1. Why is number testing more necessary for market launch in the United States?
As one of the centers of the global digital economy, the United States has a highly sensitive user base and a strong aversion to spam marketing. The FCC (Federal Communications Commission) has strict regulations, which makes advertising activities face more compliance challenges:
lHigh complaint sensitivity, users tend to directly report unknown marketing calls;
lThe platform mechanism is mature, such as operators automatically blocking high-frequency harassing calls;
l Multi-channel linkage blocking, once flagged, may affect Multiple channels for SMS, WhatsApp, and voice;
l Some numbers are in Do Not Call list (DNC), illegal calls will face the risk of legal action.
Therefore, in-depth inspection of the number's source, status, behavior label, and whether it is on the complaint list is a prerequisite for ensuring the stability of project delivery.
2. Common number risk types in the U.S. market
In the experience of detecting millions of local numbers in the United States, we have concluded that the following types of high-risk numbers must be eliminated before being released:
l Empty number: Already logged out or invalid, unable to communicate, wasting access resources;
l Outage number: It may be a short-term suspension, or it may be a long-term deprecation, and it is not recommended to access it;
l Complaint number: There is a historical complaint record and it has been marked as harassment by multiple platforms;
l blacklist number: Is on a negative list shared within the enterprise, platform or external suppliers;
l DNC list: Users actively register to refuse any commercial calls or text messages;
l forwarding number : Suspected virtual numbers or number segments are often used by crawlers /registration/fraud;
l High frequency contact number: has been called repeatedly by a large number of advertising companies, and users are extremely annoyed;
l Virtual carrier number: The stability is poor and the complaint rate is high. It is not recommended to release it in large quantities.
Only through systematic inspection can these "Invisible minefield" to truly build a high-quality delivery list.
3. Complete dismantling of the testing process: from original numbers to precise lists
In actual operations, number detection in the U.S. market requires the following five-step process, and each step cannot be omitted:
1. Data structure verification
First, clean the original number file to eliminate format errors, inconsistent digits, duplicate numbers, blank lines and other invalid data to ensure that the numbers entering the detection system have basic communication capabilities.
2. Real-time status recognition
pass API real-time access method identifies communication status such as whether the number is "on the Internet", "offline", "virtual number", etc. This step provides data basis for subsequent grouping.
3. Risk label comparison
Use the third-party complaint database and historical delivery feedback system to check whether the number is on the blacklist, complaint list or DNC list. The key to this step lies in the coverage and update frequency of the data source.
4. Behavioral Characteristic Screening
Registration platforms that combine numbers (e.g. WhatsApp, Signal), whether to access social accounts, historical call rate and other behavioral tags to further rate the number’s accessibility and interaction possibilities.
5. Availability tiering
Divide all numbers into three levels according to risk levels: high risk (unavailable), medium risk (use with caution), and low risk (recommended to be released), and output a list file that can be directly imported into the system to facilitate subsequent use of outbound calls or mass messaging systems.
4. Differences in number requirements for different delivery channels
Outbound call strategies in the U.S. market vary due to channel differences (such as phone calls, text messages, WhatsApp) has different requirements, and the detection granularity should be adjusted accordingly:
l Outbound calls : Focus on preventing DNC list and complaint number to ensure legal compliance;
l SMS marketing: Pay attention to the transfer number, virtual operator number, and outage number to ensure the delivery rate;
l WhatsApp delivery : Should check whether to register WhatsApp, and activity tags;
l Messenger/Signal/TikTok delivery: You need to cooperate with the social account identification function to screen out real interactive users.
The Digital Planet platform can output multi-dimensional detection results according to different channels and adapt to multiple delivery strategies.
5. How much cost can be saved by pre-launch testing?
Many companies may initially mistakenly believe that "Testing is an additional cost", but this is not the case.
l Assume that a delivery goal is If 100,000 numbers are not tested, an average of 40% will be invalid/high risk;
l Assume cost per dial 0.3 yuan, if the delivery system is executed 100,000 times, it will lose 12,000 yuan;
l If it is cleaned in advance through Digital Planet, only the 60,000 highly available numbers, which saves costs by more than 5,000 yuan;
lMore importantly, the system will not be restricted due to repeated complaints or account bans, and the marketing link will be more long-term and stable.
Therefore, batch number detection is not only a tool for cost control, but also an infrastructure for improving conversion rates and reducing compliance risks.
