KT Launches New Nationwide Representative Number Prefix '1551' for Service

A Total of 10,000 New Numbers, Nationwide Representative Number Service
Gold Numbers Granted Through Separate Screening

On the 4th, KT announced that it will add the ‘1551’ prefix to the nationwide representative number service, which allows calls to be made using an 8-digit fixed number without dialing the area code anywhere in the country, and will begin providing numbers to businesses. KT received the new ‘1551’ prefix as the existing nationwide representative number resources (1522, 1577, 1588, 1811, 1899, 1533) were depleted.

The ‘1551’ prefix for the nationwide representative number service offers a total of 10,000 numbers, ranging from 0000 to 9999. Businesses such as banks, card companies, logistics, finance, academies, and hospitals can apply for preferred numbers to use as their nationwide representative number. Highly preferred gold numbers like 2424, 7979, 1004, 8282, 2580, 0365, and 1234 can be assigned to businesses upon application after a separate review process.

KT’s nationwide representative number service connects calls made to a single number (1551-****) to pre-designated forwarding numbers such as headquarters or branch call centers. By using KT’s nationwide representative number, businesses can access AI big data services such as basic call processing statistics, forwarding number management, and traffic analysis through the website (bis.kt.co.kr). KT is offering a promotion until October 31, waiving forwarding line fees for three months for new customers who sign up for the nationwide representative number service with a contract of three years or longer.
