When a user makes a call, ESN immediately sends data to the base station. To confirm the legitimacy of the call, the carrier's mobile switching office further discovers this ESN.
The ESN's main goal is to stop fraudulent calls.
A Multistage Interconnection Network (MIN), which is a network identification for a wireless carrier's phone, is different from an ESN.
The ESN and MIN of a device can perhaps be checked electronically to assist thwart fraud.
Applications of ESN
Using the ESN, wireless phones can be tracked and expelled from the network as necessary.
In theft situations, ESNs are incredibly helpful.
Through the use of the phone's specific ESN, one can track a stolen phone and, if necessary, block it.
The ESNs from stolen phones are kept on file by various network service providers in various locations. These devices are referred to as poor ESN phones.
Advantages of ESN
- ESN's advantages include improved efficiency because its Information manual is simple to find and track down.
- Since the Public switched telephone network ( pstn office) has screened all incoming calls, the user can rest easy. The legitimacy of the calls is provided by the detected ESNs. ESN eliminates fraud.
- It makes better use of board space and dependability because fewer connecting pins are used.
- It is simple for the ESNs to identify and demonstrate which devices placed and received calls.
- In order to trace manufacturers and their inventories for warranty claims, ESNs can also be used.
Drawbacks of ESN
Data sifting by ESN takes a while. Due to how long the ESN service takes to start, it may create delays when starting.
If you use Radio Frequency (RF) for serial number capture, you must manage the RF infrastructure (hardware and network) and software. Both the warehouse and Information Technology ( IT) industries will incur additional costs.
The expense of maintaining customised IT systems will always increase.
Businesses can be impacted by programming flaws/inefficiencies.
Added transactional compliance requirements are imposed by ESN. As a result, more scans and entries must be made by the warehouse workers in order to accurately capture the necessary data.
Serial number entry problems and mistakes are increased when done manually.
