How does a cross-border e-commerce merchant generate a WhatsApp customer number? The Complete Guide to Bulk Customer Acquisition

  • 2026-02-26

Preface

Today, as cross-border e-commerce competition becomes increasingly fierce, many sellers have begun to focus on WhatsApp private domain marketing to acquire customers. Compared with advertising, WhatsApp reaches customers more directly and has lower conversion costs. But many teams will encounter a problem: not enough target customer number resources .

Especially for teams that have just entered overseas markets, it is difficult to establish a high-quality customer number pool in a short period of time. So here comes the question: How does cross-border e-commerce quickly generate potential customer numbers in the target country?

This is why many sellers start using Dingdang Assistant .

Why cross-border e-commerce needs to generate numbers in batches

In the traditional customer acquisition model, cross-border e-commerce mainly relies on:

  • Facebook ads
  • Google ads
  • Platform natural traffic
  • KOL cooperation

However, as traffic costs rise, more and more sellers have begun to establish private domain traffic pools . And WhatsApp has become an important channel.

However, the reality is:

  • Many teams don’t have customer numbers
  • Market data is fragmented
  • Low customer acquisition efficiency

If the number pool cannot be quickly established, it will not be possible:

  • bulk marketing
  • Customer Reach Test
  • Market validation

At this point, number generation tools become critical infrastructure .

How to batch generate target country customer numbers

For cross-border e-commerce, number generation is not simply random, but requires market logic :

For example:

US market:
+1 area code + operator number segment + user number

UK market:
+44 area code + local number range

Problems with traditional manual processing:

Low efficiency

error prone

Data structure is confusing

Through Dingdang Assistant , you can achieve:

This allows cross-border teams to build an initial customer database in a short period of time.

How to improve marketing success rate after generating numbers

Simply generating numbers is not enough, what is more important is number screening and cleaning .

Many teams overlook one thing: not all numbers can be used for marketing.

Highly effective teams typically:

  • WhatsApp number screening
  • Active number identification
  • Data deduplication
  • market grouping

Through the complete process: number generation → number screening → customer grouping → marketing contact

Only in this way can we truly establish a sustainable customer acquisition system.

And that’s why more and more cross-border teams are using specialized tools to get the job done.

Conclusion

For cross-border e-commerce, data is the starting point for growth . Without customer number resources, any marketing strategy will be difficult to implement.

By rationally using number generation and cleaning tools, teams can quickly build their own customer database and continuously optimize customer acquisition efficiency.

This is also an important reason why many sellers start using Dingdang Assistant for market expansion.
