ESP8266 get mac adress

This tutorial explains how to get mac address of ESP8266? All esp8266 comes with unique address which is factory programmed. A MAC address is given to a network adapter when it is manufactured. It is hardwired or hard-coded onto your network interface card (NIC) or chip and is unique to it. Something called the ARP (Address Resolution Protocol) translates an IP address into a MAC address.

For this reason, the MAC address is sometimes referred to as a networking hardware address, the burned-in address (BIA), or the physical address. Here’s an example of a MAC address for an Ethernet NIC: 00:0a:95:9d:68:16.

In ESP8266 you can get the MAC address using simple command


Example Program to read mac address of ESP8266

 * Get MAC Address of ESP8266 in Arduino IDE
#include <ESP8266WiFi.h>

  const char* wifiName = "";
  const char* wifiPass = "your_password";

// the setup function runs once when you press reset or power the board
void setup() {
  // We start by connecting to a WiFi network
  Serial.print("ESP8266 MAC: ");
  Serial.print("Connecting to ");

  WiFi.begin(wifiName, wifiPass);

  while (WiFi.status() != WL_CONNECTED) {

  Serial.println("WiFi connected");
  Serial.println("IP address: ");

// the loop function runs over and over again forever
void loop() {

This program prints the MAC address of ESP8266 on Serial terminal, After uploading open serial monitor to see ESP8266 MAC address.
