How to do number quality testing? How to filter invalid data from a large number of overseas mobile phone numbers

As cross-border marketing enters the digital operation stage, companies accumulate more and more overseas mobile phone numbers, and data quality problems are also magnified. Numbers brought from official website forms, advertising leads, exhibition lists, historical orders, and cooperation channels often have inconsistent formats, missing country codes, duplicate saves, long-term failure to update, and inability to be reached through target platforms. The value of number quality inspection is to determine which data is worth continuing to use and which data needs to be corrected or eliminated before sales start contacting them, and then classify them based on country, source and social platform, so that the originally chaotic number list can be turned into a customer list that can be directly executed.

The large number of numbers does not mean there are many marketing resources.

Many companies regard the number of numbers as the size of their customer resources, but of a table containing 100,000 records, only part of it may actually be used. Some numbers come from repeated submissions, and the same customer has been saved multiple times; some numbers lack international area codes and cannot correctly identify the country; and some numbers, although in normal format, are no longer usable, or have not been opened for use by the enterprise.WhatsApp, Telegram, LINE and other platforms.

If these problems are not dealt with in the early stage, they will all enter the sales process. Sales staff need to add items one by one, send them one by one, and record the reasons for failure one by one. This not only wastes time, but also affects the team's judgment on market effects. The low response rate in a certain country may not mean that there is no demand from local customers, or it may be that the proportion of invalid data in the list is too high.

Therefore, number quality inspection is not simply to check whether the mobile phone number can be dialed, but to evaluate whether the entire batch of data has subsequent marketing value.

What are the main aspects of number quality?

First you need to check the number format. Different countries have different mobile phone number lengths, country codes, and writing habits. Common problems in the data include missing area codes, repeated area codes, inclusion of spaces or symbols, and the mixing of local and international formats. Format errors will affect system recognition and lead to inaccurate subsequent platform detection results.

Secondly, duplicate data needs to be processed. The same user may leave contact information through multiple channels such as advertisements, official websites, and exhibitions. If the company does not remove duplicates in a unified manner, the customer may be contacted repeatedly by different salesmen. Duplicate data not only increases workload, but also easily affects customer experience.

Once again, you need to confirm whether the number meets the usage requirements of the target channel. Businesses are ready to doFor WhatsApp marketing, you need to first determine whether the number is enabled for WhatsApp; when preparing for Telegram intensive chat, you need to select numbers with basic Telegram reach; when developing the Japanese market, you must also consider whether users use LINE. The number itself is valid and does not mean it is suitable for all marketing platforms.

Finally, combine data sources and customer tags. If a valid number has an unknown source and no authorization record, it is not suitable for direct promotion; a user who has opened a social platform cannot be considered a high-quality customer if it has nothing to do with the company's target industry.

Number quality inspection should be placed at the front of the marketing process

A more reasonable data processing process is for enterprises to first summarize the numbers obtained through normal business channels, then complete format unification, country identification and duplicate data cleaning, then detect corresponding social platforms based on marketing goals, and finally classify them according to country, source, product direction and customer stage.

For example, if a company is planning to develop the European, Southeast Asian and Japanese markets at the same time, it can first organize the numbers by country and then filter out suitable ones.Users who communicate on WhatsApp, Telegram or LINE. The list obtained by the sales team already has basic region and channel labels, and there is no need to try one by one from a large amount of raw data.

Although this reduces the number of numbers that ultimately enter the sales process, it can increase the actual usable ratio. What enterprises need is not a seemingly large list, but a batch of customer data that can explain the source, confirm the channel, and suit the current business direction.

How Digital Planet helps enterprises complete batch number screening

When the number scale reaches tens of thousands or more, relying on manual inspection is inefficient. Digital Planet can be used to sort out the existing numbers of the company in the early stage, and help the team to filter by batch testing the opening status of the social platforms corresponding to the numbers.Target platform users such as WhatsApp, Telegram, LINE, etc., while filtering duplicate and partially invalid data.

For example, the company sorted out 50,000 overseas numbers from official website inquiries, advertising forms and historical orders, and prepared them throughWhatsApp development client. You can first use Digital Planet to screen numbers that have opened WhatsApp, then split the list according to country, and hand it over to sales in different regions to continue to determine the customer's industry and intention. In this way, Digital Planet solves "which numbers have the basis for reaching the target platform", and the sales team continues to solve "which users are in line with the product direction, how to communicate and whether they are worthy of long-term follow-up".

It should be noted that the number detection tool cannot directly turn ordinary numbers into accurate buyers. Test results must be combined with data sources, customer needs and sales feedback to truly judge number quality.

After the detection is completed, customer data must be continuously updated.

Number quality is not fixed. Customers may change their numbers, stop using a certain platform, or may have no demand during the first contact and later develop new purchase plans. After the company completes a test, it needs to re-record the sales communication results into the customer database.

Users who can be contacted but have no need for the time being can enter the long-term follow-up list; data with invalid numbers or users who explicitly refuse to contact should be stopped in time; customers who have already communicated need to supplement product interest, purchasing plans and follow-up records. After continuous updating, the company's data will become clearer and clearer, and sales will not have to start from the original unorganized form every time.

What the number quality inspection really solves is enterprise data"It looks like a lot but is actually difficult to use". By first unifying the number format and cleaning up duplicate information, then filtering target social platform users through Digital Planet, and finally classifying them based on customer sources and business tags, companies can transform a large number of overseas mobile phone numbers into cleaner, clearer and easier-to-execute marketing resources.
