The total population of Hawaii is about 1.4 million, which is relatively small compared to larger states like California or Texas.

However, what stands out more than the simple numbers is the diverse mix of Japanese, Filipino, Native Hawaiian, Caucasian, and mixed-race populations, making it one of the most ethnically diverse regions in the United States.

In particular, the population is concentrated on the island of Oahu, where over 70% of the total population resides.

So, when you first visit Hawaii, you often get a feeling of a small city-state rather than an island nation.

There is an interesting fact: the entire state of Hawaii uses just one area code. That is 808.

All the islands, including Oahu, Maui, the Big Island of Hawaii, Kauai, Molokai, and Lanai, are grouped under this single number. In the mainland U.S., it's common for a single city to have multiple area codes, but Hawaii is the opposite. Because it is separated by islands and has a relatively stable population size, it has been able to operate with just one code.

This number, 808, was first assigned in 1957 and has remained unchanged since Hawaii became the 50th state in 1959. It can be considered a symbolic number for Hawaii.

Among locals, having an 808 number gives a sense of being 'local.' It carries a sense of belonging that distinguishes them from outsiders.

When making calls, you must dial a 10-digit number that includes 808. When calling from the mainland to Hawaii, you add a 1, making it 1-808-XXX-XXXX. However, due to the physical distance, some communication plans may treat Hawaii as a separate rate zone, so it's important to check.

There are also numbers frequently encountered in local life. In emergencies, 911 is used, and traffic information can be checked through 511.

Major institutions like the Honolulu City Hall, police department, and education department all use 808 numbers. Community facilities such as Korean markets, restaurants, and churches do the same. Therefore, it's a good habit to always include 808 when saving contact numbers.

For newcomers arriving in Hawaii, setting up communication is a surprisingly important first step. Major carriers like AT&T, T-Mobile, and Verizon all provide services, and activation can be done right in stores in downtown Honolulu. If you don't have an SSN, starting with a prepaid plan is a practical choice.

In fact, many immigrants begin their settlement process this way.

And the 808 number they receive during that process feels like a small signal that their life here has begun, beyond just a means of contact.
