Essential for data operations: Use Dingdang Assistant area code query to improve the quality and usability of international number data

Preface

Cross-border enterprises are collecting more and more overseas user data, but "available data" and "raw data" are never the same thing.
A large amount of data often has the following conditions: the country field is missing, the area code is confusing or wrong, the mobile phone number is not written uniformly, different writing methods of the same country are mixed, and the batch number format is messy and difficult to classify.

For the data operations team, the standardization of cross-border number data is the basis for all subsequent refined operations.
The Dingdang Assistant area code query tool is the most basic but most important "first piece of the puzzle" in this link.

Why is the "number field" the hardest when dealing with international user data?

International data is difficult to process because:

1. The number format is complex and varies greatly from country to country.

Some countries' area codes are very long, some numbers have a fixed length, some countries never start with 0, and some countries often use spaces to write in sections. If the team makes judgments based on experience, it is almost impossible to be 100% accurate.

2. Data sources are messy and form-filling habits vary widely.

Users come from different advertising channels, landing pages, and sources of lead cooperation: some fill in the area code but write it wrong, some only write the mobile phone number, some write the country name but no number prefix, and some write content with mixed formats from multiple countries. The data operations team must complete "cleaning" before the subsequent marketing team can launch or follow up.

3. Wrong area code will cause all subsequent actions to fail.

For example: SMS marketing → cannot be delivered; WhatsApp → cannot establish a conversation; outbound calls → cannot be dialed; CRM user portrait → wrong region label. Therefore, "correct area code" is not a formality, but the underlying foundation that affects the entire cross-border business chain.

How does the Dingdang Assistant area code query tool improve data quality?

Dingdang Assistant provides the data operation team with an area code library that is “always accurate and verifiable at any time” to help the team reduce uncertainty in the data governance process.

1. As the first step in number cleaning: quickly confirm the corresponding country code.

When the team gets a batch of user data, they can directly query it through the area code: determine which country the prefix in the number belongs to, determine whether it matches the area code format of the database, and quickly identify illegal or wrong formats. It is faster and more unified than manual search, and there will be no problem of two members reaching different judgments.

2. Make data standardization more controllable: the team uses the same set of standards

A common problem is that different employees use different area code tables online, causing discrepancies. Dingdang Assistant provides a unified and continuously updated area code library to make the data calibration standards of the entire team consistent, so that data governance results no longer rely on personal experience, but rely on tools.

3. Reduce incorrect numbers stored in the system and improve CRM/ERP data quality

Before the data enters the CRM, data warehouse, and marketing automation system, the number format must be confirmed through the area code tool, which can greatly reduce the problem of data pollution in the system. This is especially important for performing the following tasks: user nationality tagging, regional delivery analysis, and customer journey scheduling. Clean data can support more accurate regional strategies.

4. Simplify data rule formulation: newcomers can quickly understand the number system

There are a lot of rules to develop for data operations, but international number formats are too complex. Through the Dingdang Assistant area code query, newcomers can perform cleaning tasks according to tool standards without fully understanding all country formats, reducing training costs.

Typical usage scenarios of data operations teams

Scenario 1: Batch proofread country area codes before data cleaning

The team needs to determine which countries the user list comes from. With the help of the area code query tool, you can quickly confirm whether the area code is correct for follow-up: country, time zone, and market strategies. This is the first step in data governance.

Scenario 2: Quality inspection before importing new list into CRM

Before importing into the system, you can use the area code tool to check whether the area code actually exists, whether it conforms to the number format length of the country, and whether the wrong country is filled in. Reduce erroneous data entering the system.

Scenario 3: Determining country origin when analyzing ad lead quality

Advertising traffic comes from many regions around the world. Area code query can help the team quickly identify: which regions have fluctuating lead costs, which regions have a high proportion of invalid numbers, and which delivery channels have fake numbers. Make operations personnel more efficient in data analysis.

Conclusion

For cross-border enterprises, the higher the quality of data, the more accurate marketing, sales, customer service, and product decisions will be. International phone numbers are the most confusing part.

Dingdang Assistant area code query tool helps the data operation team:

✔ Establish unified data processing standards ✔ Improve number cleaning efficiency ✔ Avoid incorrect numbers from contaminating the system ✔ Improve the credibility of cross-border user data

This is a small tool, but it is an indispensable standardization cornerstone in the data governance chain.
