If you are engaged in cross-border marketing, overseas group building, private domain operations, and outbound telemarketing, the biggest obstacles you may face are not poor channels or unattractive content, but:Most of the numbers you have may be invalid..

When you send group messages, make outbound calls, or send text messages, you get no response, no connection, or even the account is blocked. This reminds you:There is a problem with the number database.

This article will tell you how to judge from a practical perspective"Reliable empty number detection service" and recommends a solution suitable for global number cleaning - specially designed for cross-border scenarios.

why sayIs it so difficult to find “reliable testing services”?

The detection number database seems simple, but there are several technical and resource thresholds behind it:

lA large number of global operators and widely differing rules

lReal-time status detection needs to be connected with the operator or signaling node

lMulti-country, multi-number, multi-platform registration status identification requires technical accumulation

lBatch processing requires high concurrency support and stable interfaces

lLabeling results and structured output require data governance capabilities

If the service provider only"Number format verification" or "simple interface call" are far from the standard of true "available number cleaning". If you choose the wrong service and the number database is not cleaned thoroughly, subsequent marketing will still fail.

Key criteria for judging the reliability of testing services

When you compare various service providers, you can judge from the following dimensions:

lCountry coverage: Whether to support key markets such as Europe, America, Southeast Asia, Latin America, and the Middle East

lDetecting dimension richness: Whether to identify empty numbers, shutdown numbers, downtime numbers, social platform registration status, risk number segments, etc.

lBatch processing capability: Whether to supportList detection of 100,000 or more than one million items with stable speed

lResult output format: Whether it has a status label, whether it can be directly classified and exported, whether it can be passedAPI access system

lTechnical Compliance and Security: Whether it can be detected without sending the actual message to avoid the risk of mass sending

If a service is weak in supporting multi-country number ranges, can only detect formats, and exports few fields, it may just"Format verification", not "number availability cleaning".

Recommended solution: A process suitable for global number cleaning

The following is the standard process we recommend for global number cleaning, which is suitable for cross-border SMS,WhatsApp group messaging and outbound telemarketing team:

1. Import number list

Before cleaning, sort out all the mobile phone numbers to be processed (it is recommended to unify the country code+number format).

2. Use professional testing platform for screening

Choose a service provider with high coverage and rich dimensions (such asdigital planet), perform empty number detection, shutdown detection, registration status detection, etc.

3. Export test reports and classify them

After detection, the status label of each number is obtained, such as: real number, empty number, powered off, logged out, and not registered. reserve"Real number" is reached, and other categories are processed or eliminated separately.

4. Import group sending or outbound calling system

Import the filtered real numbers into yourWhatsApp group messaging tool, outbound phone call system, SMS platform, etc. perform reach-out.

5. Establish a number health mechanism

Combine the detection results with marketing feedback data (successful delivery rate, connection rate, response rate) to continuously optimize the number pool and avoid old data becoming"Dead number pool".
