Which Hotline Number Should Businesses Choose?
1900 Hotline Number
The 1900 hotline number is currently one of the most popular choices in the market, offering high flexibility and not being limited by area codes or specific geographic locations. This makes it an ideal choice for operations such as customer service, sales consulting, providing business services for chain stores, managing transportation activities, or ticket reservations.
Businesses register for the 1900 hotline number with telecom providers to establish an effective connection with customers. However, it functions solely as an inbound call line and cannot make outbound calls.
The cost for callers ranges from 1,000 VND to 8,000 VND per minute, depending on the telecom provider, and businesses will receive a portion of the call charges, usually ranging from 26% to 40%.
Advantages
Recently, the 1900 hotline number has gained significant preference among Vietnamese businesses due to several notable advantages:
- Simplicity and Easy to Remember: The 1900 hotline number is short and easy to remember, which helps stimulate interaction between customers and businesses.
- No Area Code Boundaries: One of the standout features of the 1900 hotline number is that it is not tied to any specific area code, allowing customers from all over the country to easily contact the business. This is especially beneficial for national PR campaigns and brand promotion strategies.
- Opportunity for High Call Revenue: Not only does the 1900 hotline serve as an efficient communication channel for customer service, consulting, and sales activities, but it also offers the potential for high revenue from incoming calls due to the ability to share a portion of the call charges.
- Supports Multiple Calls Simultaneously: The 1900 hotline can handle multiple calls at the same time, creating a professional and reliable image for the business
Disadvantages
Despite its notable advantages, the 1900 hotline also has some limitations:
- Call Charges for Customers: The 1900 hotline charges the caller, which requires businesses to inform customers of the call charges before they make contact. This could potentially raise concerns or cause hesitation among customers.
- Short Number Format and Strict Registration Requirements: The concise format of the 1900 number and the high demand for such numbers, along with strict registration policies, can make it difficult for businesses.
- Inbound Calls Only: The 1900 hotline number is only capable of receiving inbound calls, meaning that businesses need to incur additional costs for setting up another system for making outbound calls.
1800 Hotline Number
The concept of a hotline number carries significant meaning and offers a range of options for businesses. In the diverse market today, the 1800 hotline number stands out as one of the most popular and highly regarded choices. It’s simple and quick registration process, combined with flexible functionality, makes it particularly suitable for customer service and technical support needs of businesses.
One of the standout features of the 1800 hotline system is that it is toll-free for customers. Businesses can register the hotline and bear the costs associated with incoming calls. This not only provides convenience for customers but also helps businesses save on call charges.
Additionally, the 1800 hotline is designed to only receive inbound calls, not make outbound calls, which enhances security and control during communications.
Advantages
The 1800 number is one of the nationally unified hotline numbers that have been widely adopted by businesses. This system offers several significant advantages:

- Seamless Integration with Call Center and Sales Hotline Systems: The 1800 hotline can be easily integrated with call center software and sales hotline systems, providing businesses with an efficient solution to handle customer service.
Disadvantages
The 1800 hotline number is a toll-free line, but businesses will have to bear the entire call cost and may find it difficult to control expenses due to the varying call durations. The complete toll-free nature also brings risks of disruption, causing difficulties in business operations.
Moreover, the 1800 hotline can only receive incoming calls, so businesses will need to pay extra to register another line for outgoing calls.

Commonly Used Hotline Numbers Today
Fixed Number Hotline
In addition to the two types of hotline numbers mentioned above, the fixed number hotline, which uses advanced IP technology, is increasingly popular among many businesses. This type of hotline system allows businesses to easily receive incoming calls and make outbound calls with a single contact number.
Currently, this type of hotline number is only granted to registered businesses that provide customer support, sales consulting, telesales, and similar services.
Advantages
Using a fixed number hotline offers a lower monthly cost compared to the two previous types of hotline numbers, while also providing the ability to make and receive calls, offering convenience for businesses.
Each line with a fixed area code helps easily identify the company’s business location. Notably, this number is only issued to registered businesses, which helps prevent customers from accidentally contacting the wrong number or reaching an unreliable entity.
Disadvantages
However, the fixed number hotline has a format of up to 11 digits, making it difficult to remember and posing a challenge for customers when they need to contact the business.
Additionally, each hotline is tied to an area code, which can create difficulties for businesses in synchronizing operations when they have multiple branches or business units. Furthermore, this can also hinder the company’s promotional and PR strategies.
Mobile Hotline Number
Mobile numbers for hotlines are quite easy to register, with a format similar to personal contact numbers. They are increasingly used by small businesses as a solution for hotline services, such as customer support, sales consultation, and managing order communications.
Advantages
Mobile hotline numbers are an extremely popular choice due to their low monthly fees and independence from area codes, making communication easier. The flexibility of these numbers provides variety, allowing businesses to choose a number according to their preferences.
Disadvantages
However, the personal number format may cause hesitation for many customers when contacting. Additionally, the high out-of-network call charges can be a barrier for businesses when choosing this option.
