SOP for the whole process of US ws number delivery: How to efficiently screen and accept numbers in studio operations

For overseas operation teams and studios, US ws number (i.e. US WhatsApp activated/active number) is the core asset for private message access, community operations and cross-border e-commerce promotion. However, many teams frequently encounter problems such as missed screening, repeated testing, and inconsistent delivery standards during batch delivery: the same batch of numbers have conflicting active statuses in different batches, customer complaints continue, and funds are wasted on repeated deductions.

Standardized operating procedures (SOP) can effectively solve these pain points. This article is based on the KK-DATA platform, sorting out the complete SOP from number generation, screening, deduplication to acceptance, helping the studio deliver high-quality US WhatsApp numbers at the minimum cost.

What is a US WS number? Why do studios need standardized SOPs?

US ws number refers to a US mobile phone number that has been verified by the WhatsApp platform and confirmed to be registered or active. The key difference between it and ordinary US mobile phone numbers is that ordinary numbers may not be registered with WhatsApp or have expired and cannot be used for marketing; while ws numbers have gone through “activation detection” or “activity detection” and can be used for subsequent private messages, group recruitment and other operations.

Common application scenarios of US ws numbers

Telegram/WhatsApp community operation: Use verified US ws numbers to invite users to join the group in batches to reduce the risk of account bans.
B2B private message promotion: targeted reaching out to US cross-border e-commerce sellers and independent website customers.
Customer Contact and Customer Service: Provide real WhatsApp contact channels for overseas stores to increase response rates.

Common pain points without SOP: missed screening, repeated testing, inconsistent delivery

Pain points	Manifestations	Consequences
Missing the screen	Only part of the same batch number has been tested for activation, and active data is missing	The numbers delivered to customers are mixed with invalid numbers, affecting the effect
Duplicate testing	The same number is repeatedly screened in different batches	The balance is wasted and the budget is exceeded
Inconsistent delivery	Different standards for the active window (such as 30 days vs 90 days) of the two batches of numbers	Customers cannot compare data and their trust is reduced

Standardized SOPs can uniformly generate rules, screening parameters and acceptance fields, allowing the team to “get it right the first time” and avoid rework.

How to efficiently generate a US WhatsApp number (US WA number)?

Generating a number is the first step of the SOP and does not consume your balance. In the KK-DATA console, there are two mainstream methods:

Randomly generated by country/region: suitable for quickly obtaining a general population

Log in to Application Console and enter “Number Generation”.
Select the country “United States” and set the required number of numbers (for example, 10,000).
Click “Generate” to get a batch of random US segment numbers.
Multiple batches can be generated repeatedly for subsequent screening.

This method is fast and suitable for scenarios that require a large number of basic numbers for activity screening.

Import by number segment or customized CSV: suitable for precise targeting areas

If the customer requires a specific city or area code (such as Los Angeles 213, New York 212), the number segment can be used to generate it:

Enter “213” as the prefix in the generation module to specify the number of digits and quantity.
The system will automatically complete the number based on the US number segment rules.

If you already have your own number list (such as leads collected from other channels), you can also upload it directly through CSV Import. After importing, these numbers will enter the “number database to be screened” and the screening task can then be submitted. This method ensures source control and is especially suitable for maintaining old customer databases.

How to set the core parameters of US WS number screening: activation, activity, and gender?

Screening is the key to turning “potential numbers” into “high value numbers”. In KK-DATA, each screening task requires the selection of detection items, and billing is deducted on a per-item basis (see the real-time price on the console for specific unit prices).

Selection of opening detection and activity windows

Activation detection (switch detection): Confirm whether the number has been registered with WhatsApp. This is a basic item and must be checked.
Activity Detection: Based on public data, determine whether the number has been active in the past N days. You can choose a window (e.g. 30 days, 90 days, 180 days). If the customer requires recent active users (such as login in the past 30 days), check “Active” and specify the window; if the user only needs to be active but does not need to be active, just enable detection.

Recommendation: Do the activation test first, and then do the activity test on the activated number. You can submit it in batches to reduce initial costs.

Use of Gender Fields in Studio Delivery

KK-DATA’s gender detection will return probability analysis results (not 100% accurate), including gender, age and other fields. For example, screening US WS numbers with “male proportion ≥70%” can be used in marketing scenarios for male users. The age field can assist in interpreting the target group (for example, focusing on screening for the “about 30 years old” age group), but please note that age judgment is based on an algorithm model and is not accurate at the ID card level.

In the delivery acceptance form, you can use the “Gender” field as an optional dimension to clearly inform customers that this is a probabilistic identification and is for reference only.

What fields should be included in the acceptance form in the agent operation SOP?

The standard acceptance form (CSV/Excel format) can be used directly by customers. It is recommended to include the following columns:

Field	Description	Example
Number	Complete mobile phone number (including country code)	+12025551234
Platform	Pinned to “WhatsApp”	WhatsApp
Activation status	true/false	true
Active time window	Last 30 days/Last 90 days/unknown	Last 30 days
Gender (probability)	Male/Female/Unknown	Male
Export batch	This task batch ID	batch-2025-01-01
First detection time	Screening completion time	2025-01-01 10:00:00

In KK-DATA, you can customize columns when exporting, export CSV/TXT at once, and directly map it to an acceptance table. It is recommended to check the fields such as “Activation Status”, “Active Days”, and “Gender”.

How to design re-screening rules to avoid repeated deductions?

Many studios will re-screen the same batch of numbers on a regular basis (such as every month) to ensure that activity is up to date. If deduplication is not performed, all numbers will be re-billed for each screening, resulting in waste.

KK-DATA provides data deduplication warehouse function:

After the first filtering, export the results and mark them as “processed”.
During the next re-screening, first import the new batch number (or updated batch) into the deduplication warehouse.
The system automatically eliminates numbers that have been detected (based on number hash deduplication), and only charges for new numbers or numbers that need to be updated with detection items.

Note: By default, the deduplication warehouse retains all fields detected for the first time. If you need to add new fields such as “Gender” or “Active Window” in the future, you can check “Recheck only for missing fields” in the warehouse to avoid repeated billing for numbers that already have fields.

For specific setting methods, see Usage Documentation.

Full practical process: 5-step pipeline from generation to delivery

The following is a standardized 5-step process for studios that teams are encouraged to follow:

Generate numbers → Generate by country/area code in the console or import by CSV (free).
Duplicate Warehouse → Import the numbers to be screened into the warehouse and remove the historical detected numbers (to avoid repeated deductions).
Set filtering parameters → Check enabled detection, active window (such as 30 days), gender (optional), and submit the task.
Export results → After the task is completed, export CSV/TXT, including the fields required for acceptance.
Acceptance and Delivery → Organize the data according to the acceptance form template and send the file to the customer.

The entire process is operated visually and no programming is required. A single task supports up to about 1 million numbers, but it is recommended that each batch be controlled within 100,000 to facilitate quick export and verification.

Tip: Free to generate, screen numbers are charged per item

The generation of all numbers does not consume any balance, and will only be billed based on the number of detections after the screening task is submitted. It is recommended to generate a list to be screened first, and then use the deduplication warehouse to import it to avoid wasting budget on repeated testing.

Suggestion: Make good use of export templates to reduce manual editing

Columns (such as tgid, wsid, active days, etc.) can be customized when exporting in the console, and can be mapped to an acceptance table once exported. Use it directly after exporting, no need for secondary cleaning.

FAQ

**Q: What is the difference between a US WS number and an ordinary US mobile phone number? ** Answer: The US WS number refers to the US mobile phone number that has been verified by the WhatsApp platform and confirmed to be registered or active. Ordinary US mobile phone numbers may not be registered with WhatsApp, or may have expired, and cannot be used directly for WhatsApp marketing.

**Q: How to ensure that the filtered US WS numbers are highly active? ** Answer: Set the active window in the filtering task (such as “Activity in the past 90 days”) and select the “Active Detection” item. KK-DATA will return active flags based on WhatsApp public behavior data. It is recommended to check “Enable Detection” at the same time to confirm that the number is valid.

**Q: How many US WS numbers can the studio screen at one time? ** Answer: KK-DATA supports a maximum of about 1 million numbers in a single task, but the actual number is limited by account balance and network concurrency. It is recommended to submit in batches, with each batch limited to 100,000 entries to facilitate verification and export.

**Q: Can the filtered US wa number be used repeatedly? ** Answer: Yes. However, the active status of the number will change according to the usage habits of the other party. It is recommended to re-screen before each marketing (use the deduplication warehouse to skip the checked numbers, and only pay for new numbers or regularly updated batches). Avoid waste caused by repeated testing of different batches.

**Q: How can a studio without programming foundation get started? ** Answer: KK-DATA provides a visual console, and all operations are point-and-click. Just follow the sequence of “Generate→Deduplicate→Filter→Export”. Documentation (https://docs.kkdata.cc/）有图文指南，也可通过Telegram客服获得一对一协助。
