What is US data? What types are included?

Main types of US data: numbers, social accounts and behavioral data

In the scenario of B2B SaaS overseas customer acquisition, “US data” usually refers to the following three categories:

• US phone number: includes numbers generated from mobile numbers and fixed number segments, corresponding to the +1 area code of the NAFTA region (partially shared by the United States and Canada). The original number itself has no marketing value and needs to be tested for platform validity.
• Social account data: Such as Telegram ID, WhatsApp ID, Line UID, Zalo account, etc. These accounts are usually bound to numbers, and after filtering, derived fields such as activation, activity, gender, age, etc. can be obtained.
• Behavioral data: refers to user active period, last online time, device type and other information obtained through detection (such as iOS device, blue number, etc.), which is used to determine whether the user belongs to a high-intent group.

Core differences between U.S. data and data from the rest of the world

Dimensions	United States data	Rest of the world (such as Southeast Asia, Europe)
Number format	+1 10 digits (such as +1 212 xxx xxxx), number segments are widely distributed	Different lengths, such as +86 11 digits, +44 10 digits
Operator characteristics	AT&T, Verizon, and T-Mobile are the three giants, with high number reuse rate	Many small operators, number segments are active and changing
Compliance environment	Regulated by CCPA (California), TCPA (federal), and FCC, data use requires explicit authorization	GDPR (Europe) is more stringent, and regulations in some areas are vague
Privacy awareness	Users have low tolerance for harassing calls, and attention should be paid to activity and compliance when screening	Some markets are more receptive to marketing messages

Understanding these differences will help you properly configure detection types when screening US data to avoid account risks caused by excessive exposure.

How to get US number data? What are the legal channels?

Free to generate vs paid to buy: Which one is better for you?

There are two main legal ways to obtain the raw data of a US number:

1. Number segment generation: Randomly generate numbers based on known US number segments (NPA-NXX). This method is completely free, does not involve third-party data sources, and has the lowest compliance risk. The generated number can be used for subsequent screening.
2. Paid number pool purchase: Purchase a filtered number list from a regular data service provider. Note: Many cheap “beautiful accounts” or “accurate customer data packages” may come from illegal products, and subsequent use may easily result in complaints or account bans from the platform.

For early testing or teams with limited budget, it is recommended to try free number segment generation first. If you need to move forward quickly in large quantities, paid purchases can be used as a supplement, but be sure to confirm the legitimacy of the data source.

Why is number segment generation a compliant and less expensive option?

The number segment generation does not contain any private information of real users, but only constructs a number combination according to the number allocation rules. Its core value is that you only need to pay the screening fee (deducted per item), and the generation process itself costs zero. Especially in the US market, the number segment coverage is comprehensive (240+ countries) and can be accurate to the state or city level. The generated number can be directly imported into the screening module to check the validity and activity of platforms such as Telegram and WhatsApp.

How to filter valid US customer acquisition data? Key steps and metrics

Multi-platform screening: How to choose Telegram, WhatsApp, Line, Zalo and other platforms?

The penetration rates of U.S. users on different platforms vary greatly:

• Telegram: There are relatively active cryptocurrency, developer, and community groups in the United States, and it is suitable for B2B private domain traffic.
• WhatsApp: The number of local users is lower than that in Southeast Asia, but it is frequently used in cross-border business scenarios and is suitable for customer service and notifications.
• Line: There are few users in the United States, mainly for Japanese companies or specific communities.
• Zalo: Almost only used in the Vietnamese market, it has little significance for acquiring customers in the United States.
• iMessage/iOS: Detect whether the device is an iPhone (blue number) and enable iMessage marketing within the iOS ecosystem (subject to Apple policies).

It is recommended to selectively test according to the customer acquisition target: if you focus on the Telegram community, only check Telegram activation and activity detection; if it is a cross-border e-commerce independent station, you can add WhatsApp and iOS blue number detection.

Activity and gender screening: How to identify high-intent users?

Pay attention to the following fields when filtering:

• Activation Test: Confirm whether the number is registered with the platform. This is the basic threshold.
• Activity: Specify the latest active window (such as 7 days, 30 days, 90 days). Users who have been active recently have a higher response rate.
• Gender and Age: Some platforms (such as Telegram, Line) can return the gender and age fields filled in by users, but the accuracy is not 100%. Please do not treat it as ID card-level data. For example, “tg 30-year-old data” means that the age field in the detection results can be used to filter user groups around 30 years old.

Data deduplication warehouse: Why can it significantly reduce duplication costs?

Each time the number is filtered, the balance will be consumed. If the same number is submitted multiple times, it will be wasted. KK-DATA’s deduplication warehouse will automatically compare historical detected numbers before submitting a new task to avoid repeated detection. For long-term teams, this feature can reduce costs by 30%–50%. It is recommended to record the numbers uniformly when generating or importing them to achieve maximum deduplication.

How is the price calculated for US data screening? Key points of cost control

Pay-per-item vs. subscription-based: Which one is more suitable for small and medium-sized teams?

US data screening platforms usually have two charging models: subscription (monthly/annual fee) and billing by item. For small and medium-sized teams, billing by item is more flexible:

• There is no fixed expenditure, and the difference in cost between 100,000 tasks and 1 million tasks is controllable.
• The budget can be adjusted according to the project cycle, without locking in large packages in advance.
• Different platforms have different detection unit prices. For details, please refer to the real-time price of the console or the official website billing page.

KK-DATA adopts purely per-item billing, with no subscription package. After recharging the balance, the fee will be deducted according to the actual number of detected items. The estimated cost will be displayed before the task is submitted to facilitate budget approval.

How to reduce unit costs through task planning and deduplication?

• Batch Integration: It is recommended to accumulate at least 10,000 numbers for a single task before submitting, to avoid starting small tasks frequently (each task has minimum processing overhead).
• Duplication removal: When generating or importing numbers, first use the deduplication warehouse to filter the detected numbers.
• Dynamic adjustment of detection type: If the target market is low in activity, you can temporarily turn off gender or age detection and only enable + active, which greatly saves costs.
• Utilize nighttime idle periods: Some platforms have short task queuing times during off-peak hours, but the actual deductions have nothing to do with the time period, and billing on a per-item basis remains consistent.

What are the compliance requirements for U.S. data use? (CCPA and industry standards)

The TCPA (Telephone Consumer Protection Act) at the federal level in the United States prohibits the sending of automated outbound calls or text messages to mobile phone numbers without consent. CCPA (California Consumer Privacy Act) gives users more control over the collection and use of personal information by companies. This means:

• You need to ensure that the data source is legal (such as number segment generation, which does not involve the initial collection of real user privacy).
• The number obtained by screening can only be used for channels for which the user has given consent. For example, if a user has signed up for Telegram and accepts group messages, he or she can be imported into the group; however, if the number has never subscribed to your service, sending marketing text messages directly may violate the rules.
• Data must not be used for illegal activities, such as fraud, volume brushing, and harassment.

Compliance is not only a legal requirement, but also related to platform account security. Telegram, WhatsApp, etc. all have anti-spam mechanisms. Using inactive or involuntary numbers to add a large number may result in account ban.

In the overseas customer acquisition scenario, what are the best practices for US data?

• Cold start phase: Prioritize the US numbers that have been activated on Telegram and have been active in the past 7 days to join the early seed user group. The number should not be too large (200-500 items per day) and should be gradually increased.
• WhatsApp Marketing: With iOS blue number detection (iMessage valid users), soft notifications (such as discount reminders) are sent, but the frequency needs to be limited. It is recommended that each message be separated by more than 3 seconds to avoid being marked.
• Data Integration: Export filter results to CSV and import into CRM or marketing tools, ensuring field alignment (such as tgid, wsid). For Telegram, you can use tgid to add friends directly, which is more efficient.
• Continuous Verification: Number status will change dynamically - users who activate today may log out tomorrow, so it is recommended to re-screen the core data pool every 3–6 months.

FAQ

Q: Does the U.S. data contain actual personally identifiable information (PII)?

Answer: Usually refers to contact information such as phone number, social account, etc., excluding ID number, address, and financial information. When using it, you should confirm that the data source is legal and avoid collecting sensitive personal information.

Q: How long does it take to sift through U.S. data?

A: Depends on the number of tasks and detection type. For example, the detection of 100,000 Telegram activations is usually completed within a few hours. After the task is submitted, the console displays the progress in real time, and notifications can be received through Telegram when completed.

Question: What should I do if the screening number fails or the balance is insufficient?

Answer: If the balance is insufficient, you will not be able to submit new tasks, and you need to recharge first (USDT TRC20, the minimum is about 50 USDT). If the task fails due to system abnormality in the middle, the unconsumed detection amount will not be deducted, and the details will be subject to the console record.

Question: How to ensure that data is deduplicated and not missed?

Answer: KK-DATA provides a cross-task data deduplication warehouse, which automatically compares historical numbers before each screening to avoid repeated detection. It is recommended to record the numbers uniformly when generating or importing them to achieve maximum deduplication.

Question: Can U.S. data be used for overseas advertising?

Answer: Yes, but you must comply with the advertising policies of each platform. The valid numbers obtained by screening can be used for Facebook Custom Audiences (subject to hashing), Google Customer Match, etc., but unauthorized numbers cannot be used to initiate marketing calls or text messages (which may violate the TCPA).
