US Data Frequently Asked Questions 10 Questions 10 Answers: Complete Guide to Number Obtaining, Platform Screening and Overseas Customer Acquisition

When overseas teams and cross-border e-commerce companies develop the North American market, “US data” is an almost unavoidable basic resource. Whether you are doing Telegram community operations, WhatsApp private message promotion, or reaching iOS users through iMessage, mastering a batch of high-quality and highly active U.S. numbers can greatly increase the customer acquisition conversion rate.

But in actual work, we often encounter various problems: Where can I get a US number? What platforms does Sieve Support support? How to tell if a number is really active? How much money is wasted on repeated testing? This article uses 10 high-frequency questions + detailed answers to help you clarify all key aspects of US screening data from acquisition to implementation.

What is US data? Why is it needed to acquire customers overseas?

The so-called “U.S. data” refers to U.S. mobile phone numbers (starting with +1 and related attributes) in a narrow sense. In a broad sense, it also includes the real-time status of the number - whether a certain platform has been opened, when was it online recently, the user’s gender, etc. The core of acquiring customers overseas lies in accurate reach: blindly sending invalid and inactive accounts in bulk will drive up costs and lower conversions. Therefore, having a verified resource of U.S. numbers with activity and gender tags is infrastructure for overseas marketing teams.

What types of data does the United States contain?

Type	Description
Pure number list	Only number string (starting with +1), without any verification information
Preset attribute data	Number sets exported from some platforms with some fields (such as registration time, nickname)
Real-time detection results	Perform current detection on the number through the number screening platform, and return fields such as activation status, recent online time, gender, tgid, etc.

Among them, the real-time detection results are of the highest quality because the status of the number changes dynamically. It may be activated today and may be deactivated tomorrow. The recommended approach is: first generate or import a batch of US numbers, and then perform platform screening as needed to obtain the latest status.

Key indicators of high-quality US customer acquisition data

• Opening rate: The proportion of registered numbers on the target platform. The higher the opening rate, the larger the reachable base.
• Activity rate: The proportion of numbers that have logged in/online within a specified time window (such as within 7 days). Activity rate directly affects message arrival and response rates.
• Gender Recognition: Some platforms (such as Telegram, Line) can detect users’ disclosed gender information to help with orientation.

These indicators are not fixed, and the performance of each batch of numbers will change. Therefore, regular screening of numbers is the correct approach to maintain data quality.

How to get US number data? Two ways to generate and import

To obtain the original library of US numbers, there are usually two ways:

1. Global number generation: The number screening platform (such as KK-DATA) has a built-in number generation module. You can specify the country (select United States) and number segment, and the system will randomly generate compliant +1 numbers according to the rules. This process is completely free and does not consume your balance.
2. Custom number segment import: If you have a batch of potential numbers (for example, collected from old databases or public lists), you can upload them to the console through CSV or TXT files, and the system will automatically identify and remove duplicates.

<Callout type="info" title="Generate prompts">
  Number generation is free, and testing is deducted on a per-item basis. It is recommended to use the number segment generation function to estimate the target quantity before submitting the number screening task. For the specific unit price, please see the [official website billing page](https://kkdata.cc/billing/) or the real-time price on the console.

美国数据筛号支持哪些平台？如何选择检测类型？

不同平台有不同的检测维度，你需要根据获客渠道选择对应检测类型。下面列出主流平台及其典型检测项：

平台	检测类型	典型用途
Telegram	开通/活跃/性别（含年龄字段）/tgid 导出	TG 群组冷启动、精准私信
WhatsApp	开通/活跃/性别	跨境电商私聊、社群推广
iMessage	有效号码检测	iOS 用户触达（蓝号判定）
iOS/RCS	设备可达性、RCS 开通	针对 iPhone/Android 的消息通道选择
Line	开通/活跃/性别（含男性定向）	台湾、东南亚市场
Zalo	开通/活跃/性别	越南市场特殊需求

Telegram 筛号：开通检测、活跃窗口与导出 tgid 的用途

对于 Telegram，核心操作是：

• tg开通检测：判断号码是否注册了 Telegram。未注册的号码无法被搜索或添加。
• tg活跃检测：选择活跃窗口（如 1 天内 / 7 天内 / 30 天内）。窗口越短，活跃度越高，但符合条件的号码越少。
• 性别检测：返回用户公开资料中的性别和年龄字段（如“30岁”等），可用于粗略定向。
• 导出 tgid：tgid 是 Telegram 用户的唯一内部 ID，可用于高级操作（如群组管理、脚本调用）。

WhatsApp 筛号：有效号码与活跃度判断对营销 ROI 的影响

WhatsApp 用户基数大、打开率高，但若号码未开通或用户长期离线，消息就无法送达。筛号时建议优先勾选“活跃”检测，并选择较长窗口（如30天）来平衡数量和质量。营销 ROI 公式中，活跃率≈可触达率，每提升 10% 的活跃率，同等预算下有效曝光可能翻倍。

Line & Zalo 筛号：面向特定人群的性别筛选能力

如果你的目标市场是中国台湾、日本或东南亚，Line 的性别字段很有价值——可以定向只导出“男性”用户。对于越南等 Zalo 主导市场，Zalo 筛号同样支持性别检测，帮助团队筛选出更匹配的产品受众。

如何判断美国号码是否真正活跃？活跃检测窗口该怎么选？

“活跃”是一个相对概念，筛号平台通过记录号码在目标平台的最后在线时间来判定。常见的活跃检测窗口有：

• 1 天内：极活跃用户，适合高时效性营销（如限时优惠）。
• 3 天内：较活跃用户，大部分营销场景折中选择。
• 7 天内：常规活跃窗口，平衡数量与质量。
• 30 天内：宽窗口，适合建立初始用户池或冷启动群组。

选择建议：如果你需要马上获得回复，选 1–3 天窗口，但号码量可能较少；如果是为了搭建种子用户群，30 天窗口更经济。实际项目中，可以分批多窗口检测，然后对比不同窗口的回复率，积累自己团队的数据模型。

美国数据去重为什么重要？跨任务重复扣费如何避免？

筛号是按条扣费，如果同一号码在不同任务中被重复检测，就白白浪费了余额。尤其当你多次生成或导入号码时，重复率可能高达 20%–40%。

KK-DATA 提供了数据去重仓库功能：在提交新任务前，系统会自动比对仓库中的历史记录，剔除已检测过的号码。这样：

• 避免对同一号码多次扣费
• 降低任务耗时（更少号码→更快完成）
• 不额外收费

<Callout type="warning" title="Notice">
  The deduplication function needs to be enabled in the console before submitting the task. It is recommended to check the deduplication settings every time you create a new task and make sure "Enable historical deduplication" is checked. The deduplication operation itself does not consume the balance.

美国获客数据适合哪些海外营销场景？三种典型用法

场景一：TikTok/独立站引流

利用美国号段的 WhatsApp 或 iMessage 号码，发送产品链接或折扣码，引导用户访问独立站。筛选出活跃用户后，触达成功率显著高于群发邮件。

场景二：Telegram 群组冷启动

拿到一批已开通且近 7 天活跃的美国号码后，通过 TG ID 或用户名批量拉入群组，快速积累初始成员。配合性别筛选（如面向男性群体推广游戏类群组），群内氛围更精准。

场景三：WhatsApp 私信推广

对于跨境电商，WhatsApp 是触达美国消费者的高效渠道。筛出高活跃、带性别字段的号码后，按轮次发送个性化消息（如“您的包裹有更新”），回复率可比普通群发高出数倍。

使用美国数据常见误区有哪些？如何避开数据陷阱？

误区 1：号码存在就是有效

最大误区之一。一个号码即使能拨通，也不代表它开通了你需要的社交平台。正确做法是：先筛号，再使用。

误区 2：忽视活跃度，只看开通率

开通率高（比如 80%）但活跃率低（比如 10%），意味着大量用户早已弃用该平台。建议营销预算分配前，优先较高活跃率的批次。

误区 3：忽略隐私合规

美国市场对用户隐私敏感。不要通过公开渠道大量收集未经同意的号码用于骚扰性群发。筛号平台仅检测号码自身状态，不提供用户真实姓名等隐私信息，使用数据时仍需遵守当地法规。

How to evaluate the price of American screen sizes? What kind of teams are the billing and no-subscription plans suitable for?

KK-DATA adopts the no subscription, pure payment by item model:

• Suitable for teams: studios, small and medium-sized overseas teams, and short-term project teams. No monthly commitment required, pay as you use.
• Not suitable for teams: A company that needs unlimited bulk messaging and a fixed budget? You may need to estimate the cost per task. It is recommended to test in small batches first and estimate the overall budget based on the test results.
• Price Transparency: The specific unit price of each test varies depending on the platform and test type, and is subject to the “estimated cost” before submission on the console and the official website billing page. Don’t trust any specific numbers given by unofficial sources.

Cost-effective strategy: First obtain a large number of numbers for free through global number generation, and then accurately screen out a small number of highly active and highly matched numbers for marketing, so that most invalid numbers do not incur detection fees.

FAQ

Question: Can U.S. number data be purchased off-the-shelf? Why do you recommend screening yourself?

Answer: There are indeed ready-made US number packages for sale on the market, but they often have problems such as high duplication rate (duplication from multiple sources), low activity (the data has not been updated for a long time), and obsolescence. Through the global number generation + platform number screening pipeline, the latest data verified in real time can be obtained, and the balance will be deducted based on the number of tests to avoid paying for invalid data.

Question: Is the “Gender” field of Telegram screen number accurate? Can it be used directly for orientation?

Answer: The gender field comes from the user’s public information and is not accurate at the ID card level, but it can be used as an auxiliary targeting dimension in batch screening. Some tests also include an age field, which can be used to screen people around 30 years old and other rough targeting, and cannot replace accurate user portraits.

Question: How many numbers can be submitted at one time for US data screening? Are there any restrictions?

A: A maximum of approximately 1 million numbers can be submitted for a single task (this may vary slightly depending on the platform and detection type). The console will display the estimated fee before submission, and you can submit if you have sufficient balance.

Question: If the balance is not used up, can it be refunded?

Answer: The deposit is in USDT (TRC20), with a minimum of about 50 USDT. After the balance is charged, it will be used for testing and deduction, and cannot be returned in the same way. It is recommended to recharge in batches according to the actual task volume to avoid large hoarding.

Q: What is the difference between iOS/iMessage detection and normal WhatsApp detection?

Answer: iOS detection is used to identify whether the device is reachable (similar to blue number, iMessage is reachable), iMessage detection is used to determine whether iMessage messages can be received; WhatsApp detection mainly determines whether the number has activated WhatsApp and the most recent online time. The two target different reach channels and can be used together.
