Practical plan for screening US mobile phone numbers: supporting operator, format, and country identification

In global customer acquisition, social account building, SMS marketing implementation and other businesses, the quality of mobile phone numbers directly determines conversion efficiency. The U.S. market has become a key area for companies to screen numbers due to its diverse operator structure and highly active social ecology. However, many companies face the following common problems when importing U.S. mobile phone number data:

lThe format is not standard, resulting in registration failure or platform rejection.

lThere are too many virtual accounts, causing SMS messages to bounce or fail to be delivered.

lNumber ownership is unclear and data compliance is limited

lCountry identification error affects the accuracy of delivery area

To completely solve these problems, it is necessary to adopt a set ofOperator identification, format specification detection, and country ownership judgmentComplete screening process for the three major competencies. Below, we will dismantle the standard screening logic and combine it with the automation tools of the Digital Planet platform to introduce a set of practical and implementable efficient solutions.

Core Issue 1: Number formats are diverse and cleaning is difficult

Although the U.S. number structure appears to be uniform (usually10 digits + country code 1), but there are many variations hidden in actual use:

lSomeone mixed it in when importing+1 prefix, some people don’t have it

lSomeone added area code brackets (e.g.(213)1234567), some have no delimiter

lSome contain spaces, dashes, and illegal characters.

lSome imported data also contains non-U.S. numbers.

These minor format problems will directly lead to the rejection of the registration interface, the failure of the SMS platform to send, and even affect the success rate of account verification.

Therefore, the first step must be to use a unified format verification mechanism to automatically clean the imported numbers, remove invalid data and illegal characters, and ensure that all numbers are uniformly formatted into international standard forms (such as:+12135551234).

Core Problem 2: The type of operator is unknown, which can easily trigger risk control

The continental United States has more than50 operators, among which mainstream physical card operators such as Verizon, T-Mobile, and AT&T, occupy high-quality number segments. Although the T-card number segments provided by a large number of virtual operators (VoIP), such as Google Voice, TextNow, Ultra Mobile, and Mint Mobile, are in compliance with the format, they have the following problems:

lEasily tagged by social platforms"Low credibility account"

lAlthough registration was successful, login and secondary verification frequently failed.

lThe number life cycle is short and the account cannot be maintained for a long time.

lThe failure rate of sending text messages is high, and the information cannot reach users.

These problems often cannot be solved through format judgment and must beOperator ownership identificationto determine its availability.

Core Issue 3: Wrong country identification, affecting distribution areas

When many teams use U.S. mobile phone numbers, they mix similar number segments from multiple regions around the world. For example, Canadian numbers have a similar structure to those of the United States, and the area codes overlap. Once the recognition is wrong:

lIt may cause the target launch to deviate from the market and waste the budget.

lPlatform prompts when registering"Non-U.S. users" cannot enjoy local rights and interests

lPush language and event content mismatch, affecting user acceptance

Therefore, it is necessary to include in the filterThe "national identification" mechanism ensures that the number accurately matches the country location.

How does Digital Planet solve the above three major problems?

In order to solve the core challenges encountered in batch screening of U.S. mobile phone numbers, Digital Planet has built an automated screening system based on intelligent identification and operator databases, covering three major capability modules:

1. Format specification recognition system

lAutomatically identify country code+1 starting format

lEliminate illegal symbols, letters, short numbers, and repeated numbers

lStandardize all numbers into a unified format and adapt to various platform interfaces

lSupport fromImport numbers in batches in CSV, TXT, XLS and other formats

2. Operator type judgment system

lQuickly check the operator of the number

lDistinguish between physical cards and virtual cards (T card), automatic marking

lProvide virtual account usage risk level scoring to assist in screening strategies

lUpdate local carrier paragraphs in the United States in real time to prevent misjudgments due to data lag.

3. National belonging detection capabilities

lIdentifies whether the number belongs to the United States based on the number range

lAutomatically eliminate non-US area numbers or locate incorrect numbers

lSupports mixed cleaning of international data to avoid incorrect use of code segments from neighboring countries such as Canada and Mexico.

A practical guide to the screening process (can be used even if you don’t have a technical background)

The following is the standard process for completing US carrier screening using Digital Planet:

Step 1: Register and log in to the platform

Visit the official website of Digital Planet and complete the corporate account registration. There is no need to deploy programs, the platform is ready to use.

Step 2: Upload the original number file

Platform supportExcel, CSV, TXT and other formats support millions of imports without preprocessing.

Step 3: Select filter dimensions

Users can choose filtering targets independently, such as:

lKeep physical card carrier

lCullVoIP passage

lLimited US area numbers+1 format

lCheck format legality

Step 4: Generate screening report with one click

The system automatically identifies the operator, format, and country and outputs a structured report (CSV/JSON), can be used directly for importing systems or distribution tasks.

Practical application scenarios cover the entire industry

The following industries are typical users of U.S. number screening:

Cross-border social registration company

for bulk registrationAccounts such as WhatsApp, Telegram, and LINE need to avoid the risk of account suspension.

Global SMS service provider

Clean virtual number segments, improve verification code delivery rate, and reduce SMS bounce costs.

E-commerceSaaS platform

Automatically screen numbers during the customer introduction phase to eliminate invalid and abnormal numbers to improve user system stability.

Overseas private community operators

Build an accurate user pool to avoid introducing a large number of virtual accounts, resulting in unread messages and low conversions.

Advertising and lead purchasing platform

Identify the mobile phone number before launching, accurately target US users, and improveROI.
