WhatsApp number checker (one-click detection of inactive and active numbers)

WhatsApp, as a social chat app, has a major market share overseas, and although it may be less known in China, its influence is significant internationally, with a reported monthly active user count of over 2.3 billion. This is just the number of active users, and the total user traffic is enormous.

Almost everyone in the foreign trade industry uses WhatsApp to communicate with customers because it is a mainstream chat tool abroad.

While WhatsApp has a large number of users, not every user is active. Some users may have multiple phone numbers and register for multiple WhatsApp accounts, but only use one in the end. Therefore, the primary purpose of doing WhatsApp marketing is to conduct WhatsApp number checks.

WhatsApp number checks, according to our marketing strategy, is to check whether a user's WhatsApp account is active, filter out WhatsApp inactive accounts, and get active WhatsApp numbers with just one click.

There are two main steps involved in checking the validity of WhatsApp numbers:

Country code check: First, you need to determine whether the country code of the phone number you want to add is correct. Each country has a specific country code, which is a numerical code that is usually used as a prefix for phone numbers. If you do not know the country code of the phone number you want to add, you can look it up in the international dialing code list.

Number format check: After determining the country code, you need to check whether the number itself meets the formatting requirements for that country. Each country has different number formats, so if the phone number you want to add does not meet the formatting requirements of that country, you will not be able to register on WhatsApp.

WhatsApp number checker is a third-party WhatsApp marketing tool used to determine whether the phone numbers of users in the country or region we have selected have registered for WhatsApp accounts, obtain active WhatsApp numbers, and export them with just one click, making it easy for us to conduct subsequent marketing activities.
