Building a U.S. mobile phone number pool with stable registration and reachable text messages: Practical Guide for Operator Number Segment Screening

In cross-border social operations, international SMS delivery andIn scenarios such as CRM user management, a seemingly basic problem is becoming a key bottleneck——How to build a stable, registerable, and accessible U.S. mobile phone number pool?

You may have experienced the following dilemmas:

lThe format is clearly compliant and registered.WhatsApp or Telegram frequently fails

lThe social account was successfully registered, but was banned by the platform in a short period of time.

lAfter sending a large number of text messages, a large number of receipts are displayed"Not delivered" or "Invalid number"

lCustomer number importUnable to interact after CRM, affecting SCRM policy execution

Behind these problems, it is often not"There are not enough numbers", but "there is no systematic operator screening and number segment risk identification".

This article will explain in detail the correct method to build a high-quality U.S. mobile phone number pool, share practical tips for number segment screening, and introduce how to passDigital Planet PlatformRealize intelligent processing of the entire process from import to output.

What kind of U.S. number counts?"high quality"?

An ideal U.S. mobile phone number should meet the following conditions at the same time:

1.Format standards: Conforms to international formats (Starting with +1, 10-digit number structure)

2.Belongs to a local US operator: Avoid blending into Canada/Puerto Rico/Caribbean and other similar number segments

3.Belong to the physical card operator:likeAT&T, Verizon, T-Mobile, strong stability and long-term use

4.Non-virtual number segment: EliminateGoogle Voice, TextNow, Ultra Mobile and other high risk control number segments

5.Strong ability to send and receive text messages: Verification code can be received normally/Marketing notifications, do not block international text messages

6.Good historical usage: The number segment is not widely used for batch registration or code receiving services.

As long as the above conditions are met, this number can basically be used for: registering social accounts, building a stable customer pool, executing international SMS delivery, and dockingSCRM system and other operations.

Create a mobile phone number poolThree major sources of “pollution”

1. Mixing of virtual operator numbers

Excessively high proportion of VoIP segment numbers (such as Google Voice, TextNow) will lead to an increase in registration failure rate, soaring SMS non-delivery rate, and short account retention time.

2. The number structure in non-US areas is confusing

Some data collection or third-party number sources contain non-U.S. number segments (such as Canada+1 area code, shared number segment in the Caribbean) were mixed in, resulting in biased regional judgment and the registration channel was mistakenly rejected.

3. Segments with severe risk control have not been processed

Some number segments have been included in the risk list by social platforms due to being contaminated by a large number of code reception and registration activities. Even if they belong to physical operators, they have also been included in the risk list."Continuous sitting" is marked as a suspicious number segment.

Five major processes for building a high-quality mobile phone number pool

To completely solve these problems, a mobile phone number pool must be established through a systematic process:

Step 1: Import original number data

Includes all available U.S. mobile phone number sources, such as self-collection, platform collection, user retention,Lead buying volume, etc., the import format can be TXT, CSV, Excel format.

Step 2: Format standardization

lComplete the country code (unified as+1)

lEliminate illegal characters, spaces, and short symbols

lDeduplication to ensure no duplicate numbers waste resources

lOutput a unified standard format and adapt toAPI and registration system

Step Three: Operator Attribution Identification

The system determines which operator each number belongs to, including:

lMain Operator (AT&T, T-Mobile, Verizon)

lVirtual Operator (TextNow, Mint Mobile, Tracfone)

lMVNO mixed virtual and real paragraphs (Ultra Mobile, Simple Mobile)

And label them for easy screening and use in the next step.

Step 4: Score the risk level of the number segment

Based on historical registration success rate, SMS delivery status, platform risk control frequency,VoIP segment ownership, etc., the risk level of each segment is assessed and scored automatically.

Step 5: Export the high availability number pool

Export the target number pool according to the filtering strategy, such as:

lOnly physical card segments are retained

lEliminate high riskVoIP number segment

lKeep numbers with high SMS reachability rates

lFilter available paragraphs based on platform registration requirements
