How to obtain US mobile phone number resources at low cost? Dingdang Assistant helps enterprises build high-quality number pools

At a time when global digital marketing is rapidly evolving, the United States is still one of the most competitive high-value markets. Whether the company is engaged in cross-border e-commerce, financial services, local life, app promotion or SaaS overseas, has always been a core topic for the marketing team.

Content advertising prices have risen, privacy policies have tightened, and third-party data has become difficult to obtain, making traditional delivery methods increasingly expensive. Enterprises need to establish new user acquisition channels, and the "mobile phone number resource library" that can support long-term reach and stable accumulation is becoming the preferred strategy of many overseas teams.

Dingdang Assistant uses "number generation + intelligent screening" as its core capabilities, allowing companies to independently build a potential user pool in the United States without relying on expensive purchasing channels. Rather than being a number tool, it is better to say that it helps companies build a scalable, scalable, and reusable marketing data asset system .

Why are U.S. mobile phone number resources the most valuable marketing asset to invest in right now?

The United States is one of the most digitally mature countries in the world, and its users are highly dependent on mobile phone numbers. From registering for apps, receiving discounts, receiving verification codes, to participating in sweepstakes and subscription activities, mobile phone numbers are still the most important identity anchor for American users. This brings advantages at three marketing levels:

1. The mobile phone number channel is more stable and is not affected by the platform algorithm.

Unlike social platforms and advertising platforms, marketing channels based on mobile phone numbers (such as SMS, WhatsApp, outbound calls, member recall, etc.) are not affected by algorithm fluctuations and bidding pressure.

When there is a U.S. number pool of sufficient size, no additional advertising budget is required, it will not be affected by platform throttling, information transmission is more direct, and long-term costs are controllable and predictable.

This gives companies greater underlying stability in a highly competitive market.

2. The U.S. area code segment has clear rules and is suitable for batch generation and regional reach.

The area code segments of every state and city in the United States are open and transparent, which gives number deduction a natural advantage.

For example: users in California and Texas prefer e-commerce promotions; users on the East Coast have higher demand for credit and financial products; technology industries are concentrated in San Francisco and Seattle; some states have higher SMS reception rates and lower costs.

Having a clearly structured number pool means that companies can conduct regional marketing strategies by region, user value, and industry.

3. The number of WhatsApp users in the United States is growing rapidly, and the value of numbers is increasing.

The United States was not a core market for WhatsApp in the past, but it has grown rapidly in recent years, with more and more users using WhatsApp to communicate with merchants. Having a large number of potential U.S. numbers means more opportunities are activated and more access paths are opened. Therefore, the US number pool is becoming the most investment-worthy infrastructure for enterprises’ “future marketing”.

How Dingdang Assistant helps enterprises build a U.S. number resource pool

The price of U.S. mobile phone number resources on the market is not low, and the data sources are often opaque and mixed with a large number of virtual number segments and invalid numbers.
The advantage of Dingdang Assistant is that enterprises no longer need to spend money to purchase numbers, but can generate and verify numbers independently , which greatly reduces customer acquisition costs.

1. Large-scale generation based on number system: Constructing a “potential U.S. user map”

The U.S. number format rules are clear. Dingdang Assistant can quickly generate a large number of potential numbers based on public information such as national structure, area code segment, operation combination, and establish a basic user database covering the entire country for enterprises.

These numbers can be used for: WhatsApp reach/SMS promotion/Outbound call research/App promotion/Independent station conversion improvement/User recall marketing

Businesses no longer need to rely on expensive or unstable third-party data providers.

2. After generation, filter out high-quality numbers through the "number filter"

Dingdang Assistant does not just generate, but provides a complete closed-loop process.
The generated numbers are imported into the screening system to complete: cleaning of invalid numbers, filtering of abnormal formats, identification of virtual number segments, filtering of downtime/inactive numbers, elimination of structural abnormalities, deduplication and hierarchical organization.

What remains after filtering are high-value U.S. numbers that are more likely to be real online. This step is equivalent to turning "crude data" into "disposable data assets".

3. Further precipitate the multi-layer structured number pool

When an enterprise accumulates a sufficient scale of U.S. numbers, it can form differentiated number pools through multiple generation, screening, and classification management, such as: U.S. high-activity WhatsApp number pool/U.S. high-value area (such as California, Texas, Florida) number pool/Low-resistance state number pool suitable for SMS marketing/Segmented user pool for specific product scenarios

This kind of data stratification allows enterprises to have higher accuracy, lower cost, and stronger controllability in delivery.

Utilize high-quality US number pool to achieve low-cost customer acquisition and growth flywheel

Having a well-structured number pool not only allows companies to reduce advertising costs, but also creates growth "compound interest" across multiple channels.

1. Multi-channel reach is more efficient and unit costs continue to decrease

Based on the US mobile phone number, it can be activated: WhatsApp message contact, SMS marketing, outbound phone calls, CRM private domain connection, Email + SMS mixed contact, event promotion reminder, member repurchase recall

The same number is reused in different channels, bringing about the "asset reuse effect". The cost of acquiring customers for an enterprise decreases the more it is used.

2. More suitable for regional A/B testing to improve advertising ROI

User behavior varies greatly in different regions of the United States. Number pools can help companies conduct experiments in different states to determine which regions are more willing to accept WhatsApp messages, which states are more price-sensitive, which users are more suitable for SMS marketing, and which cities have lower activation costs.

Through continuous experimentation, companies can find the most cost-effective regional placement strategy .

3. Data accumulation creates long-term advantages, rather than “traffic that disappears after buying once”

The biggest problems with externally purchased data are: uncontrollable quality, difficulty in reuse, high expiration rate, and difficulty in long-term storage

The number pool built using Dingdang Assistant: can be continuously expanded, can be repeatedly verified, can be managed hierarchically, can be reused across channels, and data assets continue to grow on a rolling basis.

This is a growth method that can truly enable companies to reduce customer acquisition costs year by year.

Conclusion

In a highly competitive market like the United States, rising marketing costs seem to have become an industry trend, but this does not mean that companies can only passively accept it. The number generation and intelligent screening functions provided by Dingdang Assistant allow companies to build their own pool of potential U.S. users at a very low cost. For marketing teams who need to expand the US market in the long term, this is not only a tool, but also a marketing infrastructure that can reduce customer acquisition costs and improve reach efficiency in the long term.

Building a U.S. number pool is building a company’s future growth infrastructure.
