Batch identification of US carrier number segments: adapted to registration, marketing and SMS scenarios

In the global communication system, the mobile phone number structure in the United States seems to be unified, but in fact it is complex. Whether it is batch registration on social platforms, sending marketing text messages, or building private domains for overseas brands, accurate identificationTypes of carriers behind U.S. mobile phone numbers, is always the basis for data cleaning and delivery.

Especially in a batch operation environment, once a large number of virtual operator numbers are mixed in, it may not only cause registration failure and SMS delivery failure, but also affect the long-term stability of account maintenance and user contact. This article dismantles the systemHow to efficiently identify US carrier number segments, and introduced how to use the digital planet platform to achieve automated screening, cost reduction and efficiency improvement.

Why do U.S. mobile phone numbers need carrier identification?

Local numbers in the United States are fixed10-digit structure, but the "availability" of the number depends entirely on the operator behind it. These operators can be roughly divided into two categories:

1. Physical operators (mainstream operators)

likeAT&T, Verizon, T-Mobile, etc. are traditional SIM card service providers. Their numbers are stable, support registration, receive text messages, and remain active for a long time.

2. Virtual operators (VoIP, MVNO)

likeThe numbers of Google Voice, TextNow, Mint Mobile, Ultra Mobile, etc. are mostly Internet calling (VoIP) or short-cycle packages. They are often used for code receiving platforms, batch registration, and temporary purposes. They are prone to invalidation or being flagged by the risk control system.

If you are doing the following types of operations, carrier screening is almost a required step:

lSocial platform registration account pool (Telegram, WhatsApp, iMessage, etc.)

lInternational SMS sending list cleaning

lCustomer mobile phone number entryCRM or SCRM system

lCustomer introduction and stratification of private community

lFalse registration detection in anti-cheating scenarios

The risks of virtual accounts are far greater than they appear

Many people mistakenly think"If the number can be connected, it means there is no problem." However, in enterprise-level applications, the problem of virtual operator number segments is particularly serious:

lLow SMS delivery rate: Some SMS gateways will automatically block virtual numbers or mark them as risky numbers

lHigh registration failure rate: Some platforms (such asFacebook, Amazon) have strict restrictions on VoIP number ranges

lshort life cycle:T-cards often expire within a few days or weeks, and account maintenance costs are high and results are easily lost.

lAccount is easy to close: Once the platform identifies the source of virtual cards registered in batches, the account will most likely be blocked.

Therefore, number screening down to the operator level is a key link to ensure the stability and sustainability of the project.

How to identify and screen US carriers?

Operators who identify U.S. mobile phone numbers have traditionally relied on public number segment ownership documents or crawler services. The disadvantages are:

lData lags and number segment updates are not timely

lManual downloading and maintenance of operator mapping table is required

lLack of structured output and inability to batch process

lUnable to determine the risk level of virtual numbers and number segments

In order to improve recognition efficiency and accuracy, it is recommended to use automated tools for processing. Taking Digital Planet as an example, the platform has established a completeUS Cell Phone Number Carrier Identification System, with the following capabilities:

Core screening capabilities of Digital Planet Platform

As a one-stop number detection platform, Digital Planet supportsworldwide190+ countriesIt performs format identification, status detection and operator identification on mobile phone numbers, especially in terms of US operator screening, with the following key functions:

1. Automatically identify the operator to which the number belongs

Upload any batch of US numbers, and the system will automatically output the corresponding operator attribution, such as:

lVerizon Wireless

lAT&T Mobility

lT-Mobile USA

lGoogle Voice

lTextNow

lMetroPCS etc.

And simultaneously mark the differences between mainstream operators and virtual operators.

2. Structured output of virtual number identification tags

Not only the operator name is provided, but also based on historical usage and risk determination,The suggested tag of "whether it is a virtual number" facilitates direct filtering or tag processing in the business.

3. One-click batch processing + supports global formats

Digital Planet supports uploading millions of numbers in batches, producing results within minutes, and supports intelligent identification of global formats, including the United States, without the need for country-by-country processing.

4. Does not rely on local scripts and maintenance

There is no need to configure localized crawler scripts or manually maintain the number segment table. You only need to register and log in to the platform, import the number to use the complete detection service, and the results can be exportedCSV/JSON format is connected to the back-end system.

Why is Digital Planet recommended?

Although there are other third-party tools or self-built solutions on the market, Digital Planet has obvious advantages in terms of data integrity, recognition accuracy and ease of use:

lData updated in real time, covering mainstream and niche operator account segments

lNo need to write code, low operating threshold, suitable for use by non-technical teams

lSupport global numbers, not limited to the United States, can expand the scope of application

lStructured report export, to facilitate system docking, customer delivery, and team transfer
