After the overseas mobile phone number is reassigned, can the historical customer information continue to be used?

Just because an overseas mobile phone number can be connected normally does not mean that there is still the original customer behind the number.

After a customer deactivates a number, the carrier typically takes a period of time before putting the number back on the market. After new users get their numbers, they may continue to registerApplications such as WhatsApp and Telegram. From the enterprise backend, the number has not changed and the account is shown to be activated, but the actual user has been changed.

Therefore, historical customer information can be retained, but it should not be directly used for marketing, order notifications or after-sales communications before the identity is confirmed.

Numbers are reassigned and old customer relationships will not be transferred together.

Number reassignment is not a rare abnormal situation, but the operator's normal number recycling mechanism. The U.S. Federal Communications Commission also established a specialThe "Reassignment Number Database" helps companies determine whether the number has changed users after a certain date, reducing the chance of contacting the wrong person.FCC related instructions

For enterprises, the problem is not just that the information cannot be sent to the original customers. A greater risk is sending customer names, order contents, shipping information or after-sales records to the new owner of the number.

Especially for overseas customers who have not been contacted for several months, even if the number is still valid, it cannot be assumed that their identity has not changed.

First use Digital Planet to review the current status of the number

Before re-enabling historical customer data, you can first check whether the number is currently valid through Digital Planet.

Digital Planet supports empty number detection, which can help enterprises identify numbers that have expired, are down, or are currently not in use. Excluding invalid numbers first can reduce meaningless text messages, phone calls, and platform messages.

If the original main passTo contact customers via WhatsApp, you can also use Digital Planet to detect whether the number has opened WhatsApp, and combine it with information such as active status and risk status to determine whether this communication portal is still available.

Telegram and other supported platforms can also be detected along the same lines. What this solves is "whether this number can still be contacted now", but it cannot directly prove "whether the person using the number is still the original customer".

WhatsApp is still open and cannot be directly recognized as the original customer

After the number is reassigned, new users may use it to re-registerWhatsApp. Therefore, when Digital Planet detects that the account has been opened, it can only mean that the current number is associated with the WhatsApp account, but it cannot mean that the account belongs to the customer in the company's records.

Enterprises can use Digital Planet to complete the first round of status screening:

lIf the number is empty or unavailable, contact will be stopped;

lNumbers that have not been activated on the original communication platform will not use the original platform label for the time being;

lNumbers that have been activated and are in normal status will enter the identity confirmation process;

lAccounts with obvious risk status will be reviewed individually before deciding whether to contact them.

This way of handling is better than seeingIt is safer to send marketing information directly to "already activated", and it can also avoid mistakenly applying historical customer portraits to new users.

When it comes to orders and after-sales, identity must be confirmed first

If the number is associated with orders, membership rights, payment records or after-sales information, do not directly disclose sensitive content when contacting for the first time.

You can send a confirmation message without privacy first, for example:

"Hello, have you used this mobile phone number on our platform before? If you want to continue to receive orders or service information, please complete the confirmation through the original email or website account."

Identity confirmation is best accomplished by combining the original registered email address, website account number, order number, or information actively provided by the customer. Just because the other party can receive the message does not mean the verification is passed.

Historical customer data can be processed in three situations:

Digital Planet detection shows that the number is valid, the platform status is normal, and the customer has completed identity confirmation through other information and can continue to use the original customer information.

When the number is valid but the identity has not been confirmed, only the number status and test results will be retained. Do not directly use the original name, consumption preferences and order information for marketing.

If Digital Planet detects that the number is empty, the platform is not activated, or the status is abnormal, subsequent access to the number should be suspended, and then other portals such as email addresses and website accounts that the customer has previously authorized should be tried.

After the overseas mobile phone number is reassigned, the historical data is not completely unusable, but re-confirmation cannot be skipped. Digital Planet can help companies see whether the number is valid, whether the social platform is open, and the current status of the account, and screen out obviously invalid or abnormal data in advance; as for whether the number is still the original customer, it needs to be verified again through reliable identity information.
