International mobile phone number test, which overseas numbers are worth continuing to use?

Duplicate numbers, missing area codes, mixed local and international formats,Excel changed the numbers to scientific notation, and the historical numbers from a few years ago have not been rearranged. These problems are not obvious in hundreds of pieces of data. Once the numbers increase to tens of thousands or hundreds of thousands, subsequent screening and marketing will be affected.

Therefore, international mobile phone number testing is not just about checking whether there is any problem with the number. A more practical idea is to sort out the underlying data of overseas numbers first, and then continue to screen based on actual business.Social accounts such as WhatsApp, Telegram, LINE, and Zalo. The number layer should be clear first, and then the subsequent customer data will be really useful.

Data from multiple countries are mixed together. First, separate the countries clearly.

The first thing to deal with overseas numbers is usually not the social account, but the country and region.

The United States, the United Kingdom, Japan, Thailand, Vietnam, Singapore and other markets have their own country codes and numbering rules. If some of the original data have already used international formats and some are still local numbers, it is easy to cause recognition errors after direct merging.

If the original country information already exists, it is best to keep it.

In this way, whether it is to check the basic status of the number or enterBy screening on WhatsApp, Telegram and other platforms, you can know which market this data belongs to.

For those who have been developing customers in multiple countries for a long time, once the country information is lost, rearranging it later will be much more troublesome than processing it the first time.

International area codes are not uniform, and it is easy to mistake normal numbers for abnormal data.

If the same mobile phone number is written in different ways, the system may see two completely different data.

For example, one file already contains the country code, and the other file only saves the local number. After the two data are merged, if the format is not unified first, deduplication and detection will be affected.

Therefore, before international numbers enter batch testing, you can check:

lIs the country code missing?

lDoes the local number need to be converted into international format?

lAre numbers written in the same country consistent?

lIs there any obvious abnormality in the number of digits?

lHas the original mobile phone number been modified by file software?

After these basic issues are dealt with, it will be more accurate to judge the number status.

Clearing out duplicate numbers first is easier than repeating the test later.

Overseas customer data often comes from multiple portals.

A customer may have left a number in the advertising form, later consulted the website, and then entered the system through customer service. After merging several files, it is normal for the same mobile phone number to appear two or three times.

If duplication is not removed first, the same piece of data will be processed repeatedly when checking international mobile phone numbers later.

After entering the social platform screening, it will be repeated again.

Therefore, when the number of numbers is relatively large, the first round of cleaning can first process the completely duplicate data while retaining valuable source, product and historical information.

The ultimate goal is not just to reduce the number of file lines, but to allow one customer to correspond to a clear main number record as much as possible.

Normal numbers in Excel may also be processed into incorrect formats

The international mobile phone number is relatively long, so just put it inAfter Excel, scientific notation often appears.

After some files have been copied, exported and re-saved many times, the numbers are not even completely consistent with the original data.

This type of problem is particularly likely to appear in historical customer files.

Therefore, before testing, it is best to confirm whether the mobile phone number list is complete text and whether the number has been automatically truncated or the display mode has been changed.

For a lot of seemingly unrecognizable data, the real problem is not the number itself, but that the file format has changed.

Overseas numbers must go through a basic test first, and it will be much easier to screen social accounts later.

Digital Planet can undertake related detection of international mobile phone numbers and subsequent screening of social platforms.

After the number sorting is completed, you can further check the number's basic status, ownership information, etc., and then continue to enter different platforms according to specific services.

If the main passWhatsApp development customers can continue to screen the WhatsApp activation status; those who mainly operate Telegram can further confirm the TG account and check the relevant active status as needed; LINE markets such as Japan and Thailand can continue to screen the LINE account; Vietnamese customers can further conduct Zalo related tests.

Such an overseas number does not need to be mixed together to check all the information at once, but the number itself is first solved, and then the specific social channels are solved.

Do not confuse your normal mobile phone number with your registered social account number.

This is a particularly common misunderstanding in international mobile phone number detection.

Just because a number is in normal use does not mean that it must be activatedWhatsApp.

Similarly, it cannot be because it is not detectedTelegram, LINE or Zalo account will directly determine that the mobile phone number is invalid.

The number status belongs to the mobile phone number itself.

The activation status of social platforms belongs to the account level.

Therefore, when actually organizing customer data, you can first screen out the basic numbers, and then continue to detect according to the platform you are currently planning to use.

In this way, when you see a certain piece of data later, you can know whether there is a problem with the number itself, or whether it is just that the current target social platform has not been opened.

Historical overseas numbers, most worth re-checking

Newly acquired data is usually easier to sort through, but the real trouble is with historical numbers.

Mobile phone numbers saved a few months ago or even one or two years ago may have been merged, deduplicated, and re-exported many times, and the number status may also have changed.

When preparing to restart a certain country's market, you can first reorganize the historical data.

Duplicate numbers are processed first, the format is reunified, and then the basic information of the number is updated through Digital Planet, and then filtered according to the current marketing channel.WhatsApp, Telegram, LINE and other accounts.

In this way, the old data is not taken out and used again directly, but updated first and then re-entered into the current business process.

After testing, which numbers are more worth continuing to use?

Whether a number is worth continuing to use cannot be judged by just one result.

The most basic layer is that the number format is normal, the country information is clear, and the conditions are currently met to proceed to the next step.

Next, we have to look at the actual marketing channels.

If the customer mainly passesFor WhatsApp communication, continue to look at the basics of WhatsApp accounts; if you are planning to do TG promotion, then look at Telegram activation and account status.

If the original customer information also contains information such as advertising sources, product categories, historical transactions, etc., these should also be retained together.

This business information determines what content is suitable for customers to receive later, and number detection is responsible for sorting out the contact information first.

The international number database should not only be in but not out

The problem with many number databases is not that there is too little data, but that new numbers are constantly being added over the years but rarely re-cleaned.

As time goes by, there are more and more duplicate items, the old format becomes more and more messy, and the historical state becomes less and less suitable for current use.

A more practical way is to do an overall reorganization after restarting a certain market, preparing for a new round of large-scale marketing, or after the customer base has accumulated to a certain number.

Go through the basics of repetition, format, country and number again, and then enter the social platform detection that is really needed at the moment.

In this way, the customer database will be continuously updated, instead of growing larger and more chaotic.

Clean the number first, then talk about the platform

The most practical process for international mobile phone number detection is actually very simple.

First divide the countries, unify the international dial codes, deal with duplication and format abnormalities, and then check the basic situation of the numbers through Digital Planet. After sorting out the underlying numbers, we can useActual channels such as WhatsApp, Telegram, LINE, and Zalo continue to screen.

The number must be clean first, and then we can talk about the platform; the platform must be screened first, and then we can talk about marketing.

In this way, a large number of overseas mobile phone numbers are not a bunch of data that seems to be a lot, but a real customer number library that can continue to be used.
