How to filter valid international SMS numbers? The fastest and most stable practical solution

International SMS is one of the most commonly used notification and marketing channels for cross-border enterprises. Although it has wide coverage and fast reach, there is also a core issue that has been ignored for a long time.——The validity of the number is unclear, resulting in a large number of text messages being sent in vain but no response received.. Many companies do not screen before sending global text messages. What they end up with is a high bounce rate, high delivery costs, and low conversion rates, which seriously affects delivery.ROI.

So, how to efficiently filter out valid international SMS numbers? Is there a quick and stable practical plan? This article will explain it to you in detail.

What are valid international SMS numbers? Why is screening necessary?

A "valid number" doesn't just mean a "correctly formatted" number, it means:

lThe number is real and has not been canceled

lCurrently in a state that can receive text messages (not powered off, not virtual number)

lCountry of origin and operator are true and accurate

lNot marked as rejected or blacklisted SMS users

especially while doingHigh frequency notification text messages,Verification code issuance,Cross-border marketing promotionWhen waiting for the launch action, if invalid numbers are not screened out in advance, the budget will be wasted at best, and the risk control of the platform will be at worst.

Key steps to filter valid international SMS numbers

1. Get the original number list

Businesses typically obtain international numbers from the following sources:

lCRM customer data export

lLead acquisition in the marketing funnel

lsocial platforms (such asWhatsApp, Telegram, LINE) user records

lObtain through offline activities or public account channels

The format of these numbers may not be uniform, and the country code may be missing, garbled, or repeated, so the first step must beStandardization.

2. Use the detection system to identify the number status

The core of screening is not manual verification, but the use ofIntelligent number detection system, such as Digital Planet, performs batch processing and can identify the following states at one time:

lIs it a real mobile phone number?

lHave you registered with the operator system?

lIs it currently powered on?

lWhether to adapt to SMS channels (excluding virtual numbers)

lWhether it is in the SMS blacklist or outage state

Through this process, you can directly eliminate:

lnon-existent number

lTemporary, shared, SMS interception virtual account

lShutdown times out or the number is not online for a long time

lRepeated and abnormally formatted numbers

3. Export “sendable numbers” in batches

After the screening is completed, the platform will automatically classify"Number that can be sent" and "Number that cannot be sent". Enterprises only need to export the available number part with one click, which can be used on the SMS delivery platform, greatly improving the delivery rate and reach effect.

Case scenario: Screening process before launching on SMS platform

Assume that a company is preparing toPotential user groups in 10 countriesMass text messages for new product launches include multi-lingual versions in English, Arabic, and French. If launched directly in full volume, the losses may be huge. At this time, the operation of using Digital Planet is as follows:

1.Import number list(The system automatically identifies the country and format)

2.Select detection type(Including whether it is turned on, whether it is adapted to the SMS channel, and whether it is a real number)

3.Automatically detect and classify results(efficient/invalid/empty number/virtual number)

4.Export available numbers(Uniform format, can be directly connected to the SMS platform)

After the test was completed, the company found that the original number contained27% had empty numbers or could not receive text messages. After timely screening, nearly 30% of text message fees were saved and the delivery rate was greatly improved.

What are the consequences of not screening?

Many companies mistakenly believe that the more numbers, the better, and the faster they are delivered, the more effective they are. But the fact is:

lA high bounce rate after SMS delivery will result in the platform blocking your account or deducting credit points.

lIf the same user cannot receive text messages, he may miss business opportunities or complain about service quality.

lCluttered data will slow down the entire marketing rhythm and increase customer service pressure.

therefore,The starting point of text message delivery is not to write copywriting or design channels, but to detect which numbers are worth sending.
